Why doesn't my back button work?
I recently reset my Firefox because links weren't working in several sites. Now my back button doesn't work (it's grayed out) and the browser no longer remembers--or even shows--the sites I visit. E.G. when I'm typing a URL into the navigation bar, it no longer fills in common sites, and when I click on links within a site the address of the linked page says about:blank rather than the real URL.

Hello,
Try see this help article:
Try also start Firefox in Safe Mode:
To remember and fill the urls you need to allow the option to remember history, to do this, go to Tools >> Options >> Privacy >> Firefox will: change to Remember history
Also:
Problems with bookmarks and history not working properly can be caused by a corrupted places.sqlite database file.
You can check for problems with the places.sqlite database file in the Firefox profile folder.
Thank you both!
