ROBLOX+ is a free Chrome extension on the Chrome Web Store made by WebGL3D. The extension gained popularity for having an automatic signature feature which enabled users on the Forums to just paste their signatures into the box, as people did not like to add their signatures manually.
ROBLOX+ has gained attention more recently for having an update with YouTube embedding. On the night of 8/26/15, WebGL3D's extension allowed YouTube embedding but was reverted back to no embedding after several Forumers were sharing inappropriate YouTube links. On the next morning, ROBLOX+ had a new update which had embedded decals and audios. The update sent OT into a frenzy and YouTube embedding was re-introduced. Some oters hate this update due to the craziness of siggies. An example of the embedding update can be found here.
