Firefox, as of less than an hour ago, is no longer saving tabs on close. This was also proceeded (After the first instance of this happening) by Firefox enabling the "Delete cookies and site data when Firefox is closed" setting (Privacy & Security -> Cookies and Site Data) all on its own (Also did this on my laptop a day or 2 ago). I have since uninstalled & reinstalled it almost 5x. Doesn't matter what settings I change. Doesn't matter if I'm logged in or not. It will not save them. Ever.

I have history set to not delete anything. I have the most obvious setting enabled (Startup -> Open previous windows and tabs). It still doesn't save them. Even after the reinstalls.

I have not changed my settings in over a month. The only difference between months ago, and now, is browser updates, and an extension I installed but didn't even have Enabled.

Including the issue with the browser not defaulting to the last folder that was downloaded into with the "Ask where to download" setting enabled. But that's an inconvenience. It's not making the browser virtually unusable like not having my tabs saved.

I changed my language from Arabic and back, and now I see a little line attached to my cursor within all web pages that I visit, that I believe was added as a result of my language change to Arabic and then back. I have attached screenshots of what a normal cursor looks like vs what my cursor in firefox looks like now. I have not had this happen before today when I have switched between languages in the past. It looks normal within the Firefox address bar, but not within text boxes within web pages.

My current language settings are set to US English, but I keep the others as alternates to switch back and forth between.

I updated yesterday to Windows 11. Following that update,I had a few difficulties getting Firefox up & running. It seems to be OK now except for the Firefox icon appearing twice on my taskbar when I switch on my computer. Is there an easy solution? I am not technically skilled. Thanks for any guidance.

I am constantly denied access to my online banking, my bank says, because I use Firefox, and that I wouldn't have this problem if I used Chrome - any possible truth to this? Any fix? thanks

Duck Duck Go search from the address bar suddenly does not work. All queries return a page with the search box and no results. Google search functions correctly. Additionally, the search function on Yahoo Finance no longer functions. Both of these websites and functions work on a mobile version of Firefox connected to the same wifi. At first I had no idea what was causing it but after using troubleshooting mode and turning on extensions one at a time it turns out that metamask was causing the error.

Ever since I updated last week, one website that I use will not work. Whenever I try to log in to the M&T Online Banking website, it blocks me and says "M&T Online Banking Is Temporarily Unavailable." The app works on my phone and I can log in through Chrome, it's only on Firefox that I'm getting this problem. I called M&T Bank and they confirmed that it's a problem with Firefox. Something is blocking me but I don't know what it is. I am not using a VPN or adblocker.

I can't get to my yahoo email account because they say I have an ad blocker. As far as I can tell there is no ad blocker on my computer. I've never added on and on the game I play ads come on all the time. I would love to find anything on where to even find where an ad blocker would be on my computer. I've searched add ons and extensions and apps and everything I can think of and no ad blocker. Please help

Dear,

I use a hotkey for the screen-capture program "Snagit". The hotkey is: CTRL-SHFT-P

However, it now seems that also the AI-search program "Perlexity" uses the same hotkey.

Where can I remove the shortkey for Perplexity?

Начиная где-то с 06.03.2025 возникла проблема, что не отображается YouTube-плеер на странице при запуске любого видео. Вместо этого белый фон. Есть расширения по блокировки рекламы. И есть нюанс. Сначала отключаю все блокировщики, страница YouTube обновляется, плеер появляется и всё работает. При запуске другого видео, плеер снова пропадает, появляется белый фон. Запускаю один из блокировщиков рекламы, страница обновляется, плеер снова запускается и работает без проблем.

It says Login failed, but I have successfully logged out and back into my firefox account.

I've been using the firefox pdf viewer for quite some time and it's worked quite well. Within the last few days though I've developed an issue.

When I open a pdf it opens correctly for just a brief second (standard text, white background, nothing unusual) and then switches to something like the attached image (black background/ text and such). I have not changed anything that I'm aware of, though I did just recently install a new firefox update (136.0 64-bit windows 11). I didn't notice any articles or comments about this particular issue here yet, so figured I'd ask for some help.

Anyone know how to resolve this? Or other things I should look into?

Thanks for your time, Derek

All of a sudden my Apple laptop Firefox is responding VERY slowly. It takes about 10 seconds from hitting enter to any screen response. I've tried it with and without my VPN on, and there's been no changes to my Avast security software (that I know of). I've reviewed the settings/preferences without any clue about what is happening and what I could do to minimize it. I've run a speed check which resulted in 287 down and 190 up, so it's definitely NT my network.

Not sure why, but Gmail is not loading, then Ebay shows gmail pic broken, and can't log into ebay either. I can log on bot via private window tho I have removed all ad-ons, uninstalled adblock, still no go, this happen with Some of the Firefox updates, but different sites. Thanks

I recently created a new Firefox account using my new gmail address. I still have an old Firefox account associated with an old gmail address that was compromised; I would like to delete the old Firefox account. When I try to sign in to the old Firefox account, I'm told I'll have to sign in using my "primary" account--presumably the new account. When I sign in to the new account, I only see an option to delete the new account, which I don't want to do, as I have Firefox Relay and passwords connected to it. How do I delete (only) the old Firefox account? Thanks.

When I display a statement from Tesco Bank it opens a new tab and says that I can download or print it from there but I can find no Download tab nor anywhere in the customisation options to add one.

Is anyone else having issues with some pages refusing to load over the last few days. My Gmail account and my Bank of America page became intermittent over the last few days and now simply refuse to load. Both readily load on my Android phone and also load on the computer in question with Microsoft Edge. Has there been an update I missed or any other issue with such pages suddenly becoming incompatible with Firefox?
