Yahoo's YSlow Plugin

First, some clarification. YSlow is a pluggin for Firebug, not Firefox. It's installed as a Firefox pluggin, but it actually enhances Firebug. Accordingly it requires Firebug to be installed.YSlow adds a new YSlow tab to Firebug and in this tab it rates your page on the scale A to F, based on compliance with Yahoo's performance rules and provides a link to each rule, and lists each component it believes could be improved. Each of these "rules" have their own weighting too.This all sounds good, so I thought I'd put it to the test against my sites to see what it had to offer, and see what changes I could make to improve the overall impression of the performance of my sites.  Continue reading ►

Firefox Gives Away Passwords for Free

Chapin Information Services (CIS) have discovered quite a major flaw in the way Firefox's Password Manager automatically populates username and password fields on a web form.Whilst this is a major time saver, it does however allow phishers to gather usernames and passwords without you actually knowing it, especially on weblogs and forums which allow posters to input HTML. Essentially, they would just create a hidden form that Firefox would automatically populate with your username and password for that site and then submit it to the phisher's server when you click a link or hit enter. This doesn't use cross site scripting (XSS) methods either as it's essentially gathering passwords for the site you're actually visiting (hence most phishing detectors won't pick this up).  Continue reading ►
