Many a time we would like to test drive upcoming alpha or beta versions of firefox, and obviously most of us cannot imagine running firefox without our favourite extensions.

As usual the problem of extension compatibility crops up now, so the only option is to check all our add ons on mozilla to see if they are compatible with the version we want to install. Now this is fine as long as all we want to check is are 4-5 addons, but not if your list off addons is long.

Is it compatible? Is an yet another of firefox’s experimental add ons which will display which versions a particular addon supports.

All you need to do is install the addon from here :

https://addons.mozilla.org/en-US/firefox/addon/66590 and then open up the add on manager. Now each extension shows which versions of Firefox are compatible with it.
