After the latest upgrade (86.0.4363.23) on kde neon Opera is once again unable to play any sort of video it seems.
Any thing on Youtube simply crashes the page entirely.
Come on guys, this has been a problem for years now. What gives?
I have tried the usual
sudo cp .local/lib/vivaldi/media-codecs-b647ccfd4aea97d646a09a82b06a46e617c55c2a7781697ac2dea35061aec9d6/libffmpeg.so /usr/lib/x86_64-linux-gnu/opera/
but this hasn't fixed the issue this time.
What's the fix now please?

@valdineidossantos I'd love too, but can't for the life of me work out how to edit the post 
I'll keep looking.
Found the problem.
I had copied the profile from a previous system and thought I had changed the ownership of the .config directory to my user.
Turns out I hadn't.
Now that I have, not only is the chorme extension working, but my entire old setup is back!!
Thanks for the input.

It seems all of my chrome extensions are constantly throwing errors about Corruption (but seem to be working).
Its really really noisy in the logs

with thousands of these every day.
Version info is
Version:95.0.4635.46
Opera is up to date
Update stream:Stable
System:KDE neon 5.27 (x86_64; KDE)
Chromium version:109.0.5414.120
Any clues as to what might be going on? I tried re-adding one of the extensions after I killed it by deleting the "corrupted" directory and the same thing is still happening.
TA.

@pnunn Does anyone have any ideas here?
Is it possibly a permissions thing? Every time I start Opera its asking me about providing feedback which I answer each time but that doesn't seem to be recorded either.
If so, where would I look at the permissions?
@pnunn Seems I can't edit this any more, but for more information. I thought it might have been a permissions issue on the underlying OS, but after checking that all of that looked to be OK, I tried again and this is the error that eventually comes up.
For some reason, when I click on install, opera tries to download the file (I assume with the extension code) and then blows up with the error above.

I'm trying to recover a crashed computer and have installed opera 92.0.4561.30 on KDE Neon but am unable to install any chrome extensions.
When I click on the install button it opens a file dialogue box and tries to, I think, download a file which fails with an error about not having permission to write to the location.
I've never seen Opera do this before.
It doesn't seem to matter which extension I choose, they all do the same thing, but dashlane is the one I'm particularly desperate to install.
On a side note, when I try and log into the forums from opera itself, the login is successful, a redirect page comes up and suddenly Opera dies, and restarts back at the initial setup sequence. So I'm forced to post this from firefox.
Something is very odd here.
Any ideas please?
Peter.

@ticianolima
I'm glad I'm not alone 
I've tried all of the documented fixes and so far nothing works.
Very tiresome.

Hi @kacehik223,
I think I've got this working.
Found a post about changing libffmpeg.so (of course I can't find it now).
I copied the one from /var/opt/vivaldi/media-codecs-[bunch of numbers]/libffmpeg.so to /usr/lib/x86_64-linux-gnu/opera/
Give that a go and see how you go (I think the important thing is libffmpeg from a media-codecs directory.
