I can confirm, I just upgraded to latest (1.3.115) on Ubuntu 18.04.4, and it started the random freezing again.
I’ve downgraded again to 1.0.1, but I am probably going to pull Firefox or Chromium out until this is patched, so I can keep a patched browser.
If there are any logs or other data that I can provide in order to assist, please let me know.
