Hello, When returning to my computer, I attempted to open Firefox and received a prompt to either start Firefox in safe mode or reset it. I tried safe mode at first then proceeded to reset it as well. Losing all of my add-ons/extensions/etc, I tried to solve the problem by restoring my profile with a folder that appeared on my desktop titled "Old Firefox Data". After following instructions to restore my profile, a window now pops up saying that my profile could not be loaded and Firefox just does not open at all. Is there anyway to recover my old profile? I tried following another suggested method but when searing for my profile through the files, it could not be found. Thank you!

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.
