Capmoster cloud. Newest version just downloaded from the page.
Now it does not open at all. Using action or from the toolbar, i press open and extension pop-up just blinks or shows for half second and then disappears. Can't get it working. When this blink is happening, some requests in the traffic monitor pointed to extension also blinks and then disappear.
BTW thats happed with other captcha solving extension so its not extension per se related.
