I have been experiencing some troubles installing Firefox add-ons after updating to the latest version of Firefox and was not able to find out why the following is happening when installing add-ons. I sometimes receive download errors after accepting the installation which sometimes work after repeated attempts but sometimes fails all the time.
As I said I was not able to find a solution for this other than to download the Firefox add-on to my hard disk and install it from there. The xpi files can be downloaded like any other file by right-clicking it and selecting the Save As entry in the menu.
The installation from the hard disk is pretty straightforward once you know where you can start it. It can actually be started in the File > Open File menu. Just located the xpi file that you have downloaded previously and the installation will start automatically. There is no security barrier that is normally asking to allow installations of Firefox add-ons from a website.
