If the sidebar is there, right-click in it and you should get a menu listing the possible panels to show in it. Just select all the ones you want, leave the others hidden.

Note that 65 is the current stable version, so I don't think anyone will care about posts to this thread...

Sure ... but it would be nice to have it clean itself periodically. Maybe on restart, and perhaps it should ask before getting rid of them. But we do see a number of issues related to Sync duplicating deleted bookmarks in their original location since the Trash hasn't been emptied. Something has to be done.

Same way anyone with two devices merges their speed dials - go to the Bookmarks manager and Copy entries from Other speed dials then Paste them into that machine's Speed dial folder.

If @opera39x wants to see saved passwords, then this is not the right topic.

I've had more than that before.

Did you set for Opera to "Throw away new cookies on exit"? If not, then some firewall or cleaner could be the cause. (Some firewalls can change cookies to session cookies, same as the setting above does, so they get removed when the browser is reset. Ccleaner and some similar programs can clean the cache and cookies when you reboot the computer.) Check the settings in whichever you have.

Most likely some form of adware. Check to see if the shortcut (desktop, menu, whatever) you use to start Opera was modified to add the website to the command line; also if you recently installed any add-ons try disabling them and see if that might be the cause. Otherwise ... did you install any new software about the time this started? Maybe Ad Aware or a similar anti-adware program would find it.

Don't know if anyone actually watches the bot account ...
