I returned a phone that I had for 2 weeks (the phone was a Motorola G Stylus 2024, if that's even relevant), and while I did a factory reset on the phone before returning it, I am worried that my Firefox account information is still accessible through the device.

One reason why I am worried is because, when looking at synced windows open, *everything* that I had open on there was open and accessible through my account. Another reason that I am worried is because I did not log out on the device before returning it to my local Best Buy.

It'd probably be impossible to track down the exact phone that I had, but can anything be done? Should I redo my log-in password for Firefox (or even all the sites that I used on that phone) or am I worried over nothing?

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

I recently ported from chrome to firefox about 3 days ago and was tryin to access the dropdown menus on this website https://www2.gov.bc.ca/gov/content/governments/government-id/bc-services-card/your-card/get-a-card

I realized it wasn't working so I turned off my adblocker (ublock origin), refreshed the site and still not working.

Also attempted to use troubleshoot mode and still does not work.

Cleared cache + cookies and used troubleshoot mode and nothing working still.

I lastly checked the website was working by opening the same link on chrome after all that and it works perfectly fine over there. Any ideas what could possibly be the issue?? I basically have a fresh install of firefox with no changed settings besides anything that might of been copied over from Chrome when firefox automatically asks you to migrate your stuff over, and used the troubleshoot mode + clearing cookies and cache

How in the heck do you increase the size of the UI font? I have a 1440P monitor and the TINY size of the UI font makes it nearly impossible to read the text on the menu buttons, I have lean forward and squint to read it because they are so damn small. I can't find anything in the settings to make the UI text larger. It is as if some dummy hard coded the UI font size so it's impossible for the average person to find out how to change it. It makes no sense whatsoever.

And please don't tell me to increase the zoom in the Windows settings, because that screws up EVERYTHING else...

Another thing that is driving me crazy is how do you set it so that scrolling with the mouse wheel is smooth and not jerky? When i scroll with the mouse wheel, instead of smoothly moving the page up or down, it JERKS a couple of lines at a time. This is the only browser that it does that in. I have smooth scrolling ON in the mouse settings on my computer but for some reason, only Firefox is doing this.

After exporting bookmarks.html from Ffox on old computer, importing it to Ffox on the new one, all good, except that bookmarks toolbar shows on the imported list but doesn't display as toolbar.

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

Hello Firefox Support,

I’m encountering a strange issue with Firefox. While playing YouTube videos at very low quality (144p) just to listen to music, my GPU usage spikes to 100%. This happens even when the video is not fullscreen and there’s minimal visual content.

System Info:

   Firefox Version: 140.0.2 (64-bit)

   Operating System: Windows 11 

   CPU: AMD Ryzen 7 8700F (no integrated GPU)

   GPU: AMD Radeon RX 7900 GRE

   GPU Driver Version: AMD Adrenalin 25.6.1 

The issue goes away when I disable hardware acceleration in Firefox settings, but I’d prefer to leave it enabled for better performance elsewhere.

Is this a known issue with AMD GPUs or is there something else I can try to reduce GPU usage during playback?

Thank you for your help.

idk when exactly this nonsense happen or with which update but thats outrageous.

why the hell it canceled in my setting the check mark at startup for opening previous tabs?! i haven't touched the settings in ages since i set them up so it had to be one of your stupid updates.

fortunatly chatgpt had a solution to bring all my tabs back otherwise i'd fucking rage out.

i'v been using firefox for ages but after this i was really thinking i should switch to something else.

The release notes for Firefox version 140.0.1 indicate the extension button can can now be removed from the toolbar.the noes say:

"Firefox Extensions: Customize your toolbar with the option to remove the extensions shortcut, giving you more control over your browser. When the button is hidden, you can access the extensions panel again at any time from the Firefox menu by clicking the Extensions menu item."

I still cannot drag the button down and out of sight by customising the toolbar.

Suggestions welcome.

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

I want to add a dedicated search bar next to the address bar. When I search how to do this, I read: To add a separate search bar in the Firefox browser, navigate to Settings > Search and then click on "Add search bar in toolbar". This will place a dedicated search bar next to the address bar. But when I search for "Add search bar in toolbar", I get a message there are no results in Settings. I have Windows 10 laptop.

I am using the FireFox PDF Editor to annotate a PDF, however, no method of me saving the document (whether that is save as, or save as PDF) will allow me to save any annotations on the document. If I try doing save as PDF, the preview shows up as blank sheets of paper, when I click "save as" it only saves one page of the 31 as BLANK. If I try doing normal save as, the saved file is un-annotated.

Please help... thanks

Guten Abend, bisher konnte ich wenn ich mit Firefox arbeite und etwas herunter geladen habe, den Bereich für alle Downloads anzeigen immer als Tab anzeigen lassen, auch ohne dafür ein Addon zu installieren. Nachdem ich Firefox nun auf einem anderen Computer neu installiert habe, kriege ich diesen Bereich nur noch als neues Fenster angezeigt, was ich als sehr störend empfinde. Kann mir jemand weiterhelfen, wie ich das wieder so einstellen kann, das die Downloads wieder als Tab werden? ich weiß leider nicht mehr wie ich dies damals umgestellt hatte.

The app sizes two adjacent images to the same height. Maybe there's a better approach?

This works, in that I see the original image displayed at the wrong size:

   //img.src = imgsrc.src;

This sizes the image but without the data (black square for toDataURL w/ image/jpeg) in FF, but not Chrome and Safari:

   var canvas = document.createElement( 'canvas' );
   canvas.width = width;
   canvas.height = avail_height;
   var context = canvas.getContext( '2d' );

   // Tried/failed: Fill white background for JPEG export
   //context.fillStyle = '#fff';
   //context.fillRect(0, 0, canvas.width, canvas.height);

   context.drawImage( imgsrc, 0, 0, canvas.width, canvas.height);
   context.lineWidth = 150; // ??

   img.src = canvas.toDataURL('image/jpeg', 0.92);
   img.onmousedown = disableDragging; // for FF
   img.style.opacity = "1.0"

The page is the view.html one gets to via Enter on phobrain.com.

Hello,

I'm facing an issue where my microphone does not work in Google Meet when using Firefox, even though I’ve granted all necessary permissions. This problem is specific to Firefox, as the microphone works perfectly fine in Google Chrome.

I prefer using Firefox because of its convenient screenshot features, but this microphone issue has caused major inconvenience during important meetings.

Kindly help me resolve this issue.

Thank you.

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

Hello, I think I may have asked about this in the past but cannot recall if I received an answer. Under Settings, I get the message "Your browser is being managed by your organization." This is my home computer and is not being managed by any organization. When I click for more information, it gives me a screen with the following information:

Policy Name Certificates

Policy Value ImportEnterpriseRoots

                         true

If I could get more information on this suspected error, or how to correct it, that would be great. Thanks!
