There are 188,620 extensions available on the Chrome Web Store, and while you might think this provides a wide variety of choices for Chrome users, in reality, most of these extensions are dead or dwindling, with very few having active installations.
All in all, about 50% of all Chrome extensions have fewer than 16 installs, meaning that half of the Chrome extension ecosystem is actually more of a ghost town, according to a recent scan of the entire Chrome Web Store conducted by Extension Monitor.
Further, 19,379 extensions (just over 10%) have zero installs, and 25,540 extensions (13% of the total) have just one user.
The scan found that there are very few Chrome extensions that managed to establish a dedicated userbase.
According to Extension Monitor, around 87% of all extensions have fewer than 1,000 installs, a number that many extension devs would consider a failure, taking into account that the Chrome browser has over one billion monthly active users, a huge potential market for any extension developer.
Only 13 Chrome extensions have over 10 million users
At the other side of the spectrum, only 13 extensions have managed to break over the 10 million mark -- the highest user count threshold available on the Chrome Web Store.
Those 13 are Google Translate, Adobe Acrobat, Tampermonkey, Avast Online Security, Adblock Plus, Adblock, uBlock Origin, Pinterest Save Button, Cisco Webex, Grammarly for Chrome, Skype, Avast SafePrice, and Honey.
There are a few extensions that are getting close to the 10 million threshold, such as the ones listed below, but the number of extensions with multi-million userbases is still quite small, especially when we compare Chrome extensions with Android apps, Google's other successful ecosystem, also with over one billion monthly active users.
