I cannot sign into Vanguard Mutual funds after 20 years of doing so. I can sign in using EDGE. I have the latest version of Firefox. I have some Ghostery stuff. I have Windows 11.

Anyone encounter the same problem?

Bonjour, A chaque fois que j'essaie d'imprimer un PDF sur Firefox, il me sort des pages complètement noires sur une brother DCP. J'ouvre les mêmes PDF sur Edge et pas de problème pour les imprimer. Le problème vient bien de Firefox qui envoie n'importe quoi via pourtant le même driver qu'Edge. J'ai vidé mon toner de noir avec votre bug.

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

The installation on my win 11 laptop is doing some odd things (1 - recently lost all extra (unselected) windows on restart, even though set to restore all windows and tabs and 2- opening a new window creates an outdated duplicate of the window I already have open instead of just creating a new window with an empty tab??). So I thought I'd try refreshing it. Well, my "More troubleshooting" page does not have the "Refresh Firefox" button, only the "clear startup cache" appears along with option to run in troubleshooting mode. No Refresh option in teh same page in troubleshooting mode either. I am using the Microsoft Store MSIX installation. I am thinking about uninstalling that one and installing from a Mozilla download instead??

What would be the best way to clean up my installation state since the refresh is not available?

When using DuckDuckGo Search I cannot drag and drop the search URL into my Bookmarks. I can drag and drop a Google Chrome search URL into my Bookmarks as usual. Also, the correct URL is not shown for the search using DuckDuckGo. See attached screenshot.

Please resolve.

I have Bing as my homepage, but on one computer I have a very annoying problem. I click on the settings to turn off 'Show news and interests' and 'Show trending on Bing', but the next time I come back to the homepage these settings have turned themselves back on. What do I have to do to retain these settings?

Hi, I need help with an issue related to how my website https://forganica.com/ loads in Firefox. The site works fine on Chrome and mobile browsers, but in Firefox some elements are not rendering correctly and the layout shifts on scroll. Is there a recommended way to debug layout or CSS rendering issues specifically in Firefox? And is there any Firefox-specific setting or developer tool I should check to understand why my site behaves differently?

Good morning,

I have been using the Dashlane Password system on my desktop for several years and it works great with Firefox, however, Firefox was recently upgraded (automatically) to Firefox version 145. Now I can no longer access the Dashlane application which contains all of my passwords. What should I do to recover my Dashlane application?

I have just upgraded to version 145 and the title bar has disappeared Even though I have the Title Bar option checked in the customize firefox panel. If I uncheck the title bar option and then check the title bar option, the title bar will appear, but when I close firefox and then restart firefox the title bar is gone.

To sync a mobile device, the instructions say to open Firefox browser on mobile, from Menu go to Sign In, aim phone camera at QR code. The 3 lines at the screen bottom right (i'm assuming this is a menu but printing an icon labelled "menu" is less cryptic) offers no sign in opportunity.

I run the current version of Firefox on a Dell Inspiron 15 3530 laptop under Windows 11 Pro, I've found two webpages that I can't scroll--there's no scrollbar on the page, and the arrow keys don't work. On other pages, there's no problem. but I simply can't scroll thes pages. What's going on here?

Good Morning, Please how can I add or take out in firefox the icon shortcuts with most visited sites that I use, Also firefox is adding by itself shortcuts to my opening page and I don't want to have more than 6 or 7 or firefox suggestions. Thank you for your help

Hello. The browser will start fine and run for most of the day. I haven't made any known changes to the PC. At some point the browser will crash for all tabs and all windows. Any attempt to refresh goes to the screen as seen in the attached image. The "Restore This Tab" button does not work. I have to close all Firefox windows. Then the browser will work again.

I'm using an Alien computer. Windows 11. Everything is up to date. Firefox version 145.0.2 (64-bit)

Thank you.

Is there an application to get rid of 'Old Firefox Data' folder? I tried to remove it once on another machine and i lost all internet connection (needed a full Windows restore) so very nervous about this.

Yesterday, 50% of my bookmarks were deleted and now I can't bookmark anything. I tried to restore my bookmarks to several previous dates, but I received the following message each time:

Unable to process the backup file.

I tried to bookmark different websites and no bookmarks are saved now. I updated to the latest Firefox today and no change.

I am currently using Windows 11 and Firefox 145.0.2 on my desktop computer. Firefox is set as my default browser. Since the latest Firefox upgrade, the "Downsize/Minimize/Exit" toolbar does not appear upon opening and the only way I can close the program is to go to File<Exit, but I still have no way to downsize to share my screen with other applications. I sometimes have to open and close the program a couple of times before the Minimize toolbar appears. I already tried Firefox "Refresh" but the issue is still happening. </p>
