I am unable to recover the original profile files, and this is not me trying to recover that; they are just gone completely so, I can't bring that original profile back to fix this. I have refreshed, uninstalled, signed out, closed the tabs from my sync list, etc, but I can't get this to go away. I don't know what to do.

I'm away at another location for a few months out of the year. The computer in the other location is almost identical to this one, done in a very simple manner, by using a backup and then reinstalling everything from previous computer to current, most of which is data.

The Firefox profile is copied over and then the version of the program from that other computer is copied, so the profile and program match. The last step is to disable each add-on individually, then to immediately enable them again. (Otherwise, the browser won't connect to the internet.)

I followed the same procedure today as every single time. But then I noticed the blank new tab add-on isn't working. And upon looking at the add-ons...none of the enabled ones are listed (or working). Only the disabled and recommended ones. I don't even know which were installed, and would have a hell of a time figuring out which ones are supposed to be there, and how they're set up.

Where did they go, and how can they be reinstated?

This has never happened before, and I've been doing this same thing for at least 3 years.

Thanks in advance.

Attempted to update FF using the 140.2.0esr.msi file. During install it asked for a location of bookmarks (seemed off, like a new install) so the process was stopped. All FF profile files appeared to have been untouched based on their dates. So the following directories: \AppData\Local\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr \AppData\Roaming\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr where both copied to a secondary directory as a safety precaution. Install was restarted and it appears to have again installed a new version with no bookmarks, extensions or password DB carried forward from the previous install, which is not what I wanted.

Can this be corrected, by moving the copied profile back in.

Thanks, Brian

All of the sudden can't use Hotmail through Firefox I have tried clearing cache, making sure clocks are correct etc.

Hi

I cannot reactivate spell check as I type, with English dictionary and the thick box ticked. Previously I could not get rid of spell check in my 2nd language (Turkish) but as I have managed, now I cannot restore spell check in English.

Can anyone help please?

Should I delete and reinstall Firefox? If I do will I lose my bookmarks?

Thanks in adance to all.

My Firefox tabs crash repeatedly even when I tried opening them in Troubleshoot mode. When I play videos in the browser, there's this stuttering, buzzing noise while the sound lags, too. Usually it's tabs playing YouTube videos that crash, but I've also had tabs crash when I try to open completely unrelated websites. I've disabled hardware acceleration, repeatedly cleared my cache, and even tweaked some of my GPU throttling settings, but nothing seems to help.

bold text''''bold text' In Settings under Startup, I have check to open all my previous tabs, but when I am shutting down, Firefox wants to close all my tabs before shutting down. If Firefox closes all my tabs on shutdown, then those tabs will not be there next time I start up .... how can I keep my tabs when I shutdown and have them next time I start up

these shortcuts appear on my firefox home page are so annoying here is my setting , i toggle off all shortcuts related to history or sponsored shortcuts but they still pop up each time , i want to disable this feature i need only my selected shortcuts appear on home page what can i do ?

I've noticed in the last few days that I'm periodically losing keyboard character input on sites following the update to the latest version - 148.0 (64-bit) I thought it might be a power issue with my WiFi keyboard and swapped out the batteries but the issue has persisted and I haven't experienced it when testing in Edge and nor have I seen it when using Excel or Notepad++ which I use regularly. Keyboard input actually froze for 4-5 seconds in inputting the last sentence. The problem is presenting on a number of sites - e.g. Reddit and YouTube. I do use the Ublock Origin extension but have been doing so for quite some time. I did report an issue with the mid screen search bar a few days ago and believe that is to be corrected in the update of 10th March. Is this also a known issue with the update?

To open a Venmo account they send you to get.venmo.com and that page will not open despite my changing various security and privacy settings. Does anyone have any experience with this that can help. I'm using Windows 11 (upgraded from Windows 10) and I've noticed that some -- only a few -- websites still think I'm using Windows 10 but I don't think that is the problem.

I updated Firefox last week. A few days after, I discovered that when I signed into Firefox, I couldn't find my bookmarks or extensions that I'd had on it before. I tried the "Import bookmarks" menu, but it only gave me option to import from Microsoft.

Then, I saw two firefox icons on startup menu. When I hit a faded-out one, I got into Firefox and did see my old bookmarks and extensions. When I clicked a fully colored icon, I got into Firefox but couldn't see my old bookmarks and extensions.

I saw firefox listed twice on my "uninstall" menu. I uninstalled the later one. Now, there's only the fully colored firefox icon on my startup menu, but when I click it, I still don't see my old bookmarks or extensions.

Trying to log in to my account a few minutes ago to get help, I was told the password I was using didn't work, so I came up with a new one. When I logged in after that, I got a message saying my old data might not be available.

Is there any way i can get my old bookmarks and extensions back?
