After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

This one is puzzling to me: On a website with login, whenever I click on an link to a pdf, a new tab opens (my normal setting) and immediately crashes (not my normal setting ;)). However, everything is fine elsewhere on the web, even on the same site in the sections without login. Here are some observations that may or may not be connected to this:

• If I right-click and open in new tab/window/download, everything is fine
• When I return to the tab where I clicked the link, the page reloads - independent of whether I did anything in the crashed tab
• the site-admins were not able to reproduce the problem, also it seems fine for other users
• the problem persists in troubleshooting mode, also manually disabeling extension did nothing, emptying cache etc. also nothing.

It is not like this is making me switch browsers (although no crashes in edge), but it bothers me to have no idea why this is happening. :) Maybe someone here feels the same? Thank you for reading either way!

The offline package download speed is too slow and sometimes fails. I hope it can be provided separately, like interface language packs, just as Debian has separate interface language packs.

Hello,

After recent macOS updates, it appears that Firefox would get stuck when trying to access passkeys stored in macOS's passwords or keychain apps. I run into this issue with both the following two combinations of Firefox versions and macOS

144.0.2 on macOS 26.0 Tahoe

140.4.0esr (aarch64) on macOS 15.7 Sequoia

Any insight is appreciated!

I went to Wirercutter from the NY Times, tried to search and got the result "HTTP header is larger than 10240 bytes." I performed the same action with Chrome on the same machine with no problems. I am on Firefox 140.4.0.esr running on a Slackware64/15 machine.

I was able to use it this morning from my macbook. But the afternoon I was on sites where my passwords usually fill but now everything is empty, everything had been deleted. I tried to log out and back in to mozilla and sync, but everything is gone. Over 100 sites and passwords. How this happened ? Where can i ask for help since Mozilla doesn't offer any.

I recently ported from chrome to firefox about 3 days ago and was tryin to access the dropdown menus on this website https://www2.gov.bc.ca/gov/content/governments/government-id/bc-services-card/your-card/get-a-card

I realized it wasn't working so I turned off my adblocker (ublock origin), refreshed the site and still not working.

Also attempted to use troubleshoot mode and still does not work.

Cleared cache + cookies and used troubleshoot mode and nothing working still.

I lastly checked the website was working by opening the same link on chrome after all that and it works perfectly fine over there. Any ideas what could possibly be the issue?? I basically have a fresh install of firefox with no changed settings besides anything that might of been copied over from Chrome when firefox automatically asks you to migrate your stuff over, and used the troubleshoot mode + clearing cookies and cache

Power outage after using a new Imac for 2 weeks. Now no bookmarks and no History showing in Firefox. I followed all the steps given in SUPPORT 1. Export HTML bookmarks from old computer. Import on new computer. 2. Load Backup bookmarks (JSON file) to flash drive. Load into new computer. 3. Copy latest Bookmarksbackup file found in new computer to Desktop.

'Each of these methods hit the same brick wall'. Firefox Menu > Bookmarks > Manage Bookmarks > Library Screen and choose "Restore" or "Import Bookmarks from HTML" THE SCREEN IS BLANK WITH NO CHOICES TO PROCEED FURTHER.

the attached image showsThe most I was able to accomplish is to copy and paste a bookmarksBackup file into a box and then nothing.

Why don't any of these recovery methods work?

What follows describes what I think is an annoying bug, and as I'm writing a draft of the bug report, I thought I'd post it here first to make sure it's understandable, and if possible to get others to confirm the bug.

In Tools - Settings - Files and Applications, with the following settings: - Always ask you where to save files is ON - What should Firefox do with other files? is set to Ask whether to open or save files

If a file type is not defined in the Applications list/grid, Firefox 140.4.0esr displays the Open or Save box (only Save for .exe files) If you click Save, FF opens a save window according —logically— to the path defined in Tools - Settings - Files and Applications - Downloads, so - The list of files shown to the right is correct, - But the path shown in the toolbar above it is wrong (> ComputerName > C:\ > in my case), - And the selected folder in the navigation column to the left is also wrong (ComputerName in my case)

and that always throws me off.

The bug appeared before FF v140.4.0

Test downloads - Go to https://openexr.com/en/latest/test_images/TestImages/AllHalfValues.htm and click the link below the AllHalfValues.exr title - Go to https://www.picsellia.com/post/tiff-tag-image-file-format and right-click on one of the pictures at the top, select Save Image as from the context menu.

Please post a brief message below to confirm or invalidate my finding. Thanks!

So my question is Firefox is on my Cent OS 10 machine and it only shows the close button on the upper right corner, I would like to know two things, 1. How to add the Minimize, Fullscreen buttons to just the close button on the upper right corner. 2. How to get my menu bar back - the home button and all of the other goodies that normally show on the left of the browser just above the Forward, back and refresh buttons?

Thanks in advance for the help.

no matter what I try I cannot get any content from HBO max, crunchyroll, or spotify to play. I feel as though I have tried every troublshooting step. In firefox 140.0.4 64 bit on windows 10 I have:

-turned DRM off and on -disabled and re-enabled widevine -disabling all extensions -try in a private tab -turning off tracking protection -clearing cookies/cache/site data -uninstalling and reinstalling firefox -trying on firefox nightly -trying on other firefox based browsers zen, librefox same issue. chromium based browsers and firefox on my windows 11 laptop play drm content like normal -manually installing older version of widevine -changing useragent to chrome(this triggered cloudflare and would not let me pass) -making another user in windows and trying there

the error i get on crunchyroll is code: DRM-0 and on spotify it loads but the play icon does nothing. in hbo max i get error code 1k-0003

At this point I don't know what else to try, If there is not another solution I probably try to just switch to brave browser or wiping this pc and reinstalling windows.

I joined a Microsoft Teams meeting through Firefox on the web on a Linux machine. When I tried to share my entire screen, I was asked if I wanted to share the entire screen in a Firefox pop up which I said yes. Then the "you are sharing your entire screen" came up, the sharing icon was red and the "stop sharing" button was red. See attached image. This all disappeared and reverted to the default state almost instantly.

Teams has a feature to "manage what attendees see manage what attendees see" where the meeting host can preview shared content before making it live.

I am concerned that the meeting owner was able to see my entire shared screen without me even knowing it through this preview.

Can someone help? Microsoft just sends you around in circles and I can't contact Mozilla.
