User Profiles Transfer to Portable Cent

[producer]

Hi,
I still use the portable version of Cent - Version 2.4.2.19 (64-bit) (portable) (Chromium 56.0.2924.87).

I want to download the last portable version, v3.0.4.27 [2017-11-10].
Once downloaded, how can I transfer all my profiles, passwords, bookmarks, settings, etc. (i.e. EVERYTHING) from the older portable version to the latest portable version?
Thank you in advance!

Please backup your current User Data directory firstly.
Then you can extract 3.0.4.27 and copy previous User Data there.
As your version is too old, we can't ensure you all profile data can be kept.
But most should be kept well.

Well, everything done successfully, thank you!
BUT:
Since I updated to the latest portable version, I started experiencing a weird annoying problem!
It's about using a custom template on eBay. When I copy all the html and paste it to a newly created listing, all the frames, icons, columns etc. are ok. But when I start typing a text and title for description, whatever I do, the page jumps by itself to up. If I even type a letter, space, backspace, deleting, etc. - the same annoying effect!
I run the older version of Cent (mentioned in the first topic) and no any issues appear like in this newest version.
So the reason is definitely in the latest Cent version, not in me.
So please, anyone help me to solve this issue.
Big thanks in advance!
