1682373 - Tap-to-right-click on Linux native titlebar is broken

Status: RESOLVED INVALID

(Core :: Widget: Gtk, defect)

Description

[Ryan Hendrickson [rhendric on GitLab, GitHub]]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

1. Have a touchpad
2. In OS settings (I'm using GNOME), enable tap-to-click
3. In Firefox, set the browser.tabs.drawInTitlebar hidden preference to false
4. Use a two-finger tap to right-click on a titlebar

Actual results:

Nothing.

Expected results:

The menu that displays when the titlebar is right-clicked should appear.

Note that the menu does work when right-clicking via other means (using an actual mouse instead of a touchpad, or when clicking with the physical touchpad buttons). Two-finger tap still works as a right-click everywhere else in the Firefox UI that I've tried. And Firefox is the only application I've tried where two-finger tap doesn't work in the titlebar; I've tested with applications that have and don't have client-side decorations.

I'm using the firefox-developer-edition package on Arch Linux, if either fact is relevant.

My bad; I thought I had tested non-CSD applications but it appears I was mistaken. Having done a more thorough test, it looks like any windows without CSD are affected and thus this is a GNOME issue rather than a Firefox issue.
