FlipClock-Firefox Add-On

February 23rd, 2010
Latest version: 0.82 Download

Flip Clock is an official Firefox extension that adds a stylized clock to your browser status bar, which is the bar that runs along the bottom of your browser window. The time appears in your browser’s status bar:

Flipclock displays the time in your Firefox status bar

FlipClock does not do anything other than tell the time, and look stylish. The clock preferences have been translated into Spanish, German, French, Portuguese, and Russian. Clicking the clock allows you to select from a wide range of options, including changing the style of the clock to one of the following:

Flipclock displays the time in your Firefox status bar

  • Flip Clock
  • LCD Clock (Amber or Green)
  • Nixie Clock
  • Bar Code Clock
  • LED Transponder Clock

Options also include the display of seconds, AM/PM and 12 or 24 hours display.


Latest Update

Version 0.82:
This update fixes a number of issues with the preferences window not working. There was no version 0.81 (problem with an upload to the Mozilla site).

Past Updates

Version 0.80:
This version will fixes an error message that some users experienced when opening the preferences window for the first time. The previous error message could be usually be fixed by selecting a clock style and closing the preferences window.

Version 0.79:
This version adds two new clock styles: wooden tiles that resemble the game Scrabble, and red punch tape. Under the hood, the add-on was significantly updated to use a single image file per clock style for all digits. From this version on, new clock styles will be significantly easier to modify and create.

Version 0.78:
The clock’s installer was updated to indicate that it will work with the upcoming Firefox version 3.6.

Version 0.77:
The LCD and LED clocks were updated to a more photo-realistic design.

Version 0.76:
This update only reduces the number of internal developer warnings that only I see on the Firefox add-on site. Check out the version 0.75 update, which fixes a number of OS X display issues.

Version 0.75:
This version fixes a few display issues on OS X. Mac users will notice a full sized clock now (16 pixels high) and the options window is no longer clipped off at the bottom.

Version 0.74:
This version adds Portuguese and Russian translations and fixes the German translation (my fault.) Thank you to both Adriana Sesana for the Portuguese translation and her husband Anton Semenovsky for the Russian translation.

Version 0.73:
This version adds two new clock styles, including a legal pad clock and a scoreboard style clock. Also, German and French translations have been included in this version. Thanks to Bastien Frediani and Thomas Sturm for their translations. If there are a few translation mistakes, they are likely my fault as I translated a few new words in the last minute.

Version 0.72:
This version adds a few new clock styles, including a barcode clock and a punch tape style clock. Also, a few small OS X (Macintosh) issues from the previous version have also been ironed out. The options panel has been translated into Spanish with this version thanks to Katia Rubio, so those with Spanish language browsers should be able to see all written text in their preferred language. Other languages, including German and French, are in the works.

Version 0.71 created and submitted to Firefox for approval.

Version 0.71:

  • fixes a few OSX issues involving the preference pane
  • fixes a Firefox 3.0 issue involving the preference pane
  • includes a new “odometer” clock style
  • moves all readable text into the en-US directory in preparation for a multi-lingual version.

    Good job, but I miss a 12/24 hour choose option.

    Currently Flipclock just show hour in 12-hour style. And I used to 24-hour style.

    FlipClock should have a checkbox in the preferences labeled “Use 24 Hour Clock”. Checking the checkbox will result in a 24 hour (miliary-style) clock. One version of FlipClock had a bug where that feature would not work, but the latest version 0.74 should be fully functional for both time display options. If the latest version is not working for you please let me know what browser version and operating system you are using and I will attempt to reproduce the issue and fix it.

    Awesome clock add-on for Firefox, I just installed on the latest Firefox and FlipClock works great! I do have a request for a few new clock styles that would be cool and increase your user base:

    1. Hebrew Clock:
    A clock using Hebrew letters as numerical digits, this would be a fun and different clock since Hebrew is read ‘right to left’ instead of ‘left to right’ the hours would need to be on the right and the seconds on the left(or it could remain ‘left to right’ if easier), also because there’s no “zero”, the seconds below 10 would be just one digit or just use “0″ as a placeholder. For more explanation of Hebrew numerals go here: http://en.wikipedia.org/wiki/Hebrew_numerals

    2. Japanese Clock:
    A clock using Japanese numerals:

    3. Chem Time Clock:
    On the Chem Time clock, numbers have been replaced by the symbols of the corresponding element, since each element has been assigned a number, called its atomic number this is used instead of numbers.
    Reference: http://scifun.chem.wisc.edu/ChemTime/ChemTime.html

    Thanks for the great Firefox Add-on: FlipClock!

    Excellent suggestions, thanks!
    The Japanese digits and table of elements digits would be pretty easy to do. I’ll have to consult a Japanese friend for advice on digits. I’ll probably try it with the Black FlipClock style.I just completed a Scrabble digits style last week and I am pondering whether to add it or not (I’m not sure if it is quite good enough design-wise).

    Scrabble Clock

    The Hebrew clock would be very difficult because the clock is all set up for time in the left-to-right 12:34 56 format with 12×16 pixel graphics for digits.

