Diễn đàn hỗ trợ 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

I'm on the ESR and just updated from 112.0.2 to 113.0.1. I had text rather than icons displayed on my toolbar. Now the text has vanished and I can't find a way to get text OR icons back. I have a disabled extension Classic Theme Restorer installed, but I thought it was already disabled long ago. In the Customize Toolbar dialog, the unused icons are displayed with text labels. When I drag one to the toolbar, it turns invisible like all the rest.

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

Your browser is a bit unusual...

Try disabling ad blockers and other extensions, enabling javascript, using a different web browser or turning off your VPN.

Hi,

For years I have read directions to get my tabs back where is most logical for me, below the Bookmarks Toolbar. Now with this latest version of Firefox the workarounds I had before are not working.

To cut a long story short: I have made a Chrome folder under the Profile folder I have made CSS sheet with what looks like the commands I need. I have configured Firefox to read the userChrome.css sheet.

I have followed all the directions on this thread https://support.mozilla.org/en-US/questions/1375646 (most of which are repeated elsewhere) and it still doesn't work.

I am beyond frustrated - if anyone happens to know where I can go to request this as blinkin' option I would love to know.

Please could someone help me sort this out in the meantime though?

This is what is in the CSS sheet (which is in the correct place according to the above instructions - checked that already):

Thank you in advance.

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?

Title says it. Basically, I forgot my main password for Firefox. The only way really was to make a new password for my accounts. I knew I'd lose access to all my other passwords but that's life. I was able to disconnect and then reconnect with my new password on my Android application and log on to my accounts on another machine, but it's been impossible to log out and start fresh again on my main computer (MacBook Air). As per normal, whenever I open Firefox (I've deinstalled and reinstalled multiple times, as well as deleting cookies) I immediately get the pop-up box asking for my password. It does not accept the new password, which has worked on other connected machines. I figured the only way to get around this would be to log out of my account on my MacBook, but then the only way to do this is by using my password -- which this specific pop-up box will not accept. Is there a way around this?

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.

Hello,

My old PC crashed and I want to transfer my bookmarks from the old hard drive to my new PC running windows 11. I have unlocked hidden files, but when I ran drive:\Users\username\AppData\roaming\Mozilla\Firefox\Profiles nothing came up. I then ran places.sqlite and a list of places.sqlite appeared with some files having -wal &-shm after them?

I believe from reading here this is where my bookmarks are?

If so, how do I transfer them to my existing PC hard drive to use please? Many thanks Chris

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.

Just recently, in the past day or so, when I do a search in the search box, all the results get redirected to Bing instead of Google, that I have in my settings as default. I have checked my settings, I even removed Bing from the list, and I still only get Bing results. Even when I go to Google and use their search box on their domain, I get Bing results. I did a virus scan without finding any problems. I'm stumped and don't understand why this happened and nothing I do can detect uncovers why this is happening.

Really irritating when I have to spend my time fixing stuff that is lurking in cyberspace!

I bought your VPN. Does not install. Does it work with Microsoft Surface Pro X (ARM)? If not I need a refund. If it does, I need help installing it. Thank you for your time.

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.
