Listary Search broke in Sandboxed Firefox

[SLowrAM]

Sandboxie v3.74 Win7 x64

I have Listary compatibility turned on and it works aside from search. If I press windows + w and search for an existing file (when a save dialog is opened), it always says file not found - it works fine in nonsandboxed firefox browser.
I doubt this is just related to sandboxed browser, but that's where I experience the problem.
