Sandboxie Support

Fonts look a bit thinner at 2.

Some fonts look a bit worse at 2 & 3.

Firefox Nightly is now using security.sandbox.content.level at Level 4. Sandboxie is incompatible with it.

Windows 8.1 Pro x64

Same problem here.

It's working fine now. Thanks!

Hi Barb, Windows 8.1 x64, Sandboxie 5.16 x64, Firefox 51.0 x64, no AV, Firefox installed (copied) manually (from a zip file). Firefox 51.0 (soon to be released) displays blank pages (tabs) when Electrolysis is enabled. Pages are visible when a browser window is resized or when switching tabs, though...

I just discovered that there's a conflict between Sandboxie nad Firefox's own sandbox because Electrolysis seems to work fine with security.sandbox.content.level at 0.

Could you add support for Electrolysis in Firefox?
