As a long-time Chrom(e|ium) user, switching to Firefox this week was painless (+uBlock Origin to match Brave-like defaults).
@roy makes a good case for switching going into 2024:

There was one snag that folks should be aware of: Firefox "suggestions" send your URL bar input to Mozilla and/or your configured search engine. It was easy to disable, but felt shady given that it leaks your search input to two external parties by default.
