It was reported a decade ago.
But we are only "users", even if each if us converted 10 or more IE6 users and bothered IT departments to allow Firefox, web sites to write for web standards and not IE etc etc.
When they ask for money, we are "valued community members". When we have a question we are just annoying "users" it seems.
And the worst part: if you donate to Mozilla it doesn't go to Firefox. It goes to some other project.
Because Firefox is a profit center for Mozilla and they are milking it dry year after year and our donations comes on top of that.
Still I use Firefox. It is still better for my purposes (large hierarchies of related pages that lives from hours to weeks).
And it is not like using Google Chrome would improve the situation.
But lately (maybe the last twelve months?) I have started to use LibreWolf too. I use it as my research browser while using Firefox for all logged in work. It feels good, like using Firefox back in the days.
And if I can work against both Mozilla and Google simultaneously, maybe I should cut Firefox completely :-]
