I am excited to try out the new build with the memory leak
fix, but I am not interested in running firefox's beta.

does that mean i have to wait for mozilla to make a new
production release?

for some reason i got the sense that piggybank is having a
problem with the firefox auto-update. this is probably a
misread by me, but just in case... in general, i think that
"versions" are a 20th century concept. at least, they have
very little place in a web2.0 world. i'm fine with having
two branches, but after choosing wether i want the
production or the developer branch, i want my web2.0
software to take care of staying on the freshest available
prod/dev version. every day, i should have new features to
greet me
