Strange pagemod issue

Add-ons Development
#1

Hi!

This is my code:

require("sdk/page-mod").PageMod({
    include:"*.freegamehosting.eu",
    contentStyle:"a[onclick*=\"document.cookie\"] {background:red !important}",
    contentScript:"console.log(\"test\");"
});

For some reason contentScript doesn’t work at www.freegamehosting.eu but CSS is applied well. i think there’s nothing wrong with the code, it works on other domains, with http and https. Does anybody has a clue why it doesn’t work?

#2

Is the site using frames maybe?

#3

no iframes. in that case css wouldn’t be applied either, but it is.

#4

can someone please try the code and tell me if the issue really exists?

#5

I see “test” getting logged multiple times, seems to work.

#6

I see it too, everywhere except on the homepage before i click “accept cookies” button, and that’s the only page where i need it to work. can you please confirm this or does it work there when you open it?

Why didn’t you say that before :expressionless:

It does indeed not work on the “accept cookies” page.
Something fishy is going on here.
When I go to their page from a fresh new tab, the url bar gets cleared and window.location gives “about:blank”.
Maybe they are messing with the history api or something.
They don’t seem to be playing nice.

Well, I didn’t notice it before :innocent:

I found out what stops the pageMod: window.stop() function, here: https://www.freegamehosting.eu/js/cookies.js

When removed, it works fine. Perhaps it shouldn’t have any effect on javascript running inside addons, so this behavior may be a bug.

btw, is there a way to run some javascript earlier? ie, i’d like to set a cookie before website’s cookie checking script runs. as far as my knowledge goes, i can only manipulate it after.

I think you should check this out:

And the sdk has a nice module for matching the address:
