When you use Perplexity for research, the numbered citations next to each answer should be clickable links to the original sources. If the citation numbers are not linking, you cannot verify the information or open the referenced pages directly. This problem usually happens due to browser extensions blocking the interactive elements, a corrupted browser cache, or a temporary glitch in Perplexity’s web app. This article explains why the links stop working and provides clear steps to restore clickable citations in Perplexity.
Key Takeaways: Restoring Clickable Citations in Perplexity
- Clear browser cache and cookies: Removes corrupted data that breaks citation link interactivity.
- Disable ad blockers and script blockers: Stops extensions from blocking the JavaScript that powers citation links.
- Use incognito or private browsing mode: Tests whether extensions or cached data are causing the issue without changing permanent settings.
Why Perplexity Citation Numbers Stop Linking
Perplexity displays citations as superscript numbers next to each sentence in the answer. These numbers are hyperlinked to the source URL using JavaScript event handlers. When the JavaScript fails to execute or the link target is blocked, the numbers appear as plain text instead of clickable links.
The most common technical root cause is a browser extension that blocks scripts or removes interactive elements. Ad blockers, privacy-focused extensions like uBlock Origin or Privacy Badger, and script managers like NoScript frequently strip the onclick events from citation numbers. A corrupted browser cache or an outdated version of the web app can also prevent the links from rendering correctly.
Steps to Fix Perplexity Citation Numbers Not Linking
Follow these steps in order. Test the citation links after each step to see if the issue is resolved.
- Reload the page and refresh the answer
Press F5 or Ctrl+R to reload the current Perplexity page. Then click the Regenerate button below the answer to force Perplexity to rebuild the response with fresh citations. - Open Perplexity in an incognito window
In Chrome, press Ctrl+Shift+N. In Edge, press Ctrl+Shift+P. In Firefox, press Ctrl+Shift+P. Log in to Perplexity in this private window. If the citation numbers become clickable, the problem is caused by an extension or cached data in your regular browser profile. - Disable all browser extensions temporarily
In Chrome, go to the puzzle icon in the top-right corner, select Manage Extensions, and toggle off each extension. In Edge, click the extensions puzzle icon and choose Manage Extensions. Reload Perplexity and test the citations. If they work, re-enable extensions one by one to identify the specific blocker. - Clear browser cache and cookies for perplexity.ai
In Chrome, click the lock icon next to the URL bar, select Cookies, then Remove. For a full cache clear, go to Settings > Privacy and security > Clear browsing data, select Cookies and other site data and Cached images and files, and click Clear data. Repeat the same process in Edge or Firefox using the equivalent settings menu. - Update your browser to the latest version
In Chrome, go to Settings > About Chrome. Chrome will check for updates and install them automatically. Restart the browser after the update. An outdated browser may not support the JavaScript features Perplexity uses for citations. - Try a different browser
If you are using Chrome, switch to Edge or Firefox. If the citations work in the alternative browser, the original browser has a persistent issue that requires resetting its settings or reinstalling it.
If Perplexity Citations Still Do Not Link After These Steps
“Citation numbers appear but are not clickable”
This indicates a JavaScript execution failure. Open your browser’s developer console by pressing F12. Look for red error messages related to perplexity.ai or content.js. If you see a message like “Failed to load resource: net::ERR_BLOCKED_BY_CLIENT,” your antivirus software or corporate firewall is blocking the script. Temporarily disable your antivirus web protection or contact your IT administrator for an exception for perplexity.ai.
“Citations work on mobile but not on desktop”
The desktop browser may have a conflicting extension that does not exist on mobile. Use the incognito test described in Step 2 to confirm. If the mobile version works fine, the desktop issue is almost certainly an extension or a cached script. Clear the cache on the desktop browser and disable extensions as described in Steps 3 and 4.
“Citations stop working after a Perplexity update”
After Perplexity pushes a new version, the browser may serve a cached version of the old JavaScript file that conflicts with the new citation logic. Perform a hard refresh by pressing Ctrl+Shift+R in Chrome or Ctrl+F5 in Firefox. This forces the browser to download all fresh assets from the server.

You can now restore clickable citations in Perplexity by clearing your cache, disabling conflicting extensions, and testing in incognito mode. After applying the fix, verify that each citation number opens the correct source in a new tab. For persistent issues, try a different browser or reset your primary browser’s settings. As an advanced tip, create a dedicated browser profile with no extensions for research sessions to avoid future citation link problems.
