Hello Techies, facts are these:
my machine is a bit old, it's 2003's, 32 bits. The cpu is AMD Athlon XP 2800+.
My OS is Lubuntu 16.04.2 LTS.
As I got to Firefox 54.0 playing videos became difficult as Firefox often crashes.
I asked Mozilla and what I understood is the crashes might depend on proceeding .mp4 files as Firefox 54.0 uses the SSE2 cpu extension that my machine does not have.
So there could be two solutions:
1. using a particular Firefox release, called Extended Support Release
2. upgrading my cpu's drivers.
(It goes without saying that the third solution could be buying a more recent machine, with a SSE2 supporting cpu, but I would prefer not to.)
You can imagine my question:
is it possible to upgrade the drivers of my cpu? How can I do? Where can I find the new drivers? Who can I rely on?
I guess performing this is highly delicate.
Many thanks and regard
