Forum der Gemeinschaft Firefox

For the past few weeks, Firefox has started crashing when logging into various websites. I've updated Firefox, cleared cookies etc, reinstalled Firefox, opened it in Troubleshooting mode, updated my OS, disabled extensions... everything I can think of. After some sleuthing, it seems to only happen when trying to log into a website. Doesn't happen on every site, which is weird.

This is so frustrating, please help!

How do I prevent Firefox from re-opening my last session upon reboot, for example after my laptop dies or I shutdown without closing browser windows? I never never ever want Firefox to restore pages at any time for any reason.

Background: I use firefox for work, and I keep 7 separate firefox windows open to the sites I use to do my job. Because it's a pain opening them every time, I created a shell script (I'm using linux mint 21.1 by the way) to do it. I just double click a desktop icon to launch my shell script and all of my windows open in the order I like them to be in.

Unfortunately, if my laptop battery dies or if I just am in a hurry and I log out without closing everything, then the next time I log in and launch my script, it opens my first firefox window, which then decides to open ALL 7 of the windows that were killed when my laptop shut down, and then my script opens the remaining 6 windows it is supposed to open, for a total of 14 browser windows now open, and I have to close half of them.

What I tried: I googled around and the only thing I could find was the browser.sessionstore.resume_session_once settting, which appears to have no effect whatsoever when I restart (my test was to set this flag to false, open 7 browser windows, restart my machine without closing the browser windows, and then launch my script and the result was 14 browsers open instead of 7).

Version: I'm using Mozilla Firefox for Linux Mint (mint-001 - 1.0) with a Firefox version number of 111.0.

Firefox will not play videos from any site, including YouTube, Twitter plays in home screen but does not play in full screen mode, FoxNews or any site. I hear audio but there is no video. Firefox automatically updated Friday May 12 2023 and I don't know if that update had a glitch. I tried reinstalling firefox and it still didn't work. I cleared all history, cookies, cache, etc and still does not work.

please help, thanks

FF keeps replacing

http://mysite.domain.net:3344 with httpS://mysite.domain.net:3344

whatever I try to fix this behavior. Thing is that I own this server and there ever was't any SSL implemented. I mean this - never.

Other browsers (Chromium, Chrome, Opera) don't take such a forcing action, website opens like a charm. Why FF thinks it knows better which URL I really want to open?

I already googled _a lot_ in order to find solution, but no one worked.

Setup: Debian 11 Mate no proxy and no separate "internet security" stuff on laptop (other browsers with default settings confirm that) FF 102.11.0 ESR 64 no addons (all switched off)

already tried: browser.urlbar.autoFill false browser.cache.check_doc_frequency 1 network.stricttransportsecurity.preloadlist false browser.fixup.fallback-to-https false dom.security.https_first false

What else I could do to stop this madness? Thank you in advance for any help

I been having problems with firefox using up most of my cpu while browsing some websites and it doesn't even load as fast as before. This has been happening for a few days now. Prior to this, firefox was fine and loading pretty quick, but these last few days have been painful.

Thinking that was a small bug, i restarted my computer. Before opening the firefox again, I opened up task manager to check how much resources will the browser be using. Before that usage would be normal and not even close to high, but opening firefox and waiting a few seconds to let the home window appear, the task manager showed that it was using all of it still.

I browsed some other help questions on this website and disabled "Use recommended performance settings", because that was one of the solutions on one of the relevant questions. But even that didn't do reduce resource usage either. Is there any way to fix this or will I have to suck it up and suffer with slow loading?

Last Tuesday, Win 11 AND Firefox both updated on the same day, Firefox to 113.0.1. Ever since, my Firefox has experienced SIGNIFICANT lag time loading even the most basic of websites. It feels like Netscape 1.0 slow (yes, I'm that old). I've disabled 2/3ds of my addons to see if that would help and it hasn't. I don't know if it's an issue with the Win 11 update (KB5026372), with Firefox or some combination of both, but any help in addressing this issue would be greatly appreciated.

