I 100% agree. I don't mind design refreshes. I think I'm in the minority of loving the current Firefox logo.
But this just sucks. They really took their unique, clever wordmark logo (but still very modern and minimal!) and replaced it with a bland, trendy 2022 typeface.
I know this is super petty, but this might convince me to find another password manager and method for syncing tabs. Might try librewolf, too. Rebranding invites users to re-evaluate their view on a brand, and mine isn't changing for the better.
