We always had the problem again, when trying to phpMyAdmin to work with the Firefox problems occurred. This expressed so, that no search results were displayed, the tables were empty, it was not on the next page, etc..
Most here helped launch the Firefox or delete the cache completely. But if we have in other pages or tabs, which should not be closed, was very angry.
A tip for this purpose: The “Start Private Browsing Mode”. All other tabs will receive and you can quickly make changes to the database and then exit back to the private browsing mode. So one must not restart Firefox.
Maybe it helps one or the other.