    I am polishing an analog clock Firefox add-on that I will likely add to the Firefox site soon. It is a very small analog clock that goes in your status bar (just 20 by 20 pixels on the PC).

    I also received a suggestion that I add the date as an option to precede the clock. I’ll play with that when I get some time, perhaps an evening next week.

    @Christopher Ditto
    I’m glad you like the ideas!

    I actually like the scrabble digit style; it would look good in a steam punk type Firefox Theme, not my style but somebody may love it. It is good to give people choices.

    The Hebrew Clock would be pretty easy for you to implement also. Just keep the standard left-to-right configuration, and place Hebrew Numerical Letters for digits. For example 12:34 would look like this:

    The rest of the Hebrew digits would be easy to place into this system:
    0 – 0
    א – 1
    ב – 2
    ג – 3
    ד – 4
    ה – 5
    ו – 6
    ז – 7
    ח – 8
    ט – 9

    The Hebrew Clock would be cool to see, perhaps in the FlipClock White.

    Anyway, I look forward to all your new editions (Japanese Digits, Chemistry Clock, Hebrew Clock, and Scrabble Digit Clock) and will help spread the word about this awesome new Firefox Add-on.

    Thanks Again!

    I need it for some duties in a browsergame called Ogame to see the exact time. it works realy fine for me!! Thank you!!

    I also like the Scrabble Idea ;)

    My only request is to implement a Stopwatchfunction, I think this would be interesting for a bunch of people, too…

    I currently use flipclock and it is an ad that I like.
    But I have an Sugestion.
    The possibility of putting in a transparent background and can also can move it where you wish in the task bar or in the personal bar of firefox.
    Is this possible?

    what do you think?

    PS:sorry for my English I’m French

  8. November 6th, 2009 at 09:42 | #8

    Thank you. Two excellent suggestions. A transparent background is no problem, what clock do you think would be best with a transparent background?

  9. November 6th, 2009 at 09:43 | #9

    I am still planning on adding additional clock styles, such as hebrew and Scrabble, I just need a full weekend afternoon to create these.

    I downloaded an apparently buggy (on my system at least) FlipClock 0.77 from Firefox and then downloaded 0.78 from you. In both cases, even though the “include seconds” and “include AM/PM” boxes were not checked, I got both anyway in the display. No amount of checking, unchecking, disabling, abling, deleting, reaquiring and many reboots would get rid of them. Have you heard of this happening? I have Firefox 3.5.5.

    The clock is great, but for some reason I can’t get the 12/24 hour format to work. I have the latest version (0.78) and even when I change between formats the 12 hour format remains….
    I hope there is a fix for this!!!!
    Again, great app!!!!

    There seems to be an issue with some preference settings not sticking. I haven’t been able to reproduce the problem, but at least two or three people have told me about it. I’ve tried just about everything to duplicate it, using the same OS and version of Firefox, but it just won’t stop working for me to fix it. I’ve heard restarting Firefox after the initial install helps.

    As best as I can translate (via Google), this Hungarian sentence reads, “Unfortunately, I can not watch the show! I would appreciate if someone could help in this. Thank you.”

    I would love to help, but I do not understand. Anyone?

    Szeretném tudni, hogy, hogy működik ha minden rendben van. (Flip Clock version: 0,78)

    BUG – Clock Locks Up

    I’m on a WinXPPro machine. I had a firefox window open with the flipclock running (LED-Green, Show Seconds, Show AM/PM), I noticed my system clock was off so I manually updated it (double clicking on the systray clock and setting it from 9:27am to 9:22am) as soon as I hit OK the flipclock froze at 9:22:50am and had to close the browser and reopen it to get it to run again. Not a big deal, just figure you might want to check it out.

  20. January 2nd, 2010 at 18:22 | #20

    Thanks for posting this! I will take a look when I’m back in front of an XP machine (in a few days).

  21. January 6th, 2010 at 14:39 | #21

    I am able to reproduce this on my machine, but only when I turn the time back. Turning the time forward seems to work correctly. This is quite a mysterious bug that you have found. My other Firefox add on, AnalogClock, doesn’t appear to have this problem. I will work on it.

    12/24hr time display

    Can’t get my 12/24hr option to work. I have a Mac OS X 10.4 system and a 3.5.7 version of Firefox. Otherwise I love it all especially the bar code style.

    January 17th, 2010 at 08:09 | #24

    Hey I love your clock and all the options but having a few issues. Im on a netbook running win7 starter and latest Firefox.

    1. Can’t really turn off seconds at all, no matter where box is checked.
    2. I use 24hr time which works great, but am/pm still shows up.

    Am I missing something? Just want to get rid of seconds and the am/pm. Seems like it should be simple.

    Thanks for a handy little extension!

