Extensions not working in private browing

[weebstriker-coder]

I have found a bug. In Zen Browser, some extensions seem to not be working in private browsing, despite having the permission to. In particular, the extension "uBlacklist" was not working in my private browsing. I first thought it might be an issue with extension updates, so I tried the same with four old versions of the extension, spanning around a year of releases, but all of them did not work in a similar way. I hope this is helpful. Thank you very much!
