I use Firefox, but at the same time I have Vivaldi installed for PWA, like for mbin right now. Why Firefox removed SSB is beyond me, was like one of the things I used regularly. Being able to pin my Mastodon account to the KDE taskbar and click it to pop it open in it’s own window is something I really don’t want to do without.
Are you perhaps looking for something like this? Or something else.
That said, learning the terminal commands is a much better path. You’ll develop a richer understanding of the various tools with repetition.
