In 2020, Mozilla introduced Collections on the new Firefox for Android (Fenix) as part of the multiple changes to its Browser on Google's OS. It was (and still is) a good idea, but there hasn't been any development on this feature since then, which is a shame since there is a lot that can be done to truly make Collections useful, practical and easy to use, so that it may become on of the staple features highlighting Firefox for Android from other android browsers.
What should be done:
1.1 Allow the choice of the Collection's colour (from those already supported) upon its creation, at the same time as its naming.
1.2 Furthermore, instead of the "Rename Collection" option upon pressing the "3-dots" button, we should have "Edit Collection" so that we may also change later on the Colour of the Collection.
2.1 In the "Customize Homepage" Setting, Allow to Switch On/Off and choose one mode of Automatically Sorting Collections:
- Newest to Oldest
- Oldest to Newest
2.2 Allow Long-press, then Drag-and-Drop to manually Sort Collections (when Automatic Sorting is disabled as proposed in 2.1), both on the Homepage and the "Customize Homepage" setting
3.1 Expanding on the "Edit Collection" option in 1.2 , allow a Switch to Automatically Sort Tabs, again Alphabetically, Newest to Oldest or Oldest to Newest.
3.2 There should also be an option to enable manual sorting in "Edit Collection" by Long-press + Drag-and-Drop within that Setting.
4. Allow to Long-press and select multiple Tabs in a Collection (with possible actions being Bookmark, Delete or Open in Private Tabs).
Alternatives to 2.2 and 3.2 (while also being a possible action for 4. ) :
I think that working on all these ideas concurrently would be simpler (since there is some integration with one another) and well-received by everyone as a major and refreshing feature update.
