Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect, P3)

Description

[Peter Magyari (Desktop QA)]

Affected platforms:
All

Steps to reproduce:

1. Launch Firefox
2. Navigate to this link
3. Start playing the video on the page
4. In a new tab, navigate to about:config and add the following pref as boolean and set it to true: "media.gmp.plugin.crash"
5. To back to the tab from Step 2

Expected result:
The plug-in crashed infobar is triggered and has a "learn more" hyperlink

Actual result:
The plug-in crashed infobar is triggered but it has no "learn more" hyperlink

Notes
The issue is reproducible all the way back to Nightly 82.0a1 since it is a regression from Bug 1660608
This issue occurs with both Proton set to on/off

The

notification.messageText.appendChild(new Text(" "));

call at https://searchfox.org/mozilla-central/rev/5a8487d8e9dd114289083800f723d9c56c9a8003/browser/actors/PluginParent.jsm#212

produces

NS_ERROR_FAILURE

with no message (ugh). I have no idea why off-hand. The regression window appears incorrect, because the 2020-08-25 nightly still has a "Learn more" text. Peter, can you re-check? I suspect bug 1661043 which landed a few days later.

Romain, this predates proton by 6 months, does it really need to be P2b?

Comment 3

[Romain Testard [:RT]]

AGreed that given this is not a proton regression it should not be prioritized over proton polish items. Marking a P3

I've re-checked and you are right, it seems like Bug 1661043 was the culprit after all, my bad there.
