I will just be brief on the disastrous Microsoft Internet Explorer. The following are the reason why you should not use Internet Explorer: -
The speed: If speed is the thing you want then don’t ever use internet explorer or you may commit suicide. Jokes apart while in other browsers it takes no time to load browsers internet explorer takes forever to load simplest of webpages.
That Old Interface: The interface of Internet explorer has not changed a bit over the years, something needs to be done by the Microsoft corporation.
There are more reasons but I will recommend everyone not to use the Internet Explorer.
