Hi, I'm a Korean user and after updating Firefox into 65, firefox highlights all writting things in lightblue and autocorrects everything as if I have forgotten to press English->Korean switch button. For example when I type "Spark" it translates this thing into "Spa가" because '가' is a postposition in Korean language. This is nonsense and I checked option and here are the things I have turned off. 1. General->Language-> Check your spelling as you type 2. General->Firefox updates-> automatically update search engines 3. General->Browsing-> Search for text when start typing 4. General->Browsing-> Recommend extensions as you browse 5. Search->Default Search Engine-> Provide search suggestions 6. Search->Removed one-click search engines 7. Privacy and security->Address bar->browsing history And this bluelight still keeps following what I type even after I turned off all these things and corrects English into some Korean nonsense, Only addons I have is Adblock and right to click. Is there someway to disable this feature? Thanks for reading.
