v2.13.3

• Fixed bug #495: Markdown Here stopped working in Thunderbird version 60 (due to changes in Thunderbird).

  • Thanks to dugite-code for the PR to fix it. Also thanks to: Marc-Alexandre Espiaut, Tehmul Ghyara, Pedro Silva, PackElend, qolii, Francisco Pina-Martins, evazquez00.

• Fixed bug #435: On some pages, Markdown Here would spew cross-origin exceptions to the console. This was due to MDH trying to determine if a focused iframe-within-an-iframe was renderable.

  • Thanks to lincoln-b for reporting it.

• Fixed bug #427: In Chrome and Firefox (at least for some pages), after rendering the resulting text was selected.

  • Thanks to nedchu for reporting it.
