"Tooltips" in mouseover Topic is solved

[Alpha]

Hello, recently upgraded PM to version 27.9.2 x64.
I have noticed now a small icon appearing when I move the mouse over some elements, see attached image.
In Youtube, if I move the mouse over the video, I get two of them; one is "mediasource" and the other is "@src".
I managed to see the html code in the "Inspect" view, but I do not know where those come from, only noticed a few "id" in the code: "rb-div, rb-menulist, rb-tooltip, rb-data-link and links that go to nowhere.
Is it maybe a new functionality of this version? I was using PM 26.5 version till now and I do not remember having those "tooltips".
Any way to hide it?
Thank you in advance.

That seems like some sort of add-on. Try Help > Restart in Safe Mode... and see if they still appear. If not, restart normally, go to you Add-ons manager, and see if you can find which one is doing it.

If Safe Mode doesn't make them go away, then I have no idea where they could be from.

Thank for your reply, SpockMan02.
You were right, I was using Redirect Bypasser 2.0 which caused those to appear.
Solved now, thank you.

No problem I'm glad you figured it out.
