For the last few weeks, clicking on the title of a submission in the firehose list of submissions sometimes (for me, several times a day), rather than expanding the view so that the submissions text as well as its title is visible, instead triggers display of a FAQ entry about JavaScript (https://slashdot.org/faq/UI.shtml#ui700).
Not sure how to better describe how to reproduce this behavior, but I know it's been seen by a few of the authors.
Just hit this again, just after clicking on the triangle to expand the field in which to enter tags and admin commands (hold / games / etc) when looking at the expanded version of a story within the hose.
