If a site makes you tick Cloudflare's "Verify you are human" checkbox every time you visit, the Auto-check Cloudflare option in the 77Fox browser extension can click it for you, aiming to do so within a second of the box becoming clickable. It clicks the official Cloudflare checkbox once, only in the tab you're looking at, and it can't guarantee that you pass; the CAPTCHA recognition module it belongs to is off by default. The extension needs 77Fox for Windows, which walks you through loading it into Chrome 121 or later (it isn't in the Chrome Web Store), and the feature is free.
When the same site asks several times a day, you end up hunting for that small box every time. The idea here is modest: save that one click for you, the person reading the page. You were going to click the box anyway; now the extension does it, the same number of times. Whether a site asks you to verify, and whether it lets you in afterwards, is still up to the site and Cloudflare.
Why the same site keeps asking you to verify
"Verify you are human" is a check Cloudflare runs on sites that use its protection. Whether it appears, and how often, depends on the site's own settings and on how Cloudflare reads your visit.
If the checkbox keeps coming back on one site, or you seem stuck in a "Verify you are human" loop, the common causes include the ones below. Treat each one as a "maybe", not a diagnosis.
| Common cause | What it may do | What you can check first |
|---|---|---|
| A proxy or VPN is on | Many people may share the same exit IP, so sites may ask more often | Compare how often it appears on a direct connection |
| Cookies are cleared or blocked | Sites usually remember a completed check in a cookie; if the cookie is gone, you may be asked again | See whether Chrome clears cookies when it closes, or blocks this site's cookies |
| Privacy extensions | Extensions that block parts of a page or change what the browser reports may lead to more checks, or checks that keep failing | Disable them briefly and visit again |
| The PC clock is off | A large time difference can make the check go wrong | Turn on "Set time automatically" in the Windows date and time settings |
| An outdated browser | Older versions may not be fully supported | Update Chrome |
If the checks got more frequent after you turned on a proxy or switched networks, start with the first row. How these factors are weighed is up to the site and Cloudflare, and 77Fox can't change whether you get asked. The extension does one thing: when the checkbox appears, it clicks it.
What Auto-check Cloudflare does and doesn't do
In one line: on the page you're looking at, it clicks the official checkbox once and leaves everything else alone.
| Does | Doesn't |
|---|---|
| Recognizes only Cloudflare's own checkbox, the one served from challenges.cloudflare.com | Touch the page's own checkboxes, such as "Remember me" on a sign-in form |
| Clicks only while the tab is in front and the checkbox is visible and uncovered | Act in a tab you've switched away from, or on a box hidden behind a pop-up |
| Aims to click within a second of the box becoming clickable | Keep clicking the same challenge: each challenge gets one click |
| Clicks the checkbox through Chrome's debugger permission, without moving your mouse pointer | Change the verification result, submit a form or sign you in |
| Works inside your browser, without going online or uploading anything for this feature | Guarantee a pass, or deal with a different challenge that Cloudflare shows instead |
Right before clicking, the extension checks again: the box must still be in the same place and still uncovered, the switch must still be on, and the tab must still be in front. If anything has changed, it holds off and looks again shortly; it clicks only once everything is back in order, and still no more than once per challenge.
Two more details are worth knowing.
First, it doesn't need the local recognition runtime. Reading text, slider and click image CAPTCHAs requires a runtime you install from the desktop app; the checkbox doesn't use it, and its switch works independently of the Click option for image CAPTCHAs.
Second, it lives inside the CAPTCHA recognition module. With the module off, it does nothing. With the module on, Auto-check Cloudflare is on by default and can be switched off on its own. The switch is in the extension pop-up and in the extension's full settings.
For how 77Fox brings SMS and email codes into the browser, and why image CAPTCHA recognition stays on your device, see iPhone SMS codes on Windows, and local CAPTCHA. The module itself is described on the browser extension page.
How to turn it on
- Install the extension. Install 77Fox for Windows from the download page. In the desktop app, open Settings, go to Browser extension → Install & service and follow the three-step manual install guide: open the extension folder, paste the extensions page address into Chrome's address bar, then turn on "Developer mode" in the top-right corner, click "Load unpacked" in the top-left and select the 77Fox extension folder. Chrome 121 or later is required.
- Turn on CAPTCHA recognition. Click the 77Fox icon in Chrome's toolbar (right after installation it sits in the puzzle-piece Extensions menu, so you may want to pin it), choose Scan in the pop-up's left-hand menu and switch on Automatic recognition.
- Check that Auto-check Cloudflare is on. It sits directly below Automatic recognition and is on by default once the module is on; while the module is off, the switch can't be changed. When it's on, the status line at the foot of the pop-up says so. If the Local recognition runtime row in the same panel says the runtime isn't installed, that doesn't affect the checkbox. If the checkbox is all you want, untick Text, Slider and Click under Recognition types; Auto-check Cloudflare keeps working.
- Add sites to the blacklist if you need to. Click the gear icon next to your avatar at the top of the pop-up to open All settings, go to CAPTCHA recognition and add one domain per line under Site blacklist, for example
example.com. Subdomains are included. Sites on the list are never scanned for CAPTCHAs, and their checkboxes are never clicked.
You can switch Auto-check Cloudflare off in the pop-up at any time. Switching off Automatic recognition stops the whole module.
The debugging bar Chrome shows
The first time it happens, it can look alarming: at the moment of the click, Chrome shows a bar across the top of the window saying, roughly, that "77Fox" is debugging this browser.
That's down to how the click is made. The extension uses Chrome's debugger permission to send that one click, which is why Chrome shows the bar, and it disconnects as soon as the click is done. Slider and click image CAPTCHAs use the same permission and also disconnect after each action. No other part of the extension uses it.
If you'd rather not see the bar, there are two levels of off switch. Turn off Auto-check Cloudflare and the checkbox will no longer trigger it. If you don't use slider or click recognition either, turn off Automatic recognition, and the extension stops using the debugger permission altogether.
FAQ
Could a site ban my account for using this?
77Fox can't make promises on behalf of any site. The feature clicks the box you were about to click, once per challenge, in the tab you're looking at. What happens after that click is decided by the site and Cloudflare.
Check each site's terms of use before deciding where to use it. For any site you're unsure about, add its domain to the Site blacklist; CAPTCHA recognition, Auto-check Cloudflare included, then stays off there.
Why doesn't it click in tabs I've switched away from?
By design. The point is to save a click for the person reading the page, so the tab must be in front and the checkbox visible and uncovered. Switch back to that tab and, once the box appears, it clicks then.
The check still failed after the click. What now?
Click it again yourself, or follow the instructions on the page. The extension clicks each challenge only once and doesn't keep trying, and if Cloudflare moves to a different kind of challenge, that one is yours to complete.
If one site keeps failing, work through the common causes above, or add the site to the blacklist and click by hand there.
Does it collect or upload my data?
No. Finding and clicking the checkbox happens entirely in your own browser. The extension doesn't go online or upload anything for this feature, and it doesn't need the desktop app's local recognition runtime. The switch and the Site blacklist live in the extension's settings; if Chrome sync is on, they sync to your other Chrome browsers signed in to the same Google account.
Do I have to pay for it?
No, Auto-check Cloudflare is free. You do need 77Fox for Windows installed first, because the extension is installed through the desktop app.
