From two hours seems Firefox lost all saved access to my favourite sites, forums and so on... Checking saved ones I found my new enemy: Lockwise... It wants me to set a principal password (which I never had before), so patiently I followed instruction to set ANOTHER USELESS password I will forget in 10 minutes... but... Once I type a safe password, and confirm this password, an annoying message pop-up and tell me that: "Impossible to change the password"... @#!"$)(%R?!" I never had it, why would you change it? You have to set it? Why it doesn't do it? Note: I already have a Firefox account and, yes, I made login, and Yes! Sync is working properly, I can login and see saved accesses on my mobile. MOREOVER: every few minutes I have a despicable pop-up which requires me to set THAT password! And if I try, it tells me it's impossible to set! AAAAAAAAAAAAARRRRRRRRRRRRRRRGGGGhhhhh! Thanks to who can help... I'm going to launch something through the window... >_> Mech.
