After change the network connection to cable, or to a different Wi-Fi network, Firefox will lose connection and will be unable to access any website unless its is restated, closing all Firefox windows.

The problem happens when:

1. I have the Firefox opened, I disconnect from wife A, Firefox lost connection, then I connect to Wi-Fi B, all other browsers can connect, but Firefox does not. (if Wi-Fi A and B are from different router)

2. A start the computer disconnected, I open the Firefox, I connect to internet, any other browser that was previously opened can connect, but Firefox does not.

OS: openSUSE Tumbleweed 20210912 Firefox version (91.0.2. It occurs in the last two years, it is so annoying)

The Find bar used to have an X at the far left that I could click to close it. It no longer does. I looked up if there's a hotkey to close it, and it's supposed to be Esc, which is doing nothing.

The bar also appears to have the search box and option tickboxes all grayed out indicating unusable; they're not actually unusable, it's just the appearance that's wrong, but it shouldn't look like that.

Hi guys. I have Windows PC machine running for several years now. No new program updates or installs recently, no restarts. And then yesterday, suddenly Firefox started to crash all youtube tabs. Not even videos itself, but also www.youtube.com crashes. Any idea how could i find out, what the hell is going on? Microsoft edge is working fine with youtube. I have tried troubleshoot mode, same. Windows 10.

What can possibly cause this? Thank you.

Beginning 3 days ago, for no reason I know of, Firefox has become sluggish and active windows frequently report that they are "not responding": the cursor will spin, character entry is impossible, scrolling can't be invoked, and even clicks on other open tabs are ignored. (As an example, it has required more than 5 minutes to enter this text so far, even though I am now running in Safe Mode.)

Memory and system utilization usage is unchanged from earlier views under Task Manager (FF with many windows/tabs open may take on average 1524MB out of 32GB on the machine, and perhaps 5% of the cores, more or less).

I have opened no new or never-used-before tabs in this period, and have also closed a handful of them to see whether that produced any difference in these symptoms. (It did not.)

As mentioned I am operating in Safe Mode and these errors persist. In any case my only add-on is Adblock Plus. I upgraded FF to v87.0 last night on the chance that the version change would make a difference, with negative results.

At the moment Troubleshooting info indicates that I have "9/9" Multiprocess Windows, and I will try to include an image from that page.

These hangs occur in all windows, so the fundamental problem appears to be in a more basic process.

No other function on the pc is misbehaving in any way, but FF itself is now nearly unusable.

The only temporary cure I have found is to restart FF, after which there are no occurrences of non-responsive windows for a period of only 3 minutes to 15 minutes (during which FF memory and cpu utilization are generally constant).

Reinstalling FireFox or engaging in further profile updates or about:config changes are all well in scope for this problem determination. The one restriction here is that I cannot afford to lose my current windows/tab entries.

Many thanks in advance for all assistance, questions, and suggestions!

Before I close the Firefox browser i go to Settings>Clear Data> Cookies & Site Data>Cached Web Content. I clear all and the Cached Web Content is lowered to 45kb. History is deleted. There is nothing in Manage Data or Manage Exceptions. The computer is turned off. A day later the computer is turned on and Cached Web Content is 2Mb.

Windows Defender anti-virus malware scan and full scan have been run. The computer is up to date, Win 10 Home, version 21H1, OS build 19043.1237.

Any idea what is causing Cached Web Content to grow from 45kb to 2 Mb when the computer is turned off?

Is it possible to disable automatic "word search"? every time i'm on a page and hit some letter key mozila opens the automatic "search keyword" without my wanting it. I want to open the "search keyword" only when I press crtl + f and never, never in automatic. it also hinders to play browser games, I can not play games because any key that I press the mozila opens the "search word"

Hello there!

I noticed that pip play mode in Firefox is different to other browsers. In other browsers, once the pip window is opened, it remains open until user explicitly closes it. User is able to navigate away from the page containing the video and it will still remain open. In Firefox, once user navigates away from the video source, the pip window will close.

I'm working on a website which will include some tutorial windows on the home page. It would be useful for the user to be able to open the pip window and then navigate around the site to try out features described in the tutorial video. This is possible with other browsers, unfortunately on Firefox, once the user navigates away (even knowing that it's a SPA) and the video element is removed from the DOM, the browser will not keep the video stream open anymore.

Are there any plans to change this behaviour to match other browsers? Maybe there's an extra attribute that I could add to the video tag to preserve the pip window between navigation events? Maybe there's a temp hack (i.e. keeping the video tag in the DOM but hidden - for SPAs) or will I need to develop a custom media player to achieve this?

I installed Thunderbird 91.1.1 and am trying to add my gmail account. I provide my email and password, new window opens with login prompt at Google. After logging in, I am prompted to Allow access by Thunderbird. I click Allow and I am redirected to the attached screen. I am thus unable to use Thunderbird...

I have an image map that works fine with Chrome. However it fails in Firefox and Edge. It behaves as if the image is bigger, and therefore all mappings are incorrect. Why would different browsers look at the same image, and behave differently?

I updated TB to 78.12 two days ago and have not been able to start it. I restarted my PC a few times and tried Safe Mode for both Windows 10 starting and TB to no avail. Installing V78.11 solved the problem instantly. Everything is back to normal now. I wonder if anyone else has experienced the same.

BTW, I cannot find a button to click to ask a question. I had to search the Internet and find this link to ask this question: https://support.mozilla.org/en-US/questions/new/thunderbird/form Could anyone shed some light on this?

Hello,

It is suspected that latest version of Firefox version 78.11.0esr (64-bit) is causing operathing systems to crash. I have not seen it on Windows platform as I am not using it. Platforms I am using are OSX and XUbuntu. The error occurs lingering on a site for a very long time. First it starts getting screen graphic errors like, some pixels are not being updated correctly. Then after a while screen starts to flicker, in a massive state, like the graphic processor is broken. In some cases with command key strokes one is able to kill Firefox, screen is back to normal and one can continue working. Facebook is the site that most commonly is causing error, but there are also other sites.

My email program has not worked since 9/11/2021 when the new update was installed. I am unable to download new messages and it resets my connection to my email server on earthlink.net. I've tried every suggestion I've found online to fix it to no avail. This computer is on Windows 7. I was going to try backing out the update since it was working fine before the update but the Thunderbird uninstall wizard doesn't give me the option of just uninstalling the latest update - it indicates it will uninstall the entire program. Any ideas for fixing would be greatly appreciated.

My MacBook Air is alerting a Trojan spyware alert with an error code in my Firefox browser. I ran malwarebytes and it did not detect any issues. I also opened safari and that ran without an error message so apple tech said to contact Firefox for support. Should I just delete and re-install Firefox or is this a more compromising issue?

Hello,

what can i do when i get a message "Sorry. We just need to do one small thing to keep going." with <Restart Firefox> or "Gah. Your tab just crashed." all the time i open firefox? A restart with Add-Ons disabled does not help. I send the troubleshooting information from Help/Troubleshooting information. As one can see Firefox does not seem to produce crash reports either.

Kind regards Atomino Zweitausend
