Twitter's login page won't load when I try to open it in Firefox. https://twitter.com/ https://twitter.com/ loads just fine, account pages like https://twitter.com/firefox load just fine, and individual tweets individual tweets load just fine. But when I click the login button on any working page, or go directly to the login page at https://twitter.com/i/flow/login, all I get is a white rectangle in the middle of the screen that flashes a loading-spinner for a few frames every two seconds but never actually loads any page content.

I can log in just fine in Chrome, so the problem is specific to Firefox. The problem started at least a week ago, but I don't log in on my desktop regularly enough to know exactly when the problem started.

I turned my Browser Privacy setting to "Standard" and cleared all site data from Twitter, with no effect. I use uBlock Origin, but the problem persists when I disable it. The problem also occurs in Private windows.

I have Thunderbird as my client on my primary home workstation as well as my traveling laptop. Each instance is configured exactly the same with regards to the four servers I use: Earthlink, GMail, Outlook and GMX. Each of those server/services is also identically configured with regards to these Server Settings: Leave Messages on the Server Until I Delete Them.

Each of the servers -- except GMail -- has the same behavior with regards to how it handles things when I click on the option to Get Messages, i.e., each server seems to be able to identify which of the clients has and which of the clients has not previously been served up with a newly arrived email. It will not send the same email to the same client more than once.

GMail is the exception. There I get what seems to be a first-come-first-served protocol. If I perform Get Messages on the laptop, I will get the email, but will not be able to get the email when I subsequently make the request from the workstation's Thunderbird instance. [Or, if the first request is made from the workstation instance, the laptop instance will never get the email.]

I realize that my usage pattern is rather unique, so it may well be that no one else has ever experienced this behavior, but if anyone has -- with regards to any email server, not just GMail -- and knows a work-around, I would appreciate the instruction.

And, in anticipation of one line of questioning, when I say that all four server/services are configured the same, I am indicating that I do work with GMail as a POP3 server, not IMAP. All my email content ultimately resides on my own hardware resources and is only temporarily resident on hardware provided by the server/service entity.

Hi folks, So my university uses gmail and accesses with Duo Mobile. I usually use Firefox on a Win11 PC, no problem. This morning for some reason firefox will not let me even begin the login process. Chrome works fine. I have disabled four extensions (DuckDuckGoprivacy, Unpaywall, YoutubeNonstop, Boomerang) and restarted, no change.

Screenshot shows errormessage on Firefox, with functional Chrome screen in background.

This has to be a firefox issue? help please!

Hi,

I'm trying to remove the bar at the top of firefox browser with tabs in them. I read another article (https://support.mozilla.org/es/questions/1417387#answer-1588947) under spain link, i think, and the solution said to write "TabsToolbar-customization-target { visibility: collapse !important; }" somewhere. Where do I go to write that?

I tried the console by pressing f12, but that doesn't seem like that's it. In that article it also mentions to go to about:config and change the status of "browser.tabs.drawInTitlebar" to false, or delete it, but didn't work either.

I'm not very good at English, so I use a translator. After updating to the latest version of Firefox, the problem I'm having is that when I play a YouTube video on the web side, the playback box will have a large white colour, as shown in the red box below. I would like to know what is causing this, my current version is 123.0
