Webcompat.com Reporter for Android Mobile di Mike Taylor, Thomas Wisniewski

The webcompat.com reporter extension adds a menu item which allows users to report issues with any site on the web.

Sometimes, sites have bugs or policies that prevent them from working well in every browser. The community at webcompat.com works to help web developers and site owners identify and fix such issues.

If something appears broken, but works in another browser, or if a site or app insists you install another browser this is likely a web compatibility issue that you can report with this add-on.
