Oh Firefox, the best of the worst browsers, as there are no new and exciting browsers any more. Added new unremovable extensions button, video conferencing support is still flaky, but I use it daily, no matter what. Maybe one day Andreas Kling's browser Ladybird will replace it...
I switched to Vivaldi for most of my browsing. I was a Firefox users for over a decade, but had to quit after they kept rearranging the UI every six months.
Vivaldi isn't perfect. It takes a lot of searching around the internet to find out how to enable or disable certain options (and there are a lot of them), but right now I consider it the best of the worst for 2023. It's the most customizable, and the browser sync feature works pretty well.
