Hello, I'm having some problems with multiple websites at the moment on log in, when i put my personal information and click on the logging button, nothing happens, and i have tried with another browse (chrome), the next action is show a captcha to permit the log in, that can't be shown on Firefox. Some sites are Coursera, this is where i recognized this problem, the other is Good Smile Company (the US version). Can anybody know how to solve this? i want to stay on Firefox for all my internet navigation. Thank you in advance.
