Because it's built using web standards, Canvas runs on Windows, Mac, Linux, iOS, Android, or any other device with a modern web browser.
Canvas supports the current and first previous major releases of the following browsers:
- Chrome 78 and 79
- Firefox 71 and 72 (Extended Releases are not supported*)
- Edge 44 (Windows only)
- Edge 79
- Respondus Lockdown Browser (supporting the latest system requirements)
- Safari 12 and 13 (Macintosh only)
You should always use the most current version of your preferred browser. Your browser will notify you if there is a new version available.
Unsupported Browser Banner
Some supported browsers may still produce a banner stating Your browser does not meet the minimum requirements for Canvas. If you have upgraded your browser but you are still seeing the warning banner, try logging out of Canvas and deleting your browser cookies.
Enterprise Extended Release Browsers
Chrome and Firefox offer extended release versions for organization that manage client desktops. Chrome ESR can be kept up-to-date with the existing full version of Chrome at any time. However, Firefox ESR is only updated with every seventh major version, which causes Firefox ESR to overlap with outdated versions. The Firefox ESR webpage notes that ESR may not be supported in every web application because of this version release delay. Institutions who use Firefox ESR should consider deploying the latest release to ensure the best Canvas user experience.
* For extended release browser versions, the warning banner still applies and displays in Canvas for any browser below the minimum version requirement.
Known Browser Behaviors
Like all Canvas features, contrary behaviors relating to browsers are prioritized by our product teams, and some behaviors in the previous version may not be resolved. If a behavior exists in the previous version of the browser that does not exist in the current version, the best solution is to update to the newest browser version.
Canvas is committed to W3C's Web Accessibility Initiative. To learn about supported screen reader and browser combinations, please see the Accessibility within Canvas document.
Browser Plugins and Extensions
Some browser plugins or extensions may conflict with Canvas and affect functionality. If you experience behavior that does not allow you to view or participate in Canvas courses, please ensure you have disabled any extensions or plugins that interact directly with your web browser.
For troubleshooting, consider logging in to Canvas using an incognito or private browser window, which will provide a browser session without any prior browsing or search history, associated browser cookies, or other factors that may interfere with the browser. If you are able to view and participate in Canvas using an incognito or private browser window, the behavior you are experiencing is likely related to the browser and not Canvas.
Browser Privacy Settings
To ensure browser security, follow all browser security policies established by your institution, especially if you are using Canvas on a computer provided by your institution.
When displaying content, Canvas defaults to the preference set by a specific browser. Some browsers may occasionally make modifications to privacy settings to protect users from possible insecure content. Insecure content is identified with the prefix http:// in the URL and can create mixed content in your Canvas Page. Secured content is identified with the https:// prefix in the URL. For the best user experience, content should be secure to avoid browser conflicts.
- If you are a Canvas admin, insecure content may be caused by hosting an insecure JS/CSS file outside of Canvas. If custom uploads are supported for your account, you can host your file in the Canvas Theme Editor, which will resolve any browser conflicts.
- If you are a Canvas instructor who embeds Canvas lessons inside your course, you can prevent browser issues with mixed content using secured Canvas Guides URLs.
Known Browser Behaviors
Chrome and Firefox use HTML5 to display website content, promoting a faster, more secure browsing experience. HTML5 audio and video is currently not supported in Microsoft and Safari browsers, and audio and video must still be used via Flash.
For best performance in Canvas, course content should be designed to support HTML5. Any affected content in Microsoft and Safari browsers can still be accessed by manually allowing permission for flash content in the browser.
In browsers such as Safari, insecure content will never be displayed in the browser.
However, in Chrome and Firefox, you have the option to view insecure content. Please be aware of possible restrictions and view insecure content with caution.
The following are known issues in Chrome and Firefox that may block or create mixed content within Canvas.
Google Chrome verifies that the website content you view is transmitted securely. If you visit a page in your Canvas course that is linked to insecure content, Chrome will display a shield icon  in the browser address bar.
You can choose to override the security restriction and display the content anyway by clicking the shield icon and then clicking the Load unsafe script button .
Chrome Media Permissions
Chrome has its own media permission within the browser. To use your computer camera and microphone within any Canvas feature, you will have to approve two permissions:
- Allow access to Canvas via the Adobe Flash Player Settings . This prompt appears in the center of the video and audio pop-up windows, or the center of the browser if you are accessing Conversations.
- Allow access to Canvas via Chrome's media permission settings . This prompt appears just below the address bar. Click the Allow button.
Firefox verifies that the website content you view is transmitted securely. If you visit a page in your Canvas course that is linked to insecure content, Firefox will display a lock with a warning icon in the browser address bar .
You can choose to override the security restriction and display the content anyway by clicking the lock with a warning icon, clicking the arrow to expand your options , and selecting the Disable protection for now button .
