### Describe the Bug

Actually I'm using the outdated Android Kiwi Browser with floccus V5.8.0 and the sync works perfect.

Now I installed Waterfox, a fork of Firefox Browser, and installed floccus. This is the same android device, where the Kiwi Browser with working floccus is installed.

During the floccus setup in the Waterfox Browser I can enter my nextcloud url (by the way, this cannot be done in the plugin directly as a second tab window would be opened but you cannot access this second tab within the floccus addon therefore you have to start the floccus setup in a separate window) and after that you have to select the local folder where the bookmarks should be stored.

But this is the problem, I cannot select any folder:

And therefore I cannot finish the setup and the sync won't work. I tried everything I know to solve this issue by creating any other default folder within the bookmark settings in the Waterfox Browser, but still, no folder can be selected.

### Expected Behavior

Same as on every other floccus installation, during the setup, the default local bookmark folder should be clickable.

### To Reproduce

Install floccus on android Waterfox Browser and try to complete the setup.
