Restart Opera
it's sad that Opera AS can’t provide this…

I think the Opera Devs doesn't care what the community wants.

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

For Opera stable version: 88.0.4412.27 (Chrome build 102.0.5005.61)
Go to http://ppa.launchpad.net/canonical-chromium-builds/stage/ubuntu/pool/main/c/chromium-browser/
Search for chromium-codecs-ffmpeg-extra_102.0.5005 (Ctrl+F) and download the following .deb:

chromium-codecs-ffmpeg-extra_102.0.5005.115-0ubuntu0.18.04.1_amd64.deb

direct link

Then unpack the .deb into an empty folder, unpack data.tar.xz there. In the folder /usr/lib/chromium-browser/ is the proper libffmpeg.so.

Copy the libffmpeg.so into the directory /usr/lib/x86_64-linux-gnu/opera/lib_extra/ (If not present, create it with mkdir lib_extra)

Restart Opera and testing:

@Opera Dev: Please update the SourcesList file (e.g. opera-stable.list) in /etc/apt/sources.list.d/ according to the latest Debian specifications. Currently the following notice appears after an Opera update:

Notice: Some sources can be modernized. Run 'apt modernize-sources' to do so.

After apt apt modernize-sources the compliant file opera-stable.sources is created with a warning:

@jedi-am
The Opera developers do not care about the Linux versions of Opera.
I have already pointed out several times (also via bug reports) that there are several errors in Opera (Linux). It will never be fixed.

• Lack of video support due to severely cropped version of libffmpeg.so (Vivaldi fetches the latest from Chromium at startup)
• No saving of window size and position after restart (only Opera).
• Opera does not use the language of the operating system for the user interface. The GUI is only in English.
  I have to start Opera with opera %U --window-size=xxxx,xxx --window-position=xxx,xxx --lang=de

Because of the once again not working videos in Opera Stable (Opera devs shame on you for not supporting the Linux versions), following information for this version:

Try the Chromium package from the Linux Mint upstream.
http://packages.linuxmint.com/list.php?release=wilma#upstream

chromium_121.0.6167.160~linuxmint1+virginia_amd64.deb

unpack this and copy the libffmpeg.so
from /chromium/usr/lib/chromium/libffmpeg.so
to /usr/lib/x86_64-linux-gnu/opera/lib_extra

then restart Opera Stable, this works perfektly from me (Debian/sid).

I found this Info on https://pkgs.org/download/chromium-codecs-ffmpeg-extra

Mit Opera One (Version: 104.0.4944.23) funktioniert die Erweiterung wieder.

@burnout426 said in Opera 103.0.4928.34 Stable Update:

Yes, reinstalling and new Opera profile does not help.

The GMX MailCheck extension no longer works. I can no longer log in to the extension.
https://addons.opera.com/de/extensions/details/gmx-mailcheck/

I think this is related to the automatic change of the Opera profile folder. Before: Default, after: Default.old (GMX MailCheck no works). A new Opera profile has no Default folder.

GMX MailCheck works with Opera Beta and Opera Developer, but both have a Default folder.
