How to find out the latest version of an extension in the official Chrome web store
Head over to the extensions page in the Chrome web store. In the Additional Information section you will find what is the latest version pushed by the developer and when it was done.
How to check the chrome extension version you have currently installed
The quickest way is to copy chrome://extensions/ and paste it in the url bar.
The other option is to click your way through:
1. Click on the three dots in the top right corner
2. More tools
In the extensions page you will not be able to check the current version, nor manually update them before you enable the Developer mode. In the top right corner you will find that option. Don’t worry, nothing else will change and to settings of your browser will go sideways.
Once enabled, you will see next to the name of each extension different numbers. For example 1.8.9 - that is the current version of the extension that is installed on your Google Chrome.
Now, comapre it with the number you found for that extension in the Chrome web store. If you number is lower, for example 1.8.9 and in the webstore it is 1.9.0, you are using the latest version of the software.
Although extensions are being updated automatically, if the developer pushed an update recently and you have not used Chrome for a while, it might take some time the automatic update to take place.
