All my bookmarks, search history, browsing history (so I can type a portion of a URL into my address bar, say a word or so, and have it find the page I want even though my own memory fails me), that sort of thing. Plus it works across all my devices.

And casting pages or my desktop or such to my Chromecast is really handy too, and so is the Chrome Remote Desktop feature that I use sometimes to remote in to my PC. I don't know how many of those things Firefox has, maybe it casts and stuff too.

But yeah I use all that kinda stuff, and of course it keeps me logged in to all the Google services I use, like my emails, YouTube, Drive, Docs, Maps, etc, and facilitates using that stuff seamlessly without issues, which is great.

I'm deep in the Google ecosystem basically, and I'd be happy to switch browsers just so long as that deep functionality remained, know what I mean?

Some people here really hate Google (like, specifically on Lemmy people seem unusually angry about them existing), but they seem no worse (or better) than any of the other companies that offer all this stuff, so I might as well pick my poison as it were. They're all evil at the end of the day, haha.

Sure, I could run 20 different individual open source services on a server to do everything I use Google for, albeit without integrations and likely a bit more muddled and less feature complete, requiring ongoing care and upkeep, and that IS kinda appealing, I do get why, I used to do the homelab/home-sysadmin stuff for fun, but I just don't have the time or patience to do that stuff these days, you know?

I got older, and now I just want a functioning service that I don't need to fiddle around with these days, and that way of life extends to my browser too. Give me a good browser that lets me do what I want with all the integrations I like, and I'm happy.

Right now I'm not happy with Chrome because of their ad blocker policy, and how locked down plugins are in general. And I want to theme it! Firefox used to let you change everything in a themed all the colours, icons, element sizes and so on, it was dope. I assume they still do that, I'd love that.

Anyway, I hope that answers your question :-) Sorry if it is a bit muddled, I blame ADHD brain :-P
