I am using Firefox 2.0 from the time it became official release. Some of the extensions are still not working with it, but there are other functionalities which overcome this problem.
For example, I enjoy using its spellcheck. I often write in engilsh, and when I’m in a hurry – spellcheck really helps to remove all typos. When I installed v2.0, there was not Bulgarian language. Well, today I checked again – there was Bulgarian language pack. I installed it and it works great.
Thanks to all contributors to Firefox and Firefox community!
