Diễn đàn hỗ trợ Firefox

About two weeks ago, Firefox started randomly hanging and would stop responding. It wouldn't let me close the program and I always have to restart my system to resolve the problem. Sometimes it only takes a few minutes after restart before it hangs, other times it will be fine for hours.

I've tried multiple solutions I've found online, carefully following instructions: clearing cookies and cache, disabling all extensions, refreshing firefox, creating a new profile, deleting specific files within the Profiles folder, etc.

I've yet to make it more than four hours without the program hanging.

Any assistance or suggestions are greatly appreciated.

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.

This is a bit of an odd question, but I'm gutted. I have pretty severe OCD and AI tools have become very problematic for my reassurance seeking behaviors. I just got all of them blocked using tools like coldturkey and screen time. Now as of this update they're all in my firefox sidebar, and so far I see no way to block, only hide them (the trouble here is I know it's there, if I'm feeling a compulsion it's incredibly difficult not to follow through). Is there any iron clad way to block this? I hate how hard these things are being pushed!

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!

Firefox recently started "eating" my tabs: closing them without my permission. There are several tabs I want to keep open at all times, because I refer to them from time to time throughout the day, but Firefox closes them from time to time. I googled the issue and the AI directed me to two settings: browser.tabs.unloadOnLowMemory and browser.tabs.min_inactive_duration_before_unload. It suggested setting the first one to "false" and increasing the duration of the second, or setting it to "false." However, the setting will only accept numeric values.

Since I am not having low memory issues, I want Firefox to leave my tabs alone. Is there any way to actually do this? If not, it would be really nice if Firefox developers reversed this intrusive change.

Thank you, Terry

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.

So when I open some websites such as the RimWorld wiki ( https://rimworldwiki.com ), whenever i scroll my gpu for firefox launches straight to 100% and becomes extremely laggy. I have no idea what is causing this. My friends and other browsers run it completely fine. I have tried troubleshoot mode, gotten rid of all my extensions and themes, removed all cookies and cache and nothing works. My drivers are all updated, and I have truly just given up. If anyone has any solutions I would be much obliged.

Hi. I'm still new to Firefox and don't really know the settings very well. I recently switched over to using it and realized that when I use most drop down boxes the background of the drop down menu is black, but the text is white and the selection box (when you hover over the item) is also white. Making whatever I'm hovering over very hard to see. I'm wondering if I have a strange setting turned on or not?

Settings wise I have Firefox set to dark mode, not the auto. But when I use the auto it still happens. Trying it in safe mode it still happens. Iv tried to research this a little myself. And read something about the proton setting and turning that from true to false. But this also did not work.

Is there any way to fix this? I just need the text to be a different color or the selection box (when you hover over it) to be a different color.

Attached are two screenshots of what I'm seeing

I cannot sign into my att/yahoo email while using Firefox. After calling AT&T they told me to use Microsoft Edge which I told them I would not! When trying to sign in I receive the error message "It's not you, It's us" try again. It is my belief that att is trying to coerce me to change browsers so they can spy on me

Kind of a combination 'Browse/Download problem. This morning on rising, 07/11/25, Claude.ai's html artifacts quit loading on Firefox. Doesn't matter whether I'm on laptop Macbook Pro or iMac...or iPhone...but it loads in Safari and Google Chrome? Site is fine...document artifacts are fine...but html sits with spinning wheel?
