I wrote that i talked to the devs directly? I also wrote that i have followed the issues for years. What makes you think this is the last resort?

This issue is all over the place.

I will admit it was too harshly written, the issues seems to only be on the osx platform and Firefox is great on all other platforms, but the issue has been detailed in their own tracker and subreddit for many years.
