then I believe it is a browser issue.
In Firefox 31, the items-per-page dropdown doesn't change the setting (even though the dropdown does change to the new value), and when there are page numbers, they are non-functional. It's a result of the new code, I suspect using JavaScript features that the older Firefox 31 doesn't support (haven't chased down those details and probably wont' bother)
Firefox 52 works fine (even though that page still sucks and is mostly useless)
Best recommendation is to try another browser.
(there are URL parameters that should affect the results and possibly allow manual page navigation, but they don't work in the older browser, and even though they do work in the newer browser, aren't needed because the feature isn't broken in the newer browser.)
Maybe they would work for you in whatever browser you are using. Worth a try.
To change number of items per page add &container_limit=100 to the end of the URL and load that URL (valid values are 25 , 100, and 200)
To change the page manually, add &container_offset=X to the URL where X = DesiredPageNum-1 * Items-per-page. (ie: For 100 items per page, to go to page 2 set X=100)
Last note: if you find a browser that does work, but don't like using it, you can just change the items per page to 200, and it will apply in the other browser and should stick (must be an account setting change that gets transmitted).
