In one of the most inept decisions ever, Canonical say you must use the browser you originally signed up to Launchpad with if you lost/can't remember your password! Why????
It just seems really stupid! I signed up with Chrome, but have since ditched it - for my own security reasons - and now use Firefox. Yet, because I've changed and forgotten my password to launchpad, I can't change it just because I'm using Firefox. Surely this is sheer, outright lunacy?!
I'm not going to reinstall Chrome, so that leaves me with no choice other than to re-sign up with a new launchpad account, or flag launchpad altogether in protest... I'm not going to sign up again anytime soon - they can change their stupid rules. Their loss.
