Forum Response - Firefox for Android Bookmark Management
Thank you for your question about better bookmark management in Firefox for Android.
Bookmark management is still being developed, but a delivery date is currently unknown. If you want an early look at this feature, you should install the experimental Nightly edition of Firefox for Android from Google Play.
Nightly is a pre-release version of Firefox, therefore it may contain some unresolved issues, but it will allow you to try the bookmark management feature in Firefox for Android. Once installed, long press on a bookmark to be given the option to Edit the bookmark, where you can change the folder or create a new folder for the bookmark to be stored in.
Please follow the Mozilla Blog for updates on this and other new Firefox features.
