Internet Explorer 8 only: Internet Explorer may be the least popular browser among our readers, but weblog IEBlog demonstrates how to determine which add-ons are slowing down your IE page loads with a tool we wish other browsers would pick up on.
Internet Explorer 8 added a column for load time to the Manage Add-ons dialog; this shows you how long each add-on takes to load, on average, each time you open a new tab.

The article mentions Skype 4.1 as a known offender, but sound off in the comments if you've found other Internet Explorer add-ons that make tabs load slower than molasses. As for the rest of your browsers—this feature would be invaluable for hunting down your own bloat-inducing extensions. (We're looking at you, Firefox.)
