Dear Petter, dear list,

this bug was reported to firefox BTS years ago, and is still there.
https://bugzilla.mozilla.org/show_bug.cgi?id=235853#c260

With Firefox 11 or later (Windows WS), colleagues experience
regular timeouts. Well, I will try to use your alternative syntax,
and then, we have to discuss alternatives (or contribute a patch).

Kind regards
Ralf
