Hi elevandowski, I hope I can help!

Try going to "Options", then click the privacy tab, then see if, under history, you have "Never remember history". If so, try changing that to "Remember history".

If you have any questions, ask them and I will attempt to answer them!

Thanks, Tudor.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

It is possible that there is a problem with the key3.db file (encryption key) and the logins.json file (encrypted names and passwords) in Firefox. You can rename the key3.db file (key3.db.old) and logins.json file (logins.json.old) or move these files to another folder to make it possible to undo the action. Rename or delete a possible signons.sqlite file (signons.sqlite.old) used by older Firefox versions as well. You need to set a new Master Password after renaming or deleting key3.db and all currently saved passwords are lost. If that has worked then you can remove the renamed files that are no longer needed.

You can use this button to go to the current Firefox profile folder:
