Firefox Community Forum

I tried several things, but nothing helped so far. I did an offline-scan with Windows Defender, I opened FF in troubleshoot mode, cleared cache etc. I got the following crash-ID:

bp-7a77a8ad-7637-4fba-bd20-9e4730251209

Maybe someone here is able to help me. Thanks in advance.

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?

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.

Since the latest Firefox update, the color of the letters appears black on a gray background, making them invisible. How can I change the colors of the bookmarks sidebar? Thanks in advance.

(If any relevance, I'm on Macos 12 Monterey) 'Installation and updates' seemed the nearest topic due to the 'update' part of it, since this seems to only have been happening since this version, or I have simply not noticed due to not having needed to know. But if you look at my two screenshots, you will see the issue. There simply is no About Firefox on my firefox. Neither directly listed on the menu, nor as part of the 'help' sub menu.

Is there, for the sake of learning, a simple fix, so that I donlt have to uninstall/re-install? or an 'about config' type fix? Screenshot 1 shows the menu Screenshot 2 shows help sub-menu As you can see, absolutely no About Firefox

And, only potential issue may be, as you'll see from the share data upload is that I've a lot of tabs open, as I've got a lot to get through toniught, and tomorrow. So, maybe, t=though doubtfully, it is because it isn't handling the tabs and this caused a menu entry to be missing? Surely not likely.

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 Governor of Poker site gives me an error message when I try to log in with Firefox:

Your browser does not support graphics API "WebGL 2" which is required for this content.

Not a problem with Google, Edge or other browsers.

Graphics Acceleration is turned on.

Any other thoughts?

How can I get all Firefox settings as a simple table? I am sure that is how they are kept by the program, somewhere outside the Firefox UI. Are they kept in the System Registry? It would sure make troubleshooting & continuity easier when moving to new devices/CPUs.

SEVERAL SITES THAT I USE ARE NOT LOADING CORRECTLY WITH MY CURRENT AD BLOCKER. WHEN I DISABLE THE AD BLOCKER THE SITES LOAD NORMALLY. I AM NOW USING A DIFFERENT BROWSER UNTIL A SOLUTION IS FOUND.

how do i completely stop updates? or at least until i restart the browser, not the browser making me restart it. i have it set to "Check for updates but let you choose to install them", but its not really a choice if im forced to press the button to continue browsing...

it happens twice a day that firefox prevents me browsing and makes me wait 30 seconds for it to update after clicking the "restart firefox and update" button. very frustrating.

Since updating Firefox on June 30, 2025 on my Dell desktop computer that runs Windows 10, most of my bookmarks are no longer visible. Only four of my bookmark folders are visible and most of their contents have disappeared.

However, 1) my uncategorized bookmarks - those in "other bookmarks" are still visible, and 2) If I go to "Manage bookmarks" and do a search, I can find all of my bookmarks including those that are no longer visible.

In addition, I can no longer add or delete bookmarks. It looks like I can do add a bookmark and it will let me go through the steps of adding a book mark - it even says I can put it in all my old folders that are otherwise no longer visible. But one I complete the process the bookmark does not show up.

I have read multiple Firefox Help articles about disappearing bookmarks and have taken all the steps suggested including: - Attempted to restore backups of bookmarks - didn't work. It shows me the multiple old backups but when I try to restore one I get the message "Unable to process the backup file". I have tried it with at least four of the old backup files - all without success. - cleared cache - did troubleshooting mode - refreshed Firefox - uninstalled and reinstalled Firefox - looked to see if I had a different profile other than my default profile that I could switch to. I do not see another profile.

Nothing has helped. Any suggestions would be greatly appreciated.

Thanks
