Canvasblocker: twitch.tv canvasblocker v0.4.0
updated canvasblocker to the latest ver and now twitch.tv wont work. it was fine on v0.3.8. i tried disabled all my other add-ons except canvasblocker and it's still the same. embed twitch.tv player had no problem.
canvasblocker setting is the default setting and i'm using waterfox v55.2.0

I just installed waterfox v55.2.0 and twitch.tv is working fine. Can you be a bit more specific what's not working?

the blank black page. if i disabled canvasblocker with all other add-ons enabled, i can browse twitch but when i enabled canvasblocker, reload the page then the blank black page happened. apparently this only happen to non-beta twitch. i'm still using the non-beta site since some add-ons that i use, doesnt work with the beta site. non-beta is twitch.tv and beta is go.twitch.tv

OK - this is a weird problem. But I can reproduce it and will work on it.

Hotfix 0.4.0.1 is out and should solve the problem.
Please confirm.

I have FF 56, 64bit on Win 10, CB 0.4.0.1 and twitch.tv works just fine.
Block mode: fake readout API
RNG: persistent
Maybe you have a collision with some other extension?
crssi
on 8 Oct 2017
I'm using block everything. (non persistant)
Version 0.3.8 works without problems on twitch.tv, but 0.4.0.0 and 0.4.0.1 blocks twitch.tv complete with a black site, it's the same like you see on the screenshot from astondi. When I downgrade back to 0.3.8 twitch.tv works again.
Osahashi
on 8 Oct 2017
Hmmm, I have switched to your settings and twitch works for me.
crssi

Osahashi
on 8 Oct 2017
Ok, changing to Allow only whitelist = https://www.twitch.tv and twitch.tv works again with 0.4.0.1
Osahashi
on 8 Oct 2017
@Daisenki: this is strange. The "Error: Permission denied to access property Symbol.toPrimitive" is the one that is fixed with the hotfix. But if you can deal with whitelisting I asume it's OK.
kkapsner
on 8 Oct 2017
Not only twitch.tv seams to have problems, also twitter... with block everything tweets doesn't show correct, the links inside tweets are not showing:
Whitelisted:
Block everything:
Osahashi
on 8 Oct 2017
Block readout API works without problems on twitch.tv and twitter web without any whitelist, only the setting block everything breaks it. But why does 0.3.8. work without any problems on block everything and the new versions not? Is it a webExtension issue?
Osahashi
on 8 Oct 2017
Could be a WebExtension issue, the changes I had to make for the transition to a WE or just a bug I introduced.
The problem is that when I'm not able to reproduce the issue I'm not able to fix it...
Can you please create a new Firefox profile, only install CB and see if the problem still occures?
kkapsner
on 8 Oct 2017
On a new profile only with CB it works without any problems on block everything.
So ok, it's no a conflict with any addon, it works with a clean profile, it must be anything at about:config. Any ideas?

I seem to be having the same problem
Switching media.peerconnection.enabled to true makes Twitch work again. So a combination of Canvasblocker, disableing WebRTC makes the site not load.
EchoDev
on 9 Oct 2017
Ah cool thank you! Can you work with that info @kkapsner and fix the problem? :/
I really don't want to activate WebRTC...
Osahashi
on 9 Oct 2017
I have WebRTC disabled and also media.peerconnection.enabled = false, and twitch.tv works as it should.
crssi

It's weird that you don't have that problem crssi, but now with EchoDev I'm at least not the only one with it. :D
Osahashi
on 9 Oct 2017
@Daisenki did you test Twitch with WebRTC enabled to be sure the problem is the same on your end?
EchoDev
on 9 Oct 2017
@EchoDev unfortunately it's not working on my Firefox, I enabled WebRTC complete, reset WebRTC to default, but twitch.tv doesn't load. :(

Additionally WebRTC is disabled also over uBlock Origin.
Maybe this would be the base to start from to find out the diffs you have.
Cheers

The WebRTC blocker in uBO is disabled like always.
Most of the settings are the same on my end, except for OCSP true, memory cache true but both does nothing about the issue. I know the guys from ghacks^^

CB does not do anything with WebRTC...
@Daisenki: can you give me your prefs.js? Maybe I'm able to reproduce the problem with it.

Hotfix 0.4.0.2 is out and hopefully twitch is now working.
kkapsner
on 10 Oct 2017
The 0.4.0.2 fix twitch.tv, it works now the block everything! :)
But unfortunately the twitter timeline is still broken with block everything. Should I make a new ticket for twitter?
Osahashi
on 11 Oct 2017
Yes, please open a new ticket (please add all relevant data like URL, error messages, etc.). I think this is a different problem - @Thorin-Oakenpants seems to have the same problem: https://github.com/kkapsner/CanvasBlocker/issues/127#issuecomment-335026696
