I know we aren't allowed to use Chrome. We can't use Brave. But how does the Lemmy community feel about the Vivaldi Browser? or is it still not Firefox...
Use whatever you want. But do consider if you want to contribute to Google's monopoly, and if you want to use an open-source browser.
Vivaldi Browser is not open source. Better use Brave than that…
If you still really hate Firefox, Ungoogled Chromium which is basically Chrome with all the Google stuff removed.
All of the above do still contribute to Google's monopoly, so I would really encourage Firefox or a fork.
Barring that, you could also get away with a WebKit browser (like GNOME web, Nyxt). Although WebKit is developed by Apple, it's still open source and doesn't look particularly bad. If you're on a Mac, Safari is an option, but it's closed source.
Use whatever you want. But do consider if you want to contribute to Google's monopoly, and if you want to use an open-source browser.
