The error "TypeError: Components.classes[cid] is undefined" is probably caused by an extension, maybe XPL Link scanner.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

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. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

In my case, it was AVG Safe Search.

Particularly annoying because this was certainly disabled when I installed b9 but I notice it is showing as enabled (by itself, not by me) on both of my machines.

Why does this extension not have a "remove" button?

Why does firefox *allow* AVG to install uninvited extensions, enable them without asking ? Can't firefox blacklist extensions that do this and prevent them from being installed at all ?

In my case, disabling the Esnips Downloader Extension solved the problem.

What a rogue extension! I had been getting this error from the last one month or so but I never tried to single out the offending extension by using the safe mode option due to laziness. But it was only today that I decided to isolate the problem if it was due to some addon, and succeeded. I never wanted to install it from the very beginning but esnips.com would not let me download anything from their site without installing the Esnips Downloader.

On my laptop, the culprit was "OneClick YouTube Downloader", version 1.0.6. I believe it came with Orbit Downloader, a standalone app. Once I disabled this addon, the error went away.

Regarding "TypeError:Components.classes[cid] is undefined" on Firefox 4 and 5, I went into Safe Mode and disabled Google Update 1.3.21.57. Then I went back into regular mode and Firefox opened without any problems. There is a recent online headline, "After Six Years, Google Drops Support for Toolbar on Firefox." I hope this information helps some of you.

After weeks of going round in circles & being told by Talktalk that it was a Microsoft problem, I now realise that it is because certain things are NOT COMPATIBLE i.e. they are competitive & don't want to support each other ! My problem turned out to be that I would prefer a Google toolbar as I'm in my 80s, not a youngster so do not want the AOL toolbar. Firefox does not want to support Google, or vice versa, so they make life difficult for you till you lose Google toolbar & Bingo ! no more TypeError etc etc. Now I go STRAIGHT to my webmail page or website link !!! Go to the Add-ons & plugins page & see what is not 'compatible' & THAT'S your culprit !
