I'm afraid I cannot continue using Firefox, after the last change, since I can no longer keep my tabs open after closing a session, as I specified in the settings: "Open previous windows and tabs." Can someone help?

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

For some months now when I click on a video that is on a news website, such as The Guardian or The BBC for example, the video screen goes black and nothing happens. Any suggestions?

Firefox 137.0.2 (64-bit)

I cannot load Firefox anymore. When I download the program for a reinstall, it only completes about 60% of the install before stopping. Is Google or Microsoft behind this??

Thanks!

So, I had an issue updating Firefox where it went into a loop... twice, and ended up re-downloading the Installer both times to force the update onto Firefox. Eventually, when it happened again a while after I restarted my computer, I managed to get it updated normally (after a tiny bit of prodding), without the need to re-download the Installer. But now, I have two additional copies of the Installer on my computer. What should I do? Should I delete the two extra Installer files, or should I not?

Numerous sites, most recently Etsy, will not give me access. The message is always this or some variation: "We detected unusual activity from your device or network. Reasons may include: Rapid taps or clicks. JavaScript disabled or not working. Automated (bot) activity on your network (IP 71.217.57.171) Use of developer or inspection tools."

This happens even if I disable Ublock Origin. The only other extensions I have are 1Password, Zoom and Undo close tab. How do I fix this? The problem does not exist if I use a different browser. It is VERY frustrating!

when attempting to move Firefox bookmarks to my new computer, I click import data within the Firefox page. The computer asks me to select the file. I have no idea where the bookmarks reside and cannot find a file. What is the procedure to get this done?

Is there anyway to force actual mozilla pages to be displayed in a dark mode instead of the blinding white background that hurts my eyes to view ? Thanks, David

If I use the close window shortcut (ctrl+shift+w) in Firefox it fails to close the window and treats every action I try to take as if the shift and ctrl keys were held down. For example, clicking on a tab will select it as if I were trying to move it as a group, rather than switching to it. Or, pressing only the T key will reopen closed tabs as if I had pressed ctrl+shift+T. This behavior will persist in Firefox until I close out of it completely and reopen. This does not occur when any other application is focused and ctrl+shift+w is pressed, and the effects are isolated to Firefox only when it does occur. Due to this, I do not believe that it is a hardware issue, eg. my keys just getting stuck. I haven't seen anything online that even vaguely resembles this issue. Any solution would be appreciated, even if it is disabling the ctrl+shift+w shortcut, as I keep pressing it out of habit and needing to close and reopen all of my tabs.

I have an Office 365 account through work and I'm using Copilot frequently. In Firefox I have a pinned tab for Copilot.

In recent weeks I've run into issues where the Copilot page stays essentially blank, i.e. the message field to enter text does no longer appear. The Office Toolbar still appears and when I switch to other Office365 sites like OneDrive and Home they work just fine. The problem only exists with the Copilot page. Refreshing the page does not solve the problem.

I found a temporary work-around by clocking on the lock-button in the address bar and selecting "Clear cookies and site data...". After doing this and refreshing the page it works fine again, but only for a while (like maybe the rest of the day). I don't know exactly what makes it break, but it seems like I have to apply the work-around on a daily basis almost.

Additional Info: I've been using this setup for at least a year and the problem only appeared in the last few weeks. If I open Copilot in either Chrome or Edge I don't have this problem (but I also don't want to use Chrome or Edge).

As the first screen capture shows (sorry it's in spanish), my PDF documents tend to not print on the full page, but rather only on the top left corner of it, i've already fiddled with the scaling and fit to page, i have cleared the printer settings from mozilla, still the same, ive gone into the about:config menu and changed paper_height, paper_width, shrink_to_fit, and scaling nothing works. The document prints fine on Edge (screenshot 2), no problems with fit, and what's even crazier is that some PDF files work just fine (Screenshot 3). Honestly i have no clue what else to do.

My computer downloads your updates over and over again, tying up my computer--none of the downloads ever loads This problem is can only be fixed by pull the plug restarts as these downloads will not stop until I do this

When I open a website in Firefox, the page opens OK but there Wikipedia website also opens in the background. The icon appears on the top row to the left of the name of the website I opened. When I close Firefox, the Wikipedia site opens and I have to close that too. Every time. What is going on? How can I get rid of it? Thanks. Windows 11.

Have downloaded the Foxfire browser onto a new desktop and I've signed into my account. I need to see the bookmarks on the homepage as I did on the first desktop. I can see them all, and well organized, in the "backstage", when I click on manage bookmarks. Can you help me get them on the home page?

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

I have two Firefox tabs open on my browser. Task manager shows 35 tabs using 897 MB of memory. How do I make this stop? And why are so many tabs running? I have cleared cache, cookies, etc.
