Mystery Add-on

[LIMPET235]

So.....
Did I have an extension, way back when, that I deleted the .xpi for or was updated & it's icon/button changed, or was it a built-in feature?
Totally confused.


Q?
How does one check the contents of an .xpi file to see exactly what it was installing?

I checked in one of my V20 back-up Profiles & have about 10 .xpi files that I cannot make any sense of.
Thanks.

&, Would the reason for it being in v50 be caused by my "just transferring a V20 back-up profile" into V50?
I did not install that Undo Close button into V50.
It was not available in the old form that I have displayed, apparently.

xpi's are just .zip files. Copy the xpi, change its extension to .zip, then you can open it with your favorite archive manager.

A quick update...
I just finished checking 45 .xpi files in 2 different Profiles, v20 & v50 & I did not find one that referenced the "Undo Close" or "Undo Close Button"
in any way, shape or form.

So, I am more confused than ever as to where it came from.
I think I may need one of these..


&, yes df, I've had this affliction for, oh.....I forget how long.
