just got 3.14 upgraded to 3.15 earlier today and found that after this no plugin appear in the plugin tab anymore. I'm not talking about extensions but plugins, flash, Picasa, Quick time, Java, Silverlight etc...the plugin tab is absolutely empty. As soon as I revert to 3.14, they're all back.
 Okay, I took a look in about:config and found that plugins were indeed completely disabled; just changed the value (of "plugin.disable" to false the value and they load again). 

Reproducible: Always
Version: unspecified → 3.1
Yes, that was introduced by bug 599119, and you found already the preference to switch off the off switch. Apparently that was done for performance reasons, I can't find any bug referring to security/content-policy issues mentioned in the release notes as a warning though.

We decided not to.
yeah honestly I'm wondering why they did that... can't see anything in terms of performance affecting my Thunderbird install here when plugins aren't disabled. Would have thought that they did that for security concerns instead but since there's nothing mentioning that either...okay, wouldn't mind some comment on that from a Mozilla dev.

It's very visible on windows - more than any other platform.

How about you start reading bug 599119 which explains why we did it.
look if I'm asking that's precisely because I can't see anything confirming this performance impact (s) on my system, opening messages, new tabs, going from mail to mail with preview on, whatever the action, whatever the content... it doesn't happen here.  And no need to be rude, what do you think I did after the first comment here but read this https://bugzilla.mozilla.org/show_bug.cgi?id=599119... >>> but never mind, it's only a setting.
marking as resolved and I doubt there's anything more to expect from this thread.

That might be true (possibly because your computer is fast enough), but we have plenty of reports and evidence of major slowdown. Thunderbird 3.2 will come with a fix that doesn't involve disabling plugins, but we decided that fix is too risky for 3.1.

okay, no problem as long as the option is available anyway. Thanks for the feedback ;)
