I did not see your post, I went to Mozzaline and saw two separate posts saying RC2 & RC3. I would thing that RC 3 maybe final as there was an entire week between 1 & 2. So you are right. I am starting to have some concerns about Firefox but time will tell. I t is kind of hard with all the changes MS is making, now there are Moments???

When I find it.
ver110.0.1 - is the most recent main release.

ver111.07b - is the 7th beta release of 111.0 for testing which will later become the Main release.

I don't use "nightly" so i'm not sure what they're up to.
