1. Having problems with Yandex Market (in all browsers):
GRAY SPINNER. Error in Console:

FF error:
Imagus mod: [rule 774] can't convert undefined to object

EXAMPLES
https://market.yandex.ru/category/dzhempery-muzhskiye

2. Recently, I've been having strange problems with Ozon on many Chromium browsers:

WORKS: Edge 141, FF 145.

YELLOW SPINNER + this console error:
https://s1.directupload.eu/images/251216/4oprekce.png
Chrome 143, Cent 132, Brave 141.

It doesn't seem to depend on the extension; IM has the same errors as IR. Perhaps this is somehow related to MV3 limitations (Edge, like FF, continues to support MV2)?
