Showing the Adsense Firefox Referral Button to Non-Firefox Visitors

There is no point showing the Firefox Adsense referral button to existing Firefox users. I used the following simple PHP code to show Firefox referral button to non-Firefox (Gecko) visitors only.

[php]
< ?php if ( !strpos($_SERVER['HTTP_USER_AGENT'], 'Gecko') ) { ?>

< ?php } ?>
[/php]

Simple huh? :)

Internet Explorer visitors see the Firefox referral banner

Firefox visitors do not see the Firefox referral banner
Firefox visitors do not see the Firefox referral banner

Bug?

I want to keep the code as simple as possible, therefore, it can not do deep browser detection. Safari (Mac OS X) users will be treated as Firefox users as well. :P

Here is the better PHP browser detection script, if you are interested.

  • A nice idea.
    But its only work in a site that got high traffic like yours.
    It will have more variety of user that using different browser.
  • LcF
    my point is "don't show firefox banner to firefox user".
  • i am using that too. but I put the advantages of firefox too! open my page using IE to see them
  • hey/. realy nice idea.. thx man..
  • Yes Lcf......nice idea.
  • this is so useful, i only have the detect IE script, and if i put it up, it seems I'm just pointing to those using IE. I hate opera so much
  • So long as it prompts IE users to download a more stable and ultimately awesome browser. Then I'm happy! Mac users already have decent browsing capabilities ;)
  • Strange, but it is displaying the ad in Firefox too. :lol:
  • This one I'll use on my blog.
