I updated FF and now my bank (Capital One) just yields blank pages once I log in. Nothing displays. I tried troubleshooting mode to no avail. It happens with other legit web pages too. How do I fix this? They display fine in Edge. Open H264 Video Codec and Widevine are my only two plugins. I tried disabling the tracker to no avail either.

I'm running on a high performance Win 10 PC.

You can check the Web Console (Tools -> Web Developer) for relevant-looking messages.

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.

You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data for that website will be saved once again.

What's the easiest, safest way to back up the data, and how difficult is recovery if I need to put it back?

And here are the messages I got from Web Console:

Analysis?

Thanks.
