i'm on Chrome, it's working for me. Do you have any extensions blocking sounds/ads, etc etc? are notifications within your firefox browser settings turned off?
install direct plugin from admin panel. that is, look for the winrar and import it. now. There is an xml extension file called language- russkjj that now copies it to the server directory where I have the forum. I hope it works for me now
ahhh yes ok. do you have "archive import" enabled in your add-on section? If you don't, you can go to your hosting server, then /src/config.php and add the line: $config['enableAddOnArchiveInstaller'] = true;
that way you can install the addon by archive, that is if you aren't already doing it that way
Sorry my english is not very good. I mean the extension format of the audio file. for example the format of the audios in the sound notification / sound folder is MPEG (.mp3). do you have it like that too?
