Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.
       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 


The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

Hello dear helpers, When I click on a webpage link (or right-click a link to open a tab in a container), Firefox repeatedly opens the same tab all across the tab line; maybe 20 or more of the same tab. I would be grateful for help if anyone knows how to solve this. Thanks, -AnneF

I downloaded the most recent Firefox update (version 139.0.4) and since then, Firefox has been prompting me to restart to continue using Firefox every day. When I give the go ahead to restart, I get a pop up that says I need to either exit the Firefox client completely, or create a new profile to continue using it because Firefox detects an older version (this is even after updating it manually).

It's made about 5 profiles since the 10th, and they're all still in tact. I clicked my very first one and it very much still works (and even gives me a popup when I open it in a new window that says Firefox is using the latest version). It's been really disruptive to my work flow as it has happened several times in the last two days. I keep checking my settings and it says that I'm updated to the latest version of Firefox, but it continues to kick me out.

400 Bad Request "Failed to convert 'userIdEncrypted' with value: ''" on login form submit to Truist

When I use non-incognito browser to go to https://www.truist.com and enter a login and password that is valid I receive a JASON response message window that says {"type":"about:blank","title":"Bad Request","status":400,"detail":"Failed to convert 'userIdEncrypted' with value: ","instance":"/dias/authenticate"} If I use a new private window I can login normally. Others have said the same thing but the suggested remedies do not work. I have delete all cach, cookies, and site data associated with the truist.com domain and the same problem happens. If I use Edge all works well with the truist.com site. Where does this useridEncrypted come from? Anyway, I thought I would try to clear out the userid which was prefilled in with the help of Firefox and just retype my id. Viola, everything worked. So wherever Firefox is retrieving the saved login id from, that must be corrupted somehow. Hope this will help somebody that is experiencing this problem.

PLEASE HELP! I allowed Avast to do a "clean up" this week. That usually entailed a "scan" for viruses. NOT ANYMORE! My computer is really messed up! I just tried to delete Avast, and even though I hate to see ads, I think their Ad Blocker is messing up my PC. I just noticed that when I asked what I thought was FIREFOX a question, the answers were supplied by an entity called THLIOKNI. WTF is THAT?????? Seriously, what is happening to my relatively NEW PC--had to buy a new CPU in October of 2023. And I've always used Firefox. But WINDOWS 11 is the operating system on this PC, and it is NOT compatible with Firefox apparently! I'm an elderly woman and I cannot handle this stress! What I also noticed is that I read Substack writers and depend on them for accurate description of current political and social news, but now I can't access the "like" buttons on commentators. Is that a Substack issue (I don't think so!), or is it something to do with the Avast "clean up?" WHAT ON EARTH IS THLIOKNI and how the hell did that get on my computer? PLEASE ADVISE ASAP! And I sincerely hope a REAL PERSON reads this! I do not want a million responses from other readers at other times, I want to hear from a REAL PERSON! You have my e-mail address. Catherine O'Kelly

Passwords simply don't sync properly to iOS

I use Firefox (139.0.4 (aarch64)) on my Mac as my daily browser. I also use Firefox as my primarly browser on iOS (139.1 (56110)). My passwords simply don't keep synced between the two. I'm logged in to both using the same Mozilla account. Some passwords sometimes sync. But many are missing on iOS, and many that are there are out of date. I've done the usual like logging out and in again, I've tried forcing sync manually, passwords are set to sync on both devices. This has been going on for years now and I'm at the point where I'm going to have to switch browsers as I can't keep not having access to my passwords on my phone. Any ideas on how I can fix this? Thanks!

For the past 2 days, Facebook won't load when I try to change my page to another (just switching between accounts). It acts like it is changing or loading, and then I just get nothing. I have done all of the things that are requested from clearing my cache, browsing data, restarting, etc. Nothing is working. I've attached a picture of my screen of I receive when I try to change pages - the big F. LOL Facebook on my phone works fine. I've tried also turning off my VPN and it doesn't load.

I've also had issues with my Xfinity email loading unless I turn off my VPN.

So what is going on?

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?
