Since upgrading to 6 I get "TypeError: Components.classes[cid] is undefined" when loading Firefox - why?
When loading Firefox or certain pages I get a message box appear with "TypeError: Components.classes[cid] is undefined" if I hit "OK" the system continues. This has only happened since the recent security upgrade to Firefox. I have downloaded Firefox and reinstalled but the message persists.
This issue can be caused by an extension that isn't working properly.
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).
*Don't make any changes on the Safe mode start window.

Also receiving this error when logging on to some websites. Able to close the error screen and continue but it is aggravating.
That indicates that you are using an add-on that is not compatible with Firefox 4. For details of how to troubleshoot this to find out what one is causing the problem see https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes

Everytime I open a window in Firefox 4 beta 2 I get a messeage that says TypeError: Components.classes(cid) is undefined, when I click OK it opens up the new window.
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).<br />
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]<br />
<br />
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.<br />
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.<br />
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")<br /> -
Since installing the newest version of Firefox, This message "TypeError: Components.classes[cid] is undefined" appears in a box when a new window should open. Also, what you see in print print preview is not what prints.
This type of error is usually caused by an add-on you are using that is not compatible. It could be anything from an antivirus link scanner like AVG Safe Search add-on, or McAfee Site Advisor add-on, or something similar. To confirm what add-on is causing this use the procedure in this link:
https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
Try Disabling the last add-on that was installed prior to upgrading to version 5.0
Check and tell if its working. -

After clicking [OK] in the Error-message Firefox runs without problems. It seems to be only annoying.

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}.

Only started since the upgrade. Windows Vista Home 32 bit.
The error message reads:
"TypeError:Components.classes[cid] is undefined."Try the suggested idea above. I just disabled all the add-ons which were not compatible with FF 5 and did a FF restart. That fixed the problem. I then enabled each one, one at a time, with a FF restart until the problem came back. I then disabled that add-on.

When I open up Mozilla i get this error message--TypeError: Components.classes[cid] is undefined

At the top it always says-- Java Script ApplicationThat error is caused by an incompatible/malfunctioning add-on.

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 4.0That indicates you have 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

I tried to uninstall AVG antiviral software, but it did not uninstall. Next, when I try to open Firefox I get a box popup that says:
TypeError: Components.classes[cid] is undefined.
If I click OK in that box, I can then open Firefox.
Also I can no longer update Java.
Help!Possibly you have "AVG Safe search" extension installed as part of "AVG Free", solution involves reinstalling :AVG Free" without the Link Scanner component see
