This article explains how to install Flash. Install Flash Plugin Manually in Firefox I use Firefox Portable at work but unfortunately don't have the necessary admin rights to update flash. Unfortunately new versions of Firefox don't seem to include the most up to date version by default. Installing Firefox add-ons manually. Now that you have downloaded the extension, you can install it directly in compatible versions of Firefox. It is alternatively possible to extract the xpi file to the system first.

How to Manually Uninstall a Globally Installed Firefox Extension Chris Hoffman @chrisbhoffman March 12, 2013, 6:40am EDT Firefox provides several ways for other programs on your computer to install Firefox extensions, sometimes without your explicit consent.

For many, one of the biggest obstacles in Linux is installing applications. Because the computing world has grown so accustomed to click and install, the idea of having to manually install something is very foreign. And that is one of the reasons Firefox and Linux sometimes make for a deadly combination. But it doesn't have to be that way.
Installing plugins for the Linux version of Firefox isn't that difficult..once you know what you are doing.
We'll start with the most difficult plugin first. Nch video recording software.
This blog post is also available in PDF form as a TechRepublic download.
Java
Java is a plugin that, unfortunately, requires an entire runtime language to be installed on your machine. To do this you need to install either Sun's or IBM's Java Runtime Engine (JRE)
(NOTE: There is also a Blackdown version of JRE, but at the time of this writing, its site was down so no link could be provided.) Install Firefox Esr Plugin Manually
Let's go with the SUN version (because you don't have to register on its site to get it). You will be able to download either a self-extracting file or an rpm in self-extracting format. Which form you choose to download will depend upon what distribution of Linux you use. I am running Fedora, so I will download the rpm format.
Once you download the file, you will first have to open up a terminal window (yes you are going to have to run a few simple commands) and su to root. Once you are the root user, you will issue the following commands from within the directory where you saved the self-extracting file:
where XXX is the release number and architecture.
You should not get any errors. Once you have done the above, it's time to help Firefox to work with the new runtime environment you just installed. You're going to have to create a symbolic link to a specific file within the JRE environment. The symbolic link will be created inside your browser's plugin directory.
You can do this two ways: globally or per-user. If you are the only user on the machine, it's best to do it in your ~/ directory. Let's do it that way. As your normal user, issue the command cd in the terminal window. That command will change you to your home directory. Next, issue the command cd .mozilla/plugins. Now you are in the correct directory to make your symbolic link. You need to first find the file libjavaplugin_oji.so on your machine. To find that, run the command:
When I run the command I get the results:
/usr/java/jre1.6.0_02/plugin/i386/ns7/libjavaplugin_oji.so
Your results may vary. So now that I know where the file is, I issue the command that will make a soft link to the correct file.
Now, open up Firefox and in the URL location bar, enter about:plugins. You should see a listing similar to that shown in Figure A.Figure A
No matter how many applet versions you have listed, Java is now properly installed.
And that's that for Java — now on to easier plugins.
Flash
The Flash plugin is simple. All you need to do is download the correct file for your machine, install the file, and then copy libflashplayer.so to your ~/.mozilla/plugins directory. Let's stick with the rpm-type file.
Download the flash-plugin-XXX.i386.rpm file (Where XXX is the release number) and then issue (as root) the command rpm -ivh flash-plugin-XXX.rpm (again, where XXX is the release number) to install flash-plugin.
As before, you are going to have to locate the correct file in order to copy it to the plugins directory. Issue the command locate libflashplayer.so. You should see this in your results:
Change to the ~/.mozilla/plugins directory and run (as root):
Now, you need to change ownership of the file so it can be used by a non-root user. Do this with the command (run as root from within the /home/USERNAME/.mozilla/plugins directory — where USERNAME is the actual name of the standard user):
Restart Firefox and run the command about:plugins and you should see a listing as shown in Figure B.Figure B
Both Futuresplash and Shockwave will be installed with this single plugin installation.
That's it.
Mplayer
The mplayerplug-in uses the mplayer application to play movies opened by your browser. Before you install the plugin, you have to have mplayer successfully installed. There are two simple ways to install mplayer (both run as root from the terminal window):
![Install Firefox Plugin Manually Install Firefox Plugin Manually](/uploads/1/2/5/3/125300273/808302853.png)
or
Once you have mplayer installed you can then install the mplayerplug-in. To do this, download the file that corresponds to your system from the mplayerplug-in site. We'll continue with our Fedora example. Once you have that file, install it with the command (run as root):
Now you have to locate the file mplayerplug-in.so. Locate this file with the command locate mplayerplug-in.so. You should see a listing similar to /usr/lib/mozilla/plugins/mplayerplug-in.so.
Copy that file and change ownership of it. You have to copy the file in the same way you did the libflashplayer.so file above. So as root, issue the command:
And then run the command to change ownership to the standard user:
Restart Firefox and check about:plugins to see a listing for mplayerplug-in. This time, however, you will not see a listing for mplayerplug-in. You will see that video (in various formats) is supported (as shown in Figure C).Figure C
A listing for video support will indicate that the mplayerplug-in is properly installed.
That's it.

Final thoughts
You now have the most useful plugins installed for Firefox. Naturally, there are tons more plugins available. Fortunately, they are all installed in a similar manner. So hopefully, you now see that installing plugins for Linux Firefox isn't nearly as difficult as you thought.
Happy browsing (in Linux!)

It is usually not necessary to download Firefox add-ons manually from the Mozilla website. There are however situations where this may be your only course of action.
Maybe you want to install an add-on on a device without direct Internet connection, a development machine for example.
Security conscious users may want to download extensions too as it provides them with options to go through the source code before they install the add-on in the web browser.
And then there are situations where add-ons are not compatible with the version of the browser that you are using. It is often possible to modify the source of the extension to make it compatible.

When you visit the official Mozilla Add-ons repository you won't find direct download links listed on it.
That does not mean that there is none, only that it is not displayed directly on the page.
Download Firefox add-ons manually
Here is what you need to do to download Firefox add-ons manually.
- This works on pages that list multiple extensions and on individual pages of add-ons on the Mozilla website. It is also interesting to note that this works for other programs such as SeaMonkey as well.
- Locate the Add to Firefox button on the page you are on. You may need to move the mouse cursor over the add-on to display it on list pages while it is displayed by default on profile pages.
- Instead of left-clicking on it to add it to the browser, right-click on it and select Save Link As.
- This opens a prompt that you can use to download the add-on xpi file to your local system.

The download dialog for the add-on
Note: This works in all modern web browsers. When you use a different browser, a download button may be displayed directly instead which you can click on to initiate the download.
Mozilla displays a prompt then underneath the download button. Here you need to click on download anyway to download the extension to the system.
Installing Firefox add-ons manually
Now that you have downloaded the extension, you can install it directly in compatible versions of Firefox. It is alternatively possible to extract the xpi file to the system first. You can use a program such as 7-Zip for that.
Once done, you can edit the source code as you see fit or audit it.
To install the extension in Firefox, simply drag and drop the downloaded file on a Firefox window. The installation dialog opens up and you can install the add-on as usual.
If you do not like drag and drop, you can open about:addons alternatively, click on the 'Tools for all addons' button at the top next to the search form, and select the 'Install add-on from file' option that is displayed here.