  25. January 28th, 2010 at 15:58 | #25

    I get this:

    error:[Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref]” nsresult: “0x8000ffff (NS_ERROR_UNEXPECTED)” location: “JS frame :: chrome://flipclock/content/js/options.js :: anonymous :: line 48″ data: no]

    When right or left clicking on the statusbar…
    Had to uninstall it immediately unfortunately… :-(

  26. January 28th, 2010 at 17:15 | #26

    Thanks for the post! I’m learning to really despise the way that Firefox handles/remembers user preferences and I haven’t been able to reproduce problems like this that I have been hearing about. This does give me a clue, however, and it has me thinking…

  27. January 29th, 2010 at 12:18 | #27

    Aha! I think I’ve figured it out. When browsing in “Private Browsing” mode, Firefox won’t allow add-on applications (like FlipClock) to access the preferences functionality. Firefox simply throws an error. I believe that I now have what I need to fix this. When I get a fix finished I’ll post it here and with the Firefox site and everyone will be automatically prompted to update.

    A very nice clock. How do I turn off the seconds? I only want hours and minutes.


  29. February 12th, 2010 at 15:12 | #29

    I was finally able to reproduce the error and I have uploaded a new version to the Mozilla add on site (version 0.80), also available at the top of this page. This new version should fix the error that you were seeing. I apologize for taking so long it was very tricky to reproduce, even though it was showing up for some first time users. It may take a day or so on the Mozilla add on site for the new version 0.80 to appear, but you can install it from this page right now if you wish.

  30. February 12th, 2010 at 15:20 | #30

    @Christopher Ditto
    I was mistaken. The problem was that when a first time user used it for the first time, the add on wasn’t able to figure out what clock style to display. I changed the way that default settings are set and the error message should disappear with version 0.80.

    February 18th, 2010 at 07:24 | #31

    Nice extension for FF. Sadly 24h-option seems to be broken in 0.80 (was ok in 0.79). Ubuntu 9.10 & Firefox 3.6.1pre.

  32. Paul
    February 18th, 2010 at 14:41 | #32

    I just installed 0.80 and the Seconds check box still does not work. The check box hasn’t had any effect for the past couple of versions. I like the clock on the browser because I autohide my taskbar, but seeing the seconds tick away is really annoying sometimes because it doesn’t flip at a constant speed.

  33. February 19th, 2010 at 17:16 | #33

    I just managed to reproduce this issue on a new Mac so I should have it fixed within a week (will be version 0.81). If I don’t get a new version done, I’ll email you a custom-built version with seconds hidden by default.

  34. February 19th, 2010 at 17:18 | #34

    I will take a look at this. I haven’t tested FlipClock on Ubuntu but I have it installed on a memory stick. Strange that it stopped working. I didn’t change any code with version 0.80, I just added a file that sets the default values for everything so this is mysterious.

    I believe the latest version 0.82 fixes this and several other issues. It is queued up for Mozilla approval right now, which may take a day or two. In the meantime, the version currently linked from this page is the latest (0.82).

  39. February 23rd, 2010 at 22:04 | #39

    Thanks for pointing this out. I believe that today’s version 0.82 fixes this and several other issues. It is queued up for Mozilla approval right now, which may take a day or two. In the meantime, the version currently linked from this page is the latest (0.82).

    Thanks for sharing this, I didn’t know about this major bug until the comments started appearing on this page. I believe that today’s version 0.82 fixes this and several other issues.

    At the risk of duplicating other comments here regarding this… the issue should now be fixed with the latest update. It is queued up for Mozilla approval right now, which may take a day or two. In the meantime, the version currently linked from this page is the latest (0.82).

  42. February 23rd, 2010 at 22:09 | #42

    A fixed version is available from this page, and will be available from Mozilla as soon as they approve the update. It will appear as 0.82 when it is approved. Thanks for taking the time to share this issue with me.

    I’m running Firefox in Win 7. When Flip Clock updated to the new version, it stopped showing up on the status bar. It seems to be working ok on my XP and Vista machines … just not on this Win 7 box. (FlagFox isn’t working here either.)

  44. March 1st, 2010 at 17:27 | #44

    I’ll try to look at this on Windows 7 when I can get my hands on a Windows 7 machine.

    @Christopher Ditto

    Is your clock Java based? I seem to be having trouble with Java apps through Firefox, so it might not be your program. I’m not sure what the problem is. Flagfox and the analog clock tool aren’t working, but Weather.com’s add-on is. I’m having trouble with Java driven message and mail pages at school.

    Something’s screwed up, but I don’t think it’s your clock anymore. It may be Java, Firefox, or my machine.

    We’ll see.

    (really cool clock, by the way.)

  46. March 2nd, 2010 at 21:44 | #46

    The clock isn’t Java-based. It is written in XUL (pronounced zool), which is a language a little like HTML with some JavaScript thrown in. Firefox itself is written in XUL. All Firefox add ons are written in XUL, but some have some Java code mixed in. FlipClock doesn’t need Java.

    I LOVED your clock!
    It’s getting the job done in such an elegant way and it’s also nice that you can change it altogether to a completely different feel.
    I love the desings, the options.
    Not very crowded but very efficient!
    Absolutely brilliant!
