Yes, if I'm not mistaken, as per info on their telegram channel
https://t.me/dusknetwork/ - DUSK devs temporarily removed the chrome extension as they've already attained quite a significant number of users required to test its implementation but rest assured, they will release a final product to it maybe alongside with its mainnet release.
I hope this really happens, I haven't had a chance to test the function in the browser, and if there is something similar with Mainnet, I fear I will have difficulty adapting. For Tdusk (test) tokens, will there be any conversion to real tokens at some point?
I would rather see them keeping the extension available to everyone who is willing to try it. By doing that, they would get a bigger user base for the upcoming mainnet even thou they got more than enough info from tests.
