I have followed the steps in the "Prevent Firefox from starting automatically" article: https://support.mozilla.org/en-US/kb/firefox-starts-automatically-when-i-restart-window

But Firefox keeps starting automatically when I restart my computer. Attached is an image of how the settings are now.

What should I do? This is a bit annoying. I don't use Firefox as my main browser but I work as a customer success manager for an online platform and always need to do some tests on Firefox, but I don't want it to start automatically when I turn on my computer.

I'll for instructions.

Thank you

The problem is that even after I've tinkered with the about:config settings to prevent Firefox from restoring my previous session after a crash, it just won't listen! The changes I make in about:config don't seem to save, and every time Firefox crashes, it happily reloads my old tabs and windows.

Your assistance would be greatly appreciated!

Hello!

I recently got a new computer with Windows 11 freshly installed. I downloaded Firefox, went to take a screenshot, and the usual shortcut of Ctrl + Shift + S does not work. I can right click and Take a Screenshot, and I can use other Ctrl + Shift shortcuts, like Ctrl + Shift + T to reopen closed tabs. The only one that doesn't work is screenshots. I can also put Screenshots in my top row Toolbar and use it, just not the keyboard shortcut.

I refreshed Firefox, uninstalled and reinstalled Firefox, as well as checked the about:config extensions.screenshots.disabled preference. It has been set to false, so I have set it to true and false again hoping it would "reset" it but nothing. Thank you!

I have Firefox installed on two PCs. I see the option to add "Recommended by Pocket" under Settings/Home, but on the other one I don't. Screen shots of both are attached. I have completely uninstalled, cleaned up all Firefox files and re-installed Firefox multiple times on the PC where I don't see the Pocket option but nothing changes. Also gone into about:config and tried making changes from there. I want the Pocket recommendations to show on the Firefox Home page for both PCs.

Thanks

For a few weeks now, Firefox has been often freezing a webpage for 5-10 seconds during browsing. It mostly happens when going back to the previous page, but also when clicking a link or doing a google search. For those 10 seconds, you can't do anything on the page; no clicking other links or selecting text.

I've already tried: - troubleshoot mode; it still happens when all extensions are turned off - turning on/off hardware acceleration - creating new places databes - updating to the newest version

What can i do to fix this?

Hello Firefox Community,

I've been a long-time fan of Firefox's bookmarks management system, but over the past year, I've encountered a persistent issue that's affecting my productivity. I regularly use the bookmark bar and organize my bookmarks into folders. However, any changes I make don't seem to stick and get reset after a period of time. This is especially frustrating as I heavily rely on bookmarks to keep my browsing organized. Problem Details

Here's what typically happens:

1. I add a bookmark to a specific folder or position, either in the general list of bookmarks or on the bookmark toolbar.
2. Sometime later, that bookmark leaves its designated position and moves to the bottom of the unsorted list of bookmarks.

Devices and Operating Systems

• MacBook M1 2020 running macOS Monterey
• Dell Alienware 17 r5 running Windows 10

Both devices have the latest version of Firefox installed, and I use Firefox Sync to keep my bookmarks and settings consistent across these devices. Suspicion

I suspect that this issue occurs when I make a change to bookmarks on one computer and then open Firefox on the other computer. The bookmarks seem to reset, possibly due to some issue with Firefox Sync.

Looking forward to hearing your thoughts and possible solutions!

Kind regards,

Hola. Mi ordenador tiene Debian 12. Utilizo Firefox 118, instalado a través de Flatpak. El problema que tengo en algunas páginas es que veo las fuentes pixeladas y la impresión es muy defectuosa, hasta el punto de no entender lo que aparece escrito. Esto sólo pasa en algunas páginas.

Si descargo directamente Firefox desde la página de Mozilla y abro la paǵina con una configuración limpia del navegador, las fuentes se ven correctamente; sin embargo, si sincronizo los datos de usuario, instalándose los datos, extensiones y demás las fuentes en determinadas páginas se ven mal.

