Enabling Click To Play Extension in Firefox

    Does anybody know if this can be done in Chrome?

  2. Midnight

    Already enabled in Firefox Aurora and Nightly!

    Great idea from Mozilla and a good way to avoid all the unwanted Multimedia.

    I’m still new to computers up. how do you navigate to to about:config.

  4. Angel

    When you apply this to your browser, will it affect all Firefox users on that PC?
    If so, is there a way to apply it such that it only affects the browser instances of the user who wants it?

    Al, On the address line, where you see the URL, like, just clear the field and type in “about:config” without the quotes.

    To navigate to about:config open Firefox. Next go to the address bar (where you enter Instead of typing type about:config

    Great tip! And yes, You can do the same thing in Chrome. I have done it, but don’t remember the steps. It was definitely in the config settings. Sorry I can’t be more help on it.

    I was getting “click to activate plugin” on a few sites. Thanks for the helpful walk through.

    I still prefer flash block to this method. But it’s still good to know.

    Firefox 8.01 does not have that option listed.

    You can do the same in Chrome. Go to Settings, click “Show advanced settings”, under Privacy click on “Content settings”, under Plug-ins change the option to “Click to play”. You can also setup exceptions for different sites.

    “Firefox 8.01 does not have that option listed.”
    It’s new with Firefox 16.

  13. Mike

    the same can be done in SeaMonkey, a sibling of Firefox

  14. Neko

    One word: Opera

  15. spike

    @Neko: that’s three irrelevant words.

  16. Taylor Gibb

    @Neko Seriously ? Are you an Opera developer ? Because last time i checked they were the only ones using it :P

    While this option may be a good thing, it is causing problems for me with McAfee SiteAdvisor and KeyScrabler Pro. When this option is active, SiteAdvisor and Keyscrambler stop working properly. I had to “turn off” this option.

    I like how it kept Youtube from blaring out unexpectedly and it worked well.
    Unfortunately, it blocked downloaded PDFs from displaying. I noticed that Noscript has a noscript.smartClickToPlay setting and it was set to True. I wonder if this caused a conflict so the PDF wouldn’t display. If I can get PDFs to work with it, I would definitely use it.
