Opening LibreWolf from the taskbar prevents non-sandboxed links from opening in it

[Dyras]

Describe what you noticed and did

0. Install LibreWolf outside of Sandboxie and force it to run inside of Sandboxie
1. Click the LibreWolf shortcut in the taskbar:
2. Open Skype and try to click a link. Notice how a new LibreWolf.exe is started inside Sandboxie, and then it's immediately terminated:

3. Close LibreWolf
4. Click the link in Skype or any other program
5. Notice how it now starts as it should, every time.

How often did you encounter it so far?

Whenever I open LibreWolf in the taskbar

Affected program

Where is the program located?

The program is installed only outside the sandbox.

Expected behavior

It should always open the link, and it should work every time

What is your Windows edition and version?

In which Windows account you have this problem?

User account with UAC protection set to Always notify.

Please mention any installed security software

Windows Defender

What version of Sandboxie are you running?

Sandboxie-Plus v.1.8.1

Is it a new installation of Sandboxie?

I just updated Sandboxie from a previous version (to be specified).

Is it a regression?

Gonna check on this later

I can confirm it also on a new empty sandbox.

Probably, but I doubt it's relevant

(The last line was added by me after this started happening in an attempt to fix it)

It may be because it starts working under the default desktop (Winsta0\default) when launched from the taskbar. Do you have the same problem when running LibreWolf.exe directly? (with Force template selected)

Also you can try creating a shortcut for LibreWolf via Sandboxie and pinning that shortcut to the taskbar. Right click on the sandbox > Box Content > Create Shortcut > Find and select LibreWolf.exe

There seem to be other similar issues as well.

@offhub When I run LibreWolf from CMD, it works When I run it through a shortcut, it works.

So yeah, it seems to be an issue with the taskbar specifically.

[wilders-soccerfan]

@Dyras In your [LibreWolf] box, if you change "Enabled=y,User" to "Enabled=y", does it affect anything?

[Dyras]

@wilders-soccerfan No change at all unfortunately.
