Here you can download firefox 4 rc1, and xulrunner 2.0.0 rc1http://www.wuala.com/krab/Public/pardus/firefox/
I had to work hard to build it. Basically we used the build files from the official repository (ff4b9). But I had to disable a couple of patches, due to non-compatibility. (firefox-multilocale-chrome.patch was fixed for work) and remove all side of bookmarks and search engines.
The reason was the lack of updates, even in the devel repository.Note!
If you install these packages, they will be replaced by ff4b9 at the first update. Since they are not installed from the repositories. Here is a gift from the manager pisi. As a solution, do not update the worse version of these packages.Note!
You can build the 64 bit version.
To do this, download the same link two archives in the folder build-files. Unpack them into one directory. First build xulrunner and install it manually, then firefox.
