Fixing “Chrome registration failed” error on Firefox

Posted by shannonclark on November 1, 2007

Since the update to Firefox I have been experiencing a problem of three “Chrome Registration Failed” error messages being presented to me every time I restarted Firefox.

With today’s update to Firefox I had hoped that the problem would have been resolved.

Nope. Instead it only got worse, whenever I tried to update my add-ins and then edit their options, the add-ins pane froze. Looking on I found one suggestion for a fix (delete the extensions.ini, extensions.cache and extensions.rdf files from your profile). On doing that however not only did it NOT fix my problem, but in fact it made it worse – every single add-in I had installed was reset to a “needs restart” and even after a restart the add-ins were not installing.

So on experimentation I tried the following:

(all this is on Windows Vista)

Right click on the Firefox icon on your desktop.

Select “run as administrator”

And poof – problems gone, all add-ins installed and working.

I then closed Firefox and restarted it (figured running as administrator is not a good general practice).

But count me as in the “pox on both your houses” camp here – to both Microsoft and to Microsoft for having such a clunky OS that occasionally you have to run processes as administrator (i.e. as “root”). And for two serious bugs – first error messages that are BEYOND useless – reporting on an error WITHOUT NOTING WHAT CAUSED THE ERROR. And second, for building a USER application (a browser) which for some reason does something during the installation process of components (i.e. add-ins) which requires administrator rights.

Seriously bad coding somewhere.

And this is a case where Google failed me. Nothing I found after searching almost literally 100+ websites and online discussions had this fix, not even discussions on (which reported inaccurate fixes for this problem in fact).

So hopefully this will help someone and the last two hours of my life which was wasted on fixing this will at least help someone else.

Update – some of the comments make it clear I was unclear in the above. After initially running Firefox as administrator I have not had to do so again, something about that one running fixed what I can only suspect were either permissions or registry issues. This fix has survived reboots and subsequent installations of additional Firefox plugins. Glad it has been helpful to a few of you (about 100 people or so a day have been reading this due mostly to Google searches)

    thank you very much :), i prefer using firefox because its the fastest to use i believe and works best for me when using facebook, but i would have deleted it if it wasn’t for this helpful advice XD

    This worked for me. I really have appreciated using Firefox because it appears to be less prone to viruses like the explorer browser. When I started getting this error, I thought my good fortune had come to an end. I think this “fix” should be disseminated wider. Thanks shannonclark.

    This fix did not work for me and I use windows 7….unpinned FF from task bar and start up…ran as an admin…still get the dreaded Chrome error and then the add on window pops up but there is nothing to add…keeps saying restart FF…I have no idea what triggered this big and so far I have no fix…

    • by “run as admin” I didn’t mean reboot & login as admin but to right click and select the “run as admin” option (which is present in vista – don’t have a Windows7 machine to test this on) However others have reported success with the fix under Windows7.

      A few suggestions.

      1. Run the Windows 7 task manager (which I assume still exists) and make sure that Firefox is fully closed and not still running the background.

      2. Right click on Firefox (the icon/start menu item) and select “run as administrator”

      If this doesn’t work – launch another browser and go to Mozilla’s website and download the latest version of Firefox and run the installer – see if this fixes it.

      Good luck and hope you see this and it is helpful.

    Thanks a lot! I have been getting the chrome registration failed message for the last three days and I’ve been ignoring it because I didn’t think much of it, since I’m not extremely computer savvy and figured “well, whatever. nothing is happening.” I eventually became fed up with the messages and decided to google a way to fix it and here I am. Once more, thanks. ^^

  31. André said

    how can it be fixed on Mac?

    • Not sure. I haven’t seen it on a Mac before personally – did you get this directly on a Mac or on a Mac running a VM software or dual-booting? I would suggest starting with running a permissions check (Disk Utility, select your HD, run the verify permissions) which may help you.
