Firefox Community Forum

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 ?

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 have 374 saved Passwords & User names in Firefox on my computer. Just bought a new PC and want to transfer the data to firefox or chrome on new unit. How can I do that? Is it possible to transfer the data?

thank you, Rena

Hi Mozilla Community,

I run a food-focused website that showcases restaurant menus, and I’m currently having trouble with one specific page—https://olive-garden-menu-with-prices.us/—which loads significantly slower in Firefox compared to other browsers like Chrome or Edge.

The page is mainly text and optimized images, and I’ve minimized scripts as much as possible. Still, Firefox seems to hang while rendering or takes a long time to fully display content. Could this be due to any specific Firefox rendering behavior, caching issues, or something I may be overlooking?

Any tips on how to debug or optimize page performance specifically for Firefox would be really appreciated. Thank you!

If I need to upload a file I click on the OPEN or BROWSE button in the website, Open File dialogue opens trying to list the location it is already looking at, and it hangs for over 30 seconds before listing files. This is windows 11, but it did it when i had windows 10 too. I dont know what to do.

Hi,

I don't come from an IT/Tech background so this has become a hassle for me. I have a "Old Firefox Data" file on the my desktop and that seems to have sub-folders with my bookmarks, sessions, logins, etc. How do I retrieve those to the new Firefox browser.

Thanks!

I downloaded the trust wallet extension, used a memoric phrase to import a wallet. It kept saying invalid memoric phrase, but after a about 30 minuets passed my wallet was emptied... so that was a hacked or bogus extension file.

Yesterday I got a prompt saying there was an update available for download. Today when restarting my laptop and opening Firefox ALL of my bookmarks are missing!!! My bookmark toolbar is also empty. Where did all of this important stuff go? Please help me restore this my information asap. I am freaking out!

Recently switched from Chrome and in Chrome I would open my "Other Bookmarks" folder and middle click a bunch of bookmarks which would open them up in a new tab without switching to that tab or closing the "Other bookmarks" folder.

Is there a way I can replicate this on Firefox? Because at the moment, middle clicking the bookmarks does nothing. This is not about the bookmarks bar at the top.

I used to use Firefox as my standard browser until this issue occurred some years ago. I can no longer add, edit, or see any bookmarks I previously had. When I start the browser, I'm met with an error message (see below), which then sends me to the site in the image below. The title roughly translates to: "The System for Bookmarks and Browser History is Non-Functional". I've tried following these steps in the past with no change regarding this issue, and I've had to switch back to Chrome. I've also tried uninstalling and reinstalling Firefox, but the issue persists.

Has anyone else encountered this?
