I can confirm, that IMDB did some changes to their list page. The scrip overlay buttons not showing up anymore.
Lets hope AltoRetrato (Ric) will have some time to fix it. This script is still so much helpful to me :)
There were some changes in the last few days:
The "export link" for each list (which is used by my script) has been producing broken CSV files for a few years, causing the script to fail to refresh the data in some occasions (such as when a title have a special character). It seems this was finally fixed, but the file format have changed, requiring a script update.
The layout of Your Lists page was changed, requiring another update.
The "export link" for your watchlist is a bit "hidden" now, and the script have to download another page to be able to find your watchlist. BTW, if it seems that your watchlist is not being loaded, please make it public at least once: you can revert it to private right after that, but we need IMDb to give your watchlist an internal ID (and it might not do that by default for everyone, so that might require you to make the list public).
I just published v. 1.40 of the script, and tested on both Chrome and Firefox. To be on the safe side, clean you browser's cache after the upgrade then proceed to Your Lists and you should see the golden buttons.
Merry Xmas & holidays to all! And next year the script will celebrate its 10th anniversary, I'll let you know where we will celebrate! ;)

I also added an option to auto-update the script... I guess. I didn't test it and I really don't know how it really works, but we might find out in the next update.
Sometime in the last few weeks I stopped being able to refresh the highlight data for my IMDB lists: the progress bar instantly displays "Loading 1/4..." and stays there forever. All previous highlighting is cleared. I'm accumulating a great many titles in my lists, about 9,000 at the moment - is there any limit here? The IMDb also made some changes to its user interface for lists around the same time - if that were the problem, I'd imaging that no one would be able to refresh. I'm having the problem with both Chrome and Firefox (the version before 57.0), and having the problem on two computers. Thanks.
