@yoday Update: I've filed a bug report to Gira systems, Opera GX, let's see if they fix this problem. I appreciate attempt of @burnout426 too, if the problem is getting solved from extension side, it's good.

@burnout426 Thanks for your reply, I understand your point.
The dark mode extension you linked seems to solve the problem but Dark Reader has buttons in the extension options itself, to disable or enable for specific websites, which is very convenient.
I still think it's an Opera GX problem because Dark Mode was completely switched off instead of blacklisting specific websites only, which made sidebar applications look ok.
As far as I understand, the sidebar applications URL is not correctly being delivered to the extension even if it's the same as tab page -- and we can't access extension options for the sidebar application either because the extension button is invisible.
If any of the above points is fixed it should solve the problem.

@omi-kun Yeah I am using Opera GX on laptop, I am unable to understand why does the issue rise on your system. This is weird.

@omi-kun

I get the drop down menu successfully.

I suggest check your computer's language and change it to English (UK) or US maybe.

@yoday Strange, here if I right click on them, I can see the Copy Address option.

Are you also using the Opera GX browser?

@omi-kun said in Disable extensions for sidebar applications.:

@yoday don't worry brother I have solution for u. go to opera://extensions/ or go to manage extension and remove your dark reader and install then night eye and select your want. I suggest for chrome store and run it check setting and set it up. And boom, it's not working on sidebar. That is actually thought I figure out by wasting all my day for this forum. If this helps. So pls help me too here my forum pls help.

OK Thanks a lot, if this does not seem to work I will definitely try Night eye. I will also look at your post and reply if I am able to find something.
Thank you.

@omi-kun But it's obvious that Whatsapp uses web.whatsapp.com and Spotify uses open.spotify.com but for some reason extension does not disable them even after blacklisting the sites.

Screenshots for examples
Dark reader extension options in open.spotify.com web page in tab: https://imgur.com/a/PtbD4tF

Look at the volume slider button for example.

Screenshot of the Player from sidebar:

@leocg WhatsApp, Instagram, and Twitter.

@yoday it all happens may be the sidebar store chache and save them as other way . and its not easy to modify . so brother we have to tell it to devs. not that forum mods.

I think so. Do you know how do I contact devs?

@leocg said in Disable extensions for sidebar applications.:

@yoday Of course you need to have the panel with the messenger opened and right click on that panel.

I tried that too, but if I right click the sidebar application icon while it's open, I get the same options and the sidebar app collapses (or closes).

@leocg
Right clicking a sidebar application does not give me an option to copy its link.

@leocg I understand, but the extension still activates on the sidebar applications and not on the webpage (because it's blacklisted).
Basically blacklisting the webpage is only working on the tab page and not on the sidebar page for some reason.
