I’ve used it somewhat occasionally, and to me it seemed like Chrome as far as memory usage and sluggishness with multiple tabs and windows are concerned. But I like the fact that it comes with a built-in ad blocker, and avoids contacting Google (unlike Chrome). This announcement says it should perform better, and that’s something I’d like to try out and see.

If you were frustrated by the recent “signing in” changes and the backtracking of that in Chrome, you should try Firefox and Brave.
