michaelleung: Being a massive FF fanboy (after something like 7 years of IE ignorance) I felt like they basically forced me to use it the way the devs wanted to, that is, with all the good stuff disabled. Also, whose idea was it to get rid of the status bar? Because that person should be shot.
Font smoothing is evil.
Rondel: Well, there is "status bar". Just hover your cursor over something and in the left bottom corner some info will appear. Same thing when it comes to loading pages.
I really love it, because I used the Fission extension for this, which now I don't need no more. You still can get the look and feel by activating the old bars. In my case I prefer to use a compact menu bar (combined with the adress bar) and the tabs under the adress bar. No problems to change this, so thumbs up for this release.
After a cleanup of unused extensions I only miss the Free Download Manager plugin, I hope they will update it soon. I guess there are some ways to activate the old extensions like in FF3 (about:config to disable check, edit extension info, special extensions), but I prefer to wait for an update this time.
Edit: I totally forgot about FlashGot. I will use it till there will be an update for FDM. So, everything is fine from my side :-)
