Two new problems: Most recent is

"firefox having trouble restoring your pages...start new session"   

And...for several months, anything I print from website (i.e credit card statement) is in HUGE type that doesn't even come close to fitting the page. This does not happen when I print from Edge, nor when printing documents (pdf, notepad or anything NOT from a website), so the problem has to be in Firefox.

You may have corrupt sessionstore [v56] sessionstore.jsonlz4 file(s). Delete all sessionstore* files and the sessionstore-backups folder.

Don't delete the files if you need to rescue any data from them, just move them out of the profile folder to some location where Firefox doesn't look for them. You can try to read out their contents using this tool: https://www.jeffersonscher.com/res/scrounger.html


Type about:support<enter> in the address box.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Locate the above file. Then rename or delete it. Restart Firefox.

Try using Print Preview first, and adjust what you need.
