Usually has it's problems like mixing tabs but for the most part improves twitter browser version greatly. Not too great lately though, since prob 2 weeks ago it's having issues where it just keeps looping post and doesn't load up past or less than 10 post in the following section or retweets tabs more around night times for some reason but I've noticed regular browser version having issues too. Could be Firefox thing? idk I just wish they looks it up and comeback to being functional. Tl;Dr: Would give 4-5 stars but it has not been so good lately.
