On all sites where I need to login with my work account I get a tab crash when the browser redirects to https://login.microsoftonline.com/ac4b0eb0-811e-4ab0-acca-8a87079290dc/oauth2/v2.0/authorize?response_type=id_token&scope=user.read......

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.

Updated FF Tuesday evening and noticed first on Wednesday when unable to log in to my Tesco food website. Access not allowed from this server or some such. I tried to use the Tesco feedback form and then got alerts both from Avast (saying it was infected) followed by FF refusal to connect. I tried safe mode and removing and adding FF.exe to Avast without change. I reset FF without change. MS Edge allowed access to all these sites without a murmur.

Today i can get to Tesco main site but still not Feedback.

Also my local Synolgy NAS now has a warning that it is dangerous to access from FF. Nothing has been changed in its set up or security. I can and do override and access everything

Something in the Tuesday update has caused this clash. I did think at one point I also saw 120.0.1 being offered but that may have been my confusion.

Happy user of FF fro many years and do not want to change.

I need to be able to access banks, specifically USB Direct. I can access my credit union but when I try to get my statement, I get a message that I have been logged out due to inactivity.

The problem persists across different sites I frequent, most notably dropout.tv and archive.org. videos I try to watch either don't play in the browser at all, or play without any sound, even though nothing is muted. The only site completely unaffected seems to be youtube, where everything works as usual.

"guh your tab just crashed" messagge crash my macbook pro. Also other programs. And yesterday i format and reinstalled an old macbook with catalina and firefox..nothing more..and the same messagge appears..c'mon guys.

Dear Sir/Madam,

I need help with Mozilla Firefox 119.0.1 (64-bit) version which is almost not working internally without Internet link. When I try to open local internal site Mozilla Firefox waits to open https://www.bootstrapcdn.com/ Internet location which is unavailable because we are using the browser in isolated network and it is waiting for this site for more than 15 minutes before it opens the local site.

This is not the way we are expecting the browser to work so the question is can we disable this requests in Mozilla Firefox that we were not aware of and that are not asked from out side?

Thank you!

After the latest updates the drm protection prevents any streaming of hbo or prime video content to discord. Is this just a mistake from mozilla's side or did 2 streaming sites decide on same week to start ruining their service for paying customers?

Recently reinstalled Firefox for Windows on a new PC, and have since been having issues with audio playing on only Twitter. I have tried reinstalling my sound drivers, clearing the browser history and cache, clearing Twitter's cache, reinstalling Firefox, disabling all my extensions and nothing has worked. Any help at all would be appreciated.

It is ONLY Twitter, and it works on all other browsers.

I am in Europe. My Bank is in the U.S. I can no longer log on and access my account through this Mozilla Browser.

I continually receive this message:\Secure Connection Failed

"An error occurred during a connection to click-notification.capitalone.com.

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

This is my ticket (116230) from my initial request.

What can I do?

Trying to access my Tesco account but a page saying 'Access Denied on this server' appears. Can you rectify this? I urgently need to login to my Tesco Account.

PS. I have tried to solve the problem for 2 days but no success!

I like to keep my browser windows slightly smaller than my desktop. I usually leave about a half inch or so free on each side. This way, I still have easy access to any desktop shortcut that is alone the top/bottom, or left right of the screen, without having to minimize my browser windows completely to see the entire desktop. But for some reason, for the last several Firefox versions, it will always resize its height to take up the entire height of the desktop. The width stays the same, the way I want it. But the height is always from the top of the screen all the way down to the task bar. I don't know if it happens every single time I close out of Firefox and reopen, but I know my manual resizing never lasts long. what is happening here?

problem screenshot Hi. I am using 120.0 last version firefox, Windows 11 also last build

When i open normal tab with Yandex search and search something, i get yandex captcha every time

When i open private tab firefox (also waterfox\librefox), i get captcha every search google.com. Change proxy with FoxyProxy fixing problem

Google chrome \ vivaldi \edge \ yandex browser and other chromium browsers doesnt have this problem

How do I paste in the game forge of empires thread windows with my mouse and without clipboard keyboard options in firefox, it will only allow me to use clipboard control V for keyboard not my mouse, using my mouse to select all, copy, it's fine, cannot use paste with mouse, only in browser search bar, i do a lot of pasteing or i would not ask, it works with a diff browser, Firefox is the best for gameing,

It has reinstalled all my other extentions, but hasn't my password manager for some reason. Or at least I can't find it. I also can't remember the name of it, and so don't know what to search to download it again. Is there a way to see historic extentions or something?

Hello all. I'd like to restore the backspace button function but the previously workable solution — resetting browser. backspace_action to 0 — is not working for me. Any hints as to why that might be the case?

Themes do not stay locked since several updates back. It is ridiculous that every time you open the browser you need to go to settings and get 'dark theme' back on, when it is the only theme many of us with visual problems can use. MANY people have complained about this (read your own reviews). FIX IT! It's doubtless a five minute job to put this back the way it was.

I'm trying to load https://bfjoy.com/ and only Firefox is redirecting my typing of 'bfjoy.com' as an http: website instead of the correct https:

Why is this? I assume DNS but what is Firefox doing to redirect to the unsecured site that other browsers aren't?
