Hmm. We’re having trouble finding that site.

We can’t connect to the server at healthy.kaiserpermanente.orghttps.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

What does this mean and how do we fix it?

Trying to connect to my insurance company's website, it does not show my info, puts up a statement "You are in Privacy Mode. Your web browser does not support some features at the moment. Live chat may not work properly for you. " What's wrong" Windows 11.

Hi, I'm using Firefox 64bit (version 144) on my Windows 11. I've noticed that I can no longer drag tabs around or detach them. I would guess this started with the latest version because I could do that some short time ago.

I've already tried the following:

• Restart of the browser - did not help
• Restart of the computer - did not help
• Start firefox in safe mode (Troubleshooting mode) - did not help
• Tried changing browser.tabs.allowTabDetach - did not help

I'm not sure what could be the problem. Does anyone experience the same issue?

Hello,

I wanted to ask if there’s a way to configure the setting for "Store data in permanent storage" (or "Daten im dauerhaften Speicher speichern" in German) to always block/disable ALWAYS via Group Policy or Registry Editor.

As we are a small company, I would like to apply this setting for all Active Directory users.

Thank you

Best regards,

Andreas

I was wondering if there are any fix for this glitch I am encountering in this website https://currently.att.yahoo.com/ | I get the log out successful when I try to sign in, this is site is working fine in other browsers but I want to use firefox for it.

Hello. I had been experiencing a lot of freezes, hang ups, and disconnectivity with crash messages asking me to either restart Firefox, or quit firefox ! I finally just recently downloaded again from your website and in order to function it defaulted to Safe Mode. How do I correct this ? Note: The website is currently operational but not at 100% ! When in Settings nothing can be done and it advises that it's because it's in Safe Mode ! How do I correct this ?

Moderator note: this question has been edited to correct the formatting.

Just what the headline reads, I have had zero problems before but with the new update my browser keeps slowing down and crashing on DuelingBook (a yugioh sim) even though it never did before. I havent tested other sites, but pokemon showdown works still so I wonder what the problem is.

I do not live in Estonia, I don't know estonian, I don't have estonian set as a language anywhere in firefox or any other settings, I don't have any estonian language packs downloaded, the only time I was involved with it was when I accidentally clicked on 'estonian' instead of 'english' when trying to translate a page (once, I clicked on it accidentally once as far as I remember, one single time and no more. Only one time this happened. Once), and it somehow just can not cease asking me to translate pages to estonian, anything that isn't in english, somehow it tolerates that. Actually how does this happen and how do I fix it

Hi, somehow I managed to delete the Firefox account I've used forever. Is there any way you can reload the details of that account? I've downloaded another Firefox but there are no saved items, bookmarks, etc. Totally disgusting, but I can't somehow sign into the old account as my password manager does not currently have the right password, only the password I just made up for the new account. Dang, sigh, etc. Thanks for listening, BBart
