Hello.

I use Firefox on an computer with Ubuntu, (installed as snap) and have noticed that since the update to version 140, 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 closing 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 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.

Hello, I have just upgraded to windows 11. On firefox I used to be able to right mouse click on the firefox icon in the taskbar to select my saved saved (Pinned) websites. In the past with Windows 10 I right mouse clicked on the url of favorite websites then drag and drop on the firefox icon in the taskbar and that was it. On Windows 11 that no longer works. How do I pin my favorite websites to the firefox icon in the taskbar on Windows 11? I thank anyone for your help.

Hello! I had to change my laptop for work and there were very important settings, passwords, etc., which I successfully restored on new devices. I forgot my password and had to reset it via email, after which I can't sync. I don't have visited tabs or anything else. Please restore my account history. I was not aware of the data being cleared when resetting the password.

I lost all my bookmarks with the most recent update of Firefox. And now, it won't even let me bookmark anything. It just doesn't respond at all. I have an html of an older version of my bookmarks and was just going to re-populate my bookmarks, but that doesn't work. Plus, when I try and see my download history... nothing there either.

When assigning a URL to the mediaplayer object it started appending the current path to the URL. Did not do that in prior version. You can see it automatically puts the current browsing URL and then the URL that is assigned. So the file will not load. GET https://www.swingtechnologies.com/https://www.swingtechnologies.com/UploadVideos/clarkj@pobox.com/S200629_019 A.mp4 [HTTP/2 404 8ms]

allow audio and video is preset as the default, however, it is still muted. when you got to mute audio it won't play the video, and no audio/video seems to be working fine, I've followed all the guides, tried everywhere I'm aware of in firefox and nothing seems to work

I watch Rakuten Viki, and suddenly a recapcha box is popping up on the bottom right, blocking the full screen button.... so annoying,,,, how can i get rid of it/ THANKS

Hi I have mozilla running as primary for my imac and my 2007 macbook pro that is dying. I've just got a macbook air to replace the macbook.

The imac and macbook pro share th account and passwords just fine. I try to put the correct password into the air, it says incorrect password.

Fine. I do a whole 2 step authentication for resetting the password. Sign in on air. Now macbook pro is saying incorrect password. Fine. Put the same password in, it now says incorrect password.

Every time I change the password on the account, one of ht computers accepts it, the other does not.

I realy just need 2007 to work long enough to get the junk I need off it, and then it will be retired. Fine. But I cannot get the macs to all agree that the password for mozilla is the password-- even tho it's the correct password, says incorrect.

I haven't checked the imac, but knowing my luck it will now say i'm logged out cos incorrect password.

All I want is to sync the mozilla account for all three computers (before I reset this 2007 one and then recycle it).

Help would be appreciated for this luddite. thank you!

I have Sequoia 15.5 on a 2021 MacBook Pro and have always used FF as my browser. Now, I can't get it to do much more than open. Nothing new happened that I know about, except updates to "Malwarebytes" I have some computer knowledge but not a lot. TIA.

The Atlantic.com site says: as below, this was not the case in the past. Similarly with the NY Times I did not have this problem before I went on vacation on 10 June. Neither tech support can help. This problem does not occur if I use EDGE

I've been trying to play multiple videos at once, but when I pause one, it pauses all of them, and vice-versa. I'm not sure if this is a settings or config issue. I've tried disabling all extensions, and the issue persists. It's frustrating having the background music pause every time I have to pause a lecture to write some notes down.

I prefer to use Firefox with WordPress when coding. I use an important plugin that gives me SCSS fubctionality that used to work without issue in Firefox until recently. The problem is conflicting keyboard shortcuts, namely tab selection "command + option + up arrow", and "command + option + down arrow" (on a Mac). I would like to reassign them, or better yet, set them to "false" as i never use the feature. I have tried many suggestions online, and none are working. Any help solving this would be much appreciated. Thank you.

For neither of the two web pages below can I get Firefox to autofill a successfully stored username and password.

I've tried inputting the login information and answering yes when Firefox asks to save. I've also tried to manually enter the URLs and login information into the Firefox password manager.

I've also set up custom permissions for each site - allow popups, location, etc etc. And I've turned OFF Enhanced Tracking Protection entirely for both.

In ONE instance, I went to the page, and Firefox HAD entered username and password. But as soon as I logged in, the bank in question sent a 6 digit text in order to reach my account. That was successful, but upon attempting a later login, autofill was no longer working.

The websites are acting as one would hope with Safari - MacOS is offering to enter the password.
