Yahoo mail continues to crash ( since FF updates to current one , began back in 36) and hangs, and when I go to type a draft, it will NOT autofill from contacts list. I know this is NOT a yahoo problem, because if I use Chrome, it does fine. I safe mode tested, and determined that ad block plus is the culprit at least to the contacts not auto filling. I cannot keep ad block plus off, or it allows way to much garbage including yahoo mail ads(so annoying) and I cannot find any solution on the adblock plus homepage, but I am certain there must be a filter or script that can be added to ad block plus to solve the auto fill contacts situation, however, Mozilla needs to tell us what to do about the problems with the crashing ( since updating) every time we go to use yahoo mail, and clearly this is happening to lots of people, as i see many other posts related to this in this and other forums. so does anyone know how to fix this without giving up the blocking of bad ads etc..????