I am writing to you because the subject is driving me crazy and I don't know what to do anymore.

TL;DR; version?

The same laptop, with the same firefox (113.0.1 snap) at work works fine... and at home it has an exhasperating lag.

Any ideas?

It happens to me with all the computers at home (with ubuntu, linux mint...) but (and here comes what kills me) if I browse with Chromium, everything flies.

I've tried by wifi against an access point that acts as a repeater, direct against the router and wired to the router and the result is always the same: Firefox slow as the bad guy's horse... and Chrome light as a cloud.

I have disabled all plugins, browsed in anonymous mode, reset firefox... and no way... every time it loads a page it takes 5 to 20 seconds of blank page.

I am a firefox user since its tender beginnings, but this lag is going to give me an ulcer and I am militant, but health comes first.

Thanks in advance for your help.

Hi. When opening the Microsoft Website (answers.microsoft.com) i experience some memory leaks. See photo for details.

Someone knows why?

Video playing on firefox on my second monitor appears overexposed, as in, lights are extremely light and darks are extremely dark. I am not sure when this issue began.

I know it is not a calibration issue with my monitor because all other content looks as it normally does. I also know it is specifically an issue with firefox and not web video in general because if I open the same videos on chrome they look as expected. This only happens on my second monitor, if I drag the window to my laptop monitor, it looks normal again.

My current setup is an acer Nitro 5 laptop (i5-10300H, RTX 3050 laptop with game-ready drivers) hooked up to a samsung monitor (I belive 32" odyssey g5? I am not sure) through HDMI.

I've updated my graphics drivers, to no avail. I am going to try reverting the latest update on firefox, though I am unsure if it is related at all, I will update the thread if it corrects the issue. I don't really know what else to try if it fails, I appreciate any suggestions.

Other than the problem being firefox dependant, I suppose it could have to do with a firefox-GPU interaction, as my laptop's integrated monitor is driven by the CPU graphics while the external monitor is driven by the GPU. I don't know how to address this or if it's even possible.

After upgrading one machine from Fx 110.0.1 to Fx 112.0.1 (as per usual with "major" upgrades with the full install file) I noticed very high CPU usage when closing Fx, and it took quite some time to settle. I upgraded it to 112.0.2 via Help-About, but saw the same issue.

That is, starting Fx, opening a "private browsing window" and visit some site, say a search engine, then closing the private window and finally the first Fx window. (At the time I also see some spikes in CPU usage from the firewall software etc.)

Since I can’t have it like this, computer almost stalling for 30 sec, after closing Fx, and to see if there would be any update later to solve this issue, I uninstalled Fx 112.0.2 (I have complete backups of Fx profiles), and, just as a test, reinstalled Fx using the prior version of setup that I had, Fx 110.0.

Of course this meant a clean profile, not what any user wants to see (missing bookmarks is almost minor compared to all settings, incl. in add-ons, gathered over time. So I used the profile manager to change to my previously used default profile. After a restart I was greeted with a prompt that this couldn’t be done (since it may corrupt bookmarks(?) etc.) and I was left with the only options to abort (cancel) or create a new profile. Oh, great. I had not even used the newer ver. (Fx 112) to change or create anything, but I assume Mozilla could have something between the different versions.

So, I uninstalled Fx 110.0 (and of course in the process of creating a new profile/resetting settings it had reverted to "download updates in background", and I had to change that setting back, and stopped what was pending, during my tests trying to move it to my old profile). I installed Fx again, using the setup file for 112.0.1 and did a direct upgrade to 112.0.2, and pointed it to my old default profile, which had been used with 110.0.1 and during the first upgrade to 112.0.1.

Fx is working with my profile again, but it takes a very long time to close and (perhaps together with other software) consumes a lot of CPU, almost stalling the PC. During one such situation this morning I got two prompts for XULRunner "Could not determine any profile running in background task mode!" Never seen before. (I noticed that there now is a new folder in Roaming\Mozilla\Firefox\ called "Background Tasks Profiles".

