Firefox has gotten much better; especially in terms of memory usage. I switched to it at work on Windows and haven’t looked back. But the reason I was open to revisiting Firefox was a desire to want to escape Chrome. And I spent my first few hours with Firefox making it behave like Chrome, which wasn’t hard at all.
So yeah. Try Firefox because it’s not Chrome but stay with it because it’s good.
