Currently, I'm getting annoyed with Chrome, which has now refused to support Java plug-ins - along with other NPAPI plug-ins.
This means that many sites no longer work properly where Java is used, when you're using Chrome.
Of course, Google claim that NPAPI plug-ins such as Java are unstable and a security risk - however the Google stance against Java has more to do with a bitter lawsuit between Oracle (owner of Java) and Google, over allegations of copyright theft and stolen source code, than any real or perceived instability or security threat of NPAPI plug-ins.
