Hi all, I'm new here, but I used firefox portable since months ago...
In our company, we use a frozen version of firefox to maintain java and flash.
I've been testing portable firefox (same version, ESR 52.9) for a while, and found one problem when, inside portable firefox, I try to open and eml file...
It's say that Thunderbird is already open, I must close it before open this attachment. Same message when trying to open a second instance of portable Firefox (but this is not the problem). Thunderbird in our computers, is not portable.
