I want to move my whole folder and to backup and move it to a new PC. But it says when moving a file called activity-stream.discovery_stream I need a permission from myself.

Why do I continue to receive a message from Firefox after creating a New Profile?

Firefox This profile was last used with a newer version of this application. Please create a new profile. OK

A new profile PERSONAL #2 was created following the Steps to Create a New Firefox Profile.

What did I do wrong? how to correct, so that I stop receiving the error message?

I cannot get into my online accounts, as I have always done for years. After I select the site, the screen looks like it is working, but then a new empty window pops up: the tab says "citi 400 Bad Request" At the top of the empty screen it says: Bad Request. Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I usually watch videos on Firefox on Stan - https://www.stan.com.au/account/login - with no problem on Debian. Just wondering if this is a fault with Firefox on FreeBSD, so I know where to go looking for the problem. Other outlets have sub par performance, also, such as YouTube, where the video comes up but plays like it's operating at one frame/5 seconds, with no sound. Thanking you for any time and trouble.

I am using Windows 11 on both my desktop and laptop. I began using vertical tabs a ways back. On my desktop I am able to scroll through the active vertical tabs with the mouse. But, I am unable to scroll the vertical tabs on my laptop. I have compared the Firefox settings on both computers and have been unable to find any settings that are different which could be applicable.

Roughly one third of my bookmarks all changed to sites I have visited recently. They still have the same labels, but when I click on them, they just take me to some random site I've visited recently.

День добрый. Я с 2023 года не выходил с аккаунта. После переустановки системы, и установки новой версии браузера, синхронизация не подтягивает мои данные (закладки, пароли и тд). Данные очень важны, мне остро необходимо их вернуть.

Just made a new profile and wiped everything from my history following another issue which isn't strictly speaking resolved. I am unable to load image-dense websites with any consistency. Issues do not occur on other browsers. I receive similar errors on Twitch:

"Recent changes in how some corporate web sites react to FireFox such as not show the header menues and other function reduction in the last three weeks. YET Chrome and google still function like normal. Is this an attack on Linux supported browsers? " I contacted United Health Care (UHC) regarding their menu disappearance and treated it like error on my end until I discussed doing their recommend fixes and the only ones that worked are going to other Google or Micro-Soft supported browsers. FireFox was working fine until three weeks ago. What's up, is it FireFox or UHC?

I saved and closed a few tab groups about a month ago and now they're no where to be seen. Nothing is in the down arrow on the right and I don't see any groups searching through history. The text when I closed them said I could re-open them at any time. Where are they?
