I can't use this addon anymore, because I had massive problems with different websites e.g. ebay. Links / buttons / searches were not working / opening anymore. After deactivating every addon and activating them one for another, Forecastfox (4.5 on FF 54) was resulting that problems.
The problems are not in the extension, - problems in Firefox: there is an error in processing "chrome.webRequest.onHeadersReceived" method for these sites But I want to please you - in new versions of Firefox, including in Firefox Nightly 57.0a1 (2017-08-02), this problem has already been fixed
