Back button on Firefox 52 hangs with "Loading..."

[Jiang]

Openstack Ocata. First select a label, such as Project/Compute/Instances. Then select another label, such as Project/Compute/Images. Finally, go to the previous page by click the button of Firefox(the back button of firefox on the top left), the page will always show Loading.

[Akihiro Motoki (amotoki)]

In my understanding, this is the expected behavior. There is less value to show old contents because the actual information may changes since then. I would like to hear opinions from others.

[David Lyle (david-lyle)]

Horizon caches very little data, none across requests. So loading every page must be loaded when requested. The only exceptions are in the fully angularized views like images where going between the details view and the main view will not require a full page reload.

[David Lyle (david-lyle)]

Unless you mean that the loading symbol never goes away, then we could potentially have an issue. Could you please clarify?

[Jiang (jiangpf)]

Yes, I can see the contents of the page after click the back button, but the loading symbol never goes away, I can not do anything, unless the page is refreshed manually.
I do these on chrome, there is no such problem. I only found the problem on Firefox.

[Gary W. Smith (gary-w-smith)]

I see this, too.

[Kyrylo Romanenko (kromanenko)]

I can see this bug with Firefox 53.0.3 (64-bit)

    Fix back button on Firefox and Safari

    Firefox (and Safari) uses bfcache (back-forward cache)
    to load re-visited pages. The solution is to force a reload
    when page is loaded from bfcache, so back button will work
    correctly.
