How to install Firefox plug-ins?

by Derek Firth / July 20, 2006 9:54 PM PDT

I have downloaded a lot of plug-ins & extentions for Firefox with most of them having .xpi extention. How do I install them & where so that I can start using them?

Firefox extensions...
by John.Wilkinson / July 21, 2006 3:47 AM PDT

Here you have two options:

1.) If you simply click on a link to an (.xpi) extension using Firefox it should automatically display a window that counts down for 5 seconds and then asks you if you want to install it or not.

2.) If you downloaded it elsewhere, downloaded it using another browser, or downloaded it by right-clicking the link and using Save As, you can still install it easily. Just go File->Open File, browse for the xpi file, and open it. You should then receive the same window described above.

Now, at any time you can find out what extensions are installed, modify their settings (if applicable), and disable or uninstall them by going Tools->Extensions.

Hope this helps,

One more way

There is also the method of dragging a downloaded .XPI into the Firefox browser window (or the Extension Manager window). This opens the dialogue box for installing the extension. Themes can be similarly installed by dragging the .JAR into the Theme Manager box. Not any better than the other methods mentioned but just another way.

One thing possibly worth a mention with this method. If Firefox is being run within the protected environment of a sandbox (Sandboxie), dragging the .XPI into the window hangs the computer (or it does mine). Firefox can always be started outside of the sandbox if desired.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
