I launch Firefox from a shortcut in the QuickLaunch bar. I need to double-click that to get a response. But then TWO instances of Firefox open, and I have to close one - which seems a waste of time and effort over and over and over. My system is x32Win10ProV22H2. How to get just one instance ?

Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-55-a5277f.png

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

Support Firefox to be able to use different tab view modes on different windows! For example, two Firefox windows on different monitors, in my situation below:

- One on a 1920*1080 hori screen, with vertical tab sidebar disabled - One on a 1080*1920 vert screen, with vertical tab sidebar enabled for this window only in this case.

It brings much more convenience, at least for situations just like mine :)

Greetings...

I have noticed in my Windows 10 Task Manager that Firefox has an excessive number of processes active when Firefox is started with only one empty tab. By excessive, I found eleven (11) Firefox processes today, and I have yet to even start using Firefox.

I have only a simple Theme enabled and no Extensions enabled in my Firefox. I have tried deselection of the "Use recommended performance settings" but this does not appear to help. Disablement of my Theme increased the number of Firefox processes.

Any idea how I can significantly reduce the number of Firefox processes that appear in my Task Manager when I use Firefox? I really prefer to use Firefox as my go-to web browser, but lately it has become troublesome at times.

Thank you in advance for your help with the above problem. Take care...

What the title says. Firefox just isn't playing any sound whatsoever.

Troubleshooting:

  • Volume mixer indicates that Firefox is using my speakers, along with all other apps. When playing a YouTube video, the green bar is not bouncing. However, all other programs that play sound do so successfully and their green bars are bouncing (see attachment).
  • Other web browsers play sound successfully.
  • Restarting Firefox and my computer did not help.
  • Switching the default sound device and changing back did not help.
  • Changing to headphones made no change.
  • Tabs are not muted.
  • Autoplay settings in about:preferences showed that audio and video were disabled, however changing this setting to allow video and audio, then restarting both Firefox and the computer did not fix the problem. I have no idea how that setting was even changed to begin with. O_o
  • Started Firefox in troubleshooting mode; still no sound.
  • Started Firefox in a different profile; still no sound.
  • Started Firefox in private mode; still no sound.
  • Tried ending the audiodg.exe process in task manager and restarted; still no sound.
  • Double checked media.autoplay.blocking_policy, was set to 0.
  • Double checked media.block-autoplay-until-in-foreground -- changed from true to false, restarted Firefox; still no sound.
  • Disabled hardware acceleration; still no sound.
  • Refreshed Firefox; still no sound.
  • Complete uninstall, including the usage of BCUninstaller to uninstall "leftovers". Reinstalled. Still no sound.

I have Apollo installed on my computer and I've reached out to them before for similar issues, but the dev was insistent that Apollo does not cause sound issues. I'm somewhat sceptical, but they're not being helpful at all so I thought I'd ask here, and disclose usage of Apollo so that all bases are covered.

Thank you for your time.

Recently, after the newest Windows 11 update, Twitch hasn't been loading correctly, the tab looks as if it finished loading, but the page gets stuck in endless loading, no other site has this problem, and it happens even opening links to Twitch channels directly. I've added and screenshot of the problem.

I'd love some help or at least know if this is a problem on Twitches end or not. Thanks.

I'm an older pensioner, I've no wish to learn more tech stuff which is unconnected with my question. For years I've been concerned at the invasive nature of Microsoft products and so want to get rid of Win10/11 and install another OS. (I have hundreds of documents in Wordpad (.rtf) and MS are just cancelling it!) It'll probably be Linux based. So, simply I want to take my existing Firefox browser with passwords etc., to my new OS. I asked this question in Firefox and it seems Mozilla can't get over the fact that I don't want change my iOS browser to a synched up Firefox. I don't want my phone connected to my pc. Perhaps that is difficult for today's tech whizz-kids to understand but I can't help that. I'm not really technical but have had Firefox for nearly 30 years, so can anyone tell me if it's possible to copy my Firefox into a folder somewhere perhaps, and reconstitute it to work with my new OS? It certainly used to be possible. Thanks.

I wanted to completely disable TLS 1.3 when using Firefox, so I set security.tls.version.max to 3 (which corresponds to TLS 1.2). That worked up until I got version 140.0.4 installed - now it completely ignores this setting no matter what I set. I tried using cloudflare-ech.com website for test and it confirms that my browser uses TLS 1.3 with ECH. I also tried modifying security.tls.version.fallback-limit to 0 and security.tls.version.min to 0 to get a possible range of TLS 1.0-1.2, but it still uses TLS 1.3.

hallo zusammen wo finde ich in firefox eine funktion, die mir die zuletzt angesehen und geöffneten tabs wieder herstellt?😐

in den einstellungen ist "Vorherige Fenster und tabs öffnen" angehakt.

es kommt aber wiederholt nach updates dazu, dass die letzten fenster und tabs nicht wieder geöffnet werden, sondern nur 1 tab mit der festgelegten startseite.🤷‍♂

muss ich mich damit abfinden, dass die letzten tabs hin und wieder im nirwana verschwinden? oder gibt es auch dafür einen tipp für laien?🙏
