Firefox ignores keyboard when acroread running

Posted

When acroread (9.5.5, but this has happened for years with many versions) is running Firefox doesn't get any keyboard input. Firefox is full-screen, acroread is in the background, Firefox gets mouse input. This doesn't happen when acroread's plugin is up, only the stand-alone acroread. I do this only occasionally; it's more annoyance than serious problem. I'm more curious as to what's happening.

Hi RandomTroll, This was an old issue on linux: https://bugzilla.mozilla.org/show_bug.cgi?id=419377 However I am not aware of the version of linux that you are using and would help the investigation further.

The bug to which you refer regards the acrobat plugin. I reported a problem with acroread and pointed out that it *doesn't* happen with the acrobat plugin.

When I posted the question I included all the information about my system. I use Slackware; I check for updates daily. I build my own kernel, currently 3.18.3. I use Firefox 35, acroread 9.5.5. The problem has happened for years

Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?