Desactivé las extensiones pero el problema no se resuelve. Desde una instalación limpia de Firefox instalé una a una las extensiones y complementos, pero no logré reproducir el problema. Borré incluso la caché del navegador, pero nada. Y también sincronicé los datos de usuario en una instalación de Firefox en Fedora, pero el resultado es también negativo.

Alguna idea?

Gracias.

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

This is my second email to you....

I just switched to Firefox from Chrome, because Chrome was crashing all the time.

All I want to do is sync my computer, laptop, phone and Ipad's reading list. I want to be able to see an article on one device, add to the reading list, and have it on all devices.

I'm logged in under the same name on all, and it says sync is on, but the reading lists are different.

Can someone help me? My phone number is [removed phone# from public support forum], email is [removed email from public].

Thank you!

Is spell-checking done locally on my computer, or is it done on the Mozilla website? I just found out that the Chrome and Edge browsers send my typed message to the home office, and that is where the spell-checking is done. Can I assume that this process is done locally on my own computer with Firefox?

I've been paranoid about security for many years, and every little bit of info I can add to my personal well-being lets me sleep that much better at night.

I am currently 82 years of age and have been using Firefox since it first became available, just because of its advertised security features. Quite happy with it and hope it stays on top of my needs.

And I have the same question regarding Thunderbird and its security properties.

Thank you.

Any ideas why I am seeing these strange rectangles on Google maps?

Confirmed not caused by an extension as I still see them in Private window and do not see them when using Brave.

They don't stay in the same geographical location when zooming in and out.

Hi! please help me lmao i'm not sure wtf is going on. I recently (as of a week ago) had to wipe my pc and reinstall windows 10 after a botched update. So i installed firefox on a practically new pc. thing is... when i turn it on, i get this baby in my taskbar (see image): right under the pinned firefox and thunderbird logo, i get a really scrungly OLD (and i mean OLD) firefox logo. clicking it opens nothing. hovering over it shows a preview of a blank window with a random string as title. clicking it only opens a second blank window with nothing in it. eventually when windows finishes starting up, it closes itself. i'm scared it might be a virus. help? how do i make it stop??

I'm running firefox 117.0.1 on windows 10 home single language 1903 (sorry if that's wrong, i dont know where to check otherwise)

I want to navigate on search results using the keyboard. I could use tab but it suggests all interactive elements such as news, images, books, videos, search settings and etc one by one. I want to press something and make active first result, then second. If such hotkeys are not provided, maybe there are any extensions with similar functionality?

I want to report that spyware named FindItPro which I, foolishly, downloaded. Well, it's a virus, right? But no antivirus can delete it completely. It comes back and you can't find the source. So, there should be some problem in your browser that allows it to live.

I'll send you a website where I got it. [link to suspected malware removed] BE CAREFUL. Virus will be downloaded along with Opera browser or something. I'll send this report also to some antivirus company. Yes, I was foolish, but I hope you will fix it.

I run a website that is custom built and we are seeing a potential issue in which the headers and header links are showing in the reader view of every page above the content for the page. But I'm also not sure if this is necessarily bad or might be affecting SEO.

Does anyone know whether this is detrimental to SEO, and if so, are there any suggestions on what might be causing this to happen in the code?

Hello! I have used Firefox on and off so I don't have a time frame of when this would have started exactly, but I have had some random completely black screens on both of my monitors dating back to at least 2-3 weeks ago that can only be fixed by powering down the entire PC. I've reinstalled my (NVIDIA) GPU drivers, rearranged display-port cables and just about anything before finally finding a fix, switching to edge. So far I've gone a week without black screening when with Firefox I'd get around 4 give or take a week (some days getting to 3 alone). I don't know what could cause it but I have noticed it only happens when first starting a video. Mostly YouTube but other video sites seem to have also caused it occasionally, I would just like to know what could be causing this, as I do prefer Firefox vastly and would like to switch back as soon as I can.

Will provide anything else as necessary!

Hi, I have been searching a way to change the Firefox new tab background image keeping its vanilla design. I found I could use a userContent.css file in this post from a few years ago: [https://support.mozilla.org/en-US/que.../1271362] I have followed the instructions step by step but it doesn't currently work.
