Can’t you wait a few more minutes to see if anything has been updated on Facebook, Twitter or Google +? Thankfully, for Firefox users, there is a really nice add-on that will check into this for you. Tab Badge will give you uniform notifications of new content in the Firefox tab bar.
Here is a little more about the add-on from the developer:
Adds a small badge to your tabs to alert you to (for example) new messages on Facebook. The badge is also visible when the tabs are pinned so you can see when there’s something new available.
I have to do a lot of checking back and forth on various social networks – so having this feature built right into the browser is very nice for me. If you don’t want to see the badge on a particular website, you can blacklist that website from showing notifications by right-clicking on it.
Want to give it a shot? You can download and install Tab Badge from the Firefox Add-ons website.
