Please fix the frame around the back button.

Good day! Today after installing your add-on for Mozilla Firefox I noticed one bug:
the frame or circle (I don't know exactly what to call it) disappeared around the "Back" button. Previously, for example, in Mozilla Firefox 78.15.0 ESR there was a huge circle familiar to many. Please fix this bug in the new versions of your add-on. I checked it a few hours ago on Mozilla Firefox 133.0.3, the same story there. I would be extremely grateful!

Proofs:
It was (and should be) like this...

Now it is like this...

Hurrah! I found the solution!
So, the problem is solved as follows:

1. Go to the ./resources folder of the add-on;
2. Open the file "tabs-and-urlbar.css" with any code editor (preferably);
3. Look for the comment /* Photonizes the back button */ (approximately line 420);
4. Immediately after > image {, on the next line (423 in count) insert the following: border: 1px solid #b1b1b2 !important;;
5. Save, close, restart the browser. Done! ;)

And here is the full block "Photonizes the back button" (if anyone needs it):

/* Photonizes the back button */
:root:not([uidensity="compact"]) #back-button {
	> image {
		border: 1px solid #b1b1b2 !important;
		border-radius: 50% !important;
		background-color: #fefefe !important;
		outline: var(--photon-back-outline) 1px solid;
		box-shadow: 0px 0px 4px var(--photon-back-shadow) !important;
		transition: box-shadow var(--photon-speed-1) var(--photon-easing-function) !important;
		margin-left: 1px !important
	}
	&:not([disabled]) {
		&:hover > image {
			background-color: #fefefe !important;
			box-shadow: 0px 0px 5px var(--photon-back-shadow-hover) !important;
		}
		&:active > image {
			background-color: #cfcfcf !important;
			box-shadow: 0px 0px 5px var(--photon-back-shadow-hover) !important;
		}
	}
}

Seems like something broke the code relatively recently and I just didn't notice since I use the dark theme where the outline isn't very noticeable... (right after a release too :p)

Anyways, a much simpler and better solution is to add !important to the end of outline: var(--photon-back-outline) 1px solid.
like this:
outline: var(--photon-back-outline) 1px solid !important;

I've already fixed it in the rolling release and webextension versions, not sure if I'm gonna make a re-release for the static release version tho.

Perhaps, yes, you are right. Thank you for the comment.😅
