How to reduce FireFox's RAM consumption?

Question

Browsers

You need to run several (the more the better) Firefox.
In general, I launch each firefox separately from each other with my proxy, then I run the script through imacros and press play. One copy consumes about 200-300 megabytes of RAM how to reduce?
Or maybe there is another way?
There is a script for collecting Satoshi in the net, the more accounts work, the more I collect. Maybe it's possible to run the script in a new window with a different proxy? and cookies and cache? then it will eat less RAM, but it seems like it's impossible. Who has what options who how can help?

Answer 1

disable all unnecessary plugins.

Answer 2

Specifically for Firefox, I can not advise anything, and it is unlikely that this can be done normally.
But I can advise Mem Reduct

Answer 3

I use FireFox Builder optimization , author Mikhalkin Alexander

Answer 4

imacros has a CLEAR command, I used to clean it periodically. But it does not remove all garbage, but only cookies, storage, etc. Firefox itself is legendary in terms of memory ...
Well, and another tip number 2 - turn off "Firefox will remember history" in the settings - it will eat about 2 times less memory.
