220-1102 Practice Question: That their browser crashes every time they visit…
A user reports that their browser crashes every time they visit a particular website. Other websites work fine. The technician tries the same website on another computer and it works normally. What is the most likely cause on the user's computer?
⚠ Common exam trap
CompTIA often tests the principle of isolation—candidates mistakenly attribute a single-site issue to network-wide or driver problems, but the key is that the problem follows the user's browser configuration, not the network or hardware.

Correct answer & explanation
✓
A browser extension is incompatible with that website.
The issue is isolated to a single website on one computer, and the same website works on another computer. This rules out network-wide or server-side problems. Browser extensions can inject scripts, modify headers, or block resources that a specific website requires, causing crashes. Disabling extensions or testing in incognito mode (which typically disables extensions) can confirm this.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The website has been blacklisted by the company's firewall.
Why it's wrong here
If a company's firewall blacklisted a website, access to that site would be denied at the network perimeter for all users on the corporate network. This would typically manifest as a "connection refused" or "site cannot be reached" error message, preventing the browser from even attempting to render the page content. It would not cause a browser crash specifically on one user's machine while others can access it, as the block occurs before the browser processes the site's code.
- ✓
A browser extension is incompatible with that website.
Why this is correct
Browser extensions inject their own code, scripts, or styles into web pages, modifying the browser's behavior or the page's content. An incompatibility arises when an extension's code conflicts with the specific JavaScript, CSS, or HTML structure of a particular website, leading to unexpected errors or memory access violations within the browser process. This conflict can destabilize the browser, causing it to freeze or crash when attempting to render or interact with the problematic site, while other sites remain unaffected.
- ✗
The user's network adapter driver is outdated.
Why it's wrong here
An outdated or corrupted network adapter driver primarily affects the operating system's ability to establish and maintain network connections at a fundamental level. Such an issue would likely manifest as intermittent connectivity problems, slow performance across all network-dependent applications, or a complete inability to access any websites. It is highly improbable that an outdated network driver would selectively cause a browser crash only when visiting a single, specific website while all other sites function normally.
- ✗
The website is using a newer version of TLS that the browser doesn't support.
Why it's wrong here
If a website is using a version of Transport Layer Security (TLS) that the user's browser does not support, the TLS handshake process would fail during the initial secure connection establishment. This failure would result in a clear connection error message, such as "secure connection failed" or "ERR_SSL_VERSION_OR_CIPHER_MISMATCH," preventing the site from loading. The browser is designed to gracefully handle such protocol mismatches by displaying an error, rather than crashing due to an unsupported TLS version.
