I know Firefox used to be my main browser, but I didn't like how they drew the long knives for Brendan Eich (and I used to support gay marriage back then, I've since come to regret that support) so I dropped them. They are simply on my computer for if and when Brave won't do what I need. But since they released Brave 2, it's become stable and reliable so I've not really had to use another browser.
I did use Dissenter for a while, but it doesn't self update, and they don't update it all that often, so it just doesn't feel safe. The only real advantage it has over Brave is sometimes YouTube ad will slip past Brave somehow, that never happened on Dissenter. And on Brave I have to run the Dissenter app in developer mode, and it asks me every time I start it up to turn it off, and I'm like, no. On Dissenter, the app is built right into the browser.
But it's not worth it, plus on Dissenter you get messages all the time saying it failed to update, every few weeks, and the only way stop it is to uninstall and reinstall, but it will happen again in a few weeks.
