OK, I finally gave up. I am happy with Opera and IE at the moment, but there was so so much buzz about Firefox, I decided that I will install and use Firefox for a while and see it for myself. Installation went OK, but the Installation options need a bit of rework. Started using the program, found it fast and rest of the things that are already repeated 1000 times around different blogs.
Although I have nothing against Firefox, but still it lacks too many features that Opera has and on the other hand, if I switch to Firefox I loose too many benefits that I get while using IE, i.e. access to all the toolbars and stuff.
There are many many tools that I use within IE, for example Newsgator plugin, Google Toolbar, and recently OneNote Powertoys. Now all these tools help me to increase my productivity, so can anybody tell me why should I make the move to Firefox ? Do I hear anybody wisper that we will have those toolbars in Firefox soon!
Update:- Thinking about this, with more than 1 million downloads, would love to see how many people stick to Firefox until the end of the month, i.e. use it religiously and dump IE.
