Which popular browsers have gone into obscurity?

As the internet moved through the years of modernization, certain apps which were kings of the game, became obscure. This is because they failed to adapt the app to the modern user need. One such browser is internet explorer. As the modern tech took over, the browser failed to increase its pace to match that of the others around it. As a result, the internet explorer became slow and outdated.

It failed to support some of the common formats that were becoming the norm on the internet. Moreover, it was impossible to code on the browser due to immense lag issues. As a result, people shifted from liking the browser to slowly detesting it and moving on to a new one.
