I'm generally not one to follow the crowds. I prefer to have a good reason for doing something, which is why I hadn't yet moved across to Firefox. I didn't really see any major issue with using IE, and I don't think it's a bad browser. I still like the browser, and haven't really had any clear problems with it... but I just heard of another security flaw in Internet Explorer 6.
So I've just installed Firefox, and will only use IE for the rare case where Firefox isn't so grand (i.e. blogging). Until Microsoft can release a completely new version of Internet Explorer that doesn't have as many security holes, I'm just not happy using it. Sorry MS... you've just lost another one to Firefox. I gave IE its fair chance, and it has been proven weak.
Taking into consideration the amount of confidential and highly sensitive personal data that travels around between browsers and servers, I think it would be a good idea to be as secure as possible. With all the technology that allows you to securely do Internet banking, etc. you're still only as secure as the weakest link in the chain. Unfortunately, Internet Explorer seems to be that link. Now I just have to show everyone else I know that it exists! After all... the biggest group of people that know about Firefox seem to work in the IT industry. This needs to be “marketed” outside of that arena if it's really going to be a force to be reckoned with!
So I'll be using Firefox from now on. MS... it's time you sorted out IE. Longhorn will be good I'm sure, but maybe you should take a few developers off that and let them sort out IE for a few weeks. Just a suggestion.
