I agree. I have same experience. Many times I have been trying to fix it with direct Fanboy help. But sitaution si bad. ..... Same Adblock rules, which works under Opera, Firefox, Arora, Safari ..... often didn´t work correctly under Iron/Chromium/Chrome.
Me and Fanboy (through his Forum), tried many variations, rules, customisations, but not very help.
Iron/Chromium/Chrome have very bad abality in that way. Fanboy said other WebKit browsers (like Safari) have "Style Sheets management" aka CSS.
Within CSS is often able to block those html/js codes, what only Adblock can´t. Iron/Chromium/Chrome are just very bad because lack of it.
There are several add-ons for adblocking http://www.chromeextensions.org/http://www.chrome-plugins.info/en/https://chrome.google.com/extensions/
all works under Iron 4.0.280.0 (its fully compatible with Chrome 4)
but CSS management is extremely ugly behind most of webkit based browsers
Plus lack of features like ....
1) CSS management,
2) RSS viewer/reader/subscriber,
3)Page Print options/Page Setup/Print Preview etc...like remove headers,footers,setting for margins....
add-ons for RSS are not very good, and print settings is not able at all (no add-ons exists)
For me, these are annonying,
but Iron is still my default browser in win7.
In version Iron 5.0 some of these will be fixed
, but not all
