Comment 1 Yanko Kaneti 2014-11-12 12:27:38 UTC
no change with firefox-33.1-1.fc22.x86_64

Comment 2 Martin Stransky 2014-11-19 12:09:57 UTC
Can you provide me some reproduction steps for it? I'm unable to launch the on-screen keyboard. Also, to you run gnome-shell or something else?

Comment 3 Yanko Kaneti 2014-11-19 12:13:59 UTC
Yes this is under gnome-shell.
- go to control center -> Universal access
- enable "Screen Reader" or "Screen Keyboard"

Try to start firefox.

Comment 4 Martin Stransky 2014-12-11 15:58:14 UTC
set GNOME_ACCESSIBILITY=1 does the trick.

Proposing as an Alpha blocker, conditional violation of https://fedoraproject.org/wiki/Fedora_22_Alpha_Release_Criteria#Required_applications - "It must be possible to run the default web browser and a terminal application from all release-blocking desktop environments." - when a11y is enabled, somehow, which seems relatively easy to do.

Comment 7 Martin Stransky 2014-12-15 08:44:44 UTC
A workaround which temporary disables ATK in Firefox just hit the rawhide, package firefox-34.0-8.fc22.
