In mobile go to Settings -> About Firefox and tap the logo several times until it says that debug menu is now enabled. Go back and select Nimbus Experiments. Look for "Mobile Bookmarks Improvements xxxxxx" (may be more than one) and uncheck any active experiment. Restart Firefox and problem should be fixed... for now.
Brandoaz's suggestion worked. I unchecked the "Mobile Bookmarks Improvements Release" and it went back to the previous (correct, in my opinion) behavior. I can access my Desktop bookmarks and they're in the same order as when I use the desktop browser.
I'm not sure why the current state of bookmarks is considered an improvement. It's like going backwards 15 years. I'm not looking to bash the developers. I just want to stress that users do not want to remove basic functionality. This is out-of-character for Firefox, in my experience.
Feels like there's a weird disconnect between what the original suggestion is asking for and the suggestion made a few months later.
People are throwing around the word "random" and "organized" but meaning something completely different, too. To some people, "organization" is a matter of choosing between automatic sorting types. To others, "organization" means manually ordering.
Some people wanted things sorted automatically and asked for it, in place of the original way, which was to simply mirror the manually-set desktop ordering. So the devs gave them that, ignoring that plenty of other people wanted their desktop ordering to be left alone. And now we've got another request asking for that functionality to be returned, from different users, who weren't asked what they wanted when the experiment was started.
This could have been easily avoided by simply designing this, from the start, as a *visible option* the user can choose and not a unilateral change.
I don't know what you mean by "desktop ordering". I just want all of the bookmarks under the Bookmarks menu to be alphabetized, at all times, plain and simple. I'm using Firefox on Windows, not on a phone.
The ability to sort bookmarks as per the user's needs should be a core functionality of any browser with bookmarks, in my opinion. Sorting must be possible on the device on which the browser is running. Desktop and mobile browser may be used for different purpose and in different situations. So the bookmarks differ. At least that is the case for me (and many other users, I assume). Therefore, manual bookmark sorting (including sorting of folders) should be enabled in Firefox for Android. Referring to the sync option is not sufficient. Not every user wishes to sync their bookmarks.
