Twitter.com tabs in the latest version of Brave crash (page freezes, and eventually browser pops up a notification stating that the page is frozen and a choice to "wait, or “kill”) for me immediately, when the “emoji menu” is opened while authoring a new tweet. This happens both with shields, up and with shields down.
This is on Ubuntu 18.04.1 LTS AMD-64 (Openbox Window Manager).
If anyone else has experienced this, or similar, please don’t hesitate to let me know. Also, of course, if anyone has found a solution or workaround for this, that’d be great as well.
