When I try to set FF back to default, I get XUL Runner: v. 15.0.1... What should I do?
I'm running XP Pro. System has been running extremely slow; have tried other options but no success. Tried to set FF back to default, but I get the message: XUL Runner Error: Platform version "15.0.1" is not compatible w/minVersion >=12.0, maxVersion <=12.0. Is there anything I should be doing to get rid of this Error? I am not very computer literate, so please try simplicity in explanation. Thanks.

hello hikerpat, this error might be caused by security programs such as zone alarm - please temporarily disable those programs and do a reinstall of the browser:
- download the full firefox 15.0.1 setup file from getfirefox.com
- uninstall firefox on the machine (but don't chose to delete your custom files & settings in the uninstaller)
- manually delete all remaining files in the firefox program folder, which usually resides in C:\Program Files\Mozilla Firefox\
- reinstall firefox
If you use ZoneAlarm Extreme Security then disable Virtualization and reinstall Firefox.
Other security software may have similar features to prevent Firefox from updating files properly.

As you suggested: I temporarily disabled (for 1 hour) Avast 7. I used your link to download a new copy of FF. I tried 3 times to open it to run it, but nothing happened. But, and this a huge problem - I lost use of the computer for over an hour, as the screen went to a bright silvery black/green. It came back up when I did Control*Alt*Delete. This happens very often. Thankfully, Avast 7 came back up to do due diligence. I will try this again - when I have several hours to devote. Thanks.
Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that works.
I don't know what "network support" means. What I get is: USB HDD; CD-ROM; HP Diagnostics; <F2> Enter Setup; <ESC> Summary; <F12> Boot on Lan; <F10> Run HP Diagnostics. I don't know what any of that means or what any of it does. If any of it involves having an install disc, I don't have one.
