Firefox Community Forum

I don't know why or if it's related to Firefox, but For the last couple of weeks after logging into Instagram or Facebook or Disney+ or Paramount+ or X I get an email from them that says I logged in from a device I don't usually use. I have had the same device for several years. Getting those emails is annoying and also concerning. Can I fix this somehow? FYI I use Duck Duck Go via Firefox for my internet searches.

I switched back to release from nightly because the themes support completely broke rendering of menus, buttons, etc on various (read: pretty much every single one, including this one) websites, making them difficult or impossible to use. I've tried a browser refresh to no effect.

unfortunately, it appears the feature has been rolled out to release now as well, as pictured below.

I've tried cycling through themes, setting custom colors and forcing it to never replace the website's specified colors etc, turning off acceleration... none of it works. this is an issue on my desktop, laptop, and tablet (surface pro x), basically every platform I use except mobile.

any ideas how to fix this? it's really annoying and I'd really like to not hop browsers again, I've been using firefox for a good long while now.

I am currently on windows 11 for ARM (surface laptop 7) and this problem is occurring with both Firefox as well as Firefox developer edition. It's also only happening on my external monitor. I have done some searching and found posts from as long as 4 years ago. The posted solution is to disable any compatibility options but in my case none are selected. This is driving me nuts, does anyone know of a solution? This has to be firefox specific because no other program does this, including other browsers. I have included a screenshot to show what it looks like.
