Firefox slow to recognize inputs after screen unlock

[Javier Perez]

Hi

Has anyone had this problem?

After I unolock the screen,  firefox seem slow to recognize mouse or
keyboard input. There is a period of about three minutes where no matter
what I do it will not register with firefox (switch tabs, try to click on
link, etc.).

I can switch and move windows, and terminal and other programs recognize
the input without problems.

I am using Fedora 24, XFCE ( but I think something similar happened also
with KDE.
Linux 4.7.4-200
Firefox 48.01

How can I start troubleshooting this?

I haven't, but I don't lock my screen.

You could search for the problem or open a bug at

https://bugzilla.mozilla.org/enter_bug.cgi#h=bugForm%7CFirefox

When I searched on "slow response", and sorted by id, latest at top,
there were several bugs that looked like possibilities, though none
mentioned unlock that I saw.

The other thing is that firefox 49 should be available soon in the
Fedora repositories, if not already, and it might fix your problem.

Thanks. I will check

I have seen this on several different systems (Linux Mint 18, macOS El
Capitan) so it seems to be a firefox 49
"feature".  My guess is that firefox or some add-on is waiting on the
network.  More and more sites are using https
which I find often makes site less responsive.

Have you tried "restart with add-ons disabled"?

I just updated firefox to 49 and i am testing around. I think my firefox
"smelled" my complaint and is behaving decently for the moment, I haven't
have the problem yet again even before I upgraded to 49. I'll keep
monitoring it.

Try running top in a terminal and see what state the firefox process is 
in.  It might be partly swapped out, in which case it will spend a lot 
of time in the D state.  Sorting by memory usage might help as it won't 
be using much CPU time if that is the case.
