How To Manually Download and Install FireFox Extensions.

Never had the course to get Firefox extensions manually installed until yesterday when I had to get a PC that wasn’t connected to the internet up and running with my fave Firefox extensions. On a normal day the Add to Firefox button does the job:





But since this particular desktop pc wasn’t hooked up to the net, I needed a way to get the extension files off the net and then manually Add [it] on to Firefox.

So how do you go about doing this? How do you manually download and install Firefox add ons?

Simple.

Browse to the Firefox add on pages, instead of left clicking on the Add Firefox button, right click on it and click on save link…






file extension should be ".xpi"
Once the file is saved, to do a manual install of the extension, Start Firefox and drag the downloaded file unto it. Capish! You will then be prompted to continue or cancel the installation. That’s all.

Another alternative to getting the extension files off the net is to browse to the Firefox add on pages using a browser other than Firefox.



This will automatically turn the add to Firefox button you normally get into a download button. You can thus easily download the extension files.
