Firefox Community Forum

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

Hello.

I use Firefox on an computer with Ubuntu, (installed as snap) and have noticed that since the update to version 140 (specifically, version 140.0 canonical-002-1.0), closing a tab causes a noticeable delay : that is, upon any action that would close a tab (clicking on the cross, pressing CTRL+w, or middle clicking), there is a delay of about 200 to 300 ms before the tab is actually closed.

However, during this delay, the window still responds to inputs, leading to rather annoying situations. For example, during regular usage, I usually open a great number of tabs. When I am done with browsing, I close them, by repeatedly clicking the cross button on the tabs. It used to be that the tab under the cursor would immediately close, then the next tab would slide under the cursor, and I would click again to close that one, etc.

But now, when clicking the cross button, the tab is not closed, and when I click again after a small delay (because of muscle memory), the tab is still there. This cause the two single clicks to be treated as a single double-click, which for some reason puts the window in full-screen mode (but only with the snap version; I'm not sure what's going on here).

When using CTRL+w when closing tabs, the delay is still there, but the inputs are correctly handled. If I press CTRL+w three times at the usual rate, I can see the three key presses, then nothing happens for a few instants, then the three tabs close at the same time (i.e. the delay is from input to tab close, not from tab close to other tab close).

This behaviour is completely absent on Firefox (also version 140) on my windows computer.

This delay does not appear when creating tabs, and it does not occur either when closing the window or when closing the last tab in the window (leading to an amusing situation where shutting down Firefox is actually faster then closing a tab). These operation keep going at their previous speed, immeasurably fast to the human eye.

Navigation does not appear to be meaningfully slower than before the update, and the CPU/memory usage is very reasonable.

Curiously, this appears to be a fixed delay. Closing an empty tab takes the same time as closing a very busy one. Closing a tab when there are five takes the same time as closing a tab when there are thirty.

This issue makes browsing feel incredibly sluggish.

Is there a solution for this problem ?

Edit 1 : I have tried to run Firefox in troubleshoot mode, but there was no difference in behaviour. Edit 2 : Fixed typo. Edit 3 : Added exact version. I also tried to refresh Firefox, but the issue remained. Edit 4 : The problem is still present in version 140.0.1 canonical-002-1.0. Edit 5 : The problem is still present in version 140.0.2 canonical-002-1.0. Edit 6 : As of version 140.0.4 canonical-002-1.0, the problem seems to have been fixed. Thank you.

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!

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!

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

In the past, I would create new profiles in Firefox often on my macOS Macbook pro. I want to merge them all together (merge open tabs and their saved info, cookies, bookmarks, passwords, etc.) into the same profile.

I found this tool: https://github.com/james-cube/firefox-session-merger but I'm not sure if it will do everything I want to do.

Is this possible to do without using Firefox Sync?

Hello! I cannot edit our Weebly-hosted website. Firefox will not load the editor, apparently because of embedding issues.

I've tried a new tab, a new window, the private browser, and another browser, all with the same outcome, which leads me to believe that Firefox and Weebly need to have a discussion to fix this. I've also Weebly to the tracking exceptions, even though I don't think that's the issue here.

If, however, there is something I can do, please let me know.

Thank you for any help - I need to edit our website!
