Answer by Rob W http://stackoverflow.com/questions/9847580/how-to-detect-safari-chrome-ie-firefox-and-opera-browser/9851769#9851769

Googling for browser reliable detection often results in checking the User agent string. This method is not reliable, because it's trivial to spoof this value.
I've written a method to detect browsers by [duck-typing][1].

Only use the browser detection method if it's truly necessary, such as showing browser-specific instructions to install an extension. Use feature detection when possible.

Demo: https://jsfiddle.net/311aLtkz/

JS library based on the File API to cache images for offline recovery (target: cordova/phonegap & chrome) https://github.com/chrisben/imgcache.js

This library is using HTML5 file api system. Some of File Api method is not supported in safar and Mozilla firfox. Here in above two example we are using canvs and File reader to storae image data in local storage for offline access.
