Why is my bootstrap not working?

Is your Bootstrap not working in Firefox? Here are some common reasons why:

  • Unsupported bootstrap version – This could be because you’re using an old version of Bootstrap, for example, or because there is no bootstrap browser support because you’re using an outdated version.
  • Corrupted extensions – Check for any browser extensions or plugins that might be interfering with Bootstrap’s CSS or JavaScript files. If possible, disable these extensions and try again.
  • Invalid CSS code – Bootstrap uses a lot of CSS classes to style its components. If you’ve customized the CSS in any way, it may not work.

Do all browsers support bootstrap? Bootstrap works on all major browsers, including Firefox, Safari, Chrome, Opera, and Microsoft Edge.

However, some features may not work or behave as expected on older browsers due to a lack of support for CSS features or JavaScript APIs used by Bootstrap’s JavaScript plugins.

Quick Tip:

In case you need an easier solution to fix Bootstrap on your browser, you may consider changing your browser.

Opera is a practical workaround because it supports the Bootstrap framework and helps you develop good-looking websites or web programs.
