Firefox Community Forum

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?

It looks an update occurred but now my bookmarks Column has a white background with white type. I can't read anything there because its all the same color how do I change the background to black?

Saying "you can turn off the AI" is NOT enough, Mozilla. Nothing is ever "turned off" unless it's completely removed. This is Microsoft's playbook BS; "but you can turn it off", but for some reason the system is always using a metric ton of memory, lagging and whatnot. You, of all companies, should know this and be better than that. Nothing good is ever force-installed and impossible to remove. Unless you all make it installed completely separately so people like me, who are a significant part, if not most of your user base, can not install it, nothing short of a full renunciation of the CEO will suffice to make we trust you again.

"Internet for People, not profit" is seeming more and more like blatant false advertising every day.

Starting for last few updates (on the last month) each time I hold my mouse click button for a few seconds on any page I am greeted with this popup: (see attached)

Main question: How do i disable this popup?

Second, what is the feature even about? why is it a feature? and what is the point of it?

About: Firefox 146.0.1 (64-bit) - FF for Arch linux

I recovered my account using a backup code and set a new password. Two-step authentication is enabled but I don’t have the linked TOTP app. The settings UI does not allow disabling 2FA and does not offer backup code input. I still have unused 10-character backup recovery codes. Please advise.

I have never ever had a problem getting into my bank account until this evening.

Says it is insecure.

How can this happen? I really need to get into my account!

When I play YouTube videos in Firefox, the video stutters and drops frames, even when set to 480p. The audio continues to play normally. This issue does not happen in Chrome on the same laptop.

The problem started about a week ago. I’m using Firefox on Windows 11. Restarting Firefox did not resolve the issue. I’ve attached screenshots for reference.

When I try to access a function of my banks website I get the message: Authorization has been denied for this request

Late last year this occurred when using FireFox but not Chome or Edge. I have contacted my bank and was told I need to add an exception to the Manage Exceptions list. I did that and I was able to access that function of the site. Now the error is occurring again. This time I figured out what the URL was that needed be added. All other functions of the site work fine without these exceptions.

My question is: what are the security ramifications of this and what do I tell my bank so they fix this? Does this make their site less or more secure? Is it necessary to fix this?

Beim Herunterladen von Dateien wird mir immer angezeigt "Originaldatei heruntergeladen. API Schlüssel ungültig. Lizenz überprüfen. Die heruntergeladene Datei finde ich aber nirgendwo. Was muss ich machen?

When I choose to bookmark a website, I am no longer offered a chance to save to where I want it saved.

FF 146.0.1. Windows 10 pro

So, now I have to bookmark a page, and open the bookmark menu again to EDIT the bookmark to move it. This is Horrible. I have to do this eachj time I bookmark a page. I am veriy organized and have dozens of bookmark folder, some with folders within folders... etc.

Onliy children need to be treated this way.

I have searched the settings and find nothing. I am not using any add-on that has anything to do with bookmark. I do not use the bookmark toolbars or other bookmark interfaces. Just the file/edit... menu "bookmarks" option.,

Has this ability been removed?
