I have written a rant about Mozilla a couple of months ago that I still think is relevant: https://blog.r3bl.me/en/mozilla-dissatisfaction/
Although I'm all up for supporting free and open source software, the situation with Mozilla has became shady enough that I just want to move away from it. Unfortunately, I have nowhere to go. Midori is still not completely usable, I just can't convince myself to switch to Chrome or Chromium because I genuinely feel uncomfortable using them, IE/Edge are only available on Windows so they're practically useless to me, Firefox forks are really nothing groundbreaking, Vivaldi is not open source...
