Nice to find a companion from old Windows 7 that also denied the step to W10 😀
As for browsers, there are a bunch of good ones, lateley it depends on your taste which one to choose.
I started to search alternatives that provide cloud bookmark management from scratch, because I still use Windows 7 and 2-3 other Linux distributions. This way will make sure I always have the same base of information at hand, whatever system I'm on.
I found one Russian based 'Yandex Browser', equipped with cloud bookmark management and surprisingly good support, but unfortunately I was not able to find it for Solus right now, so I only use it on ArcoLinux and Manjaro.
Vivaldi was already known from Windows and matured over the years, so I gave it a try. The UI is clean, nice and adjustable, it offers cloud bookmark managament and works without major issues so far. Updates every now and then provide more features. The bookmark system is a bit unique, but I managed to adopt me to it.
From third party tab you can install Google Chrome, but I'm not sure how your data is opened to the company.
The Brave browser seems new, fast and lightweighted, but I didn't test it too much either.
Opera is ok, but others offered more to me.
Tor is Tor and therefore has it's own target group.
Your choice!
