Firefox 7 beta 1 on Ubuntu 11.04 64 bits.
FastDial works well with FF 5 but now I've upgraded to FF 7b1 and now when I start Firefox or I open a new tab, FastDial only shows the background.
I've tested the fastdial 3.5b1_1 from here: http://userlogos.org/node/14288?page=9#comment-17265 and same problem.
