Note: If the Flash plugin is installed, make sure it is enabled in the Firefox (3.0 and above) or Sea Monkey 2 Add-ons Manager (see above); otherwise, the Flash test will not work and the "Shockwave Flash" plugin entry will not be displayed in the about:plugins list.
To see if the Flash plugin is working and what version is being used, visit one of these pages: If Flash is not installed, this may trigger the Plug-in Finder Service, which you can use to download and install the Flash plugin on Windows (see below).
From now on, when Firefox has a new feature, or a security update, you don’t have to do a thing.
It will update like clockwork without any effort from you as we roll out changes to all of our users.
Moreover if you need to reinstall it, you would need to download the latest setup from internet and then install it.
This post is specially for users who are low on bandwidth (in countries like India).
If you are a dial up user, do tell me how you manage things which has high bandwidth requirement.
