Description

List creation window hangs when uBlock Origin's Cosmetic Filtering is enabled on Firefox

Normally, when you create a list, you click the little down arrow next to the Star button:

It'll then show a dropdown where you can select from your previously created lists or create a new list. Selecting create a new list, then making a title and description for the new list (the content of those fields doesn't matter, I tried it 5 different times, and it only worked with Cosmetic Filtering disabled.) Normal behavior is for the box to immediately close after you click the Create button:

However, if you have Cosmetic Filtering enabled, as is default behavior, it hangs, and just stays like this indefinitely, until you refresh the page. It does create the list immediately, adding the repo to the list, but the create list box never closes.

Disabling Cosmetic Filtering fixes the issue. I do not know if there is a more granular approach.

Other extensions used

• Bitwarden
• Sponsorblock
• Return YouTube Dislike
• TamperMonkey
• Firefox Multi-Account Containers

None except Bitwarden are active on GitHub.

It's strange that I don't see any filters in your config log.

The issue occurs to me even when I turn off uBO completely in browser's extension settings

It would be useful to test how it works on Chrome, then it is worth giving a label specific to Firefox
