silverlight5.1 works, silverlight5.0 ignored by browser

Asked by Ian Gibbs on 2015-04-01

Firefox 36.0.1

igibbs@office-2 ~ $ lsb_release -a
No LSB modules are available.
Distributor ID: LinuxMint

I have successfully installed silverlight5.1 and seen the bubble test work OK. The service I am trying to access (NowTV) is one of those for which silverlight 5.0 is recommended. I have disabled the 5.1 plugin and enabled the 5.0 plugin, which seems to have worked:

igibbs@office-2 /usr/lib/mozilla/plugins $ ls -l

-rw-r--r-- 1 root root 80576 Apr 1 2014 libtotem-narrowspace-plugin.so

The plugin does not show up in about:plugins. If I switch back to 5.1, it does show up. Running the debug command produces nothing of interest:

(process:4461): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
(firefox:4461): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::sm-connect after class was initialised

(firefox:4461): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::default-icon after class was initialised

It seems Firefox has ignored the 5.0 plugin. When I switched to it, the license agreement was displayed as expected.

Firefox seems to have a problem lately if a plugin takes too long to load and blacklists it. This is especially problematic if you enable a plugin for the first time since it needs to be installed. In case a plugin does not show up, run "sudo pipelight-plugin ---create-mozilla-plugins" and restart your browser.

Can you help with this problem?
