I upgraded to the newest version of Firefox over the weekend, and now the mouseover thread preview isn’t working – there’s a teeny-tiny box below the cursor, but there’s no text in that box.
Is this something I can fix? (Guess I could ask in GQ, but this is the only place I use mouseover preview regularly.)
I upgraded to the latest firefox and now the mouseover just stays as long as the cursor is over the post. It’s nice to not have to quickly skim it now and be able to read the whole thing.
It’s possible your profile got corrupted in the upgrade. You can try out a new profile and see if that fixes it. If it does, you can use the official guide to move the important stuff from your old profile to the new one, and then delete the old one.
Once upon a time I had an add-on that allowed the mouseover preview to stay as long as you moused over (pretty sure I got it from the SDMB). Don’t know what it was called, but I wish I did.
