Chromium is the best browser to use on Fedora, for several reasons. It is zippier than Firefox and Vivaldi.
sudo dnf install chromium -y
Install libraries to get H.264 and other video formats to render correctly (Make YouTube work flawlessly).
sudo dnf install chromium-libs-media-freeworld
I switched to Chromium after being a Firefox user for a long time before the transition I was switching between Vivaldi and Firefox.
Firefox turns sluggish after reaching a certain number of tabs, and at a point, it would not clear cache even if the development tools were open.
Vivaldi would have lag and turn sluggish to render pages and the default animation felt very sluggish once I had more than eight tabs open.
