I'm encountering some UI errors with the last couple updates. With an update from a couple weeks ago, I noticed when viewing PDFs in the browser, random characters would be invisible, and in Google Sheets I'd notice some cells appeared blank, though selecting them showed that there was text inside. I also noticed disappearing text in a Google Doc I was working on. Now with the update that was just released today (154.0) all PDFs, and entire screens in Sheets and Docs, and other random graphic elements, are showing up as just flat black (see attached screenshot). My job involves working with spreadsheets and PDFs a lot so this is severely impacting my workflow, and I am reluctantly working in a different browser today.

I did a browser refresh, and then I uninstalled and re-installed, and that didn't help anything. What should I try next?

I should note I am using Firefox on Windows 11. I am not experiencing any issues with Firefox on iOS or Mac OS.

Edit: I was able to troubleshoot and fix this by disabling hardware acceleration under performance settings. Problem solved!

Since yesterday, I have been trying to access www.old.reddit.com - which I have been using for 15 years and is a much better version than the new one they introduced several years ago, reddit.com?

I keep getting "The page isn’t redirecting properly

Firefox can’t connect to the server at old.reddit.com"

What is going on?

I have had a bit of a problem with a keyboard today and tried downloading drivers and reading faqs about it, and apparently as of today (august 20th 2026) firefox decided that most sites are unreachable (which they clearly are since the laptop running win11 works) Why the sudden overstep? BTW I can't access this page on the win10 computer.
