FF 60.0.1 – MacOS 10.13.4 When creating a new bookmark of the current page by either Cmd+D or clicking the star icon in the far right of the location bar, a box with the title "Page Bookmarked" appears. [Nb. The titles change if you are editing a bookmark that was already saved.] This box contains: - A text field to edit the name. - A (mostly useless) combo-box of hard coded top-level folders, followed by "Choose...", then an abbreviated (and inaccurate) list of recently selected folders. - A disclosure arrow that expands the box to show a scrolling tree table of all your bookmark folders. (also achieved via the "Choose..." option from the above combo box. - A text edit field to edit (non-tokenized) tags. - A disclosure arrow that expands the box to show a (non-editable) multi choice table of existing tags. - A "Remove Bookmark" button. - A "Done" button. The disclosure state (whether it is opened or closed) of the Folder or Tags tables is never saved. i.e. Every time I want to bookmark the current page I must grab the mouse and go click on the Folder disclosure arrow to choose the folder I actually want. Yes, I must actually use the mouse to save a bookmark where I want it _every_ _time_. While the bookmark folder tree table is perfectly navigable via the keyboard, i've been unable to find a way to make it disclose without clicking. I had a go at tweaking via a userChrome.css but was unsuccessful. I'm able to expand #editBMPanel_folderTree size (an _extremely_ necessary tweak IMHO, why is it so small by default?) but not make it show on launch. I've replicated this behavior on a completely clean instance of FF 60.0.1 with no extensions or modifications. Perhaps i'm missing something? Is this just a bug? Hard to believe this is intended behavior. Thank you in advance for any assistance, this is driving me bonkers. =D [edited for formatting]
