I always use Firefox, but there is one annoying thing they do not seem able to fix: The debugger. It often happens to me, that I can step through code, but I simply cannot see the value of variables at all, not by hovering, not by adding them to watched variables. This often happens when working on JupyterLab. And some days it works suddenly. Maybe JupyterLab has become so overheady, that the debugger gives up or something. No idea. When it does not work, I just use GNU Guix as follows:

guix shell ungoogled-chromium -- chromium

(a double minus there)

That runs an instance of ungoogled Chromium without me having to install it in the system packages or so. After the first time the build should be cached until you update your Guix packages and start up quite quickly.
