FF and Sandboxie problem

[tnffuser]

Starting with version 51 Firefox will not work properly for me in Sandboxie.
The only part of a page that will load is the part visible on the screen, scrolling further down and all is blank, refreshing at that level does not help.
Same using 'safe mode'. Running Firefox outside of Sandboxie and all is well.

This started immediately when upgraded to v51 while I was still using the same version of Sandboxie that I was using with v50 when all was well.

I assume this is a Sandboxie problem even if the forum seems to say all is well, but is there some setting in FF that might be preventing it from loading the entire page and not just the portion visible on the screen?
I have used Sandboxie for many years with no problem until v51.

Are you running the latest version of Sandboxie, "version 5.16 ... Released on 16 December 2016"?

Looks good here.

Sandboxie 5.16 (64bit) being used.
It is probably something with my setup, but the problem happened between v50 and v51?
Have to run FF outside of it now.
Chrome, Opera, IE all run fine within.
Also, Comodo's Ice Dragon version of FF runs fine in Sandboxie BUT it is still at V50.
I am using Ice Dragon to post this while running inside the sandbox with addons on.

IMO you have to enable compatibility in sandboxie for firefox, and e10s, more from Barb:

Firefox also looks a bit different in the box - it has a white background on top while outside its grey.

Thank you very much Brummelchen.
Obviously, my searching skills on the Sandboxie forum were inferior at best.

Did this recommended workaround:
set "browser.tabs.remote.autostart" and "browser.tabs.remote.autostart.2" to FALSE
No change.

Then did this workaround even though on the forum it was said to lessen FF's security:
set "security.sandbox.content.level" to 0 from 1 (apparently has something with FF's sandbox)
Success!
BUT, pages now load very slowly with these settings but does load.

Since the Sandboxie devs recognize this problem hope they solve it soon.
Now if I can remember to change everthing back once they do!
