Previously, when the chrome sandbox was in burpbrowser/0.144, setting the suid bit and the owner of the chrome-sandbox binary to root:root allowed the embedded browser to work normally. Other possibly relevant context: userns is disabled, but supported by the kernel. Where as I can run Cygwin outside of a Sandboxie sandbox and I will not have permission issues. I am having insufficient write permission when running Cygwin in a sandbox even when I am running the Sandbox as Administrator. Running as root without -no-sandbox is not supported. Insufficient write permission when running in Sandboxie. Setting the owner of the chrome binary to root:root and the permissions to 4755 results in the following error in the embedded browser health check: I'm running Windows 7 Ultimate 圆4 with an older version of Sandboxie 3.64 (64-bit) - haven't changed anything in a while because it's always worked fine with the original settings I made it with - I'm afraid to update to a new version for fear of losing my settings and having to figure out how to get steam working again properly, re-download. Similarly, the install was done as a non-superuser. Burp is running as the now-default non-root kali user. If you want to live dangerously and need an immediate workaround, you can try using -no-sandbox. No usable sandbox! Update your kernel or see for more information on developing with the SUID sandbox. The embebbed browser not work on Kali Linux, I test with health embebbed browser:
