This could be helpful for people looking for specific information about a given browser. It will spare the userthe need to always check at the compatibility table or marker to ensure that what is reading is relevant to his needs. We would also possibly wish ; Filter at the content level : The same as the above but directly into the content.

However, the features range of platform we want to cover on MDN is quite wider and such a specific browser and allow mechanism on MDN could make things unnecessarily difficult to maintain.; Filter at the compatibility data level : In this scenario we want to let the user decide which compatibility data he wants to see . In this case, the features of content and the page remain untouched, only the version displayed data are shown or hidden. The examples of it's choice filter upon compatibility tables (this see above) is especially handy for Firefox OS or XPCOM component)a good use cases.
