Thank you, lando242, I hadn't thought of that, but it's does the same thing with uBlock turned off .
I forgot to mention: with other browsers it just logs me in without going to my profile page. And stays logged in.
Go to the Opera menu, navigate to bookmarks and right click the folder you wish to order alphabetically. You will see 'Sort alphabetically' in the right click menu. This must be don't in the Opera menu and not the bookmarks manager, as the bookmarks manager does not currently support it.
Why on earth are you replying to a thread last posted to a year ago, quoting a post from eighteen months ago?!
A spam post (already deleted) has bumped the thread and he probably didn't notice the date.
It's better to have that thread closed as its relevance today is dubious... If anyone still has anything new to add to the subject, any complaints, suggestions, etc, you're very welcome to join other threads or create a new one when appropriate.
