19/02/2025. It don't work in edge browser
Superb, works like a charm
The extension is great. But it would be even better if the dimensions of each box is shown on top of the boxes.
Works but if you aren't seeing the black bar at the bottom telling you what you're hovering on you have to inspect and under styles in the tools uncheck the visibility css attribute. For whatever reason it is defaulted to hidden. Very dumb.
I'm a Mac User. If anyone has an issue that feels not working/ hovering effect not works even Debug CSS active, You have to do a simple thing. Go to manage extension --> Turn ON "Allow access to file URLs".
делает своё дело на отлично
Very useful, the best extension compared to others that do the "same" job.
very useful and interactive.
MacBook doesn't work but Windows can.
hey it was working so fine before but now it seems the hover effect has been removed so...will it ever come back?...or is it still there but not coming in mine?
