The microsoft internet explorer is a very old browser launched by microsoft for their window operating system
The browser is outdated and thus have many loopholes and security issue
First of all the loading time of webpage is lot more slower compared other browser
The browser don't have any special features like icognito mode and lacks many features that other popular browser has
The browser also crashes many times and need to be updated
Also the flag content won't run on this browser and so many contents won't load on this browser
There is a newer version camed of this app which is named as edge browser
Overall I recomend to upgrade to edge browser or some other good browser to avoid any security issue
Thank you
