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.

When attempting to access the Twitch website in normal browsing mode, the page does not load properly. Instead of the site rendering, I only see a black screen with an infinite loading spinner.

This issue does not occur in private browsing mode (incognito), Twitch loads normally there.

I found that performing a browser reset temporarily resolves the issue, but after some time the problem returns. Continuously resetting the browser is not a practical solution.

Additional details:

   Browser version: 141
   Steps to reproduce:
       Open Firefox in normal mode
       Navigate to https://twitch.tv
       Observe black screen with loading spinner
   Expected result: Twitch should load normally
   Actual result: Page remains blank with a loading spinner
   Private browsing mode works correctly

Please advise on a permanent fix or steps to diagnose this issue.

Hi,

Today when I powered on my pc and opened up firefox all tabs were lost.

I have the option to retain tabs when opened up enabled.

I could not find them anywhere, so I had to search opened tabs from the other synced devices and click on each of them, and create again all the tab groups.

This is a big problem if randomly all the tabs can get lost, am I doing something wrong?

Another thing : I thought that when I create groups of tabs, and save them I coul retrieve them across all my synced devices, but the other devices can not see those groups, is this a normal behaviour?

Thank you

I am using Firefox desktop on Windows 11. I have downloaded hundreds of articles from this website, with no problem until yesterday. I accessed the website using Edge, and it worked fine.

When trying to access a particular article to download it to Ancestry, the following message appears:

I accessed the browser console for more information, which I'm sure someone can understand, but not this grandma. This is what I got:

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.

After my bitwarden add-on failed me, I remembered ChatGPT helping me with this another time - but I got it wrong. I right clicked the extensions button (I have 3 add-ons falling under that button) and removed from tool bar, thinking I could then reinstall it and the Bitwarden issue would rectify.

Instead, the extension icon disappeared, and is nowhere to be located. ChatGPT wants to do some reconfiguring but surely there's a better way. I have looked in "customise toolbar" (ie, right click toolbar, click customise toolbar and look for the icon" - but the puzzle piece icon is not there.

Surely I have hidden the puzzle piece icon somehow and I need to do some sort of magic to make it reappear... Have never had this issue with Firefox previously.

Dark mode in Firefox has broken just now. The issue appears restricted to Firefox - all other elements in environment (Ubuntu/Cinnamon) appear to be operating correctly.

The elements at the top of the screen and some menu screens are now white rather than dark grey. Due to a neurological condition this causes near-instantaneous cluster migraines.

Is there a way I can fix this? Is there a way you can fix this? Is there a way to access the web without a browser? (eg through the text terminal)

I am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

Sample Messages:

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?

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.

Since a few weeks I have been encountering an issue where tabs in Firefox would frequently crash. I do have various add-ons installed, however I haven't installed any new ones around the time the issue has been occurring. I've been unable to track down which add-on or if any add-on might be causing this.

Trying to search for this issue all I could come up with is that it might be an issue of a faulty CPU. I have an i9-13900KF which has been known to be part of the Intel generation with serious flaws. However I already installed a BIOS update and applied Intel's recommended settings to undervolt the CPU to prevent any issues. This was well before the Firefox tab crashing issue happened. So I'm not sure if it can really be the issue of a faulty CPU, but I've also had issues of other programs randomly crashing recently (like Discord or Steam).

The tab crash can occur on any website, for example Youtube, Duckduckgo, Protonmail, etc. The crash reason always is either "EXCEPTION_ACCESS_VIOLATION_READ" or just "EXCEPTION_ACCESS_VIOLATION". The crash also most of the time (but not always) occurs when loading the page itself or a video / live stream on it. But not when browsing an already loaded page (for example this forum post page I'm writing right now).

Here are some of the crash reports I've submitted:

EXCEPTION_ACCESS_VIOLATION_READ: https://crash-stats.mozilla.org/report/index/60309ae8-8cad-43ac-8b9b-172b10250815 https://crash-stats.mozilla.org/report/index/fecef0ab-d874-4cb5-990b-e49650250815

Rather rare "EXCEPTION_ACCESS_VIOLATION": https://crash-stats.mozilla.org/report/index/114b26fa-4e10-442c-bbd5-406630250812


Could someone help me narrow down this issue? Can it really be a faulty CPU and I need to trade mine in?

Hello Mozilla Support Team,

I hope you can assist me with an urgent issue. After reinstalling Windows on my PC, I lost access to my Firefox Sync data, which includes years of bookmarks, saved passwords, and browsing history.

Before formatting, I had been using Firefox Sync with my Firefox Account (sometimes signed in via Google). However, after reinstalling Windows and logging back into Firefox Sync, my data no longer appears. At one point, I saw my account showing activity from just before formatting, but now that is gone as well.

I am worried that my synced data might have been overwritten or lost during this process. Unfortunately, I do not have a local backup of my Firefox profile.

Could you please help me: - Verify if my Firefox Sync data is still stored on your servers. - Assist with recovering my synced data or advise on next steps I can take. - Provide any guidance on preventing data loss in the future.

Thank you very much for your help. I look forward to your response.

Best regards.
