Hello, indeed with Firefox, I still have a problem playing YouTube videos with higher qualities. This limits it to 1080p. With other browsers (edge or opera) for the same video other resolutions are offered such as 1440p and 2160p, which Firefox does...
Tabs
It's a shame that there is no function to group tabs by theme in the tab bar. The only browser to do this is opera with the tab island function. Finding this in Firefox would be a positive point for anyone who opens a large number of tabs.
