Reader by Baris Derin is one of those Firefox add ons that makes reading on the browser much easier. All too often websites use fonts, colors and styles that are hard on the eyes, but this add on is going to take care of that. Once you install this app, reading won’t be an issue anymore.
Checker Pus from developer Jason Savard is a Gmail notification extension for Chrome that does exactly that, but this program can do a lot more. For one thing, it can read the notifications out loud, something other apps can’t do. It’s also very accessible since it’s just a click away on the Chrome toolbar, but there’s more.
YouTube High Definition is a Firefox add on that will play all YouTube videos in HD. Developed by Baris Derin, it’s a nice and free add on that allows you to watch YouTube without having to change the settings for each video, but YouTube HD can do quite a bit more.
