I highly suggest that you consider adding a feature to add icons to the folders natively on your software And I highly suggest you follow the path of an extension called STG, Simple Tab Group Where they added a way to add icons for the containers But what I'm asking is to add a feature to add icons to the folders of the bookmarks section across the whole Firefox software, and you need to add a way for the folders to add icons in the PNG extension for better usability and compatibility because anyone could make an icon out of a (.PNG) and this is an easier path for icon recognition or creation I have more than 600 folders (that's including folders and subfolders) and I tried to add icons to them to identify them easier I came up with a solution, but it's not that good my solution is to add emojis to their names in the front of them or in the end of the folder names to easily identify them by looking because if you have more than 30 folders searching for them would be hard, and it's also more aesthetically pleasing and easier on the eye.
