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.

Hi. News videos from www.bbc.com won't play. When I ask the BBC website to play a video, I get a blank area of my screen, with a play button. Clicking the button makes it go away, leaving me with just the blank area of the screen. Videos from youtube, movie trailers, etc play fine - it's just videos from a few sites (such as BBC) that yield nothing. I have autoplay videos disabled by default, but: I'm not trying to have the website autoplay; The setting doesn't affect other websites; and there's no way to disable autoplay for the website I'm on (no way I can find, at least).

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 am an EX EU employee and have access via a double authenticated procedure to the "EU LOGIN" which gives me access to several internal webpages of my former work organisation. The most important is the access to the HEALTH SERVICE, which actually is blocked since one week-- and now it seems like this-- through your web browser. I am an ancient Mozilla user and supporter. After claiming my help desk in EU that my EU LOGIN is blocked, I got the answer, try to use another browser- and I saw that with another browser it worked. What happened with Mozilla? Do you want me to go to apple-microsoft or what ever?

This problem can sometimes occur if cookies are disabled or rejected.

I'm experiencing an issue when copying PNG images only in the Firefox browser. Here's the problem: When I copy a PNG image and paste it into Photoshop or any other program, I get an image with a black background.

This didn’t happen before, but it started occurring after a few recent updates.

In other browsers, I get a “normal” PNG image with a transparent background.

I'm unable to login to account.apple.com on my laptop which is running Ubuntu 24.04.3 LTS.

I've launched Firefox using the `-p` option, created a new profile and then navigated to https://account.apple.com/sign-in and tried to login. I've attached a screenshot of the error message.

I had tried multiple things on my default profile, even troubleshoot mode, but I couldn't get it. I even tried useragent switcher to no avail.

I can login to the site using Chromium.

What else can I try?

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.

Just noticed that Firefox only has translation for Chinese Simplified from Mainland China, but no Chinese Traditional from Hong Kong and Taiwan users. Any plans to get it going? I would hate to switch back to Chrome or Edge instead.

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

I actively use keywords to search from the address bar, mainly g for google, gs for google scholar and w for wikipedia. Until a recent update (until last week, I think), pressing ctrl + L to go to the address bar would select all the text in the address bar, including the keyword, such that if I had made a google search by typing g and some query, I could immediately do a wikipedia search by typing w and some query.

Now, with an updated firefox (141.0.3, on xubuntu 24.04), the search engine from the previous search remains when I press ctrl + L, so I have to type backspace(s) to remove the search engine keyword, before typing a new keyword.

Is it possible to get the old behaviour back?

When setting up 2fa. I scan the QR code. Enter the 6 digit pin generated by google authenticator. Download my backup codes and enter 1 when prompted then firefox says sync time and try again. I am running Ubuntu and have an android phone. Ubutu is set to automatic date. time and timezone. My phone is also set to automatic date&time. I have enabled seconds display on Ubuntu and phone the are synchronized to the second. I have tried this on multiple computers. Google authenticator works with all 9 other 2fa logins I use it for. I have tried many times and asked AI what I'm doing wrong Grok said I am not doing anything wrong after walking through the entire process. I have tried clearing cache and deleting cookies, signing out and back in without success. Please help I use firefox as my password manager and love it but want it to be as secure as possible.

thank you very much. Thomas

Good morning, today I downloaded Debian 13 Mate version and to install Firefox I entered the following commands taken from https://support.mozilla.org/it/kb/installare-firefox-linux#w_installare-firefox-tramite-il-pacchetto-deb-per-le-distribuzioni-basate-su-debian-consigliato and the commands were

sudo install -d -m 0755 /etc/apt/keyrings

wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

echo ' Package: * Pin: origin packages.mozilla.org Pin-Priority: 1000 ' | sudo tee /etc/apt/preferences.d/mozilla

sudo apt-get update && sudo apt-get install firefox firefox-l10n-it

but I get this result OpenPGP signature verification failed: https://packages.mozilla.org/apt mozilla InRelease: Sub-process /usr/bin/sqv returned an error code (1), error message is: Signature by 35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3 was created after the --not-after date.Il repository "https://packages.mozilla.org/apt mozilla InRelease" non è firmato.

What mistake could I have made? Apart from the fact that now we use sudo apt update && sudo apt install Thank you in advance for your response.

When I opened Firefox, all my profile settings were back to a Default. Lost all my settings. Looked up solution on Google, couldn't find an "Old Firefox Data Folder" anywhere.

Tried the other listed "profiles" in my profiles folder, none were my most recent profile with all my settings from the past months.

How can I find the profile that was used before my update which was done 7/27/25 ish.

Thanks, Jean [email removed]

If I don't use the custom adjustments in my Chrome css, seven buttons on that right side of the menubar are hidden, including the min-max close buttons.

This is problematic when I'm troubleshooting Firefox, and the css is disabled. If I want to close or take the browser out of max mode, I must move those buttons to the navbar, which has no such restriction accommodating those buttons, not to mention why is it necessary for that min-max close trio to monopolize 20% of the menubar. Waste of space. Inefficient.

I'm also curious why must that frame at the top of this sites pages remains persistent, and follows the user down the page, so that when you're composing, and accidentally (and all to often) touch one of those links, it get superimposed over the message, and you must move the cursor to the bottom of the page get rid of it. Not to mention, that frame shrinks the working area of the page about 30% vertically.

I mean, once you have already navigated to the destination page, and you're composing, how often/likely are you going to need to access that area?
