Hi. Recently, not sure of which version as there seems to be a lot of updates :)

I'm currently on 152.0.1 on a Windows 11.

This problem doesn't happen on my Raspberry pi with 152.0 (aarch64) On my Android 13 I have allowed Pop-ups, via about:config, sort of, but there is no option to make Exceptions

So back to Windows 11.

As said I can enter an exception and that works when I load the site I want until I close Fx and I have to do it all again: Enter Domain : Allow : Save etc.

Once, and only once, I closed the [settings] and I'm sure after closing FX and opening it worked fine.

Just closed again and problem has occurred.

The issue arises on my site https://calstock.org.uk which opens a window to a UK weather site, The Met Office. It requires cookies etc. and shows it's own popup.

What I do is open it first in a new window, which is the popup I am referring to, then I load it in an iframe, then I close the popup.

That way the cookie is set by the new window that pops up so there is no query on my main page.

I only have the one extension, uBlock Origin which I have on all devices

Thanks

Hello, Im using localized (Lithuanian) version of Firefox. Several updates back, Firefox started including russian and Polish in preferred languages by default. Personally i know how to remove those for myself. However, since im managing around 300 computers in a school. This starts to become an issue. In Lithuania we only have one official language. And when pages in a school start opening in foreign (russian) language this starts to be quite annoying. I would love to keep using Firefox but i need help.

when i updated linux a newer firefox version was installed but none of my personal settings, passwords or bookmarks installed onto the new firefox version. can't access my previous profil on my computer

I'm trying to add the world cup tracker to my home screen, but when i click the link, it just puts me in my new tab page with no changes. When I click the pencil edit icon, widgets are not an option for me. Is there a place I need to enable them?

Hello,

Since this morning, I haven't been able to access Bsky on my laptop because of a supposed HSTS risk, which means I can't add an exception to visit it. I use Firefox on my Android and going to the mobile version of the website lets me in no problem, so I assume there's an issue with my laptop.

I'd usually wait a few days and let it solve itself but just in case it's something on my end, I'd like to solve it! I'm on 151.0.4 (64-bit), don't use a VPN or an anti-virus, I have a couple of privacy add-ons but they've been here forever and they've never caused a fuss. I can post a screenshot of the error code and the certificate it sends me if it's any help.

I'd appreciate any pointers! Thanks!

I have [[created a backup file|https://support.mozilla.org/en-US/kb/firefox-backup#w_protect-your-sensitive-data-with-a-password]] today with the latest available Firefox and switched to a new OS. Sadly, the backup file somehow seems to have gotten damaged, even if Firefox still recognizes when I'm inputting the wrong password. On Ubuntu, where I originally created the backup and where I tested it again after things weren't working out, Firefox tells me that there is an issue with the file and that I should try a different one (which I don't have). On CachyOS, which I'm currently testing out, restoring the backup never finishes and Firefox doesn't exit cleanly. In hindsight I obviously should 1) have tested the backup immediately, 2) not have wiped my laptop prematurely, and 3) have backed up the folders manually, but I haven't. Now the question: is there some way to extract the account details from the .html file? I don't care much about the rest, but restoring the accounts in some other fashion is gonna be a lot of work.

Hello,

I like how easily I can access bookmarks, tabs from other devices, and the chatbot from the "Tools" bar on the sidebar, but it becomes inaccessible after enabling "Expand sidebar on hover".

See images attached showing before and after enabling "on hover".

Am I missing something? Is there a workaround?

Thank you.

I am unable to access even my regular haunts, quite often lately. Sometimes I'm able to access the site by taking Enhanced Tracking Protection off, but oftentimes not. I need to use Edge!!! And I get the message "The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem." I have gotten that message AT BANKING SITES. It's become too annoying. Tried adding exceptions, to no avail.

ExitException[ 3]javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure at sun.plugin2.applet.JNLP2Manager.downloadResources(Unknown Source) at sun.plugin2.applet.JNLP2Manager.prepareLaunchFile(Unknown Source) at sun.plugin2.applet.JNLP2Manager.loadJarFiles(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

With the new organization of Settings, my list of cookies has disappeared. I was trying to delete cookies from a specific site, but when I go to that option in "settings," there is no list of cookies.

I have tried restarting both Firefox and my computer and the list is still missing.

Any suggestions on getting it back?

I am trying to get Russian language spellchecked.

I went to this url: https://addons.mozilla.org/en-GB/firefox/addon/russian-ru-language-pack/, installed the pack. Re-opened the browser. But nothing seemed to changed.

I use English locale.

I just downloaded the latest FF having had an old account. Working fine but I continually get a message that I am on windows 10, which is wrong. I am on Windows 11. The message has worn out its welcome. Is there a way to fix this.

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

Hello, I am facing a very strange and frustrating issue with my website https://biografieblick.de/, and it is only happening on the firefox browser other browsers like chrome, edge or safari are loading the site perfectly fine. The Issue is it occurs occasionally, Yeahh IDK why. When I try to visit my site, Firefox gets stuck on a screen that says "Checking if the site connection is secure" and it looks like an loop sometimes.

This looks exactly like a cloudflare turnstile loop but I am NOT using cloudflare. I have double checked my DNS records and explicitly confirmed this with my web hosting provider. This block only triggers when using firefox.
