Firefox version 54.0.1 (32-bit) stopped recognizing characters typed with Alt key e.g. "Alt + a" used to produce Polish character "ą" - not any more. I should mention that all other software on my PC (other browsers and applications) continue to recognize this type of typed in sequences (Alt plus characters such as: a, c, e, l, n, o, s, z, x resulting in characters: ą, ć, ę, ł, ń, ó, ś, ż, ź - I did not type the latter sequence, I copy it from Notepad). I must add that this a new problem. I use Firefox browser for ages and I have not seen this problem ever before. Looking forward for a quick and effective solution. ZbyszekO

Do you have multiple keyboard layouts installed?

It is possible that the keyboard layout has been switched accidentally by using the key sequence to rotate the keyboard layout.

Windows remembers the keyboard layout setting per application and you may have changed the keyboard layout by accident via a keyboard shortcut.

My keyboard generates all the characters I type, including "Alt + a", correctly and all other browsers and applications exhibit no problems. Therefore, the issue is with the Firefox. As a proof, I am responding to your answer using Chrome and I have no problem to type in Polish characters ąćęłńóśźź (<- typed in) !!! while with the current version of Firefox, I won't be able to do this.
