Keeping your plugins with any new Firefox version

The new Firefox cycle version is such that you might lose all your beloved plugins on each new release.

Fortunatly, most of the plugins still work even when the version updates, so you can still use them.

The easiest way to automatically enable them all is to update a boolean value in about:config that will tell Firefox to not disable older plugins.

The key changes for each version, but is called extensions.checkCompatibility.X.Y where X and Y are the version number (like X=7 and Y=0 for the 7.0 release).

Create the key (as a boolean value), and set it to false.
