I am a Taiwanese user. When I want to type something in Mandarin at address bar, I press ctrl+space or ctrl+shift to change the IME. before FF version 44.0 , it was smooth and good as the Right part of the picture. the symbol in the picture means the IME is working at Mandarin mode automatically. after some version updated , it became like the Wrong part of the picture. the symbol in the picture means the IME is working at English mode automatically. that makes me furious. I have to press shift EVERY TIME after I press ctrl+space to change the IME. And it only happens at the address bar. Could somebody help?
