Just took the plunge into FF 4 RC1 and it was a breeze. All my add-ons and customizations including Extentions, appearance, and plugins are there and functional. It appears to have over-layed the 3.6.15 without a glitch...Good job Mozilla, this is why I like this product...great developers and outstanding product quality.
Easiest FF upgrade ever. Hope the final is as easy.
