The title pretty much says it. On some phpBB forum I am member of, since yesterday, I can't write long messages and see what I'm writing. When my texte is bigger than the default frame, the scrollbar jumps at the top of the post while i'm still writing. This doesn't happen with other browers on same webpage. Possibility : the deepl addon i just installed ? Any idea ? (sorry if i'm not clear enough, english is not my first language)
