To find a Chrome extension by its ID, open chromewebstore.google.com/detail/ followed by the ID: the store page tells you what the extension is. To see how it has done over time, paste the ID into AppView Find. It opens the extension's page with users, rating and reviews over time, releases and the publisher.
What does a Chrome extension ID look like?
A Chrome extension ID is 32 lowercase letters from a to p, for example aapbdbdomjkkjkaonfhkkikfgjllcleb. It never contains digits or letters after p. Chrome derives the ID from the extension's signing key, so it stays the same across versions and doesn't change when the developer renames the extension.
That format is a quick check for a typo: a string with a digit, a capital letter or a q to z is not an extension ID. If the store link returns an error page, check the ID against this format first.
The ID belongs to the store listing, not to the browser. An extension installed from the Chrome Web Store has the same ID in other Chromium browsers, such as Edge or Brave. Extensions from Microsoft's own Edge Add-ons store have different IDs; Find looks up Chrome Web Store IDs.
Where do you find an extension's ID?
You meet the ID in more places than the store. Chrome loads an extension's own pages and files from addresses that start with chrome-extension:// followed by the ID, so it shows up in error messages, in the DevTools console, in a page's network log and in support tickets. That is often how people end up with an ID and no name.
Where to find the ID itself depends on where you meet the extension:
| Where you are | Where the ID is |
|---|---|
| A Chrome Web Store link | The 32 letters after /detail/ and the extension's name |
| Chrome, extension installed | chrome://extensions, turn on Developer mode; the ID is on each extension's card |
| Chrome's profile folder | The Extensions folder holds one folder per extension, named by its ID |
| AppView | Under the title on the extension's page, with a copy button |
In Chrome, the Details page of an installed extension also shows the ID in the address bar: chrome://extensions/?id= followed by the 32 letters. That is the quickest way to copy it when you want to look the extension up.
How do you find a Chrome extension by its ID?
Once you have the ID, there are four common ways to see which extension it belongs to. They differ in what else you learn:
| Way to look up an ID | What it shows | What it needs |
|---|---|---|
| Store link with the ID | Today's listing: name, users, rating, reviews | Nothing |
| Web search for the ID | Usually the store page, sometimes posts about it | Nothing |
| Chrome's Extensions page | Name, version and permissions | The extension installed |
| AppView Find | Users, rating and reviews over time, releases, publisher | A free account |
For a quick "what is this?", the store link is the fastest answer. A web search for the ID is hit and miss. Search engines index the store page under its ID, so the first result is usually the same listing; the rest are forum threads, bug reports or lists that happen to mention the ID. Chrome's Extensions page knows only what is installed in your own browser profile, but for those it shows the most detail: name, version and the permissions the extension asked for.
The store page only shows today's numbers. AppView Find opens a page that adds the history behind them: how the user count, rating and reviews changed, when new versions came out, and who publishes the extension.
How do you open an extension from its ID in AppView?
Three steps, and the second one accepts more than a bare ID:
- Copy the ID or the link. Copy the 32-letter extension ID, or the whole Chrome Web Store link that contains it. The new store address and the old one both work.
- Paste it into Find. Open Find in AppView, paste what you copied and press Enter. A free AppView account is enough.
- Read the extension's page. An exact ID opens the extension's page straight away, with its users, rating, reviews, versions and publisher.
This is a working copy of Find's search box. Pick an example or paste your own text to see how Find reads it:
A link copied from the address bar works as it is. Find pulls the ID out of the new chromewebstore.google.com address, the old chrome.google.com/webstore one, and a link pasted without https://. The full list of accepted inputs is in how Find works.
What can you learn from an extension's page?
The page Find opens is the same one AppView shows for every extension it tracks:
| Part of the page | What it shows |
|---|---|
| Header | Users, rating, reviews, version, manifest and last update |
| Overview | Languages, size, dates added and updated in the store, website and support email |
| Trends | Users, rating and reviews over time: the last 30 days free, longer periods on Premium |
| Releases | How many versions AppView recorded; the full release history with dates is Premium |
| Publisher | A link to the publisher's page; the full list of its extensions is Premium |
That makes the page a fair first check for an ID you don't recognize in your own Chrome. It shows how many people use the extension, whether that number is growing or falling, how the rating has moved and who publishes it. A large, steady user base and a known publisher read very differently from a new extension whose rating dropped after its last update.
The same page is useful for an extension you are thinking of installing, or one a competitor just launched. The history shows whether its growth is recent or long-running. On Premium, release dates sit on the same chart, so a jump in reviews right after an update is easy to spot.
