For some weeks now I have been having problems with both Firefox and Thunderbird. Neither will load. Sometimes I have been able to load once after a clean reinstall. I have tried: virus scanning and cleaning portable version on different computers (I use a portable version whenever possible but this has become an issue on static computers also) deletion of data folder

Just to rub salt in the wound, when the programs crash and I try to send a report, the error reporter says it is unable to send a report. Have not had time/patience to look into that.
