Well, I have the latest version of Firefox.

However, when someone sends me a link of any kind (like over AIM), when I click on it, Firefox refuses to open.

Also, when I click the "Check for updates.." button on CCleaner Firefox won't open either.

It seems if I'm not clicking a link on a site, that Firefox will not open.

It used to work, but one day it just stopped.

Any thoughts?

Reinstalling it maybe? I don't really know because I haven't had a problem with FF 3 Beta 5 yet...

FireFox needs to be registered as your default browser.

Have a look here for some pointers:

I know it's already set as the default brower, so I guess I'll try and reinstall it.

Thanks for the help guys.

Dont bother reinstalling.
Firefox often will become corrupted sometimes and not be properly registered as your default browser. Easiest way to fix it is make IE your default browser. Then make firefox your default again and it should work.

It worked!

Thank you so much!

That's interesting. I never thought of something like that before. Typically I set no apps as 'default' but still all are accessable (if I have that choice) and let things be.

Are there certain Services that won't work unless an app is set as default?
