I have just upgraded to version 18.104.22.168 from 22.214.171.124. Upon starting firefox I get warnings that the british dictionary addon is incompatible with this version of firefox.
I had a look at the install.rdf for the dictionary, and the maxVersion it mentions in there is 2.0b2.
Any help/suggestions appreciated.
I lay awake last night wondering where the sun had gone, then it dawned on me.
