That was more apt to Microsoft with Internet Explorer.
Back in the olden days over 20 years ago. Netscape was the prominent web browser. Back at the time The Applications installed on Windows were just baby versions of the real Application, just enough to get you to the next step. So IE was installed in Windows 95 mostly for the purpose of downloading Netscape. While IE was fast and light, it lacked way too many features and didn't support too many of the "Modern" HTML Language. features. Making most page render poorly.
However Netscape was the big name in high tech, and was getting very popular, and started talking things that were scary to Microsoft. Such as the Web Browser being a cross platform application engine, and even replacing the Operating System for the Desktop as we know it towards a new form of thin client.
The objective of the Browser war was to put MS in such a dominate position that it could control the Web Standards and keep it closed to MS only, where all future web development and application development would be for Microsoft only.
Now this seemed like it was working IE won the browser war by IE 6.0 on XP. However Microsoft stayed on IE 6 for way too long, people began to want more out of their browsers. First with a bunch of major security attacks on IE (especially with Active X nonsense) made PC users willing to switch to Firefox as a safer browser. Where they shortly learned that it supported newer HTML features, then later the WebKit based browsers Chrome, Safari... came out supporting these new features as well. So developers started coding to the standards more than to IE, and just hacking IE Compatibility so it works.
By the time IE 7 was released there were too many apps that still supported the broken browser and the outside pages used the newer browser. So it was the case IE for intranet and Others for Internet.
Then we got that sneaky iPhone and then Chrome (Both with WebKit based browsers) that supported the Web Standards better than The current version of IE on a high speed desktop....
So in short, If you are going to take that challenge make sure you meet your objective.
