When I try to log into Xfinity to pay my bill I get this. Is it related to Firefox? Thought I'd ask you before I tried to work my way to a human at Xfinity

I keep getting this message when I try to sign in on Firefox. Chrome let's me sign on but i much prefer Firefox. Any suggestion? {

I am trying to organise my Firefox bookmarks into folders on my Mac Studio. However, when I try to use the highly-touted "just drag and drop advice" it does not work. It doesn't work in the drop down and it doesn't work in the bookmarks manager. Drag and drop functionality works elsewhere on my Mac just fine.

Note, if I open every single bookmark, click on the blue star, then re-assign the folder it does work. However, that it a mighty pain in the arse.

Since I know it will be asked...'yes' both Firefox and my MacOS are up-to-date. And 'no' I haven't upgraded to Tahoe.

I would appreciate any help that anyone can offer. Thanks!

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

Unlike before, many sites that I visit regularly, I am now having to log in every time I visit, including support.mozilla.org.

Did I unknowingly change something, some setting? or perhaps it's due to an addon?

I'm so frustrated! I don't have time for this... I try to use my pw, it gets rejected. I hit "Forgot pw". I get confirmation code. I use confirmation code. I use computer-generated pw and Moz saves it. I try to log in again and pw gets rejected.

I am trying to get to my account to find out why the VPN I've been paying for for years is not active.

iOS 26.1 on an iPhone SE; Google Maps 25.47.0. Links to apps don't open in-app. If I click a Google Maps link, it sends me to the App Store. If I click a link to Instagram, it sends me to the App Store. But I already have those apps! How do I make it work like it used to?

In Settings>General>Language, why is there an option to "Use your operating system settings for “English (Zimbabwe)” to format dates, times, numbers, and measurements." . I can't find any documentation for this. Is there an interesting 'Zimbabwe' format or feature? If so, what is it?

Do I need to add an email filter?

I just bought new PC and switched to win11(never happened on win10). Videos stutter when on 2nd monitor and game is open on first, but audio doesn't. Problem goes away immediately when clicking to the firefox window. Happens on both youtube and twitch, but not on Nebula.tv and not on chrome. Doesn't happen if the video is 480p, but does on 720 and 1080 and both of them are 60fps which might be something. Also doesn't happen if the game is windowed, but does on fullscreen and borderless.

I've disabled hardware acceleration (in windows and browser). I've tried setting both monitors to 60hz, setting firefox priority to high (and game to low), disabling effiency mode, setting power mode to performance and tried a lot of other things including about:config settings. Also ruled out extensions.
