Bug Description

Onboard does not proffer any suggestions or (one assumes) learning from input for XUL based software (e.g. Firefox and Thunderbird). At this point whether similar bugs are experienced of software based on toolkits other than gtk2/3, or whether this is expected or accepted behaviour.

P.S. I'm almost certain than when I first started using Onboard (from trunk) it *did* interact perfectly with Firefox, proffering suggestions and (seemingly) learning from text input into Firefox. I /could/ be incorrect though; my memory of such minutia is hardly infallible.

Auto-show and word suggestions should both work pretty well in Firefox and Thunderbird, it never stopped here at least. There's even special handling of the URL bar only for Firefox. What distribution is this again?
$ cat /etc/issue

See if you have libatk-adaptor, the Mozilla apps need that one. Ubuntu should have it installed by default, though.
$ sudo apt-get install libatk-adaptor

This is the full set of AT-SPI bridges and adaptors I'm aware of, for Qt apps, LibreOffice and Java apps:
$ sudo apt-get install libatk-adaptor qt-at-spi libreoffice-gtk
$ sudo apt-get install libatk-wrapper-java # only if you have the space and need Java

Yep, it's installed and up to date.

Looks likes this is destined to be /another/ quirk that affects my system and only my system. I'm really not sure what I could have done to down Onboard's compatibility with Firefox. It might be worth noting that I've got the current stable release of Firefox as well as the current nightly installed. I use both regularly, both are affected, and Firefox and Thunderbird were both affected before I installed Firefox nightly.

Sorry for the delay, there was a mad rush to get the 1.0.0 release ready.

Try this first, to be sure:
sudo apt-get install --reinstall libatk-adaptor

One more, this really shouldn't be necessary anymore, but I heard it helped occasionally:
add
GTK_MODULES=gail:atk-bridge
to
/etc/environment

So, do you have any firefox from the regular repository installed or are both, the stable too, from PPA's? Which PPA's? What about Thunderbird? Maybe they aren't built with ATK. I'd like to try them here.

I'm afraid that hasn't done the trick. :-(

Doesn't /appear/ to have had any affect, but I haven't rebooted the system yet. I'll get back to you once I get around to rebooting, should the situation change (otherwise, assume it hasn't worked).

I'm using Firefox *27.0.1+build1-0ubuntu0.13.10.1 (saucy-updates)* from the Ubuntu repositories (universe? partners? I'm not certain which), Thubderbird *1:27.0~b1+build1-0ubuntu0.13.10.1 (saucy)* from the official Thunderbird Beta PPA (ppa:mozillateam/thunderbird-next) and Firefox-Trunk *30.0~a1~hg20140225r170482-0ubuntu1~umd1~saucy* from the official Mozilla Daily PPA (ppa:ubuntu-mozilla-daily/ppa). I also have Thunderbird Daily installed from the latter PPA, but I don't really use it at all.

It finally happened here too, on my updated Trusty Tahr. Firefox became invisible to Onboard some days ago. Francesco told me the same happened on his machine. Orca the screen-reader stopped seeing firefox as well, so I don't believe the cause is with Onboard.
What we all have in common is new versions of firefox. I'll try to start there and see if I can find out where in the chain the accessibility events get lost.

Nope sorry, no bold. Claws mail in plain text here.

This was fixed in Trusty apparently, accessibility for Firefox and VirtualBox is back for me. Apparently Ubuntu replaced gnome-settings-daemon with its own unity-settings-daemon, and the new one initially failed to locate the GTK modules for the various at-spi bridges, i.e. for Mozilla apps, Qt, and probably Java as well.

This won't have any direct effect on Ubuntu 13.10, but perhaps something similar is going on. Lee, when you find the time run this please (while Firefox is running):

$ grep -i atk-bridge /proc/$(pidof firefox)/maps

It should print lines like
/usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libatk-bridge.so

and

$ env | grep GTK_MODULES

which here is
GTK_MODULES=gail:atk-bridge:overlay-scrollbar:unity-gtk-module

Thanks for getting back to me.

As requested:

Doesn't print anything at all, it just returns me to the prompt. (note: thus is running the above command on firefox-trunk's PID rather than firefox's per se)

> $ env | grep GTK_MODULES

prints only GTK_MODULES=overlay-scrollbar. Which is odd, as I had previously followed your instructions to edit /etc/environment to include GTK_MODULES="gail:atk-bridge". In fact /etc/environment presently reads as follows:

   PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
   GTK_MODULES="gail:atk-bridge"

I added the double quotes to bring the GTK_MODULE= line in-line with the existing PATH= line. I figured it wouldn't make much difference, but perhaps it does? For the time being, I'll replace GTK_MODULES="gail:atk-bridge" with GTK_MODULES=gail:atk-bridge:overlay-scrollbar:unity-gtk-module (sans any double quotes) and see if that helps.

Lee Hyde (anubeon) wrote :

I've also executed

$ GTK_MODULES=gail:atk-bridge:overlay-scrollbar:unity-gtk-module

and restarted both Onboard and Firefox, both to no avail. The above modules are of course now loaded (the output of env | grep GTK_MODULES confirms this), but Onboard still doesn't 'see' Firefox (trunk or stable).

Francesco, thanks for the update. I have the same output here.

Lee, I don't think quotes in /etc/environment make a difference either, but better use 'export' in the terminal, else the variable won't reach child processes:

$ export GTK_MODULES=gail:atk-bridge
$ firefox

This isn't necessary when you do it in one line, I think:
$ GTK_MODULES=gail:atk-bridge firefox

Then run this again to check if the module is loaded, good output would be like Francesco's above:
$ grep -i atk-bridge /proc/$(pidof firefox)/maps

If there is nothing, check if this file exists:
$ stat /usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libatk-bridge.so

and try this
$ firefox --gtk-module=/usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libatk-bridge.so

If that fails there should be message like
Gtk-Message: Failed to load module "/usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libatk-bridge.so"

Check again if the module is loaded:
$ grep -i atk-bridge /proc/$(pidof firefox)/maps

Of course, doh! Presumably I don't need to include 'export' in /etc/environment.

Still no joy I'm afraid.

The file exists.

Done, and no sign of a failure to load the atk-bridge (or any other) module.

> Check again if the module is loaded:
> $ grep -i atk-bridge /proc/$(pidof firefox)/maps

Done, and I'm finally getting output (as follows), alas there doesn't appear to be any joy on the word suggestions front. Onboard still appears to not 'see' Firefox (maybe a reboot will help things along; reboots always help things along ;-))

I do have it there, pasted from somewhere else, but I don't believe you need it. Doing this manually isn't supposed to be necessary anyway.

> Onboard still appears to not 'see' Firefox
I think libgail is still missing, try this
$ firefox --gtk-module=/usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libgail.so --gtk-module=/usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libatk-bridge.so

and check if both modules are loaded with
$ grep -i "atk-bridge\|gail" /proc/$(pidof firefox)/maps

If we're lucky that does it, but we don't know why the modules aren't loaded automatically. Some random things I came across that may help finding out:

Output (as follows) suggests that both modules are loaded, but Onboard still doesn't seem to 'see' Firefox (i.e. no word suggestions).

I did notice that when I abruptly kill Onboard (via Ctrl+C in terminal), I get the following output, could it be related/illuminating?
