I prefer Opera over other browsers for the following reasons:
-seems lighter on resources and a bit more responsive/quick than even Chrome, Firefox, and Vivaldi
-best tab preview of any browser - I can check on the tab/page's content simply by hovering over the tab
-full-screen is truly full-screen and allows me access to both open tabs and closed tabs very nicely via Ctrl-M; I can also access Facebook Messenger easily while in full-screen mode by Ctrl-Shift-M.
-keyboard shortcuts for extensions work in full-screen mode perfectly (unlike Vivaldi); Firefox has no keyboard shortcuts for extensions
-does not tap-out my laptop battery as quickly as other browsers
-Instant Search (Alt-Space) works terrifically and is a great way to access bookmarks even in full-screen mode
-customizable keyboard shortcuts (not quite as good as Vivaldi in this respect, but still very good)
-built-in snapshot (Ctrl-Shift-5) is very nice
-speed dial is better and snappier than other browsers
-Personal News integration with AI news/categories is innovative and creative and intriguing
-Facebook Messenger in the pinned sidebar is very nice; I like it better than Vivaldi's implementation. Other browsers simply don't have it. (request: Twitter in this sidebar would be heavenly!)
-address bar input seems to predict what I am looking for better than other browsers
-it is more appealing to the eyes than other browsers. I like the bright wallpapers in Light mode very much.
-MyFlow with Opera Touch on phone is excellent
-neat little features other browsers do not have like tap on tab to take you to top of page/tap again to take you back to where you were on the page
-neat little features like mouse gestures that work and don't overwhelm with too many choices
-the best tab management of any browser I've found to be able to simply go back and forth between two tabs quickly and easily. I use Ctrl-tab for this.
-built-in ad-blocking capability (I assume this is more resource efficient than relying on extensions for this)
-neat little features other browsers do not have like the ability to close a tab with Alt-mouseclick
-neat little features other browsers do not have like the ability to select multiple tabs and then right-click them to copy all their page addresses (URL's)
-neat little features like the ability to select multiple tabs and then right-click them to save them all to a Speed Dial folder

I agree ... let's get it done! Thank you in advance!

One more advantage I see with Opera over some other browsers is the very nice layout for extensions:
-Enabled
-Disabled
-Updates
-Under Development

It has helped me locate one or more extensions in the past more quickly than I would have located them without such a nice breakdown.

The lack of transparency or forthrightness about this is rather stunning. I would think Opera would have someone dedicated to responding to these things or other issues/complaints in a direct manner if public relations and retaining users means something. Opera could hire me if they wanted to for these sorts of things. I like the browser on Windows very much, and would be willing to help Opera and its users come to a meeting point where confusion or disappointment could be alleviated or explained in an honest and understanding manner.

I really like Opera on the desktop. It's my preferred browser. I have an iPhone and would really like to try out this new mobile browser that is only available on Android at the moment.

From what I read here and elsewhere, OperaMini is a total failure from insufferable/inappropriate images and unwanted and non-customizable newsfeeds.

I want to be an Opera-fan on mobile, too.

Any updates or news about its availability will be appreciated. Thank you in advance.

@temkem Oh, yes! You are right, temkem.

Thank you ... @johnd78 !

It doesn't work in a private window for me, either. As for "codecs," I'm not sure what that means, but as I said, numerous other browsers are playing this video with my existing "codecs."
I simply get the message at the bottom of the video screen which says, "The video could not be loaded, either because the server or network failed or because the format is not supported."

Thank you for your reply.

@coffeelover Thank you. If Opera would like to employ me doing that sort of thing, they can contact me anytime! I prefer to work from home, though.

While I am here, let me add another reason why I prefer Opera over other browsers:

Opera has built-in Cryptocurrency Mining Protection and Malware Blocking

Other browsers force one to research/search for such protection via extensions. I know Opera has got me covered for this already, so it is one less headache/concern for me. I have enough headaches/concerns, already.

@temkem Thank you! I had to do the same for History Panel. Actually, Bookmarks Panel worked as advertised upon a restart of Opera without having to adjust that flag.

A little flaky, I guess ...

The only video that does NOT play for me is the tiny video labeled H.264/MP4

It means that Opera isn't being able to play h264 videos on your computer for some reason.

Yes, and that makes Opera a less viable option for me, as other browsers have no problems with such videos. If anybody knows how to make Opera play such videos on a Windows 7, 32-bit system, I'm all ears.

Thank you!

Keep up the good work with the browsers, Opera!

I use Opera on desktop and Opera Touch on mobile. I have tried Brave (on both desktop and mobile), Vivaldi (on desktop only), Chrome (on both desktop and mobile), Safari (on mobile only), Firefox (on both desktop and mobile) and Palemoon (on desktop only) browsers, and I still find Opera to be my favorite most days on both desktop and mobile!

Opera updated for me today (12-13-19) to Version:65.0.3467.72 ... I don't know what changed.

@leocg Yes.

While in FullScreen mode, Ctrl-Shift-M does not cause the sidebar to appear. When Ctrl-Shift-M is used in FullScreen mode, the sidebar does not appear UNTIL FullScreen mode is exited.

Version:65.0.3467.54

Windows 7, 32-bit

It seems we have a secret update for Version:65.0.3467.54 with ads on the Speed Dial page. Interesting!

Nice! Thank you!

What is today's update bringing us? In other words, what is the changelog for Version:65.0.3467.48? Thank you.

Opera Touch is terrific!

Little blue dot for personal news updates no longer appears next to the personal news icon in the sidebar when updates are available in Version:65.0.3467.42 here.
