Just got it - runs really fast, esp. loading & page rendering.

Not sure about RAM usage though - VG currently using around 90MB.

Nice to see basically all my plugins still work - including FireFTP, and the obvious ones (NoScript & AdBlocker).

already did foo

5m soon - http://www.spreadfirefox.com/en-US/worldrecord

had major issues with vBulletin boards, AVG/Realplayer plugins (i disabled plugin compatibility checker anyway)

loads faster but too many issues at the moment imo - going back to FF2 for now

i did not note any problems with vbulletin,  maybe its the special version of the vbulletin or the site specific skin thats causing the problems.

overall i'm quite happy, memory usage difference is really noticable when you have multiple tabs open , and the new adress bar is very nice, most other changes are not that visible.
