I have an old Lenovo IdeaPad with fairly modest hardware, and I have both Fedora and Windows installed. About 90% of the time I use Fedora, and it works fine overall. The only thing that bothers me is that Firefox on Fedora feels noticeably more sluggish compared to Edge or Firefox on Windows. Maybe it’s just a perception issue, but I’d love to know what others are using as their web browser on Linux.

Edge is based on Chromium. I'd test any Chromium based browsers (Chrome, Brave, Vivaldi, etc) to see if performance is better.
