Pinning tabs is very bad for YouTube because they are always rendered and thus always leaking.

Can you elaborate on this? What does "always rendered" mean?

[chupasaurus]

Basically they have a higher priority than regular tabs, mentioned here [0] in context of unloading and the same applies to execution scheduling.

Interesting. Does this mean I should tell users to avoid pinning tabs when browsing in the Tor Browser Bundle? (Assuming they have set the slider to "safest" to disallow JS)

[chupasaurus]

With JS disabled only media files could cause a memory leak, so the "safest" option covers that.

Thanks!
