Chromium And Ad Blocking

Advertisement blocking in Chromium isn't as effective as it is in Firefox because extensions can't prevent the browser from downloading and displaying the advert. The best an extension can do, is remove the avert after it has been rendered, which means in the worst case, you will see the ad briefly. While this is better than nothing, it hardly qualifies as blocking the advertisement. For one thing, fetching the advert is sometimes the slowest component when downloading a page. There are other reasons for running ad blockers other than simply hiding them. The Chromium extension API is still new so hopefully this limitation will be removed sometime in the future.

Google Wave And NoScript

One nuisance that I've encountered with Google Wave preview, is that some extensions and NoScript Firefox addon don't get along too well. The extensions are not hosted on Google's servers which triggers NoScript's cross site scripting blocker, unless you add that server to NoScript's whitelist.

Wave's developers will need to address this. While it is only a nuisance now, as more extensions become available, it will become a security problem. Having to whitelist every third party extension site is an opportunity just begging to be exploited.
