User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:18.0) Gecko/20100101 Firefox/18.0 Build ID: 20130109165101 Steps to reproduce: I used to open > 100 tabs and usually open a bunch of tabs (>20) using the "Open In Tab" in the bookmark menu, It is very slow. Expected results: So it should be loaded on-demand when the items of the menu is large.
> it should be loaded on-demand when the items of the menu is large Not only when large -- I'd like the ability to defer loading of *all* but the first one or two of an "Open All in Tabs" set. I don't *view* multiple tabs concurrently, so loading them all concurrently only slows me down and sterilizes me for no reason.
This should not be bookmark specific. There are addons that may open many tabs at once, and user will expect them to load on demand if the same applies to the "Open In Tabs" scenario.
