I started having some troubles with Mozilla firefox recently after we had our internet set up. The Browser will only load some pictures, and not all of them. It wont let me download any Plugins and only goes to websites half the time. Right now I'm having to use Internet Explorer on my desktop machine, even though firefox runs perfectly fine on my laptop. Has anyone here ever had this problem?

Are you running a beta release?

If so that might do it. Try downgrading.

The usual solution to weird firefox problems is to delete EVERYTHING and start over.
- Uninstall Firefox
- Delete C:\Program Files\Mozilla Firefox
- Delete C:\Documents and Settings\userprofile\Application Data\Mozilla
- Download the latest official build and re-install

That should clear it up.
