In my opinion, best in this category is firefox!!!! 
I use other applications like evolution,thunderbird and gimp!!!!
Which one do you use???

Firefox, WordPress, Inkscape, GIMP etc. There are lots of them these days. Nice to see reliable open source software are there to proprietary ones. Not everyone can buy software. Especially if you are a student or domestic users. And you would still want to have to those awesome features on your computer. These great gifts prevent people from going to malware infested illegal copies of paid software.

Anyone tried Electron ? It will help you build cross platform apps. Like it is a super easy way to build a software for Windows, Linux or Mac.
