Most of developer love Firefox for their plugin who support for making development easier and faster. many of us use Firefox nightly build aka minefield who update daily. there is a little problem in minefield that there is less plugin on addons site of mozilla for Firefox nightly [minefield].

a solution for this problem is that you need to install the plugin who you want in nightly build from the developer site instead of add-ons site of Mozilla.

the reason for that is all many of popular plugin in development for support Firefox 4.

How to install

follow the thing as mine :

go to minefield > addons or toolbar  > addons

you see a list of plugin who is not suitable for minefield now go to more link of plugin who you want to get work in Firefox 4.

When you click their you go to plugin page on addons site of mozilla or maybe redirect you to developer site.

if they show you plugin page then go to developer site by click on link more about developer.

now you find that on the developer site they give you the same version or maybe new then you found on mozilla addons site.

install the plugin and restart the minefield. you see that most of plugin now work.
