Body

Seems related to other issues some people are having (see https://github.com/orgs/community/discussions/64121#discussion-5531690)

I've included screenshot of the logs produced a moment ago when trying to add a list in Brave Browser. I decided to look into the Greaselion as I had never seen this before. Using Chat GPT-4 provided me with the following info:

... in the context of the Brave browser, "Greaselion" is a feature that enables developers to add custom scripts to specific web pages, akin to the idea of userscripts in Greasemonkey/Tampermonkey. This can be used to modify web pages on the fly, provide additional functionality, fix bugs, etc.
The GreaselianError you're seeing in your console would likely be associated with an issue or bug with these custom scripts.

After seeing that, I quickly swapped out Brave for the Firefox Dev Browser and found that this bug no longer occurred. Additionally, the lists that I created in Brave did show up (in other words, they were in fact created), so the bug is not that lists aren't created. It's that once a new list is created, the browser window hangs.

This discussion duplicates #50880, just as a dozen of other reports.

I want to add that I have the same issue with Safari 17.1 on Sonoma, M1.

List creation fails only client-side. Reloading the page shows that the list has indeed been created and the repo correctly signed to it.
