Je vais copier un commentaire de HN qui résume très bien ma position:
In terms of open source there are really only Chromium- and Firefox-derived browsers (I’m disregarding projects like the still pre-alpha Ladybird here). With Chromium browsers, you’re still subject to Google’s whims in the long term, such as removal of V3 extension support. (I.e. a conceivable fork with V3 compatibility will inevitably become too difficult to keep up to date with the mainline.) If Mozilla dies, Firefox and derivatives will in all likelihood wither away as well. IMO there is no alternative to supporting Mozilla, and also keeping them accountable and criticizing them where criticism is due. They are still roughly the good guys, even if sometimes misguided.
The topic of Firefox and ads is nothing new:

One alternative recommended by the present article, Brave, is dabbling in ads as well: https://brave.com/brave-ads/
