Why all addons installed or updated go with language different from my Firefox language?

I have Firefox 31.4.0 ESR English on Russian Win 8.1 I always use English Firefox with English-language addons. In my Options English set as a primary language. I have general.useragent.locale set as en-US.

But some time ago many addons in my installation started to use with Russian language. It's absolutely inexplicably and I can't find a solution. I want to have the same language in addons that I have in browser. Please help me.

Thank you!

Does this happen when you install the add on or after?

Some extension may check the value of the system locale.

You can open the Browser Console (Firefox/Tools > Web Developer). Paste the JavaScript code in the command line and press the Enter key to run the code.

  • Toggle the devtools.chrome.enabled pref on the about:config page to true to enable the command line
var localeService = Components.classes["@mozilla.org/intl/nslocaleservice;1"]
                              .getService(Components.interfaces.nsILocaleService);
var systemLocale = localeService.getSystemLocale().getCategory("NSILOCALE_CTYPE");
console.log(systemLocale);

Thank you, can I change these extensions behavior?
