@leocg To open the image in Opera, I right-click the file in "files" (nemo) and choose 'open with Opera.'

When I try to paste in the full path into the Opera search bar, to open inside Opera, it tells me:

Your file couldn’t be accessed
It may have been moved, edited, or deleted.

 ERR_FILE_NOT_FOUND

Pasting in the full path in Firefox works right.

@leocg To review: my original question was, why does Opera show this strange path when I load an image from my computer and then Opera is not abe to re-open the image when I restart?
The answer is that it's a bug in Chromium, on which Opera is based?

@leocg So, is Opera based on chromium?

@leocg Same result as with Opera.
How is this relevant?

I open a .png file from a sub-directory in Home. When I open it in Firefox, it shows the correct path:
file:///home/eric/Public/Bleak%20Midwinter/Cover/Cover%208%20christmas%20trees%20gold%20with%20seal.png
But when I open it in Opera, it shows this path:
file:///run/user/1000/doc/aMYybcqiqijkJvRuZfSoxg/Cover%208%20christmas%20trees%20gold%20with%20seal.png.
Where does that path come from? Why does Opera do that?

And when I restart my computer and re-open Opera, it says it can't open the file.

I'm using FF 158.0(64 bit) and Opera One(version: 136.0.6008.80) on Fedora 44 workstation edition.
