Sandboxie Classic greater than v5.49.8 breaks Internet Download Manager integration in Firefox

[arie93]

Describe the bug
When I run Firefox in the sandbox and download files through IDM, the IDM application does not run at all. I also already added Internet Download Manager in "Software Compability", and still doesn't work.

To Reproduce
Steps to reproduce the behavior:

1. Install Sandboxie Classic
2. Run Internet Download Manager
3. Add Internet Download Manager in "Software Compability"
4. Run Firefox in default sandbox
5. Download the file link from firefox

Expected behavior
Internet Download Manager doesn't launch at all to download the file. So, the file just downloaded with firefox.

System details and installed software (please provide the following information):
OS: win 10 x64 v1809
Firefox: v89.0.1 x64
Internet Download Manager: v6.38 Build 21
Sandboxie Classic: > v5.49.8
No antivirus or any other security software

Behavior tested and confirmed.

what is the last version it worked in?

what is the last version it worked in?

v5.49.8, without any doubt.

[DavidXanatos]

ok so its broken since we added

[Template_InternetDownloadManager]
BlockPort=1001

because an other user complained that it opens an unsandboxed download agent.
we should split this template then or something

[isaak654]

I would suggest a way to customize BlockPort per process, while making sure to test it for Chrome too: #791
Unless you think it's needed another implementation.

[DavidXanatos]

"customize BlockPort per process" with the new WFP based filter we could have this indeed

[isaak654]

As a temporary workaround for this issue, there are two ways:

1. Removing in each new release this line from the Templates.ini file in your sandboxie folder:
   

   Sandboxie/Sandboxie/install/Templates.ini

   Line 2912 in a4e6b49

   BlockPort=1001

2. Alternatively, it's enough to disable the compatibility template and pasting this line in your sandbox section:
   OpenClsid={AC746233-E9D3-49CD-862F-068F7B7CCCA4}

I don't think it's wise to create a temporary template elsewhere that could be forgotten.

BlockPort=1001

Removing that line just fixed this IDM integration in Firefox on the latest Sanboxie classic version.

Info: IDM integration is still NOT working in Firefox or Chrome/Brave and it also dosen't matter to keep or remove the "BlockPort=1001" line from the template.ini file.IDM is already long time not working in Sandboxie Classic and thats the reason why I have still to use the old version "SandboxieInstall64-v5.45.2".This works but makes trouble with other things.So my goal is it to install and use the latest SBC-64 version but only if IDM will work with it (not yet for me).So could you please check this problem and really fix it?I'am using this config...

Windows 10 x64 Version 20H2 (Build 19042.1110)
Sandboxie-Classic-x64-v5.50.9
# prevetn access to host port
BlockPort=1001 <--keep or remove line = makes no diffrent
Firefox x64 Version 89.0.2
Brave x64 Version 1.27.109 Chromium: 92.0.4515.115 (Official Build) (64-bit)

...just test it again.Thank you.

I would also suggest to apply the recommendations about removing the remaining traces of BlockPort(s): #1085 (comment)
