I downloaded Ubuntu-Mate 20.04 after some time of not using PC at all, I only used a android tablet on traveling. Ubuntu-Mate 20.04 is very good. I would use Vivaldi as a default browser, but it uses a lot of cpu! The fan goes full speed, I don't like the noise. So I tried Firefox that is included in Ubuntu-Mate, cpu fall to 25% and fan stop completely.
Bad sentences:
Surprise to me, but I am happy with Ubuntu-Mate 20.04 and Firefox.
Try again:
Vivaldi and high cpu usages was a surprise to me, but I am happy with Ubuntu-Mate 20.04 and Firefox.
