One of the features that all modern OS’s require these days is that they update themselves on a regular basis. Ubuntu is no different and normally the process is as smooth as smooth can be. Occasionally though it introduces a problem – such as the one I now experience on an irregular basis when Firefox simply dies. One second it’s all fine and the page is downloading normally, the next there is no more Firefox. It’s only been happening since a recent update and started within minutes of that update being applied.
Hopefully there will be another update soon that will fix it.
