Hello Robert,
I had EXACTLY, exactly the same problem on a fully updated F25 system, a
couple
of weeks ago.
Unbearable. But in my case even libreoffice and kate were very slow.
I solved the problem brilliantly by... switching (also for other
reasons)
to Ubuntu 16.04LTS. Not 100% good, but much, much, much better from the
point of view of this post.
My highly unscientific opinion is that there is something in the F25
COMBINED, default configuration of:
firefox+javascript+flash+X.org/graphic drivers+qt+whatever...
that makes everything loop, at EVERY user action, until some timeout,
somewhere
deep in the kernel, makes thing restart. Every 100 milliseconds or so.
Since I don't have, in this period, neither the skills nor, above all,
the TIME
to investigate all this, I blindly tried the dumbest, and brutest
approach, that
is change distro. It worked beautifully, so for the time being I'm just
a Fedora
observer (because I do like the distro), but not a user. Hope to come
back to Fedora someday.
What I mean to say here is that all browsers suck, and Firefox likely
sucks more
than others. But in some conditions, that is with certain combinations
of distro,
kernel, graphic drivers... it sucks immensely more than usual. I mean to
say that
maybe the question you should ask (and people with the right skills/time
should
investigate) is "why is firefox ON FEDORA so slow"?
HTH,
Marco
