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.

Hi @jc1742, the removal of the text encoding menu follows a similar move by the core of Chrome, on which Opera is based. You can read more about the decision and its effects in Google's bug tracker here: https://bugs.chromium.org/p/chromium/issues/detail?id=597488 .

I don't see any extensions in Opera's collection right now that would allow you to change it, but there's an extension to install Chrome extensions here: https://addons.opera.com/en-gb/extensions/details/download-chrome-extension-9/?display=en

After installing that you should be able to use: https://chrome.google.com/webstore/detail/set-character-encoding/bpojelgakakmcfmjfilgdlmhefphglae?hl=en which is an extension allowing you to change text encoding.

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

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.

@nintendork07: I can't reproduce the problem in Opera 71. Does it happen on specific sites or with any video? Can you click the menu item 'View -> Hide Toolbar in Full Screen Mode' when this happens (it should normally be disabled for a full screen video)?

OK, reproduced, the window needs to be in full screen mode already with toolbars set to visible and sidebar set to hidden, then full-screening a video will have this effect. It'll be fixed in the next update.

@andrew84 said in Attach files with wild abandon! Presenting Easy Files:

When uploading images it should show images only, not all the formats including .exe.

It does this. Like the file chooser dialog, it depends on whether the site has said which formats are being handled or all formats are allowed.

@andrew84 said in Opera 73 developer:

@andrew84 it seems that Opera on Presto had this feature since 10th version. Far better solution than the Ctrl+Tab cycler.

They are for different purposes (note that Presto also had a tab cycler). Disclaimer: I've worked on all these features, both the historical ones in Presto and the current ones in Opera.

The tab cycler allows you to switch between recently used tabs. The general idea is that you find the tab you're looking for either immediately (last tab used) or by scanning the first 2-3 items. You can go further if it turns out it's longer ago, but this is the exception, not the rule. Similar to the application switcher in macOS (Cmd+Tab) or Windows (Alt+Tab).

You might not be the type of user that often switches between recently used tabs. That's fine, then Tab Cycler is not for you. It doesn't mean it's not useful for others that do work this way.

Showing thumbnails of tabs on the tab strip allows you to contextually find a tab, especially if you haven't seen it for a while but you have a visual memory of either what it looks like or where in the tab strip it was located. It doesn't help at all to switch quickly between recently used tabs, especially when there are many, but it helps if you're looking for a tab you know is somewhere. Similar to the Dock on macOS or the task bar on Windows, or maybe Expose on macOS.

Opera doesn't have a way to see a thumbnail overview of the whole tab strip right now, but it does have a contextual overview of tabs in Search Tabs. The feature we had in Presto for sure was handy for some people, but the effort needed in making it appear meant that it was tragically underused, and a new effort to bring a tab strip visualization would have to improve on that.

@angrypenguin: This looks like a hardware acceleration problem. What does opera://gpu look like?

Generally this kind of problem can be worked around / fixed in these ways:

1. update your video drivers
2. if it's a common problem with a recent driver, wait for Chromium fix
3. workaround: turn off hardware acceleration in Opera's settings (this will make Opera slower)

@ralf-brinkmann If you downgrade to the version you used before 70.0.3693.0 (probably http://ftp.opera.com/ftp/pub/opera-developer/69.0.3686.0/ ), does it work again?

I tried reproducing this but I can't see it - my (old) bookmarks are autocompleted even though they're not in history. You can also see in the address field where a suggestion comes from if you select an entry with the keyboard. If the icon in the address field changes to a heart, it means it came from bookmarks.

@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

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

@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.

@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.

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