Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

i used to be able to access Gemini by clicking an icon in the leftmost column of any Firfox screen. I nw get an error 502 message. How can restore access to Gemini

My iMac automatically updated to the latest version of Firefox and now Firefox won't open at all. I keep getting an error message about installing a helper tool. I tried both installing the Helper Tool and canceling (see attached image) with no success. Please advise.

Thanks! Carol Boehler cboehler2@unl.edu

Bonjour, lorsque je veux me connecter à ma boite mail Zimbra de Free un message indiquant "chargement en cours" s'affiche après avoir rentré mon identifiant et mot de passe mais rien ne se passe, la page indiquant se message reste fixe. Pour info je ne rencontre pas se problème lorsque je me connecte avec Google Chrome. Merci de bien vouloir m'indiquer ce qu'il y a lieu de faire pour solutionner ce problème. Cordialement,

I struggled some time with download links, no matter what filename I specified in the download="filename" attribute, the file I got was always download(1..n). Now I put all into one zip archive. I have a german and an english page, the link is:

Alle Skripte hier zusammen in einem ZIP: <a href="../downloads/backup.zip" title="Download Backup Skripte" class="ilbutton" download>backup.zip</a>

in der deutschen und

Here all together in one zip file: <a href="../downloads/backup.zip" title="Download Backup Skripts" class="ilbutton" download>backup.zip</a>

. I can't see a difference except the language. But: the download of the german link comes as "download.zip". The one from the english one as "backup.zip". WHY???

Thank you for any proposals!

Whit the new things of the profiles or something I just didn't like it so I just delete the thigs that appear in my face, but that deleted all my stuff(hystory, bookmarks, passwords), I supossley had all on my account on mozilla but it's not there, i don't know what to do, I already try the backup or something that appear in the support page but the only profile that is older than the rest doesn't work or is empty, pls I need help

I have very often issues with Firefox/Captcha. Captcha is not recognized by GFirefox, and the communication with the website using Captcha is blocked. It is very irritating. When it won't be fixed I need to move to another browser

I normally have 4 windows open, each with multiple tabs, for 4 work streams.

Whenever Firefox or MS decides to do an update, one window sometimes, 4 rarely, none usually, are recovered after restart. How can I ensure that Firefox remembers all the windows and their tabs before shutting down? Then reinstates them after starting up. After the last MS update, the option "Recently closed windows" was greyed out. But there had been 4 of them.

Firefox's recovery after simply rebooting the computer is more, but not completely, reliable. Win11 on a desktop computer

Thank you

In previous versions of Firefox, using an alternative search engine was seamless: I just typed my keywords and clicked the specific search engine icon.

With the current update, the workflow is much longer. Now I have to:

1. Type the keywords 2. Click the dropdown arrow 3. Select the alternative search engine icon 4. Hit Enter

Why was this UX change made? It feels like a step backward.

I recently set up an ex-Win10 PC as a Linux media player and was delighted it came with Firefox. I created a separate profile on my Win11 PC for use on the media PC. In this profile I have a few stored bookmarks, log on IDs * passwords, for sites such as BBC iplayer etc.

I did eventually manage to load it on the media PC but when I went back to my Win11 PC I couldn't find my original Firefox account. When I tried to switch accounts, it wanted to load all my original bookmarks etc and combine them in the new profile.

It's now evident that I didn't realise the difference between accounts and profiles (and I'm still somewhat confused). I can't find any clear help on how to switch between accounts and profiles. Why am I finding it so difficult? Perhaps Firefox is being too smart for me.

I cannot listen music from browser through bluetooh attached device. I ave a bluetooth speaker which I use for all apps on my laptop. Today I noticed that it does not send signal to the BT speaker but through the laptop speakers. What can I do or what settings should I change. Laptop and BT speaker are paired. Thank you!

Hello,

I have just setup a new desktop computer which has the latest versions of Firefox and AVG Free.

Firefox is not working properly, sometimes not completely loading pages, images or is not loading pages at all.

If I disable the AVG Web Shield Setting “Enable QUIC/HTTP3 scanning” then Firefox behaves normally.

The build of AVG Free is 26.3.10886.974 and the version of Firefox is 149.0.2.

Hi,

This is since the last 2 updates.

I usually maintain 2-3 active windows with multiple tabs. Everytime I turn off my PC, when I turn it on again, and I open Firefox, all my windows and tabs would be restored as I last left them. And if I accidentally closed the windows, I can select reopen Recently Closed Windows.

But since the last 2 updates, after I close the window, the option to reopen Recently Closed Windows were still grey.

And it's a hassle that every time I restart my computer, I need to go to Restore Previous Session to have my tabs open again.

And if I or another user opens it and started a new tab/session without restoring, I will no longer be able to restore my previous sessions and would lose all my tabs.

Can you please tell me why the feature is changes, and is there a way I can easily restore my previous sessions without the trouble.

Thank you.

I face an issue with the browser crashing when in google meeting (meet.google.com). The problem persist in a new profile created with 'firefox.exe -P' and also in the troubleshooting mode. The crash is triggered when I am in the google meeting (with allowed microphone) and I manipulate with windows of the browser - across multiple monitors (switching tabs, moving tabs between windows, closing firefox windows, opening them, "dropping" the tabs onto another applications - chrome, spotify - which opens a new firefox window). Sometime the crash happened once I closed the google meeting tab. Unfortunately it happens "randomly" and I was not able to come with a specific series of steps to reproduce the crash. But it happens always when I am in the meeting and play with the windows for a while.

The crash: Firefox freezes for a few seconds (~3s) and then closes itself - all windows. %appdata%\Mozilla\Firefox\Crash Reports\pending contains a new .dmp file, but it has 0 bytes and no .extra file is created, hence it cannot be submitted via about:crashes. The crash reporter is not opened when firefox crashes. The attached troubleshooting information are from the new clear profile where the crash happens as well.
