For some strange reason, yesterday Firefox decided that everything I typed was going to come out backwards. As a result, I now have a bookmark folder called siraloSnepO. I still don’t know how it happened. Closing Firefox only cured it temporarily. I knew it had to be something to do with BIDI support, but it certainly wasn’t obvious. Words were being constructed in reverse, but input was still coming from the left of the screen. In other applications, switching to right-to-left makes the cursor appear at the right of a textbox (I verified this in XChat). It seems to have stopped for the time being. I fiddled with some settings in about:config including bidi.support which I set to 3 (disable) which I think may have done the trick. Changing bidi.direction to 2 did have the effect of making text come from the right, so it wasn’t that.

I hope that has cured it. Otherwise, you might find you need a mirror to read my next blog…
