We lost firefox and thunderbird connection. Thunderbird is ok again. I have tried several times to download Firefox again but alwyas get the same message : Firefox cannot create lolder archive. I have tried to download several different versions: 32 and 62 bits with and without extension MSI and several different numbers like 82 ; 85 ... I never used a pasword so I don't have one. I noticed that without a password I can reconnect but will lose information like websites.
