Every time I request firefox an error box comes up, {JavaScript Application} TypeError: Components.classes[cid] is undefined

Is this an error in FireFox or JavaScript

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

  • Since upgrading to 4.01, I get an error message: [JavaScript Application] TypeError: Components. classes [cid] is undefined.

    I seem to have screwed up my Firefox, I guess. Whenever I go out of Firefox and try to come back in, I get that message, I click on OK and everything is fine again until I close our Firefox and try to return... What's the problem?

    Usually caused by an incompatible extension.

  • Cannot print from webpages. JavaScript Application TypeError: Components.classes [cid] is undefined message appears everytime I start Firefox. How do I fix this? Thanks!

    I wanted to install the Google toolbar extension, so I installed Add-on Compatibility Reporter 0.9.2. Then I installed the Google toolbar extension. When I restarted my computer I got this message. The Google toolbar did not work, so I disabled it thinking that would correct the problem. How can I get back the ability to print webpages. Thanks

    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
    If you haven't done yet then you should create a new profile exclusively for the 4.0 beta version and create a desktop shortcut with -P "profile" appended to the target to launch that profile.

  • When I launch Firefox 4.0 I get the following message "TypeError: Components.classes[cid]is undefined. How do I fix this?

    When I click "ok" the pop up window clears and FireFox opens. I believe this error is also preventing Privacy Protect from activating in FireFox.

    This is probably due to an add-on that is not compatible with Firefox 4. For details of how to troubleshoot that see https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes

  • What can I do about this: After upgrading to firefox 6, I get this error. TypeError: Components.classes[cid] is undefined???

    What can I do about this:
    After upgrading to firefox 6, I get this error.
    When I click to open Firefox, A box open with the following error:
    JAVASCRIPT Application
    TypeError: Components.classes[cid] is undefined?
    After I click close on the box, then Firefox will start. I really just want to get the error fixed so that when I want firefox open, I don't have to see this box anymore.

    You need to figure out which add-on is causing that error and disable it until the developer of that add-on fixes it. There may be an error message about that in the Error Console, accessed through the Web Developer menu item or through {Ctrl + Shft + J}.

  • Get error "TypeError: Components.classes[cid] is undefined" and can't load web pages. Problem with Firefox 5?

    I tried repeatedly to load Firefox 5. The Error "TypeError: Components.classes[cid] is undefined" keeps coming up. The browser loads but any URL I enter doesn't load. Sites activated by buttons do load. Internet Explorer works.

    07-05-11 When I turned on my laptop (Vista) this morning, I got a Start in Safe Mode and Repair message so I did. It suggested a System Restore, I hit OK. When it started like normal, I waited a few minutes then TRIED to launch Firefox 5.0 but kept getting a Mozilla Crash Report dialogue. So I instead opened Firefox 4.0b12 --error free-- so I could get here to get help. When I tried the Run... firefox.exe -profilemanager step, I get the subject error. When I try to open FF 5.0 in Safe Mode by holding down the shift key simultaneously, I get the subject error and no launch (though no Crash box either). I will try to let the FF 5.0 Updater run when it appears again but it never lets me choose when to Ask Again so I don't think it'll show again until tomorrow. Sigh. Oh, and like someone at a different version of this error blog re WinVista 32bit, now I'm getting the issue of Enter not executing the URL typed in the address bar; I had to click the arrow.
    I hope the Update is to fix this problem.

  • Firefox 4.0 displays an error code when launching: "TypeError: Components.classes[cid] is undefined", add-ons doesn't work and I can't open any web pages

    Hello
    I've been running Firefox 3.6.16 with no problems at all, and this morning decided to upgrade to Firefox 4.0, as the developer of the them I use, Foxscape, has upgraded it to work with 4.0. The installation appeared to be as normal, but when I launched 4.0, the following error message appeared: error "when launching firefox 4.0 TypeError: Components.classes[cid] is undefined". The browser launched, but while I could go to webpages if they were in my bookmarks, so no problems with my internet connection, but when I typed in a URL (for example google.co.uk) and pressed "go", nothing happened. Similarly, when I tried to go to add-ons, it was as if I hadn't clicked anything. I wondered whether it was an issue with Foxscape (although I've never had any problems before when upgrading, as the standard theme just appears) so I reverted to 3.6.16, switched the theme to standard, then tried upgrading to 4.0 again. The same thing happened, so I'm positive it's got nothing to do with Foxscape.
    I run Windows Vista Home Edition on a Dell Inspiron. I also have IE 9 installed (I installed it a few weeks ago, and it's been running fine with 3.6.16). I've never had any problems with Firefox before; I'm very keen to upgrade to 4.0, and would appreciate your help in fixing this.
    Thanks

  • After I downloaded Firefox 4 and I try to open Firefox, I get this error message, "plug-in object: TypeError: Components.classes[cid] is undefined". I click "OK"; Firefox opens and works just fine. Any suggestions??

    Not much to add. Before Firefox will open, I get this error message, "plug-in object: TypeError: Components.classes[cid] is undefined". I click the "OK" button; Firefox opens and I have no further problems.
    I use an Apple with OS v. 10.6.7 and had no problems until I downloaded Firefox 4.0
