May be a memory leak. After sending the last email I saw that FF was using ~2GB of memory. Now, after running for 20 minutes and not using TBB at all, it is consuming ~1GB of memory and slowly growing.
Thanks. I tested a bit and the ASan build has a slowly growing memory consumption right from the beginning but only until it reaches ~1GB for me. Then it is stable (I compared that with recent ASan nightlies made by Mozilla and they are using ~1GB as well). This holds for just opening Tor Browser/Firefox. While opening web pages leads to a growing memory consumption I don't see ever-growing memory usage due to it.
(Note, though, that the memory consumption of Tor Browser seems to be higher than the one visible with the Nightly. That might be due to Mozilla's ongoing efforts to shrink Firefox' memory usage or due to an underlying issue in our build.)
