I have notices that it can make several pages blank. The site loads but either it's blank or corrupted.

Good idea but essentially unusable in its present implementation. It makes a large number of websites mostly or partially unusable, sometimes starting right at their login pages. This needs an adjustable global timeout, and per-site timeout adjustment. E.g., if a slow site sometimes takes 20 sec. to load, I would want to set maybe a 40-sec. timeout for elements on that page, and not block any of them unless they take longer than that. For a site that almost always loads in 3-5 sec., I might set it at 10 sec. (That extra padding will account for my typical VPN usage.) I can't tell what the defaults are, but I'm guessing around 5 sec., since this breaks even pretty basic and quick-to-load sites like LastPass.com (was able to login, but the script to create a new entry from the "+" icon apparently takes a hair too long for Block Unreachable Scripts, so this basic function of the site can't be used at all with this extension enabled (not that I'll be using LastPass much longer anyway, but it's just one example of breakage).

Very good, but needs some adjustment. Clicking on signup on stackoverflow.com and then picking google, this script will prevent from reaching google.

在这样的环境还有国产的插件，绝壁支持啊。 有没有类似page load time的插件啊，这插件看的不是很懂，能看到DNS解析时间，方便调整分流DNS
