Here’s the skinny:
- Ghostery’s library is getting large (and ever more comprehensive) – we’re up to 486 trackers and 337 cookies. That means Ghosty is working his sheet off trying to scan when you open a page. We did a couple of regex/string matching tricks to make this go much faster, and the regex engine in Firefox 4 gets lots of improvements, so we’re confident things will work better going forward. Lab testing indicates that this versions performs much faster than 2.5.1.
- Previous versions of Ghostery included options for scanning things like images, dynamically included elements, object tags, and embed tags. We left those out of the UI when we updated the options screen… so we added them back, and included the option of looking for redirect chains (one script launches another, which launches another, etc). These features are enabled by default – but if you’re experiencing performance issues, you can pick and choose how you’d like Ghostery to work. Every one of the features that is disabled might give Ghostery a little performance boost, but it also means less comprehensive scanning and blocking.
- Cookie blocking should be used carefully. Like we suggested in the last release post – it’s like turning Ghosty into Rambo and giving him a bazooka. We’ll do our best to make sure that it’s not behaving any way it shouldn’t, but know that sometimes blocking cookies has unintended consequences. If you see strange results on a site, try disabling cookie blocking. Whitelisting the site will not keep cookies from being blocked – we currently don’t have a way to associate a cookie request with a particular browser tab.
- Ghostery now comes with a End User License Agreement – you can see it by checking the “credits” section of the help screen. Ghostery is transparent, meaning that we don’t encrypt or obfuscate the code or any part of Ghostery’s operation – but we do retain rights of distribution and development. That just means we don’t open Ghostery to disassembly and reverse engineering for any purpose other than personal edification, it’s not a GPL or CopyLeft license. You can find the agreement in the Ghostery directory (<Firefox Profile Directory>/ghostery/) or available here.
- We’ve added a lot of features, and changed the UI, and even had some reports of some lost settings. So now is the time to double-check your Ghostery options, and make sure everything is set how you like it. Hopefully that’s all the auditing you’ll have to do this year.
