Somebody suggests me that “killer apps” are not really meant to kill.

Point well taken. (David even drew this little cartoon about it)

He’s referring to the fact that Piggy Bank takes a while to start the first time you restart your Firefox after having installed it, and people think it’s stuck and kill it. When that happens, their profiles become corrupted and nothing works as before.

Ryan has written a blog post on how to get your firefox back if profile corruption happens (no worries, no data gets lost, it’s just firefox that doesn’t have the ability to roll back to a previous profile if the installation of new extensions doesn’t go well, hopefully they will fix this part soon).

We apologize for the inconvenience (and we’ll make sure to profile the startup time or find a way to provide useful visual feedback), but at least now we know where the problems are.
