Hi, I have Firefox 102 ESR in Debian 11 (LXC in Chrome OS). It is the en_US version with Czech spell checking dictionary installed as an add-on. I can switch the spell checker from English to Czech in ordinary text areas by accessing the context menu via a right mouse click. However, I'm using a proprietary e-commerce system (Shoptet) with a WYSIWIG editor that has its own context menu, overriding the default one in the browser. I can't switch the language for that reason. Is there a way to switch the spell checker language for a particular text area without access to the context menu? Thank you very much. Petr
