Firefox on the Mac doesn't use the word GoogleToolbar in the user agent string, so the rewrite rule won't work. Here's the full string:

Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; nl; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 GTB6

So the rewrite condition should perhaps look like this:

RewriteCond %{HTTP_USER_AGENT} (GoogleToolbar¦GTB[0-9]+) [NC]

The ¦ should be a solid pipe...

But I agree that is a bit harsh to block users just because they might abuse SideWiki.
