Mozilla Firefox dont start properly (no windows) while sandboxed

Hello everyone,

since a few weeks now i have a strange problem and nothing worked that ive tried.

Im using Windows 10 64-Bit (1903 since today; but problem also was here with 1809), Mozilla Firefox 67.0.1 64-Bit (but problemw as also there with earlier versions) and Sandboxie 5.30.

Problem stil exists even with disabled Add-ons and after deinstallation/reinstallation of FF.

I start FF either from Sandboxie (Start Web browser) or directly (setting is "start always in Sandbox). I can see in task manager that there are several FF processes; but i dont see the FF GUI. Outside of Sandboxie FF starts without a problem.

Sometimes, when i have started FF outside Sandboxie suddenly something will be opened in FF sandboxed (maybe i clicked a link in a different application).

Any ideas?

Greetings

 

Thomas

 

  • Hi Thomas,

    Start by deleting the contents of your Sandbox, and then if needed, testing in a new Sandbox with default settings.  

    If the problems persist, please, provide all the info as per guidelines so that we can test and assist you:
    How to report problems with Sandboxie

    Adding to the above listed, also include your configuration file:
    Configure--> Edit configuration
    Copy-paste the contents here.

    Thanks!

    Hi,

     

    new Sandbox didnt help.

    Here are my details:

    Windows 10 Pro 1903 (problem exists also prior update)

    Mozilla Firefox 67.0.2 64-Bit with the following extensions:

    - uMatrix

    - Turn off the lights

    - HTTPS Everywhere

    - Decentraleyes

     

    GDATA 25.5.3.4 (Web Protection is disabled)

    Starting FF outside Sandboxie works; inside Sandboxie it starts, but no GUI visible

    Hi Thomas,

    Do other browsers start Sandboxed?
    Does the issue happen for both your user account and your admin one?(You have 2 users listed in the output)

    A few things to try:

    1 - Remove all the FF extensions (probably easier if you create a new Firefox profile under the current user) -> delete the contents of your Sandbox --> retest

    2 - If the above fails, with the new profile and an empty Sandbox do the following:
    Configure --> Software compatibility --> Find your GDATA template, remove it. Re-test [Try the same with the nVidia template if needed ]

    3 - If all fails, try removing your AV for testing purposes, reboot , delete the contents of your Sandbox and re-test (once confirmed whether Firefox works or not, please re-install your AV software - If it works without your AV, you'll need to find out exclusions for Sandboxie, here are some examples based on other antivirus software, exclude Start.exe""License.exe""SandboxieBITS.exe""SandboxieCrypto.exe""SandboxieDcomLaunch.exe""SandboxieRpcSs.exe""SandboxieWUAU.exe""SbieCtrl.exe""SbieIni.exe""SbieSvc.exe").
