i have to add a dictionary add on in firefox it says permisssion requierd for all data hwto i allow thta in that extension

Hi

When you add the dictionary there will be a prompt where you can grant permission.

i did but it didnt work like it has a dot onthe equired permission butit cant be selected for reason

Could you please provide a screenshot of the "dot on the required permission" and/or the name of the extension? I just installed 3 random extensions for dictionaries and I'm not sure what you are referring to.

i have adde an extenstion for dictionary in firefox and it requiers some permission for data how do give that permission

You are using one of the dictionaries listed on https://addons.mozilla.org/firefox/language-tools/ ?
