Today I find that Vimperator (3.8) is not compatible with Firefox 18.0. This makes me really upset. I've tried other add-ons like VimFx but I think Vimperator is the best.

Do you have any solutions other than changing the Firefox 18 back to Firefox 17?

The minimum compatible Firefox version to work with Vimperator 3.8 is Firefox v20, as you can see from its own install.rdf manifest. So you will have to either update Firefox or if this isn't possible for some reason, find an older version of Vimperator.
