Status: RESOLVED DUPLICATE of bug 1600153

(Core :: Widget: Cocoa, defect, P3)

Description

[Rachel Tublitz [:rachel]]

Seen on macOS, 76.0a1 (2020-04-06) (64-bit) and (2020-04-05)

To repro:

1. Close Nightly.
2. Click a link from 3rd party app. I clicked this link from within a Slack(v4.4.1) message.
3. Nightly opens 2 windows - one for the link I clicked, and another for new tab.

Expected:

I'd expect to see Nightly open one window with one tab for the link I clicked.

Actual:

Nightly opens 2 windows, one of which was completely unexpected.

Hi Rachel, this sounds a bit contextual. Could you help by:

1. Verifying whether this reproduces in a fresh profile (https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Multiple_profiles#Profile_management might help)
2. Visit about:support and attach a paste of it (there's a button to copy to clipboard at the top of that page).

Also, for reference, here is the exact doc I'm linking to (although I really don't think it matters as I just made a new one for testing and was able to repro immediately)

And here is a recording of me repro-ing the problem.

Hmm, this looks like a real bug, but given that Firefox needs to be closed to repro, and to be realistic about when this can get some attention, marking this P3.
