defaults write com.operasoftware.Opera OPDisableAutoUpdate true

This should be what you're looking for :). If it worked, Opera will tell you "Update checker is disabled" when you go to Opera -> About Opera.

@mrmatteastwood Install http://launchpadlibrarian.net/345863538/chromium-codecs-ffmpeg-extra_62.0.3202.94-0ubuntu0.16.04.1317_amd64.deb (you can upgrade it again to the most recent version once Opera 51 stable has been released).

The problem is that Chromium was updated to 64, and the chromium-codecs-ffmpeg-extra package that comes with Chromium 64 only works with Opera >=51.

The other way around as well: Opera 51 will only work with chromium-codecs-ffmpeg-extra >=64, so once Opera 51 has been released and you've updated, you'll have to upgrade this package again.

@aleksod correct, that article is wrong (on more than one point). It looks like the journalist didn't actually use Opera before writing the article

@fjuk We don't 'choose' to limit this functionality. Unfortunately there are complicated legal restrictions around distributing support for H264 video decoding, and it comes down to 'we can't give you this functionality ourselves'.

Therefore we rely on others to give it to you. On Windows and Mac, it's the operating system that provides libraries that do H264 decoding, and Opera uses those. On Linux it's a bit more complicated, but it comes down to 'we use what Chromium uses except we can't give it to you ourselves'.

Unfortunately this means that now and then, when the library Chromium uses changes, Opera needs a certain minimum version of the library to be able to work with it. The rule of thumb is that Opera can always use a library if it's the same version as the Chromium version Opera is based on (check opera://about to see which Chromium it's based on), and sometimes older versions, depending on when Chromium last changed the library. Since the library changed in Chromium 67 / Opera 54, we currently can't use older ones.

While we are waiting for the stable package to be updated in Ubuntu's repositories, if you want a more official, Ubuntu-supplied up-to-date version of the codecs package, there's a package available for Cosmic Beaver which is already at Chromium 67. You can find it here: https://packages.ubuntu.com/cosmic/chromium-codecs-ffmpeg-extra .

We're aware of the issue and it'll be fixed in the next update to Opera.

For people struggling with automatic update, it's much easier to disable it like this (and easy to revert later too):

Open Terminal.app and write

defaults write com.operasoftware.Opera OPDisableAutoUpdate true

@andrew84: This is how it is very much designed to work - similar to the app switcher you have in your OS (Alt+Tab on Windows, Cmd+Tab on Mac) and also similar to how this feature already worked with a different UI in Opera before.

If you prefer to cycle tabs in visual order, you can do this - as before - by disabling the option "Cycle tabs in most recently used order" in settings.

@jimunderscorep Opera 51 has now been installed, so a choice is no longer needed

Everyone: update to Opera 51 and you can now use Chromium 64-based ffmpeg codecs.

You can also set the environment variable OPERA_AUTOUPDATE_DISABLED. This works on all platforms.

For Opera 32 and newer, you can use a global Apple preference. From Terminal, enter one of these commands:

For stable:
defaults write com.operasoftware.Opera OPDisableAutoUpdate true

For beta:
defaults write com.operasoftware.OperaNext OPDisableAutoUpdate true

For developer:
defaults write com.operasoftware.OperaDeveloper OPDisableAutoUpdate true

Seems to be because the site has multiple frames that are independently scrollable (top header, news categories on the left, news articles on the right). Scroll-to-top only scrolls the main frame to the top, which is not scrollable in this case so nothing happens.

I'm not sure if Opera should try scrolling up all frames on the site or we should just accept that it doesn't really make sense on multiple-frame sites.

@andrew84: Looks like the section is not disappearing when 'My Flow' is disabled, I've reported bug DNA-85967.

@burnout426 This is correct, we could see from our statistics that the number of users actually using Instant Search was negligible, even despite its prominent place in the Sidebar and various attempts to hint users at its existence.

However, we got a lot of positive comments about the 'Search in Tabs' associated feature which was until now a more hidden part of Instant Search.

That's why we have - with some regret - removed Instant Search, but kept (and made more prominent) the search-in-tabs feature.

@pilgi3 I'm sorry, sometimes hard decisions need to be taken. I hope you'll still enjoy Opera's other features. And I'm also hoping that maybe an extension developer feels like reviving a floating search bar as an extension

@firuz-u7: Under the O-button and then 'History', you can find the 10 most recently closed tabs and windows. The functionality should be the same as you had in the tab menu before. Let us know if you're missing anything.

On Mac, this can be found under the 'History' top-level menu.

Is it zoomed in, maybe because of trackpad usage? Try pressing Cmd+0 to go back to 'Actual size'.

@keen-operatic It's known, it's a bug in Opera when using it with Catalina. It'll be fixed in the next update.

Can you give an example of a site on which video freezes?

Yep, something related to the traffic lights changed in Catalina :). A fix for this is being tested right now and will reach your stable version of Opera soon.

@atls it's probably better if you open a new thread for this, it's not related to the problem described in this thread so far. For those interested, that problem was due to a problem with the Widevine DRM plugin, which is used by e.g. Netflix and Amazon Prime to protect their content, but not by YouTube.

You can change it right in the menu. Click 'Opera', then uncheck 'Warn before quitting (⌘Q)'.
