  • (2020-02-10, v:0.0.33) Eliazer Braun: getting Error in console
    I am getting this error Unchecked runtime.lastError: The message port closed before a response was received. See screenshot http://adr.ma/zxJdhA
  • (2017-12-11, v:0.0.33) Joe Spandrusyszyn: Breaks Google Hangouts
    When this extension is active, it is impossible to answer video calls in Google Hangouts (clicking "Answer" does nothing instead of opening a new window).
  • (2016-12-28, v:0.0.23) Moshe Katz: Breaks document.write
    document.write normally allows variadic arguments and concatenates them all together. Several older sites that I visit use this. This plugin breaks that because it accepts only a single argument and ignores all the rest of them. Please fix this.
