Firefox 技術支援討論區

I often have multiple tabs running simultaneously in Firefox, and would like to adjust the volume on some of the individual tabs to be less intrusive.

Chrome has a way of doing this, but I cannot find the same setting in Firefox.

Hej everyone!

My PC has crashed to a degree that it won't start anymore, but with many opened tabs in firefox on it. I have a new PC now and took the harddrive out the old pc to recover my files and would also like to recover the firefox tabs which should be somewhere in the firefox user data.

Can anyone tell me how to proceed, what to copy?

Thanks a lot! Regards, Niko

tab context menu is not visible to read but if i move the mouse pointer it is visible; how to set it permanently visible and readable; it was visible and readable earlier but suddenly for the past one month it is not visible and readable; I need your help in this regard as I am not proficient with computer operations

An old question but seems like the about:config parameters have changed recently. the following don't exist anymore : toolkit.cosmeticAnimations.enabled ui.prefersReducedMotion

I've searched with other keywords but couldn't find the new one.

Firefox browser has become more and more unstable. When opening a new tab where it be opening a link in a new tab or a new tab and going to a website. It just does not go anywhere and then eventually all my other tabs stop working as well. I am at the point of moving to a different browser, what can we do to fix this?

Hello! My Firefox version is 91.11.0esr Several months ago Firefox starts behave this way. It's much more convenient when speaker button always appears on tab. It's absolutely incomprehensible why developers did it with Firefox. Who likes to waste time searching for noisy tab. I wish it work like before.

As the title says, ctrl+tab simply doesn't do anything anymore for me. All the other hotkeys (ctrl+t, ctrl+1, etc.) are working normally. I haven't changed any settings or installed any extensions lately. It still doesn't work if I restart into Troubleshoot mode.

I really can't figure out what happened.

Since I updated to Firefox 102.0.1 (64 bit) I have a problem. Firefox automatically close the first tab. This happens in two different situations:

1) I close Firefox. When I re-open it, the first tab is missing. It doesn't happen all the times. But at least 60%. (My Firefox is set to show the tabs of the last time when I open it).

2) I'm downloading some file from my email or other place. Sometimes it goes fine. Other times the tab I'm using suddenly closes.

This problem has never happened with any other Firefox version.

I use double monitors for work and I have my firefox on my 2nd monitor when I click a hyperlink the popup opens on the main monitor. How do I fix it to open on the 2nd monitor so I don't have to drag it over every time.

Had Firefox 9x or so installed on my mac and then updated to 101. Now tabs go to sleep, unloads. So videos paused and the timer reset, webmail have to login again and again. If saving websites temporary in tabs now can change after article/sites get updated.

Setting "browser.tabs.unloadOnLowMemory" to false do not work. Tabs still go to sleep with the "ZZZZ". Have tried to restart Firefox and reboot computer.

Tried to install older version of Firefox but then it complain about compatibility with the old "settings files", so have to make a clean install then... Possible to force this? Change what version the "settings files" are so older version of firefox dont complain?

I use the Feedbro-Addon, which creates an own tab. Its url is: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html

If I use it as a normal tab (instead of a pinned tab) ... it survives a Firefox restart. But if I use it as a pinned tab (which I want) ... it disappears after a Firefox restart.

I suppose it has to do with it being an addon-page instead of a "normal" page.

Is there a way to make it stay permanently pinned?

I just restarted Firefox and, much to my distress, the tabs are now as they were on May 27th (I know this because that is the date in one of the tabs). This means some tabs are open that I closed in the last seven weeks, and all the tabs I opened and kept open in the last seven weeks are gone (in this case all my research). The information is there in history but it would take me hours to reopen all the hundreds of research tabs I opened in the last weeks and then close the ones I already closed as I no longer need them.

Why has it done this? How do I keep it from doing this again? And is there a way to force it to open with the tabs I had open just a few hours ago?

Thank you!

While using Firefox all of my non-pinned tabs disappeared suddenly. The History -> Recently Closed Tabs item in the menu was greyed out. How can I get these tabs back? I have not closed the browser yet.

After the latest update to 102 I'm not getting a full screen tab preview when I hover over the tab preview thumbnail. Is there a fix, or is this yet another "improvement"? jaco 7/14/22

I used to be able to move my tabs around in Firefox, but now they've become "fixed" in position when I open them. I verified in the Help Files that one can "Change the order of tabs To move a tab to a different position on the tab strip, just drag it there using your mouse", but now I can't seem to do that. What do I need to do to restore ability to move the tabs around? Using Windows 10, , and recently in the last week Firefox updated itself while the laptop was "sleep"ing to Firefox Version 102.0.1 (64-bit). Thank you. ~ SR

I am on a windows 10 computer and for some reason when I click on one of my tabs they sometimes delete themselves despite me not clicking on the close button and on top of that when I open a new tab it deletes itself as well.
