I want to use FireFox 12 for GWT development.
But this version is NOT officially supported by Google.
I found
http://notepad2.blogspot.de/2012/04/gwt-developers-plugin-for-firefox-12.html
Is it save to use this plugins? Or I am in danger to catch malware?
Stefan, I use mainly Firefox in my GWT projects and was able to switch to FF12 thanks to Alan Leung of Google who posted Dev Mode plugin builds for FF12 on all major platforms. It’s safest to download the plugin from there. I’ve been using the Mac universal binary build for about a week now without a problem.
