BrowserLab for Firebug has been updated for compatibility with Firefox 4 and Firebug 1.7. It is now available for download from the Mozilla Exchange, and can be updated by using the Add-ons Manager in Firefox.
If you’re new to our BrowserLab for Firebug extension, you may be wondering why you would need it. BrowserLab for Firebug extends the usefulness of the BrowserLab service by enabling you to test pages that are not published on an internet web server. You can preview your html pages in Firefox on your local computer, then use BrowserLab for Firebug to push the local source to the BrowserLab service, where it will be rendered in multiple browsers. This means you can use all the power of Firebug to poke, change and debug your page locally, then test those changes/fixes across browsers in BrowserLab.
Another good reason to use BrowserLab for Firebug is to test sites behind HTTP authentication. E.g., let’s say you’re working on a new site for a client, and have the site hosted on a test server you use. Because the site is confidential, you’ve enabled simple HTTP authentication on the site. If you tried to view a page on this site using the BrowserLab client at http://browserlab.adobe.com, you’d find that the authentication prevents our browser servers from seeing your pages. But with BrowserLab for Firebug, you’d simply open Firefox, log into your site, then use BrowserLab for Firebug to Preview Local Source to the service, and see your page rendered in multiple browsers.
We hope you enjoy BrowserLab for Firebug!
