After an update of Debian v.10 it has happened to me that in the browsers, both Chrome, Firefox or Opera, I have lost the Spanish keyboard in the browsers but nevertheless in the OS it is correctly configured because I write in the terminal and I continue to maintain the accents and the eñe without problem.
I have searched in the configuration of the browsers and the Spanish keyboard option is checked but in no way.
I don't know if I'm missing another way to configure the keyboard that all browsers have in common.
Anyone else has happened?
