I suggest that the Slimjet Browser package should be added. As for now it is only available on the AUR repo . It is one of very few Chrome-based browsers with a default and built in Mouse-Gestures that works well on Linux (without the need for the double click "workaround" to reach the browser context menu). It is also easy on computer resources.
Note: For those who wants to try Slimjet, at FIRST launch enter
$ /usr/bin/flashpeak-slimjet %U
