Eek! It seems to be working fine for me in v1.6.0->1.6.3. What symptoms are you seeing? Is it that you can't add new tags, can't get your BM list trimmed down or something else?
Can you also try pressing CTRL+SHIFT+J? If you do that you that, click clear and the refresh your E page you should see a line like "Starting Elliquiy Improver v1.16.3". And then potentially some error messages. Those messages might point me in the right direction...
The issue I was having was that whenever I would click on one of my BM tags it was showing the full list, not just the ones tagged with that tag. I did specifically check to make sure there were things in the tag, and that there were things not in the tag, and both ways the list never changed.
Now as of this morning and updating to 1.7.x the script seems to be effectively disabled for me. Grease Monkey is running and enabled, and it says 1.7.x Elliquiy improver is installed and running on the page I'm on. Give me a bit for more debug info from ctrl shft j
Update: Debugging info says basically what I assumed. It never displays any message similar to Starting E.I. at all. Simply a warning about getElementById() is null from the Shoutbox thread, and an NS_ERROR_FILE_NOT_FOUND error, as well as SHA-1 encryption not being recommended because well... Yea.
Update 2: After letting the page settle for a bit, this showed up: https://talkgadget.google.com/u/0/talkgadget/_/frame?v=1436379713&hl=en#egtn_tdiusy
