Arch Linux

Description:
It started after I installed the packages "orca" and "espeak-ng". The accessibility feature toggle on the SHIFT+F12 panel is greyed out, claiming it cannot turn it off because it is being used outside the developer tools. I could not, however, pinpoint what is supposedly using it.

Things I've tried:
- Reboot
- Confirmed that Orca is not running, nor it is started on boot
- Killed the dbus-daemon process and reran Firefox: "/usr/bin/dbus-daemon --config-file=/usr/share/defaults/at-spi2/accessibility.conf --nofork --print-address 3". This process is spawned again by Firefox in its startup.

Additional info:
* Firefox package version: 78.0.2-1
* Orca version: 3.36.3-1
* espeak-ng version: 1.50-2
* dbus version: 1.12.20-1

I have attached the journald log. If a more specific log file is needed, I'll promptly provide it.

Steps to reproduce:
1. Install Firefox
2. Install packages "orca" and "espeak-ng". I had also installed the package "espeak", but later removed it.
3. (not sure if needed) Enable accessibility features in the SHIFT+F12 panel. Try doing this and restarting Firefox if it doesn't reproduce the problem straight away.
