What is Side View?
Side View is a Firefox's Multi-tasking extension that lets you view two tabs within the same window. Instead of opening a new tab, you can simply open links in Side View without leaving current window.
Why is it helpful?

It saves us from switching tabs and going crazy. Another good thing is, You can adjust the size of Side View Window, move it to left or right or close it if you no longer want it.
