IE >= 10 Login spinner takes forever

[renoirb]

We are having an issue with our version of FxA and we are wondering if you experienced a similar issue and if it has been fixed since then. We forked FxA on May 21.

Reproduce

Under Internet Explorer 10+, on a OAuth signin flow. When the user clicks signin, the "spinner" goes for a long time.

Sometimes it resumes and gets back to the callback. But most of the time it hangs for a long time. In some cases, we can even "wake it up" by clicking somewhere random (e.g. the white background) in the FxA view.

The behavior can be seen here at precisely 2:34.

PS: I didn’t, yet, try with the current FxA version. I’m working on it.

An update

I just made some tests under IE11 and it seems we do not experience the issue with the current version available on stomlinson.dev.lcip.org. Which is great!

I guess is that migrating our customizations on the latest version would liberate us from that issue.

Was able to login! Seems like it is working on our end.
