Hello @DavidXanatos, latest build installs fine but yesterday I found out about a problem, it seems. I upgraded "Free Download Manager" to its latest release and since then neither the corresponding Chrome-plugin nor the Opera-plugin will intercept downloads any more. Even the right-click-option "download with FDM" doesn't seem to work any longer. So I reverted to the previous FDM-build 6.13.3 - but no success either. Then I tried to start Opera/Chrome outside the sandbox - and suddenly the intercept did work again, even with latest FDM-version 6.13.4. Thus it would appear that the latest Sandboxie-Plus upgrade may have been the culprit and I only did not realize the problem with FDM until its latest upgrade while the problem may have existed with v.6.13.3 and earlier builds as well. Strange thing is - I faintly remember, wasn't there a special global-compatibility-setting in Sandboxie for FDM before? Not sure about that, anyway, it seems gone now. But the issue remains that the corresponding FDM-Chrome/Opera-plugin (v3.0.55) all of a sudden has stopped intercepting downloads since the last or last-but-one Sandboxie-Plus-upgrade while it will work correctly with the un-sandboxed browser. Any thoughts about this problem?
