I get a JS error in Firefox only and no translation when I click on translation buttons,
The JS error I get is
in element_main.js on line 402, it fires only when clicking on a translation button, only in Firefox,TypeError: this.k is undefined
For the Google Default method I get no flags in the list and no error at all,
I didn't activate the Analytics feature.
I tried a lot of things in the last days but no luck so far,
Where should I look further? Does the PRO version solve this?
