Firefox 3.0 Alpha 5
Firefox 3 is focused on improved memory handling, performance, and stability, improved XUL, and new core components such as application data stored in SQLite. Firefox 3 could break a few existing extensions and applications built on top of Firefox, and it will definitely include new optimizations if you like to build on the popular browser. Firefox 3 should have additional JavaScript and SVG features if you’re into that sort of thing.

Uninstalling Gran Paradiso

These instructions leave your profile in place in case you install Firefox again in the future. If you wish to remove your profile folder, remove the location described below in the “Profile Folder” section. Note that by doing this you are destroying all of your downloaded Extensions and Themes, Bookmarks, saved passwords, settings and other information and should you decide to use Firefox again you will be starting with a clean profile.

Add-ons
Add-ons installed under previous versions of Firefox may be incompatible and/or require updates to work with Gran Paradiso. Please report any issues to the maintainer of the extension. When you install Gran Paradiso, all of your Add-ons will be disabled until Gran Paradiso determines that either a) they are compatible with the Gran Paradiso release or b) there are newer versions available that are compatible.
This list covers some of the known problems with Gran Paradiso Alpha 4. Please read this before reporting any new bugs, and watch for updates as new bugs are discovered.
All Systems
- The Cairo graphics system has drastically changed the way all text and images are rendered from previous versions of Gecko, so occasional misrenderings of non-latin scripts and fonts may occur.
- The Phishing Protection notification bubble is hidden by the content area (see bug 341950.)
Windows
- Upscaling images can result in misrendering, causing the edges of the image to appear blurry.
Mac OS X
- The user’s choice of a default font may not always be honored.
- Font decorations such as underline and strikethrough may be drawn incorrectly.
- Complex script (ex: Indic) may be misrendered.
Linux and Unix systems
- Loading any page with Chinese, Japanese or Korean text can hang the browser (see bug 357637).
- Performance on complex script (ex: Indic) may be slower than previous versions of Gecko.
- Compatibility issues have been reported when users are not running Xorg 7.0 or better.
- Users may experience problems when attempting to print complex pages.
- Poorly designed or incompatible Add-ons 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 trouble with your Add-ons. Restart the browser in Safe Mode. On Windows, start using the “Safe Mode” shortcut created in your Start menu or by running
firefox.exe -safe-mode. On Linux, start with ./firefox -safe-mode and on Mac OS X, run:
cd /Applications/GranParadiso.app/Contents/MacOS/
./firefox-bin -safe-mode
When running in Safe Mode, you can disable the add-ons that are causing trouble and then restart to try again.
If you uninstall an extension that is installed with your user profile (i.e. 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. Create a new profile by running Firefox with the -P command line argument, choose the “Manage Profiles” button and then choose “Create Profile…”. 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.

Gran Paradiso works with whatever mail client is the default on your system. However, we recommend Mozilla Thunderbird, our next generation email client and the perfect complement to Firefox.
