User:FL Guy

My suggestions for top priorities (my $ .02, for what it's worth)

1) Fix the extension compatibility scheme. I do understand the intent of the existing system, and the responsibly of extension developers in it, however it simply isn't working well. As evidence, I offer the flurry of user problems/activity after every release when the majority of the extensions no longer work.

2) A MUCH slimmer footprint - with today's basic features. 225 MB with just 3 tabs open is simply too much.

These are by FAR the top priorities in my mind, above and before any additional features. Without these being resolved, FF's growth will likely stall/regress (imho of course :-).

After that,

3) The ability for each user to create, save, install, and manage "feature (extension) sets".
