It's very frustrating when i try to change all the languages available to me in the toolbar, but i can only change one of the options, and it's always the rightmost language that gets changed regardless of the one i have selected.
I need the one that i selected to be changed, instead of what's currently happening.
I'm using Firefox on Windows 10.
I have tried hiding the languages that i don't use with UBlock Origin, but that just hides the problem instead of solving it. Didn't try anything else; i would see if there's something i could do directly through the HTML code but i'm not familiar with the language.
