@gmiazga This is what my browser shows me:
"Jouw versie is 63.0.3368.94
Dit is de meest recente versie van Opera
Laatste maal gecontroleerd op woensdag 2 oktober 2019 08:05"
Meaning 63 is the latest version 3 minutes ago. No version 65...

@leocg Good to know, thank you

@leocg Sorry, but that is not possible. The bookmark bar pops up before you select a place to store it

@popinjay01 How long did it take? I have got hundreds of bookmarks in kind of 50 categories. I cannot imagine this is what the developers had in mind, it seems like a tremendous waste of time, while there should be a button that ensures one simply does not use the bookmarks bar and it should never pop up. Something that was default state in earlier Opera versions.

@holecrap Different people, different opinions, what can I say? I neither use the bookmarks bar, which I find annoying, nor speeddial, one of the most needless features that Opera came up with and all other browsers copied, I have no clue why. Oh, I see, there are people who like it like you. Could you explain why?

@sgunhouse : ... and how can we stop it?

@nvmjustagirl That's what I'm doing again and again

In my case it's different. 5 minutes ago I received an email with a link (using Thunderbird), which I clicked and the next thing I saw was the bookmarks bar in my browser.

Hi,
Yeah, I know, some of you must like the bookmarks bar, there must be a reason why Opera introduced it. Anyway I have never used it and am not planning to do so, however my browser seems to want me to. Since a little while Opera opens the bookmarks bar whenever it likes. Have not yet found the pattern. Opening a PDF was my first suspect, but it only pops up every second time, not always. Also when I click on a link in an email, or I open a new tab: bam, here it is again. I switch it off, but I never have to wait long before it returns. First I regularly switched it off but meanwhile it tends to become a little annoying. So this is my question: how can I get rid of it forever? Any ideas? Thank you !
