Eclipse and Firefox 3.1 on Linux
Eclipse and Firefox 3.1 ( or XulRunner 1.9.1 to be more precise ) don’t work well together on Linux. Using MOZILLA_FIVE_HOME and LD_LIBRARY_PATH yields no results.
Fortunately, there is a workaround: have FireFox 3.0 ( or XulRunner 1.9.0 ) installed as well, and modify your eclipse.ini to contain
-vmargs
-Dorg.eclipse.swt.browser.XULRunnerPath=PATH_TO_XULRUNNER_1.9.0
