Description

I'm using Tor Browser 6.5a1-hardened (verified PGP signature) without modifications, security slider set to high. Simply opening the browser (via tor-browser/start-tor-browser.desktop) mallocs about 250 MB of RAM which jumps to over 600 MB of RAM when the "Welcome to Tor Browser" page loads. If I let it sit idle on the welcome page, RAM usage climbs at around 1 MB every 10 seconds. Hitting the refresh button grabs another ~10 MB of ram every few clicks. The behavior is similar on all other web pages.

When I use the stable 6.0.2 startup is much quicker and only uses around 140 MB of RAM. Hitting the refresh button multiple times can temporarily increase RAM usage to around 155 MB but it seems to be freed periodically and never becomes unreasonable.

I'm running debian (sid) gnu/linux 64-bit.

Part of this is due to how ASAN works. Duplicate of #17925.
