Sometimes, its the settings or something in the user profile that is causing the problem. The refresh / reset removes everything.

Look on your desktop. Do you see a folder called; Old Firefox?

These can't get your data back, but will help in the future.

These add-ons can be a great help by backing up and restoring Firefox

FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backup of files that you choose.

Refresh firefox caused more problems than it solved. I was shocked at the time that I had to waste restoring my settings. I believe it may be possible to write a refresh script that does not get rid of all custom settings and bookmarks.

I'll try the add-ons. I did use the Old Firefox file, but was still a hassle. It is odd that settings are allowed that could cause a problem. Evidently more conflict error checking needed. It is always easier to "re-image" rather than repair software or hardware, but always incurs restoration work that can be time consuming.

Glad to help. Safe Surfing.
