I want to watch my listings in the last minute but the clock is frozen. If I refresh I get the current time but otherwise the clock doesn't move. This is a recent problem. What do I do to fix it? I use Firefox and I've cleared obvious caches. Thanks ...
I want to prelist and select times happening every three minutes. The new format is based on 15 minute intervals only. What's going on? Why can't eBay just leave well enough alone?
