I have not been able to access my on line banking for three days now. I ran a diagnostic and everything was fine, no issues so why cant I connect to the banking server. Please help.

Recently (Jun 2025) When Firefox closes, an empty taskbar icon for Firefox remains. When click on it, it does not bring up anything. Nothing in the Task Manager to suggest that a copy of Firefox is still running.

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 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.

Cleared history etc. and the system will not open up the link I need to see my mothers blood culture results? Her is the link to the website https://patient.labcorp.com/landing

I have sugarcrm running via firefox. I show a phone icon for click to call next to phone numbers but click does not initiate the call. I have to highlight the phone, right click and send it to the dialer.

Is this a settings issue?

I saw my same issue described in an archived thread "Several users have reported connection issues with Google sites including YouTube. This has been linked to the "zero round trip resumption" feature. That is intended to speed up website connections, but there seems to be some kind of compatibility issue. Currently, there is only a hidden way to disable this and see whether it helps".

I tried the method given (going to about:config and turning security.tls.enable_0rtt_data to false) but it did not work.

I tried uninstalling and reinstalling, but I accidentally dragged the Firefox in the installer directly onto my dock (on Mac) and that Firefox was working perfectly fine. But I noticed there was "Firefox" drive running on my system. To fix it, I realized I had to drag the Firefox in the installer into my applications folder and run that Firefox. So I did so, and ejected the Firefox drive.

Using the new Firefox that was actually installed in my Applications, I am now stuck with the same problem of Google sites not being accessible.

I am sitting in hospital with a weird problem. The connection is open and thus not secure. I have successfully connected my 2 android devices, however my Windows Asus laptop is being barred by firefox. I only run firefox. It is a dead end because firefox refuses to allow me to access the net at all. So now I have to get my wife to go and download chrome and see whether that will work. Why can I not override as u understand the risks I also use Norton 360 with its VPN.

on the game 'my little farmies' by upjer, when I go to fullscreen, a blue haze covers the entire area making it difficult to discern colours. I have cleared cookies and reloaded the game, switched the pc off and on again. nothing makes it go away. does anyone have any ideas. i have asked upjers but they say it is a firefox problem. many thanks for any forthcoming suggestions.

How do I resolve this issue

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

I was in C-Panel looking to delete emails as the serve is full but wanted to see the emails before I delete them. The 38000 or so of emails had downloaded and I began the process of selecting and deleting when I got the message that this page is not redirecting properly. was never a problem in the past but is now why?????? and how do I resolve as I cannot received anymore emails until i clerar out the server?

Hi,

I use firefox nightly as my everyday driver for WEB. So far I was very satisfied with the performance and mostly with youtube videos and hardware decoding. I use a Nvidia 1060 (GP106) which supports VP09/AVC1/H265 decoding.

The problem started only recently after some updates of the Firefox when I noticed that VP09 isn't hardware accelerated anymore. They way I test is using the Windows 11 task manager/Performance/GPU/Video decode.

At the same time, the stable Firefox has no issues with VP09 HW decoding. The same is valid for any other browser I tested. So the problem is isolated to the nightly.

I downloaded and ran mozregression GUI which indeed showed me that some nightly version before the VP09 worked just fine. I tested using the dates option of the tool.

This is the push_log URL from my test.

Thanks in advance for your help

I have downloaded Duolingo on my Windows 11 laptop. When I try to run it, it says that it can not open it because it can't find Microsoft Edge. This is the latest version of the app. I can't find anywhere to change the Duolingo default browser. I have Firefox set as MY default browser in windows settings. I also have AVG Secure Browser installed on my laptop but seldom use it. I donot have MS Edge installed on any of my computers. Can anyone help me find a solution to this problem? What other information do you need?

My FF browser freezes, suddenly closes all tabs, expands fonts, etc etc All else in my system is normal. Should I just use the default MS Edge and be done with it?
