1605298 - www.pcgamesupply.com is unusable on Firefox with Strict Enhanced Tracking Protection

Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, defect, P3)

Description

[Nicholas Nethercote [inactive]]

Steps to reproduce:

• Visit www.pcgamesupply.com.
• Click on "sign in" at the top right corner. Nothing happens.
• In Chrome and Safari, a "sign in" dialog pops up, asking for email and password.

This makes the site unusable. I got the same behaviour with Nightly 73 on both Mac and Linux.

Hi, created ticket: https://github.com/mozilla-mobile/fenix/issues/7312 as the issue can be reproduced on mobile as well with Firefox Preview Nightly 191220 (Build #13540608) and GeckoView 73.0a1 - 20191216095052.

This doesn't reproduce for me in a new profile in Nightly. Nicholas, do you happen to have an ad blocker installed?

(I'm not sure it's super useful to file duplicate bugs like this, FWIW. At least not until we understand the issue and determine that Fenix would have to do something separate from Firefox.)

I have uBlock Origin installed. I tried disabling that, but the problem persisted.

I also have Enhanced Tracking Protection on, with some kind of Custom setup. (I don't remember how I ended using the Custom option.) I disabled ETP for this site via the shield icon and the problem went away!

I tried with a new profile. Normal ETP is fine, but Strict ETP breaks the site.

The site (including login) appears to be working fine now in strict mode/private browsing windows.
