@andrew84 Obviously. And it's related to a recent Opera update because there were no other changes with my Windows theme. How else are we to report trouble like this so that they actually respond with a solution - or at least a hope of one?

A few days ago all the backgrounds for my "bubbles" for my Speed Dial buttons changed from dark to light (Note the red "X" in the attached screenshot). I'm using Opera's Dark theme, and the page background is dark - as it used to be. How do I change them back to dark?
Using:
Opera One(version: 115.0.5322.68)
Opera is up to date
Update stream:Stable
System:Windows 11 64-bit
Chromium version:130.0.6723.59

Is there a way to force dark theme for a single site? Maybe something like a "switch" at the end of a URL?

1. Most sites support Opera's Dark Theme seamlessly.
2. One of my regular sites doesn't support it unless I force dark theme.
3. Once I force dark theme, some sites that displayed dark theme OK before now are messed up.

I've read in an older thread (yes, they are sometimes helpful) that I can right-click on a page and see an option to enable or disable dark theme for that page. That seems to be the case only when force dark theme is enabled in settings.

@leocg Not quite - I have Excel files on my laptop, but would like to create a bookmark with a local link e.g. "file:///c:..."), but while I can use Opera with that format to drill down to the appropriate subfolder, when I click on a selected file it only prompts me to download it - not open it.

Maybe there's another extension or maybe a plugin available that I haven't found yet???

Is there a way to open Excel files from Opera on a Windows PC ?
I've tried the legacy "Documents" extension (latest revision was 2014!), but it doesn't seem to work in current Opera versions.

Never mind - I just found it. It's the "Privacy Protection" button (the shield with a check mark inside it).

Is there a way to add a button or something to the Menu bar to easily add a current site that I'm visiting to Ad Blocking Exceptions? (Something like the "heart" symbol to add a current site to Bookmarks)

The new Opera One(version: 100.0.4815.31) is missing the beloved Speed Dial button on the previous defaulted top left area of the browser. How do I get it back so that it's presence is persistent and not just a one-timer set as a browser app start page?

Is there a way to create an exception and keep login-related cookies for specific sites when I clear "all" history/cookies/browsing data?

How do I view my synchronized devices from both Windows and Android?
