Hooray! Rated 5 out of 5 stars

Yay! Extended for FF3!

This should be included in a build for developers. This is such a vital tool for making Firefox extensions and even handy for other web developers (live HTML preview, JavaScript environment, and regular expressions--the immediate feedback without needing to open a new window, save a test file to a folder, etc., is invaluable in speeding development). The extension builder got me into building extensions in the first place.

Be aware of the toolbar icons (View->Toolbars->Customize) as they are a must.

Small note: with the XUL editor, if you open it in a new window, it seems to have fewer privs (had problems testing a controller).

One request: please allow customization of default text in windows, at least the HTML editor. If not, please at least make the default HTML text include a fully well-formed document and an empty script tag to try out JavaScript so we can play with JavaScript/HTML/CSS interaction without needing to type the script tags in each time...

An XHTML 1.1 editor might be nice too to get immediate well-formedness errors, though one can kind of use the XUL editor for that (though not with real HTML styling).

Small bug (with FF3?): Might not be ext's fault, but reloading chrome (with a lot of windows open at least) caused FF to crash, and I had problems in FF2 with reload chrome causing multiple windows to be opened when reopening Firefox later.

Again, awesome work, thank you!
