 Replying to [ticket:24934 cypherpunks]:
 > 1. Open Tor Browser and GNOME System Monitor.
 > 2. Go to https://pomf.space/
 > 3. Open the Inspector `Ctrl+Shift+C`
 > 4. On my system the CPU usage hits up 99%, and after some time (+30min)
 memory usage of firefox reaches 700Mb and of Web Content reaches 700Mb as
 well.
 >
 > Could this be a memory leak?
 See if it is fixed in a new version of Firefox esr by running the command
 below.
