I don&#x27;t understand what happened to Firefox or how they so comprehensively lost their direction.<p>The whole rationale of the browser was to be something small, tight and easily extensible and to get away from the unreliability of Netscape.<p>Now we learn they&#x27;re deprecating full themes, changing plugins to be more limited (but again becoming more like Chrome), and filling the browser with pointless at best features.  I can&#x27;t recall ever wanting to share browsing.  Screens when coding or helping sure, but it&#x27;s a solved problem, so keep it and the kitchen sink out of the browser.<p>It&#x27;s probably why its becoming so slow and flaky.  The two key problems it was intended to fix.
