Microsoft stole my Chrome tabs, and it wants yours, too

This is a most excellent place for technology news and articles.
Very possible and even probable that they're using some chrome specific behaviour. Just like back in late 90s early noughts when so many websites were IE specific making is impossible to use without a windows installation. The effect is though that unfortunately Firefox isn't usable everywhere. Sometimes you need chrome for some specific websites. This is especially true for some self hosted "enterprise" web apps, I need chrome for one of those too.
