Chrome Application Error: Client Side Exception Fix

The “Google Chrome application error: a client side exception has occurred” message means Chrome’s web page or extension code crashed while running in your browser. This is usually fixed by clearing your cache, disabling a problematic extension, or resetting Chrome’s settings, and the steps below walk through each fix in order.

What Does This Error Mean?

When Chrome shows “a client side exception has occurred,” it is reporting that JavaScript running on the page (or in an extension) threw an unhandled error. This is not a problem with your computer’s hardware or your internet connection—it is a software issue inside the browser itself. The error can appear as a full-page white screen, a dialog box, or a small pop-up in the corner, depending on which part of Chrome crashed.

Common triggers include:

• A corrupted cache or cookies for a specific site
• A misbehaving browser extension that conflicts with the page
• Outdated browser version with a known bug
• Corrupted Chrome profile data
• Hardware acceleration glitches with your graphics driver

Most of the time, the error is temporary and a simple refresh will clear it. If it persists, follow the fixes below.

Fix 1: Refresh and Restart Chrome

Start with the simplest action. Press Ctrl+R (Windows) or Cmd+R (Mac) to reload the page. If that does not help, close all Chrome windows completely and reopen the browser. On Windows, make sure Chrome is not still running in the background—check the system tray for a Chrome icon and exit it from there.

If the error appears immediately on startup, try opening Chrome in Incognito mode (Ctrl+Shift+N). If the error does not occur in Incognito, the cause is almost certainly an extension or cached data, which the next steps address.

Fix 2: Clear Cache and Cookies

Corrupted cached files are a frequent cause of client-side exceptions. To clear them:

1. Click the three-dot menu in the top-right corner.
2. Go to More tools > Clear browsing data.
3. Set the time range to All time.
4. Check Cookies and other site data and Cached images and files.
5. Click Clear data.

This will sign you out of most websites, so you may need to log in again. If you want to keep your logins, you can first try clearing only cached images and files, then test the site. If the error remains, clear cookies as well.

Fix 3: Disable Extensions

Extensions run JavaScript in the background on every page you visit, and a single faulty extension can crash pages. To test this:

1. Type chrome://extensions in the address bar and press Enter.
2. Toggle off all extensions one by one, or use the Incognito test from Fix 1 to narrow it down.
3. After disabling all, reload the page that showed the error.
4. If the error disappears, re-enable extensions one at a time until you find the culprit.

Common offenders are ad blockers, privacy tools, and extensions that inject scripts into pages. Once you identify the problem extension, remove it or check for an update.

Fix 4: Update Chrome and Check Hardware Acceleration

An outdated browser can have bugs that are already fixed in newer versions. To update:

1. Click the three-dot menu > Help > About Google Chrome.
2. Chrome will automatically check for updates and install them.
3. Rel launch the browser after the update.

If you are already on the latest version, try disabling hardware acceleration, which sometimes causes graphics-related crashes:

1. Go to Settings > System.
2. Turn off Use hardware acceleration when available.
3. Click Relaunch.

Fix 5: Reset Chrome Settings

If none of the above work, resetting Chrome to its default state can clear hidden corruption. This will disable all extensions, clear temporary data, and reset your homepage and search engine, but it will not delete your bookmarks or saved passwords.

1. Go to Settings > Reset settings.
2. Click Restore settings to their original defaults.
3. Confirm by clicking Reset settings.

After the reset, test the page again. If the error is gone, gradually re-enable your extensions and reapply your settings.

Fix 6: Create a New Chrome Profile

If the error persists even after a reset, your user profile may be corrupted. Create a fresh profile to test:

1. Click your profile icon in the top-right corner.
2. Click Add (or Manage profiles > Add profile).
3. Choose a name and click Done.
4. Switch to the new profile and open the problematic page.

If the error does not occur in the new profile, you can migrate your bookmarks and passwords manually, or simply continue using the new profile. The old profile can be deleted later.

When to Reinstall or Seek Further Help

If the error occurs on every page, in every profile, and after a full reset, the final step is to uninstall and reinstall Chrome. On Windows, use the Add or remove programs settings, check the box to delete browsing data during uninstall, then reinstall from the official Chrome download page. On Mac, drag Chrome from the Applications folder to Trash, then reinstall.

Before reinstalling, consider whether the error appears in other browsers too. If it does, the problem is likely on the website’s side or with your network (e.g., a proxy or firewall injecting scripts). In that case, contact the site owner or your network administrator.

Frequently Asked Questions

Will clearing cache delete my passwords?

No. Clearing cache and cookies does not remove saved passwords. However, if you clear cookies, you will be logged out of most sites, and some sites may require you to re-enter your password even if it is saved.

Does this error mean my computer has a virus?

Not usually. The error is a JavaScript crash, not a sign of malware. However, if you see it constantly on unrelated sites, it is worth running a security scan with your existing antivirus software, but the fixes above resolve the vast majority of cases.

Why does this happen only on one website?

If the error is site-specific, the website’s own code has a bug. You can try disabling extensions that might interfere, but if it persists, the site owner needs to fix their JavaScript. You can report the issue to them.

Will resetting Chrome remove my bookmarks?

No. Resetting Chrome restores default settings and disables extensions, but your bookmarks, history, and passwords remain intact. Only a full uninstall with data deletion removes those.

Is there a way to prevent this error in the future?

Keep Chrome updated, avoid installing too many extensions, and periodically clear your cache. Also, if a particular site consistently triggers the error, consider using a different browser for that site until the site fixes its code.
