It is cool that there are now add-ons for IE7 which now give me functionality similar to that I already have in Firefox 2 (in many cases added with add-ons as well).
Unfortunately I couldn’t find an equivalent to my all-time favourite Firefox plugin, AdBlock and even more disconcerting is the fact that many of the IE plugins are commercial (i.e. not free!). Why would people pay for plugins for IE7 when similar plugins are available free for Firefox? Is it simply ignorance?
