I'm trying to download add-ons to Firefox and I keep getting download error -228. One way round it is to right click on the link to the add-on and save it to my desktop and then open it from there. However these files should be xpi files I'm told and when I try to download them they seem to be htm files. I've been advised to check the content of these files for errors but I don't know how to do this. Anyone help?
P.S. I've tried virtually everything in the Firefox Knowledge Base.
