I've found two major roadblocks when switching browsers:
1. Migrating your passwords, 2. Migrating the bookmarks.
If you use an external password manager (Bitwarden, 1Password, even KeePassXC) and an external bookmark manager (Raindrop is excellent, Pocket is barely usable) then switching browsers becomes very easy – to the point where you could switch to a new one every month if you wanted. The browser is no longer a place where you store your stuff, it just becomes a UI to browse the internet.
