Hello. For some time, under each entered expression in the sent post office there has been a red "wavy" underlining. The problem is to choose a language. In my case it is Polish. Unfortunately, in the Firefox browser, which I use, there is no option to change the language to Polish (Annex 1) as it is in the Google Chrome browser (Annex 2). Why? I would like to add that this phenomenon only occurs in the case of Onet in Firefox. How can this be removed? Regards Alex.
