You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !technology@lemmy.world
This is a most excellent place for technology news and articles.
For Search I use Duckduckgo (free).
For Mail, Calendar and Contacts I use Fastmail (free or paid, I use the paid version).
For file storage there’s plenty of alternatives (Dropbox etc.)
For browser I use Edge, but it is also built on Chromium. I will make my choice once the recent Web Environment Integrity topic has become more clear.
Why do you use Edge over Firefox?
