By the way, how to make the alert and confirm window vertical in vertical writing mode ?

For convenience of developers looking into this, could you attach a simple testcase? Thanks.

Is multiprocess (e10s) enabled when you're testing this? (Check for "multiprocess windows" in about:support.) This looks like it may be related to bug 1170129, which describes similar problems for <select> when e10s is active.

According to the about:support( autocomplete2.png), the Multi-process staged rollout = true.
But I do not know how to set to false.

Try going to about:config and setting browser.tabs.remote.autostart and browser.tabs.remote.autostart.2 to 'false' (if they're both present, I'm not sure exactly which setting is in which Firefox version...), and then restart Firefox; I think that may alter the behavior.

I set both browser.tabs.remote.autostart and browser.tabs.remote.autostart.2 to 'false' on Firefox 50.1.0.
But no luck.

Yes, you're right, this isn't fixed for any configuration. Turns out we do already have a bug on file, actually; I was mis-remembering which issues were still open.

Bug 1153311 talks specifically about use of <datalist>, but the autocomplete popup will be the same whether it's driven by an explicit <datalist> in the page, or suggestions stored from previous submissions. So I'm dup'ing this to the existing bug.

OK. Is there any discussion about alert and confirm popup window in vertical writing mode ?

Not that I am aware of. Could you file a separate bug describing that, preferably with a minimal testcase to illustrate the issues? Thanks!

I filed a bug about alert and confirm at https://bugzilla.mozilla.org/show_bug.cgi?id=1324963.
