@Ross: Mind trying to reproduce this issue? And if it is reproducible, it would also be good to know whether it is a regression (whether it didn't occur with Adblock Plus 1.8.12).

The issue occurs every time. Even if I just refresh the page.

Could you provide a download link for Adblock Plus 1.8.12, please?

(You might need to disable automatic extension updates first, that Safari doesn't update you to 1.9)

Yeah, I disabled automatic updates first. Tho the problem is still there with 1.8.12.
For example with When I go to that page then the initial view shows up as normal. Now when I start scrolling down the page is just grey (no content other than the background), the number of blocked adds on ABP's icon slowly increases and then about 10 seconds later the page content is starting to show up.

Reproduced. Same when Adblock Plus is disabled on that page, or when no filter lists are used. There is a delay of a copule of seconds before the page content shows up after scrolling.

I looks like the messaging between the content script and background page being slow is causing this, also considering that quite a lot of requests, some with quite long URL, are sent on those pages. So it seems there isn't much we can do here, the way content blocking currently works on Safari.
