• QuickTime will not play on a new iMac (it works in Safari and iTunes, but not Firefox)

  I have the latest update of Firefox, the latest version of Quicktime and the last OSX (El Capitan) on the new Mac.

  I also deleted all the history, cache, cookies, etc and restarted.

  I always get the same message - that I need to "Download Quicktime".

  Well, this seems to be a new thing of El Capitan. You need to take special measures to activate the plugin browser according to an Apple support article:

  A small number of Web pages older still rely on the web inherited from QuickTime 7 plugin to play the media. In OS X El Capitan, this plug-in is no longer enabled.

  Source: If your web browser shows that it lacks the QuickTime plug-ins - Apple Support

  The article continues to describe where you can find the plugins and move them to a folder that Firefox will check. This is help on your system?

• The colors for my Google calendar disappeared. I can see with Safari and Chrome, but not with Firefox.

  I use Windows 7. I tried to delete the cookies and cache. Nothing has changed. There is no similar problem with all other browsers: Safari, Chrome or Internet Explorer. I restarted my computer. I had to send this chrome because Firefox does not load correctly your site after many attempts. The colors seem to be rinsed at each site. Is there an easy way to restore the colors?

  Thank you.

  Firefox fits pretty well most of the themes of Windows 7, but in some cases, there may be glitches, particularly with the themes "high contrast".

  You are allowing Web sites to specify their colors or their substitution? This is a setting that you can change in the Options.

  the button Firefox orange (or the Tools menu) > Options > content

  Click on the 'Colors' button and make sure that the box is checked for "allow pages to choose their own colors".

• Tables work in Safari and Opera but not in Firefox

  I have a site of 2 columns with the sidebar on the left and content in the right. I try to make the page resembles a bulletin of the 2 column. The two columns are elastic and I made them 50% of the main container. When I put tables on each side, they appear side by side when I use Safari and Opera. However, with Firefox, the table on the right side is pushed off the page. I have the container main to a certain width and had the sidebar and maincontent 50% width. What can I do with the code or css styles to make them appear next when I use firefox? Thank you very much.

  Hello

  Try disabling graphics hardware acceleration. As this feature has been added to Firefox, it has gradually improved, but there are still some problems.

  You will have to perhaps restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

  Then perform the following steps:

  • Click on the orange top left Firefox button, then select the 'Options' button, or, if there is no Firefox button at the top, go to tools > Options.
  • In the Firefox options window, click the Advanced tab, and then select 'General '.
  • You will find in the list of parameters, the checkbox use hardware acceleration when available . Clear this check box.
  • Now restart Firefox and see if the problems persist.

  In addition, please check the updates for your graphics driver by following the steps in the following knowledge base articles:

  • Troubleshoot extensions, themes, and issues of hardware acceleration to resolve common problems of Firefox
  • Update your graphics drivers to use hardware acceleration and WebGL

  This solve your problems? Please report to us!

  Thank you.

• Our AJAX application intercepts F9 to provide contextual assistance. It works in IE7 +, Chrome, Safari, and Opera, but not in Firefox. Help!

  We did the IE, Firefox, Chrome, Safari and Opera - research looking for a touch of common function which was unused to use to help our application context key - and settles on the F9 key.
  Is there a way to ensure that the key F9 key can be passed to the page - it seems doing nothing in Firefox, but is not passed to the page. -Thanks!

  Firefox does not window.event as IE does. He never has. Modern browsers can pass the event handler inline object. Here is an example. I don't know if older browsers support this (it works in IE8):

  <!DOCTYPE html>
  <html>
  <head>
  <meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
  <title>Test F9 keydown inline handler</title>
  </head>
  <body>
  <p>Try F9<br><input type="text" name="textinput" size="25" value="sample value" onkeydown="keys(event,100)"></p>
  <script type="text/javascript">
  function keys(evt, arg){
    if (evt.which == 120 || evt.keyCode == 120){ // F9 key
      alert("Function passed: "+arg);
    }
    return false;
  }
  </script>
  </body>
  </html>
