Sandboxie + Firefox = 100% CPU USAGE

[PhellipeLuthor]

Hello everybody;

I'm using iMacros software to extract data from a particular site, but when I opened more than one browser simultaneously... it is caused conflicts ... the solution I found was buying Sandboxie and running the script in iMacros for each open browser in a box different.

The problem is that I need to open about 70 browsers and place the macro to extract data in each browser open, and I'm not managing to even get close to it. With only 8 browsers open the task manager shows that the processes with firefox + SandBoxie are using 5 GB of RAM and 100% of my CPU 8GHz (Xeon E5-2620 @ 2.00GHz x 4 cores).

I do not understand why Firefox browsers are consuming both performance when opened with Sandboxie ... is there any solution?
