Any Firefox experts on line?

By VAR1016 ·
Hello all.

Following a system restore that I carried out for unrelated reasons, Firefox has gone "on the blink" here. On trying to open a bookmark I get a dialogue box that reads "Launch Application", "this link needs to be opened with an application". There is a button marked "choose"

I have uninstalled and reinstalled Firefox (3.6.3) to no avail. I performed another System Restore again to no effect.


Thanks in advance.

Re-set your .url file extension to open with firefox.

This is a video I made for another user with a similar problem.

Great helpful video, but sadly when I follow the instructions "change" button is greyed out and I am asked to click on "advanced" which does not offer the change option.

At present internet shortcuts have nothing to open them, however the problem is only in Firefox, shortcuts do work in Chrome and IE8 but I prefer Firefox!

Uninstall and reinstall IE8, then reinstall Firefox

And then set firefox as your default. This should correct the file associations.

How does one uninstall/reinstall IE8? "Add or remove Windows components" merely seems to remove start menu and desktop access.

I have XP Pro SP3

I haven't tried, but I suspect simply re-running the IE8 installer will offer an option to reinstall it.

WRT reinstalling FF

The problem is likely in your Profile, which does not get deleted when you uninstall/re-install.

Backup your profile, delete it, and add items back in to a new profile one at a time until you find the one that kills the bookmarks.

Or just start over with a fresh profile, and import your bookmarks and passwords.

Thank you

Yes thanks, this worked; I really did not want to lose all my passwords, add-ons etc. Of course I saved my bookmarks and imported them, so it's not a total disaster, but annoying. I have to wonder what caused the problem in the first place

Thanks again and to all who replied.

Pull your passwords out.

You can reclaim most of your personal-use stuff from the profile without risking putting back the broken stuff. You can even use the SQLite extension to play around with those databases.

FEBE and CLEO are good profile backup extensions, or you can use MozBackup (standalone app) for easy backup/recovery.

Then reboot and see if that helps with your Firefox issue.
