Firefox URL mangled when using browser sync

[verrol]

This doesn't happen if you use Firefox or Chrome alone. But if both Firefox and Chrome are oped at the same time. The Firefox URL will get manged after creating a record in a Jhipster app. I opened issue jhipster/generator-jhipster#1483 on JHipster, but they said it is a BrowserSync issue.

How to reproduce:

1. Created a new jHipster app
2. Added an entity
3. Use Firefox to add a record
4. Open Chrome, log in using the same account.
5. Firefox URL now looks like GET request with all the entity fields as request params.
