Some functions and pages on Bricklink.com do not work while this extension is enabled, particularly pages like my wanted list when logged in to an account, it blocks the website from displaying anything and leaves a blank page. There are likely other websites that I also had issues with that I never traced back to this.

breaks kayak.com
The extension hasn't been updated for 3 years now. So, let's assume it's abandoned.

This add-on can cause some websites to be inaccessible,and there is no way to rule it out.If i must turn on/off the add-on manually,it will be more annoying than advertising.

There are still plenty of sites that give "disable your adblocker messages", plus having this addon active causes some sites to not load/login correctly (one example is xcel energy's my account/bill pay page). This addon causes more problems than it solves and has been deleted from my computer.

Doesn't block many anti-adblocks
