One of the things that I wished Chrome did as standard was the auto reloading of tabs. This is handy for a number of scenarios but I wish to keep myself logged into our Local Authority portal so I get the correct Internet filtering level all the time without having to keep logging in again when the timeout period expires.

There are extensions out there that will do this for you (eg Auto-Reload) but I was alarmed at how all these extensions have access to your website and navigation data. Then I stumbled on a handy hint on a forum that pointed me toward a much better solution. I didn't know this but you can include Javascript in the URL field of a favourite. Therefore you can do the following:

1) Create a new favourite with the URL below:

javascript: timeout=prompt("Set timeout "); current=location.href; if(timeout>0) setTimeout('reload()',1000*timeout); else location.replace(current); function reload(){ setTimeout('reload()',1000*timeout); fr4me='\n'; fr4me+=''; with(document){write(fr4me);void(close())}; }

2) Select the tab you wish to reload, then click on the favourite you just created

3) Enter the number of seconds you wish to refresh the page in.

Et Volia! Refreshed tabs in Chrome!
