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 ?

Upon upgrading to v140.0 on macOS Sonoma 14.3 (23D56), YouTube no longer renders.

All add-ons (ad-blockers, development tools, accessibility tools, etc.) were removed and still the same non-rendering as of this evening June 24, 2025.

I recently updated to the latest Firefox. Now my bookmarks sidebar is black on black and I can't see what is listed on my favorites. I changed to a lighter theme but the sidebar is still very black. What happened? I am afraid to mess with it much because the last time I lost all of my bookmarks.

Thanks

PS I tried to send a copy of the problem but I just couldn't get it to load.

Several weeks ago Firefox worked normally for me. I left for most of the day and when I got home Firefox no longer worked at all. Everything on my home page was gone and when I typed in websites - such as my e-mail program or Facebook, nothing ever came up. I'm not super browser savvy, but I opened the menu and under help was "trouble shooting mode". I didn't know what that was but figured nothing much more could go wrong with Firefox, so I chose that. I had to rebuild the websites I had in a row on the middle of the page. I didn't lose bookmarks, but everything else was different. So I left it that way.

Earlier today, Firefox wanted me to do another update. I thought maybe by agreeing to that, things might return to normal. Noooooooo. It's no better whatever. Now I don't know how to get out of troubleshooting mode to know if anything will work normally again.

I am seriously considering switching browsers, but I have a LOT of stuff bookmarked and that would be very intensive to build all those book marks in another browser.

Subject: OCSP Must-Staple Behavior Observations in Firefox (Including iOS Platform)

Dear Firefox Team,

We have been conducting tests involving certificates with the OCSP Must-Staple extension and would like to share several observations regarding Firefox’s behavior across different platforms:

General Compliance with Must-Staple: On most platforms, Firefox correctly enforces the Must-Staple extension. That is, if a certificate includes the Must-Staple flag and the web server fails to provide a stapled OCSP response, the connection is appropriately terminated.

Unexpected Behavior on iOS: However, we have observed that Firefox on iOS does not appear to enforce this requirement consistently. Even when the server does not provide a stapled OCSP response, the browser still establishes the TLS connection. We are unsure whether this is due to platform limitations or an implementation inconsistency.

Redundant OCSP Requests Despite Stapling: Additionally, we found that Firefox still initiates an OCSP request even when a valid stapled response has already been provided by the server. This behavior not only degrades performance but may also introduce privacy concerns, it contrary to the original privacy and efficiency goals of OCSP Stapling.

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.

Each time a video call comes in, the message on messenger, says Video calling is not supported on this browser. I've gone to the browser settings and cannot find anything that would change this. Help.

Hello to those of you reading this,

Over the last five or so days, my Firefox has been acting in a wholly unpredictable way. Every time I launch Firefox, the inspect element tab will open and close itself repeatedly for about 3-10 seconds, stop for a bit, and then start again. CPU usage by Firefox skyrockets whenever the glitch occurs.

I have tried Troubleshoot mode, I have tried a clean install, I have tried to refresh Firefox, all to no avail. This doesn't seem to have anything to do with a Firefox update, as the last update to my Firefox was well over a week prior to the start of this issue.

I am running several extensions: uMatrix uBlock DuckDuckGo Privacy Essentials DecentralEyes PrivacyBadger BetterTTV Facebook Container Firefox Multi-Account Containers TTV Ad-block Wikipedia Context Menu Search Redirect AMP to HTML

However, none of these seem to be the cause of this issue as it persists in Troubleshoot mode and after a Firefox Refresh.

The only reasonable lead I have regarding this issue is that the browser console spams the error messages as can be seen in the image attached to this post. A recurring element is "server0.conn0.watcher2.process16". I'm afraid I know only enough about coding to understand that this is probably the root of the issue, but am completely lost on how to fix it.

Another tidbit of information, whose relevance I doubt but am including nonetheless, is that I recently transferred my C:/ drive from an SSD to an NVMe. I'm wondering if perhaps the application is trying to call on a process stored on the other drive. I find this unlikely, as similarly to the point on the Firefox version this only started occurring a week or two after I transferred the drive over.

Any assistance on this matter would be greatly appreciated!

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.
