What makes you think I do not use (something like) Firefox? I use Fennec - F-Droid's build of Firefox Nightly - as my main browser. I only use Chromium-derivative browsers for those sites which won't work with Gecko and to test whether things I make work 'on the other side´.

As to not trusting an NGO with my data, well... where to start? Ever since Mitchell Baker turned Mozilla into an activist cooperative while firing those pesky developers - who needs developers when all you want to do is political campaigning - and raising her own salary 5-fold that organisation has lost its shine as far as I'm concerned. As far as I'm concerned Mozilla is ripe for a new 'March 31 event' [1] in the sense of a transfer of the stewardship of the Gecko engine and Firefox browser to either another organisation entirely or to a splinter group from within Mozilla which still considers developing the main competitor to the Blink engine as its primary focus without any of the heavy political baggage from the Baker days.
