Class Attribute Details

.running=(value) ⇒ Object (writeonly)

"is firefox running" is a question about the machine, not about a profile, so a config naming three profiles asked pgrep three times - a fork each, and the slowest single thing booker did on that config

Class Method Details

.reset! ⇒ Object
