Two days ago, LW started behaving very oddly. It suddenly stopped rendering pages - but only on some sites. For example, the default Lemmy skin is fine but the Alexandrite skin is not. The BBC website doesn't work either. A few others seemingly totally random.
The domain resolves and it makes the initial connection and then it takes up to a minute of doing nothing and then just craps out, unable to render the page. Checking the Inspector reveals no errors or warnings and the network inspector is making a connection but not loading anything other than headers and basic tags.
The page presents no errors it just shows a blank screen. <html> <head> and <body> tags load but nothing else.
All these pages work fine in all other browsers I've tested in (floorp, Mullvad, vanilla FFox and Brave).
Details: LibreWolf 128.0-2 (flatpak) on LMDE (Faye).
Any clues, pointers or advice very gratefully received. I love the browser and have it set up just how I like it so don't really want to switch to another.
Could be yeah. Very weird how it just started happening though. As far as I'm aware nothing on the websites has changed and I haven't updated LW in the last week or so.
