I’m on a Mac. After the Mozilla mess about a month ago I went back to Safari from FF.
Not nearly the add- ons available.
I like FF better than Safari and T’bird waay better than Mail.
Guess I’ll have to grudgingly go back to FF.
IIRC Pale Moon is PC only.
Yes, your memory is correct.
For what it's worth, here's my take... The 'guts' of FireFox (which are the same 'guts' in PaleMoon and some others) is open source and as such is not explicitly a Mozilla Corp. product. And since I block google analytics and other such counters with NoScript, it makes it harder (but of course not impossible) for those 'hit statistic' followers to know what I;m doing on their sites. Yes, FF reports that it is in use, but overall statistics from my machine are skewed, so Moz is not getting an accurate 'hit count' which may or may not affect any monitizations they may accrue. This machine and my Linux box have FF, my two laptops run PaleMoon.
There may be some other FF clone using the Gecko engine that is available for Mac, but I can't help you with that. There is something called Aurora available for Mac, but it uses the Webkit engine (same as Safari) so it seems like it wouldn't be a change..
