As a Firefox user, I always take full advantage of the browser's extensibility by installing lots of plug-ins. As useful as they are, it can sometimes get a bit overwhelming having so many extensions, and I often find that I have plug-ins installed that perform the same function as each other and those that I never use.
MR Tech Local Install provides a very practical way of managing extensions. It gives you the option to install an extension directly or store them in XPI format in a library.
This actually makes it easier to spot when you have two extensions that perform the same task and monitor your plug-ins more closely.Local Install made managing my Firefox extensions remarkably simple, especially given the sheer number that I have installed.
Perhaps the app could've been improved further by providing suggestions of recommended plug-ins for performing certain tasks, but on the whole it's the extension to cover all extensions.
