Tor Browser crashes when IPC connection got lost
Sometimes something happens during load of a new page in a tab, and then other tabs show loading circles instead of pages, and nothing happens, except increase of
1,696 (100.0%) -- queued-ipc-messages
└──1,696 (100.0%) ── content-parent(???, pid=3796, open channel, 0x133abab8, refcnt=46)
which leads to OOM of the main process. (Killing child process brings TBB back to mind.)
