available for download to Web application developers, our testing community and users who want to get a sneak peek at the next version of Firefox. Please note that at this time, users should not expect all of their extensions, plugins and themes from previous versions of Firefox to work properly.
What's New in this Development Milestone There is a lot in Firefox 2 RC 3 that you can play around with and give us feedback on: * Visual Refresh: Firefox 2's theme and user interface have been updated to improve usability without altering the familiarity of the browsing experience. For instance, toolbar buttons now glow when you hover over them. We will continue to improve the look and feel throughout the release candidate process.
Phishing Protection warns users when they encounter suspected Web forgeries, and offers to return the user to their home page. Phishing Protection is turned on by default, and works by checking sites against either a local or online list of known phishing sites. This list is automatically downloaded and regularly updated when the Phishing Protection feature is enabled. A new search engine manager makes it easier to add, remove and re-order search engines, and users will be alerted when Firefox encounters a website that offers new search engines that the user may wish to install. Power users who open more tabs than can fit in a single window will see arrows on the left and right side of the tab strip that let them scroll back and forth between their tabs. The History menu will keep a list of recently closed tabs, and a shortcut lets users quickly re-open an accidentally closed tab. It will be activated automatically when installing an application update or extension, and users will be asked if they want to resume their previous session after a system crash.
microsummary (a regularly updated summary of the most important information on a Web page), users can create a bookmark with a "Live Title". Compact enough to fit in the space available to a bookmark label, they provide more useful information about pages than static page titles, and are regularly updated with the latest information.

Troubleshooting * Poorly designed or incompatible Extensions can cause problems with your browser, including make it crash, slow down page display, etc. If you encounter strange problems relating to parts of the browser no longer working, the browser not starting, windows with strange or distorted appearance, degraded performance, etc, you may be suffering from Extension or Theme trouble. Disable the Extension/Theme that is causing trouble and then start normally. If you uninstall an extension that is installed with your user profile (ie you installed it from a Web page) and then wish to install it for all user profiles using the -install-global-extension command line flag, you must restart the browser once to cleanse the profile extensions datasource of traces of that extension before installing with the switch. If you do not do this you may end up with a jammed entry in the Extensions list and will be unable to install the extension globally. If you encounter strange problems relating to bookmarks, downloads, window placement, toolbars, history, or other settings, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Migrate your settings files (Bookmarks, Saved Passwords, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file. We need help from developers and the testing community to provide as much feedback as possible to make Firefox even better.
