Works great, until the Mozilla version rapid increase.

This is how I fixed it ...

Downloaded the file bulgarian_dictionary-4.3-fx+tb+sm.xpi and opened it with an archiver.
Then chose and edited the file install.rdf
There is something like X.Y at few places and since I don't know the id of the TB or FF I changed the value X.Y to 9.0 at all places.
Then just installed manually the file from TB.
Works fine.

Прекрасна работа ми вършеше, докато не инсталирах 5.0 версията на програмата :(
Дано по-скоро я направят да работи на нея :)

Много добра добавка

In most of the cases it works fine. However there are some specific verbal forms in Bulgarian that are not correct. For instance the verb "да падна" cannot have passive forms as "паднато, падната", etc.

Not working with 3.0b2 of TB.

Не работи с версия 3.0b2 на TB.
