Not if it’s a bug or not, but I thought it would be a good idea to report this.
This page for example https://themeforest.net/category/wordpress?utf8=✓&referrer=search&view=grid
It looks different in Firefox as opposed to Chrome. In FF the grid is on 3 columns, and the thumbnails is the actual preview image, and in Chrome the grid is 4 column based, and the thumbnail is the actual product thubmbnail.
Thumbs up for the FF version, thumbs down for them being different
There are a series of different A/B tests running at the moment, looking at things like the category and search pages. There’s some more info here: Further tests on Market Search / Category / Home pages
Thanks for the info If I may, I think it would be a good idea if the entire title of the theme would be displayed, as opposed to having it on a single line and cutting it off.
