do you find old firefox is better than new one?

[Long Wind <longwind2@yahoo.com>]

i have 52.9.0 and 45.9.0, both for stretch

new one often becomes unresponsive,

and i have to close it and restart it
it often happens when i first start it

maybe some function/service is blocked in China

it seems it's doing something impossible, and takes much cpu resource

but old firefox also face blocking

i can't describe it in more details or reproduce problem
