I :"refreshed" Firefox. PC seems a little faster but still slow functioning as compared to its speed one week ago. I now get Firefox message :"Firefox not responding,delete "old Firefox" to continue. What must one do to satisfy the Firefox program? I've had Firefox for about 8 months & the first 5 months were trouble free,the last 3 have been frustrating since installing ipdates to Firefox.

Download Firefox For All languages And Systems {web link} Save the file. Then;

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Mac: Open the "Applications" folder. Linux: Check your user manual.

Look for, and rename any Mozilla or Firefox folders by adding .old to them.

After rebooting the computer, run a registry scanner. Then run the installer. If all goes well, remove the OLD folders when you are done.
