Is there a way to create an exception and keep login-related cookies for specific sites when I clear "all" history/cookies/browsing data?

How do I view my synchronized devices from both Windows and Android?

Is there a URL syntax to go directly to a nested bookmark folder?
For instance, I want to go directly to "Watch List".
Bookmarks\Entertainment\CBS\Watch List

I have several websites that I visit on a regular basis. How do I retain only their information and delete the rest when I clear cache, cookies, history, etc. when I close the browser?

The problem is that after the data is cleared, many sites require re-authentication - sometimes a notable inconvenience.

Is there anything that can be done to Opera to enable it to play CBS All Access videos?

Occurs on multiple Opera versions - including the latest release.
Chrome, Firefox, and even Edge work fine. This has been a longstanding issue for all Opera users. Since other browsers work, it's safe to assume that the trouble is not with the site..

I don't use an Alt key much on any website but one. The Right Alt key functions as expected, but the Left Alt key seems to be disabled.
This only occurs in Opera - not Firefox, Chrome, or Edge.
Alt key assignment is not listed in Opera's keyboard settings, so how do I get the Left Alt key to function in Opera IAW keyboard standards?

The update a few days ago (?) screwed up my Speed Dial page:

• Several items were deleted
• Most of the custom Icons reverted back to ugly, unuseful generic icons
• All my groupings were lost
• All my Sorting was scrambled
• Previously deleted unwanted default sites were restored.

It seems apparent that the developers didn't take a user's Speed Dial page(s) integrity into account. Please don't ignore it next time???
