I refreshed the web page by left-clicking with the mouse on the refresh icon just to the right of the URL in the menu bar. Firefox still showed the bug as blocking. I then did a shift-left-click on the same icon (a full refresh). Firefox updated the web page properly. > > So, a full-refresh appears to be enough to work around the problem, at least for me (Firefox, Fedora 23 x86-64). Doesn't this indicate a bug in debbugs? Presumably when you did the simple refresh Firefox queried the server to know if a more up-to-date version of the page was available (using the X-Modified-Since header); it should have received a positive answer, but instead received a negative one (that would be the bug). Doing a hard refresh forces Firefox to bypass its cache; but ideally, debbugs should respond correctly to Firefox' queries and indicate that the page was in fact modified. Or am I misunderstanding something? Clément.
