Most of people (or at least which comes from Chrome and used the chrome's sync) wants that Opera does something like that, bu syncing theme and custom settings must be as basic as the bookmarks.
That needs to be implemented, and i don't say for me, but for most of Opera's users.
Where on the site?
That message means that some content on the page (such as an ad or image) is not secure, or that the security protocol used is too weak - though in this case we can exclude the latter as I would have seen a message on their landing page. Chrome would give the same warning.
When you realized you had closed the wrong window, you should have reopened it before closing the other window. If you have multiple windows open and close one by mistake, reopening it before actually leaving Opera is easy. Once Opera has been completely closed you can lose the tabs from your earlier-closed windows. At this point no real advice to help you, sorry.
So playing locally saved files (through the Windows media player AND through opera) does NOT cause lags. I can watch them without lagging. Right now playing YOUTUBE Videos works totally fine. I think Netflix is the problem. Netflix in Edge & Internet Explorer & Opera is causing laggs. Nothing else does.
So there is no Opera-specific problem, but one that affects all browsers equally in connection with Netflix.
Possibly, but this is only a speculation, these delays are due to Netflix checking the network traffic (periodically) for the possible use of VPNs . Since Netflix is not free, their customer service team should be interested in helping you with that issue.
The only driver I ever updated is BIOS and Graphics (today). Which drivers should I check aswell?
Especially with Windows 10 all drivers should be kept up to date, because the various operating system updates often entail far-reaching changes to which the drivers (for motherboard, sound card, printer, WLAN, Bluetooth devices, etc.) must be adapted. For security reasons, drivers that are up-to-date are also recommended.
This always seemed to happen with the Deviant Art speed dial but I think it had something to do with the server they used for graphics on their page now that I made a new dial it shows up consistently now. So if I were you I'd try making a new dial and see if that helps
The download directory in settings is for 2 things:
The path that Opera uses when it downloads a file type without asking. As in, it's for automatic downloads.
The path used for the default path the first time you use the Save As dialog.
The download directory in settings is NOT used for the Save As dialog. What Opera uses is the last path you used (or the download folder path setting the first time you use the Save As Dialog). Opera stores the last path used for the Save As dialog in the Preferences file in the profile folder. It's the default_directory string value under the root/savefile object in the Preferences file.
Now, what you're seeing is that in addition to "Save as PDF" using the Save As dialog, left-clicking on an EXE link for example will use the Save As dialog too (because Opera forces asking for that type even if asking is turned off for downloads in settings) and default to that last used path. Same thing if you right-click on a link and choose "save linked content as". But, if you were to download a zip file instead by left-clicking the link to it, it'd download automatically to the download folder listed in settings like you'd expect. Then, as you can guess, if you turn on asking for downloads in settings, even left-clicking on links to would normally trigger automatic downloads will trigger the Save As dialog instead, ignore the download directory path setting and default to the last Save As path.
It's kind of weird, but that's the case. There's no option that I know of to have the Save as dialog always default to a certain directory no matter what directory you saved to last time. Notepad++ has an option like this if anyone needs an example.
