Firefox Community Forum

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Hello. I was reading Quora.com web site on my notebook in Firefox (110.0.1 64-bit) normally, then I got power outage. When electricity returned and I tried to open it again, browser didn't open it and I gave me message:

Secure Connection Failed

An error occurred during a connection to www.quora.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

I've tried to get support from Quora.com how message said, but they told me "this error does not originate from our website". And gave me some suggestions - "The easiest way to fix this secure connection error is to reset the Firefox settings." I've performed "Refresh Firefox", but problem persists. I don't use VPN. Can anyone please help me with this problem?
