Firefox is free software in every sense of the word, not just according to Stallman.
I have two criticisms of FF:
1. I tried Avant and found it buggy. It would crash often. But one thing I liked a lot was the tabbed browsing in Avant. I know FF has it and I'm using it, but I liked the way Avant did it better. If you closed the browser, then opened it up again, the same tabs would open back the way they were. If you hit "Home", you went ton one page. In FF, you have to program "Home" to be a series of tabs in order to open up multiple tabs. If I click "Home" now, I open up a bunch of new tabs in addition to the ones already open, even if I just wanted to go back to one page I would have designated in Avant or IE. FF needs to change this.
2. Controls. I realize on point FF is trying to make is that Active X is a haven for problems, however, there are sites that use this (or something else that FF doesn't like) and there is no way to utilze that site. On one site I use, quite extensively, I have to open up IE to use it because nothing happens when I click on "buttons" on that site.
In my view, these are two very serious problems for FF.
WEll.... focus.self; self.window=null; self.close() doesn't work in firefox. =/
I have Firefox on my computer. I've used it from time to time. I've tried most the extentions.
It's still clunky compared to Opera.
I just don't understand the love affair with Firefox that, appearently, many people have. When compared side by side with Opera it loses, big time. This is admittedly MY opinion, but I find Opera faster, more customizable, better looking (with the right skins), more intutitive, more feature rich and just plain better.
When using Firefox I feel like I'm in 1994 again using Netscape. It seems like a step backward.
Firefox is a huge PITA when trying to load certain webpages. Putting the National Weather Service radar into motion literally takes almost a minute, while in IE it was nearly instaneous.
I like Firefox it's a good browser and you don't need spywaare removers like you do with MS.
There is one site I have found that will not load on it due to incompatibility. I will only use IE now for the rare page the needs IE to open.
I am stll exploring and finding goodies in Foxfire that I like better than IE.
