i have two version of Firefox and have two different problem that when i close one and open another then i found that they spent some second on checking compatibility of plugins so if i can stop them to check compatibility then how i can.

second thing is that are i can install plugin for separate version. like a version of Firefox have support this version of plugin and it's probably not sure that same version of plugin support in another version of Firefox.

You need to use separate profile folders for each version. Firefox will perform a compatibility check and recreate all cache files if you switch versions.

Create a new profile exclusively for each Firefox version and create a desktop shortcut with -P "profile" appended to the target to launch each Firefox version with its own profile.

See these mozillaZine KB articles for information:


Do you mean plugins (Tools > Add-ons > Plugins) or extensions (Tools > Add-ons > Extensions) ?

Extensions can easily be installed if you use separate profiles. Firefox 4 will also recognize plugins that you install in the plugins folder in theFirefox Profile Folder, but you need to create that folder yourself and copy the plugins files to it.
