This is from a TBPL tab which was left open for a couple of days, without me even using it.

Note that this is the first time that I'm seeing a web page using more memory than a system compartment. This was the biggest memory hog in my profile among 50+ tabs.

Some basic info here would be good: any add-ons installed? There was something else I was going to ask as well, but I forget now.

I'm going to run another instance of the browser using a clean profile with two TBPL app tabs to see if I can reproduce this bug there too.

Open about:home and leave the app tabs in the background. 4. Wait!

Closing the app tabs causes the memory to be reclaimed. I'll try keeping these open in Chrome and see what happens too.

Can you reproduce this with http://tbpl.allizom.org/?usebuildbot=1 too?

(In reply to Markus Stange from comment #8) > Can you reproduce this with http://tbpl.allizom.org/?usebuildbot=1 too? Yes. I did some more experiments. If I reload all of my open TBPL pages, and press the CC/GC/Minimize button at the end of about:memory page several times, the memory usage drops back down. If the TBPL page is left open for a few days, it makes the browser completely unusable. I think the js heap for the compartment just gets too big, and the page starts to show the slow script dialog every few minutes. (I just saw a 650MB compartment for TBPL)
