@leocg If another user starts my computer to see something it would very probably be in my email client, not in my browser.
It's not the perfect solution, but it's the best so far I suppose.

@leocg Anyone can turn the computer one (for instance if you're ill or away) so this won't be very appreciated by the colleagues I guess
But I'm thinking of putting a password on the hole Opera browser with that Opera Lock add-on, and if somebody needs to find something out on the internet just use one of the other browsers that are on the computer.

@zalex108 Hello
Thanks for your reply, but "Set password for your browser ( Opera lock )" add-on puts a password on Opera itself ? You can't specify for a specific website for instance ?

Hello,
Is it possible to add a password protection on specify websites ?
Let me explain: I have add the web.whatsapp website to my Speed-dial buttons on the computer at my job, but only I should be visiting this website (because it's the whatsapp of my personal phone). Anyone can switch my computer on, the computer is not protected by any password.
Or if there is another / better alternative for my problem I would be glad to hear that too.

Hello,

It seems like I used the 'double click in title bar' a lot to open a new tab in the previous Opera versions, but since the update isn't possible anymore (it just rescale the opera window, like most windows applications)
Can this be fixed ? With a plug-in maybe or anything else ? Can't seems to find anything in the options.

I have to agree for the thumbs on the speed-dial, it's totally not clear on which one you have to click, it was better previously when it was a miniature of this website.
