Dennis sent in a submission about a toolbar he's created to work with the Zend Debugger (in an extension) for the Chrome Browser:

Since i have not yet seen an official extension for chrome (or i have not looked hard enough), i created one so i don't have to switch back to Firefox all the time, while I wait for the official extension. It only has the basic functionality (debug, debug next, profile and some configuration options) and it probably has some bugs and quirks, but it functions fine for me.

You can download this toolbar from here and if you have issues installing it, you might check out this post on the Zend Forums.
