Slashdot It! Gran Paradiso Alpha 1 is an early developer milestone for the next major version of Firefox that is being built on top of the next generation of Mozilla's layout engine, Gecko 1.9. Gran Paradiso Alpha 1 is being made available for testing purposes only, and is intended for web application developers and our testing community. Current users of Mozilla Firefox should not use Gran Paradiso Alpha 1.
Gecko 1.9 Alpha 1 introduces several new features which can be tested by using Gran Paradiso Alpha 1:
- Cairo is now being used as the default graphics library, affecting all graphic and text rendering
- Cocoa Widgets are now used in OS X builds
- An updated threading model
- Changes to how DOM events are dispatched (see bug 234455)
- Changes to how elements are loaded (see bug 1156)
- Changes to how web pages are painted
- New SVG elements and filters, and improved SVG specification compliance
Some of the changes in Gecko 1.9 Alpha 1 will affect the web and platform compatibility of Gran Paradiso Alpha 1:
- Windows 95, Windows 98 and Windows ME are no longer supported platforms
- OS X 10.2 is no longer supported, and OS X 10.3.9 or higher is recommended
- Moving DOM nodes between documents now requires a call to importNode or adoptNode as per the DOM specification.
Downloading and Installing
Before installing, make sure your computer meets the system requirements.

Installing Gran Paradiso
Once you have downloaded Gran Paradiso, follow these instructions to install:
Double click the Gran Paradiso Setup Alpha 1.exe installer to start the install.
Mac OS X
Double click the Gran Paradiso Alpha 1.dmg Disk Image to uncompress and mount it. Your browser may have already done this for you. Double click the GranParadiso Disk Image to open it in Finder and drag the Gran Paradiso application onto your hard disk. Do not double click the icon in the disk image! Be sure to drag the Gran Paradiso application out of the disk image and onto your Hard Disk before running it. Drag the icon to your Dock if you want it to appear there.
Extract the tarball and run ./firefox:
tar -xzvf granparadiso-alpha1.tar.gz
Extract the compressed archive and run firefox
Uninstalling Gran Paradiso
To uninstall Gran Paradiso, follow these instructions:
From the Start menu, choose Control Panel. When the Control Panel appears, double click Add/Remove Programs. Find "Gran Paradiso (3.0a1)" in the list and click Remove to uninstall.
Mac OS X
Drag the GranParadiso application to the Trash.
Remove the firefox folder.
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.
Gran Paradiso stores your user data in one of the following locations:
|Windows 2000, XP||Documents and Settings\ |
|Windows NT||WINNT\Profiles\ |
|Mac OS X||~/Library/Application Support/Firefox|
|Linux and Unix systems||~/.mozilla/firefox|
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 1. Please read this before reporting any new bugs, and watch for updates as new bugs are discovered.
- 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.)
- Gecko now sends WHATWG DOM events when going online or offline (see bug 336359.)
- There have been many bugs fixed by changes to the behavior of nsCaret.
- 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-modeand on Mac OS X, run:
When running in Safe Mode, you can disable the add-ons that are causing trouble and then restart to try again.
cd /Applications/GranParadiso.app/Contents/MacOS/ ./firefox-bin -safe-mode
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.
