Today, Firefox has offered to install an update for Fast Dial marked 2.6. I, not thinking too long, did it. And in vain - Fast Dial flew. I thought that I was probably in conflict with something, I tried different combinations, but nothing helped.
In general, the solution was quite simple -
install the next version - 2.8 (thanks to
userlogos.org ).
UPD: using third-line firefox (3.0.2).
