Issues with Firefox 4 after Natty upgrade

[dargaud]

Hello all,
a couple of issues with FF4 since the upgrade:
- No more adblock. I guess I'll just have to wait for an addon upgrade unless someone has a suggestion. I was surprised to discover how much ads there are on the web after all this time !
- No more TabMinWidth. OK, solved by editing the userChrome.css file
- The forward button often doesn't work after hitting 'back' (it stays grayed-out)
- Now for the weird issue: when I close a tab, it leaves a blank space in the tab bar !!! (see screenshot)

I'm not running Kubuntu , but Adblock is up and running with FF 6 Nightly Alpha 1. I have the Compatibility Reporter and the add-on is marked as compatible by the developer . I don't like to recommend this , but try reinstalling .

I have the Firefox 4.0.1 that comes with Ubuntu and in the plugins it says: Adblock Plus 1.2.2 disabled - incompatible with firefox 4.0.1. I don't even have the option to remove it in the browser, but after I ran "aptitude remove xul-ext-adblock-plus" then I could install the in-browser version. THanks.
