ok.. so today firefox decided it no longer wanted to work after my computer updated, i've completely wiped it from my computer (laptop, THANKFULLY my desk top is still working) and uninstalled/reinstalled it easily a dozen times... with either the "couldn't find XPCOM" error or "mozglue.dll was not found" error.

i no longer know what to do. none of the help pages are helping. i'm getting very frustrated and if there was another browser out there that wasn't crap i'd switch over to it. at this point i dont even care if i lose my bookmarks i jsut want to be able to use my stupid computer without the hassle of trying to use chrome or opera or whatever. i LIKE firefox but this is getting stupid.

Did you do a clean reinstall and removed the files and folders in both locations?

  • (64 bit Firefox) "C:\Program Files\Mozilla Firefox\"
  • (32 bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"

Firefox will normally install the 64-bit Firefox version on a 64-bit Windows platform.

You can try to install Firefox in Windows Safe Mode to see whether that works.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen or hold down the Shift key) to see whether that has effect.
