When trying to add a component in the base area, the placeholder link triggers Firefox' own popup blocker unless you've allowed popups from localhost generally. The page editor bars - including the add button from the base area - and their popups work as expected with no problem. The problem is the placeholder link.

While it is easy to simply add that exception for popups from localhost (or whatever site this version of magnolia is running on), it might not be so easy to achieve that in some clients' environment where a single user cannot allow these due to company policies. If there is a workaround for making this work in FF without having to add an exception to the rules, it would be most preferable.

Tested this also in Safari 5.1.2 and Chrome 16.0.912.77 on Mac OS X and it worked normally. Seems like Firefox is the only troublemaker this time (maybe check IE 9 as well)
