CHN: EasyList China will cause the firefox hanging on some website

[orsmile]

When I open the http://www.lolking.net/guides/290336 , Firefox will hang.

If i don't use the CHN: EasyList China, the firefox is regular.

Firefox version : 36.0.4
OS:Windows 8.1
CPU:I5 2500K,E3 1230V2

I test the other 2 pc, cpu is g1820 and i5 4460 (haswell architecture)

it can't reproduce.

maybe this is the firefox issue?

There are two URLs on that page which are 870745-character long...

That's the problem...

[gorhill]

The URLs start as follow:

http://lkimg.zamimg.comimage/jpeg;base64,/9j/4AAQSkZJRgABAQEASABIAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/2wBDAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQ[...]

And keep going on for 870745 bytes.

There is clearly a bug on the page, you can see it with "View source". It's easier to debug with Chromium, as the whole browser doesn't hang like Firefox (because multiprocess).

So you will have to contact the web master so that they fix their problem, there is nothing uBlock can do.

[gorhill]

Well thinking of it... This is really a crazy edge case, but I could harden uBlock to force it use only, say, the first 4096 character from a URL and discard the rest. Still, the bug is clearly on the page and tthis needs to be addressed by the web master.

ok i will contact the web master
