Goto the URL opera://flags/#search-in-open-tabs, disable the flag, and restart Opera.

I finally got this to happen to me in Opera GX. I then went to the URL opera://settings/system and enabled "Use DNS-over-HTTPS instead of the system’s DNS settings". Then things starting working. I don't know if that's coincidence or not yet though.

In Opera Developer (68), it has been change to a search icon. You can goto the URL opera://flags/#search-in-open-tabs, disable it and restart to get the old behavior back.

Are you using Opera 68?

Disable opera://flags/#search-in-open-tabs.

In the Opera program files directory, right-click on launcher.exe to create a new shortcut and place it on your desktop. Then, on the desktop, rename it what you want. Then, right-click on the shortcut, goto properties and then the "shortcut" tab. On that tab, modify the target to add the --user-data-dir command-line switch.

For example:

"C:\Program Files (X86)\Opera\launcher.exe" "--user-data-dir=C:\Users\yourusername\Opera2"

(I personally have a "My Program Files" folder in "C:\Users\myusername", so I'd use "C:\Users\myusername\My Program Files\Opera2" for example.)

You can create as many shortcuts as you want with each using a different profile folder.

See http://peter.sh/experiments/chromium-command-line-switches/#user-data-dir for more info.

To enable password importing, you need to start Opera with the --enable-features=PasswordImport command-line switch.

For example:

"C:\Program Files\Opera\launcher.exe" --enable-features=PasswordImport

Goto the URL opera://about to see the "install" path to see what the path to your launcher.exe is. You can then run that command in a command prompt or modify the properties of Opera's shortcut to pass that switch to launcher.exe.

Then, in Opera, you can goto the URL opera://settings/importData and import your passwords from Chrome. But, you need to make sure Chrome is closed when you do it.

Or, if you want to import the csv file, you can then goto the URL opera://settings/passwords and the "import" option will be available.

The setup I did for Opera Stable (66) for libffmpeg and Widevine on Linux Mint 19.3 XFCE is this:

• Install Google Chrome and Opera.

• Create "/usr/lib/x86_64-linux-gnu/opera/lib_extra"

• Place libffmpeg.so for Chromium 79 in the "lib_extra" folder. Got it from https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases/tag/0.43.6.

• Copy "opt/google/chrome/WidevineCdm" to the "lib_extra" folder.

• Edit "/usr/lib/x86_64-linux-gnu/opera/resources/ffmpeg_preload_config.json" to be:

  []
  

• Edit "/usr/lib/x86_64-linux-gnu/opera/resources/widevine_config.json" to be:

    [
        {
           "preload": "/usr/lib/x86_64-linux-gnu/opera/lib_extra/WidevineCdm"
        }
  
    ]
  

• Uninstall Chrome and delete "/usr/lib/chromium-browser" for good measure.

In testing, unlike "lib_extra" for ffmpeg, Opera does not not search for the Widevine lib or the Widevine folder in any other place besides what's in widevine_config.json. It doesn't even search in "~/.config/opera/WidevineCdm".

(See https://forums.opera.com/post/199264 (my reply/question to @jimunderscorep) for why I edited the config files so Opera only searches for its own copies of libffmpeg and widevine.)

The feature was called Instant Search and Opera removed it.

opera://settings/searchEngines

https://translate.google.com/#auto/th/%s as the search URL should work.

Not the same, but you can hit alt + d (or ctrl + l) to focus the address field, type your search and hit alt + enter. Then, you can hit ctrl + w to close the search result page when you're done to go back to where you were.

Of course, you can just do ctrl + t, type, press enter and do ctrl + w after that instead if that's easier. Again, not the same, but...

Creating thread.

I don't think there's a way. But, since Opera gets that setting from Chromium, if you search for solutions on the net for Chrome and Chromium, and find one, it will probably work in Opera too.

Option is coming. See https://forums.opera.com/post/254447.

In Opera Developer, at the URL opera://settings/keyboardShortcuts, there's now "Switch to last tab". There's no shortcut set for it by default. But, to match other browsers, you can delete ctrl + 9 from "Switch to ninth tab" and add ctrl + 9 to the new "Switch to last tab".

On the full history page (opera://history), you can right-click an entry and choose "add link to bookmarks". It will automatically add the bookmark to the bookmark folder you saved to last. And, it will automatically use a name for the bookmark based on the time, domain, title, and query string etc. of the entry so that the bookmark has a unique name. And, if you right-click on a history entry that's already been added as a bookmark, the menu will show a "remove" option to un-bookmark it.

Perhaps items in the history panel could have that option too.

As for dragging, if you drag down on a link on the opera://history page, drag it till its over the bookmarks panel so that it shows, and continue dragging till it's over a bookmark folder (where the folder is then highlighted), and release, the entry will be bookmarked (with no time info for the name though). It just doesn't work from the history panel, which would be nice.

@operah I have an extension at https://www.reddit.com/r/operabrowser/wiki/opera/extensions/mask_as_chrome that removes Opera's part from the user agent so that Opera appears to be Chrome on whatever platform you're on. It works for all sites by default, but you can adjust that via the "site access" settings for the extension at the URL opera://extensions.

Another way to mask as Chrome is to goto the URL opera://flags/#freeze-user-agent, enable the flag and restart Opera. Then, there's no need for an extension.

You can also specify any user agent string you want for Opera via the command line as mentioned on this page.

Since it seems dr34polw is no longer engaged, I wonder if it would make sense for you to create a new extension.

Thanks. I thought about it, but I don't really want to keep updating the the user agents either. It's a never-ending task. It'd make more sense to have the extension reference a site like https://developers.whatismybrowser.com/api/features/web-browser-version-numbers that keeps the list of strings up to date. Not sure if there's a free list anywhere. That one cost money.

Not only that, but Chrome's x64 Windows user agent is the only one that's really useful in Opera. The other methods mentioned above already satisfy that. Also, this dr34polw extension allows you to specify a custom string right in the extension options in the user interface.

For the opera://bookmarks page at least, you can right-click a bookmark and choose "copy". That will copy the bookmark's URL to the clipboard where you can then paste it.

The copy command in this case is more for copying a bookmark so that you can paste a copy into another bookmark folder. But, because of the way copy and paste for a bookmark works on the bookmarks page, it'll work as just a URL copy too.

Unfortunately, "copy" for a bookmark is only available on the opera://bookmarks page.

@operah. I updated the user-agents for Chrome, Edge, Firefox and Opera for Windows for this extension. I left the rest alone. Download my zip file and extract it to a place you want to keep the extension folder.

Then, in Opera, goto the URL opera://extensions, disable/uninstall the version of this extension from addons.opera.com.

Then, (while still on the opera://extensions page), enable developer mode, click "load unpacked", and point it to the extension's folder (specifically, the folder where manifest.json is at). That will load my updated version of the extension.

In the lib/config.js file in the extension folder is where the user-agent strings are specified. You can edit them to your liking and then just click the reload button next to the extension on the opera://extensions page and then reopen any existing tabs you have open or restart Opera.

@andrew84, https://forums.opera.com/topic/48169/breadcrumb-path-rendered-in-wrong-encoding-at-opera-bookmarks is fixed now in stable.
