@nextsys Yes, I have a manual sync with two backup drives on another pi. So, I didn't lose my passwords, just a lot of annoyance that this happened when I tried out a new browser. Ive used FF for many years on many different machines and never had a problem so I will stay with them. Bye to Opera.

I think prudent thing to do for hassle free future is to use firefox

@nextsys Yes, I am quite sure the sync systems works because you send your data to another computer and then ask for it back later.

In my case, I prefer to keep my data on my machines. If I export a file from one provider I expect it to be importable by the same provider.

My file was produced by Opera and should be importable by the same software version. If importation software is change then the provider should warn when an export is attempted. If Opera has said, "Beware, you may not be able to import even in Opera" then what would I have done? Continued? The time between export and import was only minutes, not days even.

My problem I found related to the fact that I allowed Opera to enter my password which it had obtained from a Firefox import.

I deleted the password entry and entered what I knew was the correct (not knowing if the one entered before was correct.) That attempt to log in failed each time.

Eventually I removed the password and email from Opera and entered both manually. After some attempts and a reboot, it worked.

I am a bit disappointed with Opera because I exported the passwords to csv to edit them and deleted all from Opera. Now I cannot import what Opera exported!

I forgot to mention that I am using xubuntu not windows.

I have tried:

Enable opera://flags/#PasswordImport and then go to opera://settings/passwords and click on the three dots on the right o saved passwords.

Suggested by @leocg earlier this year.

I have a csv file of passwords which was exported from Opera on another machine and I want to import the.

I enable the import flag, click on the banana icon in passwords, select import, select the file and select open. The popup disappears and the passwords are not imported.

I am a member of UbuntuOne and have been using Firefox to log in there for some time. I have also used Chrome. Both have the same password and today I can use both to sign in.

However, when I try to log in using Opera with the same credentials I am faced with an error message saying effectively, "Bad Bot, Go Away". Not helpful so I consulted the Ubuntu forum using Firefox and was told that the problem was probably to do with the browser, Opera.

I have renamed the Opera cache file in the .config folder and restarted Opera, assuming that would clear the fault. It does not.

I could uninstall Opera and re-install it but I cannot find the bookmark of password file location.

What else can I do, other than go back to using Firefox?
