Firefox Beta on old LG P500h

Working with Firefox Beta on an old phone:

LG-P500h

running android 2.3.3 (carrier's latest for this phone)

unsure if it even meets the new low end firefox OS hardware requirements...

Notes:

using this phone in a "voice only" mode, just for calls; on a prepaid service.
for data use wifi only.  Have turned off the cell data .

phone has limited memory; do occasionally get an out of memory error when trying https+search on google

like addons
** Adblock Plus working !!

not so sure about apps yet;
installed a game, and wikipedia;  seem slow to start, wikipedia not much different than just the mobile site;  Game's UI a bit slow and unresponsive on this old phone.

tabs:
work well, do keep only a few open, not trying to stress out with dozens open...
