This extenstion equire licence to work. Found better free extenstion: https://chromewebstore.google.com/detail/mehkpihnggdnfkpghefmkndpmpdcihhn

a b·21 Jul 2026

Complete dishonest and LIES no mention this is a paid product. IT WILL NOT WORK WITHOUT A LICENCE. you really should not BOTHER! downloading. Maybe they should say it's not free at least or offer a pro version. Now I read the review below and it doesn't surprise me. "So disappointed with this - i cannot believe i paid for this. worst purchase i have ever made." seems like a COMPLETE CON, if you cant try before you buy! as you would expect! that = money grabber! BEWARE there are Red flashing lights all over this product. ps- look at how honest CSS Peeper is - follow their example an stop wasting peoples time!
