In the last week or so (can't say exactly how long) when my computer wakes from sleep. Firefox seems to have difficulty reconnecting to pages that are already open, often showing an error message, and shows a 'connecting' message for ages when I refresh. Even if I close the tab and open a new one, it still struggles.
The only way to avoid this is to close Firefox and open it again and the problem ceases. I've been using Firefox for years without this ever happening before, so is anyone aware of any change? Using Firefox 25.0.1
No other recent changes to hardware or software.
