MY PREVIOUS WAS BROWSER INTERNET EXPLORER The trouble all started when Microsoft integrated IE into Windows as a required component, and made it difficult to uninstall and use an alternate browser. Microsoft Stopped Trying:- By the time Microsoft released Internet Explorer 6 in 2001, complete with lots of new features for web developers, since there was no competition and they had a 95 percent market share.

Microsoft-Specific Features:-The whole problem with Microsoft’s innovation is that much of it was done in ways that didn’t follow the web standards—this wasn’t as big of a problem when Internet Explorer was the only game in town, but once Firefox and Webkit came around and started following the standards correctly, suddenly it became a huge problem for web developers. Security Holes and Crashing:- Since Microsoft decided they didn’t need to try anymore, and they didn’t keep up with the competition from Firefox and other browsers, bugs and security holes just cropped up left and right—really terrible ones, too. For instance, this code is all that is required to crash IE6:

IE7 and IE8 Were Too Little, Too Late:-It took five years after IE6 for Microsoft to finally get around to releasing IE7, which added tabs and made the browser slightly more tolerable. . The Real Reason Geeks Hate IE

Just because we’re geeks doesn’t mean we hate everything that’s inferior and outdated—in fact, we often love retro computing—that’s why we love Atari, NES, Commodore 64, etc. We take pride in our geek knowledge. So why’s Internet Explorer a different story? Here are a couple of reasons that fueled our hatred of the buggy browser, and finally put us all over the edge: Supporting IE is Like a Fork in the Eye for Web Devs Luckily by 2014, Internet Explorer 6 and 7 are a statistical anomaly in actual Internet usage, and most of the bigger websites have completely stopped supporting them. Even Internet Explorer 8 usage has dropped to single-digit percentages for many websites. Geeks Being Forced to Use Internet Explorer 8

And here’s where we come to the real issue—the whole reason that geeks can’t stand Internet Explorer: Geeks everywhere were forced to use Internet Explorer at work even when there are better browsers, forced to support it for corporate applications, forced to make sure web sites still work in IE, and we couldn’t convince everybody to switch to a better browser.
