oh, I faced the same issue. I install Opera on another laptop, turn on synchronize, and then all my passwords get lost (on my laptop, PC, and phone), I went to https://www.sync.opera.com/ but all passwords were gone as well. Does anyone know how to recover lost passwords

I just got my Opera upgraded to the the latest version (45.0.2552.635), with new features, performance improve ... But the "View in Bookmark" was replaced by the "Done" button. The "View in Bookmark" is the most useful feature for me, cause I often put all the relate urls into the same folder (like : House tips, working, books ...), so I can find them all just by remember the folder name or at least one of the urls, then "View in bookmark" button will help me to browse to the folder.
Hope this feature will comeback someday.

Thank @zalex108, It worked. I also go around with the Portable version of Opera, and I see they've done the same : edit the installer_prefs.json , change the single_profile field to true. Thanks again for your answer.

With Firefox, and can create new User and custom the Profile folder with cmd firefox.exe -p, create a MasterPassword for each account (in cases there're more than one people using that PC), hope Opera will have that feature someday

Hi, I've already posted a discussion about how to change Opera's profile and cache folder (by create and custom a shortcut to launcher.exe file).

It worked, but when I opened a link (from notepad, Pdf, docx ..v.v..), It'll open new Opera window with the default settings (Profile and Cache folder in C:\ ), and because It not use my custom Profile folder, the new Opera Window won't have all my settings (bookmarks, extensions ....)

So, I think It'll better if we have a option in Setting, to change the default Profile and Cache directory.

Thanks @leocg, It worked for me !!!
For those who got the same question like me, create a shortcut to the "launcher.exe" in Opera installed folder, rightclick on it and select Property, at "Target", add those command :

1. --user-data-dir=<YourCustomDirectory> -> change the Profile folder

2. --disk-cache-dir=<YourCustomDirectory> -> change the Cache folder

Done.

Hi, I'm using Opera v43.0 on Window10 x64, we all know the directory of Profile and Cache folder in :
-Profile: C:\Users<UserName>\AppData\Roaming\Opera Software\Opera Stable
-Cache: C:\Users<UserName>\AppData\Local\Opera Software\Opera Stable
Can we change it to another folder in or E: ..v.v.. ?
