Firefox loads in some images very distorted where they are pixelated and in negative color. It's not all images, it's also not on specific websites, it's just in general. Some websites don't have any problems and others are practically unusable. The icons in my tabs are often desaturated from their normal color as well, see the youtube icon for example the color is very muted versus the actual color of the logo.

Hello, since I installed the Firefox 141.0 update today, I can't login to Reddit. I tried logging into Reddit right after updating Firefox, so did a System Restore to see if that corrected the problem, and it did.

To double check, I installed the Firefox 141.0 update again, and encountered the same problem logging into Reddit again, so it's definitely this new update causing the problem.

I've attached the Reddit messages I get. The 1st is the initial message, and the 2nd after I retry logging in.

I would greatly appreciate help with this.

Thank you,

Michael T.

How can I customize the headers and footers of a print job? Specifically, I want to change where the header and footer info appear on the page, i.e., left corner, center, right corner. I'm using Firefox Browser version 141.03. Under Print > Options, the only option is to show or not show the headers and footers. There is no option to EDIT them. Thank you.

What the hell do you guys do with the latest update?? My home page is all screwed up and does not look or act at all as my old home page. Apparently there is no way to go back to the "old" look and feel. Not a good decision. Seriously thinking of abandoning Firefox (since I used it in WIndows-7) for a browser that will make my life easier, not harder. At 81 years old I don't time to waste futzing around trying to get my home page to work. "Technology getting in the way of Life." If someone want to guide me to getting my old Firefox home page back, email me. Bob

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

Hello,

I’m experiencing an issue where I cannot use ChatGPT-5 in Firefox. When I log in and try to select or use GPT-5, nothing loads or functions properly. Other models like GPT-3.5 work normally, but GPT-5 does not respond.

I’ve already tried refreshing the page, clearing cache and cookies, and even disabling extensions — but the problem persists. Could this be a compatibility issue with Firefox? Any advice or support would be appreciated.

Thank you in advance for your help!

Hi All,

I am trying to setup 2-Factor Verification for my Mozilla account however every time I enter in the 6 digit code it shows up with "Invalid or expired code. Check your authenticator app and try again."

And I am positive I am doing it right. As I would normally do it; scan the QR code, enter in the 6 digit code.

If anyone has the same issue or solved it, please let me know.

I have been trying to clear out the cache under settings (cookies & site data) (everything is checked under clear data) everything clears out except for 440 now 454 KB of disk space. I cannot get it to clear out. I even uninstalled fire fox and it was clear for a couple of uses and now it is back and instead of 440 it is now 454. ••• Cookies and Site Data Your stored cookies, site data, and cache are currently using 454 KB of disk space. Learn more Based on your history settings, Firefox deletes cookies and site data from your session when you close the browser. ••• How do I zero it out. I find this annoying.

Thank you, Teri

Every now and then Firefox asks to to shut down the program and reopen it. But when I do that I lose all the open tabs I had before. I also tried the new container tab system but it doesn't work

My Mozilla Firefox bookmarks are Bookmarks 2025-07-22.JSON. They worked well on my older Dell computer. I bought a new Dell desktop computer. I am disgusted with Google. My bookmarks on my C Drive. If you can't help me reload those bookmarks, I may as well decide to delete Firefox and use another such as Total Browser. I certainly hope you will help me load 2025-07-22.JSON on my new computer - it is ridiculous that Firefox wants to put in the full address on the C Drive instead of simply loading those. On Firefox on my last computer I used News which was bookmarked Daily Wire, Epoch Times, Salem News Channel, God's World News, One America News, Washington Times, New York Sun, and local Sterling Virginia Weather. I also use biography sites https://www.Worldhistory.org and Britannica.com [both of which I pay for monthly, as https://www.wikipedia.org/. I also have a Biography folder with names from A to Z I also have many music folders 1940s, 1950s, 1960s, 1970s, 1980s, 1990's, 2000s, Music group and singers A to Z, Blues music, Bluegrass, Christian Alternative Music, Country classic, Country & Western Gospel, Folk Singers, Jazz, Motown, Soul and many others which I have gathered over the past 10 years

I use Nordpass password manager. If I try and open a site from Nordpass , Firefox Relay overlays the page , preventing the use of Nordpass. How can I disable this Firefox Relay?

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

All of a sudden, I can't access several websites through Firefox that I have used for years -- but I CAN access them in other browsers, like Chrome and Safari. Also, Firefox no longer works with my password manager. Until about two weeks ago, I could always autofill login information, but no more.

What gives? I am up to date on my IOS (Sequoia 15.5) and on my version of firefox -- and my password manager app. Superfrustrating. I hate to have to turn to Chrome as my primary browser since I hate Google, but I might end up doing that and just not using Firefox anymore, after like 20 years of having it as my primary browser.

I have Mozilla Firefox as my browser on my i phone. I noticed an exclamation symbol saying" enter your PW to connect". I go to firefox.com/pair on my desktop. I navigate to the QR code and take a picture. I confirm the desktop with the i phone. Then it asks for 2 step verification code from an authenticator. I don't get one. So I download an Authenticator app. And nothing shows up there either. The problem is getting a code from an authenticator to complete the process. What should I do?

I have my credit card info saved and previously I could click on a credit card and it would autofill the numbers for me. Now the credit cards still show up when I click on the space to put the credit card number in but but it wont fill the info into the form. I just get a blank space after I click on the saved credit card. Any suggestions on how to fix this? Thank you for your help.

Firefox stops loading pages. I try to browse a webpage and it just keeps loading, but nothing happens (black screen). I open chrome, request the same webpage, it loads immediately. In Firefox, it keeps loading. Sometimes it loads it after 1-2 minutes. Sometimes not. Problem is fixed after restarting firefox, but comes back again after some time.

Hello there,

Before (an update perhaps?), it was possible to click on a star icon located in the toolbar and it'd open the bookmarks like the bookmarks1 screenshot. Now, it requires to first click on the sidebar thingy, which allows to access the icons on the far right, which includes the bookmarks icon in question.

There's also another icon for bookmarks that can be put directly in the toolbar (bookmarks2 pic), yes, but it doesn't show all the bookmarks right away, it's not the same

So the question is: how do I do to get the Ctrl B Icon/shortcut directly in the toolbar, like it was before? I don't want to be obligated to use the sidebar when I have plenty of space left in the standard toolbar..

Thanks in advance!

I just approved an upgrade to Firefox that mentioned something about a new way of dealing with extensions. The first thing I noticed was my 1Password add-on in the toobar disappeared. I took the steps recommended by 1Password to add it back, and I can get a 1Password icon to appear on the toolbar, but it is non-functional. I confirmed 1Password is still functional with an icon in the toolbars of my other browsers. What gives?
