needs as many caching options as 'cache viewer' Rated 3 out of 5 stars

Cache Viewer https://addons.mozilla.org/en-US/firefox/addon/2323 had many many more caching options

CacheIt needs a bit of an upgrade ;)

This review is for a previous version of the add-on (1.0). 

Sorry I took so long to update. If you still use CacheIt!, the new version 2.0.3 has addition cache providers to choose from, as well as a few other useful features. The new version has not been reveiwed yet; however, you may download load it from the versions page.
