I haven't been using Firefox long but have added FVD speed dial and a couple of other things and I find that, if I click on a link in an email or something a plain version of Firefox opens, without any extensions etc. if the normal version isn't already running. Is there any way to get my usual version to open from links? I don't know if it makes any difference but I did switch to a portable version from the normal install as I run an SSD as a primary drive and couldn't get enough control over file placement with the normal install version and didn't notice if this happened before I changed over.
