Laptop became horribly slow online. Tests suggested Firefox corruption. R/R to current version. Two mailboxes (one each) are retained as the last ones in use. All others are lost in transition. Gmail and Yahoo do not recognize my new Firefox settings beyond the two saved accounts. I have multiple accounts for various uses. I'd like to recover them but there is no evident process for this. Also, the same thing has occurred for all saved passwords (expected) so I have re-saved many of them. However, LinkedIn, Ebay, PayPal, Twitter, etc... not recognized. Email systems say lost accounts don't exist while member accounts remain locked to lost email accounts. I appreciate your solutions or, if necessary, suggestions, -- such as useful direct contacts for Gmail and Yahoo support. Thanks, -- Ed
