Fórum podpory Firefox

ever since i was in Portugal, and a repairman needed my phone to access our contract for a car repair, my web pages constantly show up in Portuguese. no matter what i set my page to, and it SHOWS it is set in English, i still keep getting pages opening up entirely in Portuguese..and have to work my way thru to reset it BACK to English.

what  is going on ?

When Firefox first runs, it works properly. All menus appear properly. At some point after use, a hour or so, all the menus stop appearing. The main menus, right click context menus, hamburger menu, all stop showing up. Even the pull-down menu on this website for "Which topic best describes your question" fails to appear, though I can select an answer by clicking on it and using he down arrow.

Hardware acceleration does not affect it. The problem occurs whether it is on or off. Nothing fixes it except shutting down and restarting Firefox, and that is only a temporary measure, as it inevitably happens again after some use. z

Updating graphics drivers does not fix it. It has been happening over the last three sets of Nvidia driver updates.

Sometimes the menus temporarily return, but soon go away again. They are gone far longer than their short returns.
