Comment 17 for bug 1616650

@echaskaris, fortunately with Chromium (maybe Chrome too?) there is a way to recover your session that vanished after the unexpected refresh. You need to revert to the previous snap (sudo snap revert chromium), start a Chromium, go to the "hamburger" menu, "More tools" then "Task manager". There, you can double click on one of your tabs to bring back the old window/session.
