1555054 - CanvasBlocker blocks some site in current Nightly (Tested OK in current FF67.0-64 bit)

Status: RESOLVED WORKSFORME

(Firefox :: Extension Compatibility, defect)

Description

[Jean-Do]

Attachment: Nightly 2019-05-28.odt contains "informations de dépannage"

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:69.0) Gecko/20100101 Firefox/69.0

Steps to reproduce:

With Ubuntu 18.04-64 and current Nightly as of 28-05-19. When CanvasBlocker is active,

• I tried to access to imgur.com
  or
• try to login in https://wordpress.com/log-in/fr?redirect_to=https%3A%2F%2Fcocyec.wordpress.com%2Fwp-admin%2F

Actual results:

With imgur.com, I cannot see the page in https://imgur.com/gallery

With Wordpress, I cannot login because the page is empty

Expected results:

Imgur: I should be able to see and browse the site
Wordpress: I should be able to login
N.B.: Without canvas or with FF 67-64 bits as of 28-05-19, it works perfectly

Hi Jean-Do!

I was unable to reproduce this issue in the latest Nightly version 69.0a1 (2019-06-02) for Ubuntu 18.04-64 with or without CanvasBlocked.
I was able to see both links that you have been mentioned.

Can you please try to retest this on the latest Nightly Version?

Thanks for your collaboration!

Both bugs solved with the latest version :-)
Everything "OK" now.