Any help would be very much appreciated.

Keeps freezing. Keep getting "not responding" message. Typically I can have several tabs open on two screens but now after using Firefox for a while I start having issues. Really just want my favorite browser back.

I have been using Firefox for a very, VERY long time and until recently, loved it.

I have a few newer issues now:

1). If I am NOT on the internet using Firefox (Which is for internet use), why is it still running? This slows my system down while I am working with graphics programs. It should do an update check when I use it on the net (As a non-invasive background process) and not interfere with my work.

2). When I am online playing my game (Wizard 101), IF I have Firefox running in the background, I get lots, I mean LOTS of lag time and freezing screens. If I don't activate Firefox, then there is no lag or freezing screens.

Before you say I need to check my computer; sorry but THAT is NOT the problem. I have been using the same computer and the ONLY change is the "5 Million" tiny updates of Firefox.

So how do I fix these issues...or do I dump Firefox (And all things Mozilla) and find another browser program? Is it wrong to expect better from you guys??

My firefox is presenting some malfunction on many features that are not working as they should. I tried to updated to it the last version to solve. It did not work. So I tried to restore it. which should work as I dont think its problems has to do with cookies or saved personal info. It did not work as well. So here some of the problems:

1- My firefox's home page is suppose to show my most visted sites. But it shows only empty/blank space. (image ) 2- I cant add any extension to my toolbar. They simply dont appear when I try to edit it. 3- I cant remove/edit any favorites (changes are not applied). 4- Some extension are just not working. for no reason. Betterttv for example. (Tried to reinstall, reset permission. ). they were working normally before. 5- autofill are not working. Does not show the options.

All this does not make any sense to me. As I've tried to solve restoring the firefox. Only cookies, passwords and personal info should have being kept and I dont think they are the cause of all this. I dont wanna to fully clean reinstall it as there are many logins, passwords and other info saved that I dont even remember. In additon it does not make any sense to me at all.

Since `monospace` means something diffrent on every device, and I need consistency between clients I use `Roboto Mono` on my Website as ASCII-Art font. For some reason Firefox on Windows cannot render the font properly (view image). What can i do to fix this? The problem presists across my desktop and Laptop. See for yourself https://nx2.site/my-ascii-art (I cannot guarantee this is always up + In the future it's hopefully fixed?)

When I use FF, I find that it is much slower than say Chrome. For instance, when I start to type an email in FF nothing happens. 5 seconds later I double click on the empty space and only then does it start typing (very annoying!). I have discovered that FF is using more mB than any other application on my computer, always: ie, today I have 1 research article open in FF and nothing else and it is using 770mB (as per my device manager). In Chrome I have my gmail open, as well as 4 research articles and it is using 650mB. Additionally I am using LibreOffice right now with 5 open/active documents and creating a powerpoint presentation in Impress, and even that is only using 720mB. Why is FF using so much? And this explains why for months that I see things taking just a bit longer to process when using gmail in FF. Thank you for your replies-

No matter where I try to go on the net, aside from the search engines, I get the same Secure Connection Failed error, and trying again does nothing. I've been using Edge, Chrome, and Brave to get to sites, and only come back occasionally to see if Firefox is working again. I even tried a fresh install, and reboot...still isn't working. My anti-virus is Vipre. I don't use any others. Why, after years of using Firefox, is it that suddenly it's useless?

Just sent a note, and got a response...but...you suggested this article...This article may help. https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect

Well, it’s nice that they have something mentioning it…but I’m not seeing any indication of a way to fix it…just a description. I already KNOW what it looks like. Like this: Secure Connection Failed

An error occurred during a connection to www.bing.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Being as it’s EVERY stinking site, I’m not much up for trying to inform ALL the website owners…as I doubt that it’s their fault. I just want to be able to use the browser as I have for years. So far, this doesn’t solve my problem. Thanks, Ken

Hello,
