Light firefox re-directs me to forum index after replying to a thread

[Anonymous Anonymous]

Using light FF 47 and on a certain forum, when i reply to a thread and then refresh the page, i get re-directed to the forum index of the post that i just made. This only happens on light firefox and the problem is now present on firefox 47.01.

This is the forum : https://forums.e-hentai.org/index.php?

After replying to any thread, if i hit refresh, i get re-directed to the forum index instead : https://forums.e-hentai.org/index.php?

Error console shows a bunch of warnings, mostly "unsafe cpow usage", whatever that is....some interesting ones though :
