Perplexity ‘Browser Not Supported’ Error: Workaround

You try to open Perplexity in your browser and see a message that your browser is not supported. This error usually appears when your browser is outdated, lacks certain web features, or has security settings that block Perplexity scripts. In some cases, the browser itself is not on the official supported list but can still run the site with a small adjustment. This article explains why the error occurs and provides three workarounds to access Perplexity from an unsupported browser.

Key Takeaways: Fixing the Browser Not Supported Error on Perplexity

  • Update your browser to the latest version: Most unsupported errors disappear after installing the newest browser update.
  • Enable JavaScript and WebAssembly in browser settings: Perplexity requires these technologies to load its interface and run AI models.
  • Use a Chromium-based browser as a fallback: Chrome, Edge, Brave, or Opera are fully supported and rarely show this error.

Why Perplexity Shows the Browser Not Supported Error

Perplexity is a web application that relies on modern browser features to function. The site uses JavaScript for real-time search, WebAssembly for AI model processing, and Service Workers for offline caching. When a browser cannot run these technologies, Perplexity blocks access and displays the error message.

The most common root causes are:

Outdated Browser Version

Perplexity requires a browser released within the last two major versions. For example, if you use Chrome 90 in 2025, the site may refuse to load because the JavaScript engine lacks modern APIs. The same applies to Firefox, Safari, and Edge. Browser vendors release security and compatibility updates every few weeks. Running an old version is the number one cause of this error.

Disabled JavaScript or WebAssembly

Perplexity cannot render its interface without JavaScript. Some users disable JavaScript for privacy or performance reasons. Others use browser extensions that block scripts by default. WebAssembly is a binary format that allows Perplexity to run AI models faster than plain JavaScript. If WebAssembly is disabled or unsupported, the site will not load.

Unsupported Browser Engine

Perplexity officially supports Chromium-based browsers (Chrome, Edge, Brave, Opera), Firefox, and Safari. Browsers with different engines, such as Internet Explorer, Pale Moon, or text-based browsers like Lynx, are not supported. These browsers lack the necessary APIs and will always show the error.

Corporate or School Firewall Restrictions

In some cases, the error is not about the browser itself. Network administrators block certain web technologies through a proxy or firewall. If your browser is up to date and JavaScript is enabled, the error may come from your network. Try accessing Perplexity from a different network, such as your home Wi-Fi or a mobile hotspot.

Steps to Bypass the Browser Not Supported Error

Try these workarounds in order. Each one addresses a different root cause. Test after each step to see if the error clears.

Workaround 1: Update Your Browser to the Latest Version

  1. Open your browser’s settings menu
    Click the three-dot or three-line icon in the top-right corner. Select Settings or About.
  2. Check for updates
    In Chrome, go to Settings > About Chrome. In Firefox, go to Settings > General > Firefox Updates. In Edge, go to Settings > About Microsoft Edge. In Safari, updates come through macOS System Settings > Software Update.
  3. Install the update
    If an update is available, click Update or Restart to Update. The browser will download the update and restart.
  4. Reload Perplexity
    After the browser restarts, navigate to perplexity.ai and check if the error is gone.

Workaround 2: Enable JavaScript and WebAssembly

  1. Open browser settings
    Click the menu icon and select Settings.
  2. Find the JavaScript setting
    In Chrome and Edge, type JavaScript in the settings search bar. Click Site Settings > JavaScript. Ensure the toggle is set to Allowed. In Firefox, type JavaScript in the search bar and click Permissions > JavaScript. Ensure the checkbox for Enable JavaScript is checked. In Safari, go to Safari > Settings > Security and check Enable JavaScript.
  3. Enable WebAssembly
    WebAssembly is usually enabled by default. In Chrome, type chrome://flags in the address bar. Search for WebAssembly and make sure the flag is set to Enabled. In Firefox, type about:config in the address bar. Search for javascript.options.wasm and set it to true.
  4. Disable script-blocking extensions
    Extensions like NoScript, uBlock Origin, or Privacy Badger may block Perplexity scripts. Click the extension icon in the toolbar and temporarily disable it for the Perplexity site. Alternatively, open the extension settings and add perplexity.ai to the allowlist.
  5. Reload Perplexity
    Press Ctrl + R or F5 to refresh the page.

Workaround 3: Switch to a Chromium-Based Browser

  1. Download a supported browser
    If your current browser is unsupported (for example, Internet Explorer or a very old Firefox), install a Chromium-based browser. Download Google Chrome from google.com/chrome, Microsoft Edge from microsoft.com/edge, or Brave from brave.com.
  2. Install the browser
    Run the installer and follow the on-screen instructions. Choose the default settings unless you have specific preferences.
  3. Open Perplexity in the new browser
    Launch the browser, go to perplexity.ai, and log in. The error should no longer appear.

If Perplexity Still Shows the Error After These Fixes

Perplexity Shows Error on Mobile Browser

Mobile browsers like Safari on iOS and Chrome on Android are fully supported. If you see the error on mobile, update the browser through the App Store or Google Play Store. On iOS, ensure you are not using a third-party browser that uses a restricted WebKit version. For example, Firefox on iOS uses Safari’s engine and may show the error if Safari itself is outdated. Update iOS to the latest version.

Error Appears After a Browser Extension Update

Some extensions update automatically and may change their blocking rules. If Perplexity worked before but now shows the error, open the browser in incognito or private mode. If the error disappears in private mode, an extension is the cause. Disable all extensions, then re-enable them one by one to find the culprit. Keep the extension disabled or add an exception for Perplexity.

Corporate Network Blocks Perplexity

If you are on a work or school network, the IT department may block Perplexity at the firewall level. In this case, no browser workaround will help. Contact your network administrator and ask them to allow perplexity.ai and all subdomains. Alternatively, use the Perplexity mobile app on your phone over cellular data.
