15.04: Firefox crashing all the time?

[Paul Smith]

Is anyone else seeing this on Ubuntu 15.04 (Ubuntu GNOME technically)
with Firefox 38.0 (deb 38.0+build3-0ubuntu0.15.04.1)?

I mean, it happens to me about once or twice a day: Firefox just
disappears and I get the "should we report the crash" error dialog.  I
haven't see this happen in years.  It doesn't happen on my system at
work, that I've noticed, running the same Ubuntu.

I have very few extensions: adblock plus, flashblock, lastpass.

I keep waiting for some Firefox update to appear that will fix the
problem, but so far no joy...
