Comment 8

[Olli Pettay [:smaug][[e-mail]]]

bug 1715300 was backed out.

Comment 9

[Olli Pettay [:smaug][[e-mail]]]

This seems to be an issue in the test.

Comment 10

[Olli Pettay [:smaug][[e-mail]]]

Attachment: Bug 1679194 - browser_backfwd_enabled_post_customize.js should wait until the state of back and forward buttons has changed, r=peterv

When session history (and bfcache) run in the parent process, things happening there are less asynchronous vs. having session history
in the child process.

The fix is such that if the disabled state doesn't change, then the test will just time out.
