Firefox Support Forum

H, I'm using Firefox browser on my HP Chromebook but whenever I try to open my site on it. It is not opening properly like site's layouts does not show properly. What could be reason of it, site's code or browser issue?

In the last month Firefox using google search simply refuses to search, this is becoming annoying to the point where I will start using other browsers. Is there a fix for this?

My yahoo mail keeps closing when I am on firefox which is the browser I use all the time. I have to keep reopening it many time in a day. I am on a pc with windows 10

I cannot login to my Easyjet account using Mozila Firefox, i keep getting an error code, when i use another Browser like Brave i have no problems.I am thinking of deleting Firefox browser

In About:Config there are several settings for "smoothScroll.msdPhysics", which is disabled by default. Can someone here explain for what situations this set of preferences is intended to be used? I've been unable to find only very sketchy documentation for it, and I have looked a lot.

1. Is its purpose only for touch screens, or does it also have benefits for normal desktops & laptops?

2. Does it function independently of whether or not smooth scrolling is enabled in About:Preferences?

3. There are three About:Config settings for msdPhysics springs (motionBeginSpringConstant, regularSpringConstant, and slowdownSpringConstant). What effects do each of these have as the mouse is moved or the mouse wheel is rolled or clicked? And how do their settings work (e.g. time?, lines?, pixels?)?

On my computer, I run Mageia Cauldron with a GNOME environment. After a recent update of my system, both Firefox and Thunderbird have stopped working. They crash constantly when I try to launch either of them. In both cases, when I try to launch them from the command line, I get the following message: ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. Segmentation fault (core dumped)

For basic info, my system is: OS: Linux Mageia Cauldron Environment: GNOME Shell 43.1 Display server: X11 Kernel: 6.1.8-desktop-1.mga9 x86_64 Firefox: 102.7.0esr Thunderbird: 102.6.1

Looking around, it seems to be a bug with Firefox and Thunderbird, but besides waiting for a new update that might fix itself, I wonder if there is something I can do to make them work now.

Thank you.

I do a lot of autoscrolling, initiated by clicking and releasing the mouse wheel and controlled by moving the mouse away from me or toward me.

A particular problem for me is that ending the autoscroll cleanly often fails. I try end to end the scroll by clicking the mouse wheel again. Sometimes this succeeds, but often it doesn't and I get scrolled very far beyond where I wanted to stop (after making repeated wheel clicks and/or left mouse button clicks). Sometimes, totally out of control.

So, two questions:

1. What is Mozilla's intended way for the user to terminate an autoscroll event?

2. Can it be that the above problem is also related to keyboard lag (keystrokes often delayed by 1-2 seconds or don't ever make the screen) which I have been experiencing for some time? Maybe some mouse clicks are getting lost too, or are being delayed. I see in the forum and elsewhere online that a lot of FireFox users have had keyboard lag problems, in posts from many years back to the present, with few successful fixes. What is the best way for me to fix this? -- or is it a bug that needs attention?

I'm using Ubuntu 22.04.1/Wayland and FireFox Snap for Ubuntu 109.0 and I have two monitor bigger and smaller. After some time of using Firefox it's hang or something like that. When it happens I can normally open pages and use firefox except I can't move tab, resize window and when I move firefox from one monitor to second then it fit to half of screen (when move from smaller monitor to bigger) or window is behind monitor (when move FF from bigger monitor to smaller, you can see on screenshot what I mean). When I close FF and open everything works fine.

Why does the Firefox window collapse when it sees a typo? Specifically, typing 'te' for 'the' causes the window to collapse. I see this mostly on Facebook, but it apparently isn't their shortcoming.

How can I Fix this?

yahoo mail does not work, but does on Chrome. Also works on Firefox "private." I'm using Firefox 109.0. Yahoo Mail worked until a couple of days ago, but is unresponsive now. What to do?

I either need to get it fixed right away, or move to Chrome as my default browser. Please help.

I am running the latest Firefox on Mac OS Ventura and too often webpage loading slows to an agonising crawl. I can’t figure out what’s causing it. The system is not overloaded and the Firefox task manage also mostly shows idle tasks. I have no clue how to debug this issue.

Any help would be appreciated.

Hello everyone, I was here recently since nothing in Firefox wanted to load, but I fixed that by using old sessionstore.jsonlz4 so I guess that session was corrupted.

New problem: Everyday when I start my PC and Firefox it keeps crashing over and over until I use an old working sessionstore file again. So it seems that everytime Firefox tries to save my current session with nothing changed/ different from the backup it corrupts it and I have to use the old backup again - which obviously sucks since no matter what I open/ do today it will be "deleted" again tomorrow.

The only "interesting" thing the crash report shows is MozCrashReason: Failed to load critical module "resource://gre/modules/WebNavigation.jsm" but I will share the troubleshooting information below if that helps.

My only idea left is to save the most important tabs and wipe everything else off my Firefox to see if that helps - but if it doesnt then I have to restore my old session yet again and all progress is lost again no matter what I do.

Any ideas are appreciated especially since I didnt change anything relevant about my system or Firefox in recent times so I have no Idea where all of these problems come from all of a sudden.

After Firefox’s latest update (109.0 - 64-bit) I am experiencing several bugs.

I’ve narrowed it down to two things:

• Context and dropdown menus do not appear, yet they are present (if I click where they would be the intended behavior happens). This happens for both the menu bar and the toolbar, as well as when doing right click in any website.

• I cannot move tabs along the tab bar.

No extension is causing this since I have disabled all of them.

Is some else experiencing these or similar issues?

If these are not common problems, does anyone know what could be causing them and how to solve them?

Thanks in advance!

When I try to scroll, by rolling or clicking the mouse, there is a 2-second delay before scrolling starts. I am also getting a very awkward keyboard delay (for many but not every keystroke). Scrolling and keyboard use are normal in other programs.

I have tried with hardware acceleration both on and off. I have over 8gb of free memory, CPU at a low percentage used, and a low commit level.

I am a long-time FireFox user. I have been using my installed extensions for years, and have no newly installed programs on the computer.

When I click on firefox (once) to open it (internet connection good), nothing happens for ages then it comes up with the attached error message. I have to reload and sometimes it opens two or three windows and freezes. I have cleared caches, streamlined my laptop and checked for malicious software - no result. Please help thanks

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.

Firefox keeps attempting to access a web site with an unwanted application. The site is mv.outbrain.com and my virus software keeps asking to block the site. The popup is now becoming a nuisance how do I stop it or delete the reference to it
