Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsStart with a site-specific pause or allowlist, then reload the page. If that does not help, briefly turn off the ad-blocking extension to test whether it is responsible. A broken page can also be caused by another extension, browser protection, stored site data, security software, or the website itself, so work through the checks below rather than disabling protection everywhere.
1. Pause blocking on the affected page
Open the ad blocker’s toolbar menu while viewing the problem page. Look for a control such as “Pause on this site,” “Allow ads on this site,” or “Allowlist.” Labels and scope vary by product; check the extension you actually use, and reload if it does not reload automatically.

For AdBlock’s desktop extensions for Chrome, Firefox, and Edge, “Pause on this site” refreshes the page and adds it to a smart allowlist for seven days. Returning to the site within that seven-day period renews the period. AdBlock’s other allowlisting controls can create an exception for a domain, a set of pages, or one page. See AdBlock’s site-pause instructions and allowlisting instructions.
Recommended Free Tools
uBlock’s support distinguishes pausing uBlock for the current page from allowing ads across the whole site. Choose the narrower page-level option when you only need to test one page; use a site-wide exception only if that is what you intend. See uBlock’s instructions.

2. Test whether the ad blocker is the cause
If the site-specific exception changes nothing, briefly disable the ad-blocking extension and reload the page. This is a diagnostic test, not a recommendation to browse with blocking permanently off. If the page still fails while the extension is disabled, AdBlock’s guidance says the issue is something other than AdBlock. Turn the extension back on after testing. Its desktop help also documents a website troubleshooting tool for its Chrome, Firefox, and Edge extensions.
3. If the warning remains, check other blockers and site data
A site may still detect blocking after you pause one extension because a second privacy or content-blocking control is active. Mozilla notes that extensions that block content, modify websites, or change browser behavior can make pages display incorrectly. Check for extensions that block scripts, ads, trackers, or cookies, then disable and re-enable them one at a time, reloading after each change. This can identify a conflict without leaving every extension off. AdBlock also lists cybersecurity or VPN software, private-browsing settings, and the site’s cookies as possible reasons an anti-adblocking notice persists. See AdBlock’s persistent-warning troubleshooting and Mozilla’s page-display troubleshooting.
Clearing cookies for the affected site is one possible test, but it may sign you out and remove site-specific settings. Use the browser’s site-data controls for that site rather than clearing all browsing data unless you intend to do so.

Firefox: Enhanced Tracking Protection
On the affected page, select the shield icon beside the address bar and turn off Enhanced Tracking Protection for that site. Mozilla says this creates a site-specific exception and reloads the page; protection remains active on other sites. If the change does not help, or you no longer want the exception, turn protection back on from the shield menu. This setting is separate from an extension’s allowlist. Details: Mozilla’s Enhanced Tracking Protection guide.
Chrome: intrusive-ad control
Chrome’s built-in ad control addresses intrusive ads on sites that violate the Better Ads Standards; it is not a general switch for third-party ad blockers. To permit intrusive ads for a trusted site, use Chrome’s site settings for that site and reload. This browser-native permission is separate from an extension allowlist. See Google’s instructions for managing intrusive ads.
5. Compare browsers and isolate the cause
Open the same page in another browser. If it fails in multiple browsers, Mozilla says the website itself is a likely cause. If it fails only in Firefox, continue with Firefox-specific checks. In the affected browser, disable extensions one by one and reload after each change; Mozilla describes this as a way to identify an extension conflict.
Advanced users can inspect AdBlock’s resource page to see requests and how AdBlock treats them, but custom exceptions can break a page if entered incorrectly. Try the built-in pause and troubleshooting controls before editing filter rules. AdBlock documents this inspection at its resource-page guide.
6. Choose the least disruptive fix
| Option | Scope | Best use | What it tests or changes |
|---|---|---|---|
| Pause on one page | Current page; depends on blocker | Check whether blocking affects a particular page | Temporarily changes extension behavior for that page |
| Allow ads on a site | Whole website; depends on blocker | Allow ads across a site you trust | Adds an extension-level site exception |
| Browser-native site exception | One site in that browser | Test Firefox Enhanced Tracking Protection or Chrome’s intrusive-ad control | Changes browser protection, not the extension’s allowlist |
| Disable extensions one at a time | One extension per test | Find a conflict when pausing the named blocker does not help | Identifies whether another extension changes page behavior |
| Compare browsers or contact support | Different browsers or the website | Distinguish a browser-specific problem from a likely site problem | Helps decide whether to continue local troubleshooting or report the issue |
7. Restore your preferred protection or report the problem
When testing is finished, resume blocking or remove any site exception you do not want to keep. AdBlock documents a “Resume Ad Blocking” control and instructions for removing a saved site rule; other products use different controls. See AdBlock’s allowlist guide and resume instructions.
Best Value
If the page remains broken with the extension disabled and fails in more than one browser, contact the website’s support team. Firefox users can also report a broken site to Mozilla where applicable; see Mozilla’s troubleshooting guide.
