I was pulling my hair on more than one occasion. What was that darn PASSWORD?/?. It really sucks when the browser stores all the psw log ins and they get erased. With several dozen sites, emails and passwords to track it is hard to remember all.
I try to have a similar psw/log ins such as changing CapitoL letters and switch numbers around but storing them somewhere helps.
I used Roboform before and its helpful, now I have small self encrypted .txt file + the browser stores log ins. FireFox is best even Comodo and IE can store log ins.
