NoFollow Checker For Safari 5

Dan Cryer — Wed, 09 Jun 2010 09:00:28 +0000

A while ago, I wrote a very simple nofollow extension for Google Chrome. When enabled, it marks all no-follow links with a red highlight. Despite it’s simplicity, it has been downloaded a few thousand times!

So, with the release of Safari 5 and it’s new extensions system, I thought I’d knock together something that does the same thing for Safari. It uses exactly the same CSS-based method that the Google Chrome extension does.

Google Chrome Frame

I’m sure by now, if you work in web development, you’ll have heard of Google Chrome Frame. The plugin for Internet Explorer that replaces the entire rendering engine with Google Chrome, on demand.

Whilst I understand that this is a less than ideal solution, as if a user can install a plugin, they can probably replace the browser anyway. However, they released an interesting update today that makes implementation a little more feasible for site owners. You can now issue the “X-UA-Compatible” string as a HTTP response header instead of a meta tag, meaning your Chrome Frame enabled pages can validate again! It also means you can, to clients that support it, serve appropriate MIME type headers that IE does not support, such as application/xhtml+xml.

The Apache configuration snippet to enable this functionality is as follows, you’ll need mod_setenvif and mod_headers enabled to use it:

BrowserMatch chromeframe gcf Header append X-UA-Compatible "chrome=1" env=gcf

I’ve implemented it on this server, so now any Internet Explorer visitors with Chrome Frame installed going to any of my sites, will see them as I designed them originally – in Webkit.

For more information about this update to Chrome Frame, see this blog post.

Chrome Extension: Ten Blue Links

Dan Cryer — Fri, 18 Dec 2009 16:10:17 +0000

Over the past few years, search engines have been adding more and more content to every search result page. From local listings and maps, to images and tweets. A lot of people find that search results are now too cluttered and it’s difficult to actually see the listings themselves.

I’ve developed a Google Chrome extension that strips out everything in the results area apart from the “ten blue links”, your search results. This includes Images, Maps, Video, Twitter, Site Links and Ads. You can download the extension from the Google Chrome Extensions site.

If you’ve got any feedback, please let me know in the comments.

Google Chrome Twitter Extension: TweetPage

Dan Cryer — Thu, 15 Oct 2009 19:05:36 +0000

I’ve just written another Google Chrome extension, this time a little more complex. It’s a Twitter ‘Tweet This Page’ extension, much like the many available bookmarklets, except this one allows you to tweet directly from within the extension, without leaving the site you’re on to go to twitter.com. You’ll need to log into Twitter the first time you use it, but after that, simply click the button, alter the tweet as you desire, and submit.

You can download the extension here, automatic updates are enabled, so you should get new versions as and when I put them up. Please be aware that this extension is quite rough around the edges, (and quite spectacularly ugly,) so please let me know if you manage to break it!

If you choose to use the extension, please let me know, either by commenting below… or by tweeting this page!

Chrome NoFollow extension updated

Dan Cryer — Thu, 15 Oct 2009 10:14:44 +0000

As a quick follow up to my nofollow marker post, I’ve put up a new version of the extension. It does exactly the same job as the old one, except without the need for any JavaScript. The new extension simply uses the following CSS:

a[rel~=nofollow] { background-color: #FCC !important; border: 1px dashed #F55 !important; color: #600 !important; }

I should really have thought of that in the first place! Want the extension? Download it here.

Google Chrome Extension: nofollow marker

Dan Cryer — Thu, 17 Sep 2009 20:34:48 +0000

I was just playing about with Google Chrome’s extension system, and threw together a very simple one that highlights all nofollow links in pink, as I’d seen a few people using something similar in Firefox. It doesn’t do anything complex, the code is as follows:

var elements = document.getElementsByTagName('a'); var length = elements.length - 1;

for(var i = length; i >= 0; i--) { if(elements[i].getAttribute('rel') && elements[i].getAttribute('rel').indexOf('nofollow') >= 0) { elements[i].className += ' nofollow_has_no_follow'; } }

Google Chrome Dev Channel users can Download and Install it now.
