Re: NVDA-2016.2 Slows Down with Firefox

I haven't noticed this so much with Firefox, but I have noticed this a
couple times over the last few days in the ordinary system. I don't have
heaps of RAM like the person who gave their specs, but I have had this
problem crop up every now and again over the years. Usually, I can
restart NVDA without having to restart the computer, but when it came to
my Braille Display, things would lock up to the point where I'd have to
restart the entire system, sometimes requiring sighted help to do so. If
this hasn't been just me, then all those scans I did last year to try
and make everything run faster weren't effective because it wasn't my
system's fault. It was NVDA not responding. That is, of course, if the
problems are more widespread than I first thought.

with jaws these occurrences do not happen.
I now use the jaws 17 full-time for these reasons.
jaws is not slow in any situation like this occurred with NVDA.

I only use 3 extras.
I do not need anything else.

NVDA is getting slower and every a new version.
this makes me worry.

I think the team of NVDA has to think about this with more seriously.

a while, and only use the others when necessary.

If you have a number of tabs open in Firefox, NVDA will begin to slow
appreciably in the program. Responses to key presses are delayed and
the browser becomes problematic and inefficient. The only solution is to
restart firefox.

manifest--sometimes I could work for a whole day and NVDA would not slow
down until the next.
However, now it barely takes six to ten hours for this slowness to

I do not know if this same slowness occurs in Internet Explorer,

performance, and what--if any--solutions are available to counteract
