I've been a long term user of Chrome. Ever since it was released really. But the whole DRM thing is alarming and last month I migrated back to Firefox. It also led me to migrating my emails to somewhere else. I'm now looking at other services but wow does it make you realise just how much I rely on Google. Partially with an android phone.
Oh I also switched to duckduckgo from Google and can't see a downgrade in search results.
Honestly. If you're going to move your email then think about using an alias service first or as part of the move. That way it's so much easier to move your mailbox in the future. You also get better spam protection when you create an alias for each site. Luckily I had already invested in changing all my services to use their own email alias and pointed them to Gmail. When looking for a new mailbox provider I was receiving mail going to multiple mailboxes. Once I was happy I went down to one service and ditched the others.
Personally. I went with SimpleLogin and my own domain name. I ended up with 300 aliases. Yes that took a long time to go around updating websites! I also use Bitwarden which I used to generate the aliases using my API key from SimpleLogin.
mix-up the ui a bit so users don't notice them building search into the browser ui and out of the reach of tracker and ad blockers. same idea as edge's default start page that's basically a mirror of msn, except you can't block ads on it because it's baked-in.
