[SOLVED] locate image in Customise Firefox > Overflow Menu

[cubby_sure]

In firefox 57 with photon for linux it looked like:

Maybe I'm sorry I updated, but now in Firefox quantum 61 it now appears like the following. I've only included the right window that shows overflow menu:


Does anyone know where this image would be found?

The following is another similar image that has appeared in the latest firefox versions, this page shows when there is a problem loading a webpage due to server problems:


Just wondered where these anime images are located. I don't see anything in .mozilla/default/prefs.js file. Yeah, they kinda creep me out.

omni.ja. but you should leave it alone, dont mind. for different use copy and extract those file and find the image.

btw current is firefox 62.0.2 you should update your repository because you already missed 62.0 and now your firefox is vulnerable, whether using linux or not.

Thank you both.

@Brummelchen@ for some maybe don't mind. I do mind, in some cultures they can have religious meaning, not a simple image.
