Pipelight installs correctly in Chrome but not Firefox

[Ronald McCollam]

Pipelight works correctly in Chrome, but when attempting to launch Firefox the plugin fails. This happens regardless of whether the plugin was installed in Chrome (and thus had .wine-pipelight present) previously.

I created a new user and ran Firefox from the terminal to get this output:

Finally, for more weirdness, Pipelight works fine for me on another machine running the same version of Ubuntu. Copying ~/.wine-pipelight and/or ~/.mozilla over to the broken machine seems to have no effect. Likewise with purging and reinstalling the pipelight packages.

Hi Ronald,

One thing which seems a bit weird in your output of dpkg-query --list: We're aways pushing out versions of pipelight and pipelight-multi with same version numbers, and the current one is 0.2.2. I would recommend to check if there is an update available for the pipelight-multi package. Nevertheless I don't think we've changed anything related to exactly your problem, so even version 0.2.1 should work well with both firefox and chrom(ium).

I think your problem is most probably related to AppArmor. This is known to break the plugin installation process (since the dependency-installer script and also wine is spawned as a new process). Please take a look at the following bug report:
https://bugs.launchpad.net/pipelight/+bug/1241513
Answer #2 also contains a description of what you have to modify to work around this issue.

If this isn't the issue please report back. It could also have to do with wrong file permissions, but as it works in one of two browsers this is rather unlikely.

Hi Sebastian,

AppArmor seems to have been the culprit here, thanks! I eventually had to disable it completely as even after allowing the bits through from bug 1241513 I was getting some errors. (Plus disabling it fixed Amazon streaming with Flash as well, which was a bonus.)

Thanks for the quick help on this!

Hi,

I've installed Pipelight from this tutorial http://zecheru.com/how-to-install-silverlight-on-ubuntu-14-04/
Restarted Firefox - no success (still can't stream and see a message that I need to install Silverlight)
Rebooted system - the same thing.
Opened content in Chromium - success.

Please let me know what shall I do to be able to open it in my browser of choice (Firefox).

Thanks.
