Any ideas? My new version now includes translations to Fr, Es, Ru, Sk, probably it has something to do with that but I cant figure out what.  
I’ve reported the bug here:

But it’s kind of urgent, I really need to release a new version asap.

EDIT:  
I’m trying now release it for Chrome as well and I get “default\_locale field is missing in manifest.” error. So this is probably similar, but my manifest file contains it and the `_locales` folder is also there and I can load the extension so I don’t really understand what could be the issue ☹

**EDIT 2:**  
**Never mind, seems like my `npm` zip tool cannot create correct zip file anymore (extracting zip and repackaging it using windows build in zip fixed the issue).**
