I don't do webdev, so I can't really comment about that. I agree wrt edge being terrible and not being willing to pay Apple prices.
Anyway I switched to Firefox on my computers and mobile system. I use that VPN to try limit Google's tracking of me and I use duckduckgo for the same reason.
Long story short I just switched back to chrome on my Android, because Firefox has kinda stopped working. I used to be able to keep 100 tabs open, not I can't even keep 1 open in the background. When I go back it just forgets what it was and won't refresh. I click refresh and it shows it's refreshing, but then nothing happens.
Nothing I can do. I'm reading some or I see a great article and I open it right away in a FF tab for later. I go back it doesn't load. Then I can't reset/restart it, because it won't die and then it stops syncing, etc.
It's really really bad. Sadly this wasn't the case when I decided to switch about 8 months back, this is only in the last 60 days.
I'll keep using Firefox for now on my desktop, but honestly I really rely on profiles and sync across profiles, which is a pain to get around on FF as it is, but now it's a big burden I can't really see my way around.
Too bad, but honestly I need a reliable tool more than I need privacy at this stage.
* Uses 30-40% CPU constantly on my Ubuntu laptop, causing the entire system to freeze.
* Slow on JS-heavy apps like JIRA, Gmail, Google docs.
* Firefox Android randomly decides to stop loading web pages, requiring a force quit and restart.
* Firefox Android bugged out while writing this comment, the text I typed would appear at a specific location, regardless of where I put the cursor. This and various other HTML input bugs require me to restart the browser again and again.
