This problem seems to have been fixed (for me) by doing a complete update
('dnf update' in Fedora 22).

I later reported that switching to another CTWM desktop/workspace and
back (using two key presses with my setup) was a usable work-around: it
always seemed to restore keyboard input focus as expected.

It seems that my problem was connected with my reluctance to shut down and
restart linux. Instead I use pm-hibernate and resume. That means that I can
use a lot of material on my 12 ctwm desktops as workspaces with partly read
and partly written things or items to read when I get time.
This also means that I can regularly update many things, including
browsers, but not the kernel. (As far as I know it's impossible to restore
a desktop across kernel update and reboot.)
Today, after about 150 days without rebooting, I decided it was time to
update everything, including kernel, and reboot.
I am pleased to report that this seems to have fixed the keyboard input
focus problem on both my fedora 22 machines (desktop and laptop), tested on
firefox, opera and google-chrome.
Presumably by updating some things and not others I was causing some window
manager mechanism to stop working properly. Normally I would expect that to
be prevented by explicit dependencies that are checked when software is
installed/updated, but this particular dependency may have gone unrecorded.
Anyhow, during a few hours of use since the update and reboot, I have not
seen any sign of the old text input focus problem, using (mostly) firefox,
opera and google-chrome.
I am puzzled as to why such a problem affected only web browsers, but not
other software, e.g. Libreoffice.
Apologies for wasting time with a false alarm.
