Browser feature support changed after an update?
See why a browser update can change feature support, how to check your version, engine, permissions and codecs, and which fixes to try next.
A feature worked yesterday, but after a browser update a website says it is unavailable, a video will not play, or a device permission seems to have disappeared. An update can change what the browser supports, but the cause may also be a setting, an extension, or a website using a different browser capability.
Check what the browser reports before reinstalling anything. TooLab’s Browser Info shows your browser version and engine, along with permissions, privacy settings, codecs, and supported features.
Check what changed
- Open the Browser Info tool in the browser where the problem occurs.
- Note the browser version and engine. The engine is the underlying software that processes web pages. If you have a saved report or notes from before the update, compare those details.
- Look at the permissions, privacy, codecs, and supported features reported by the tool. Find the specific feature or media format the website says is missing.
- Reload the website and repeat the action that failed. If it still fails, open the same page in another up-to-date browser, if available, and compare the result.
A single missing feature does not mean the update damaged your computer. The comparison helps narrow down whether the change is in the browser, its settings, or the website.
What the result means
The browser version or engine is different
The update may have changed the code that handles web features. Browsers can add support, change how a feature works, or remove outdated support. A website that relies on an older behavior may need an update of its own. If the feature works in another current browser but not this one, the problem is more likely related to browser compatibility or settings than to the device.
A permission is blocked or unavailable
A feature that uses a camera, microphone, or another protected capability may need permission from both the browser and the operating system. A browser update, profile change, or privacy setting can affect what a page is allowed to request. The browser report can help you spot a permission issue, but it cannot make the operating system grant access.
A codec or supported feature is missing
A codec is software used to decode or encode audio and video. If a format is no longer listed as supported, the browser may not be able to play it in that version or on that device. The website might offer another format, or it might be sending a format that this browser cannot use. A codec result does not by itself show that your speakers, camera, or other hardware is broken.
The report looks normal, but the website still fails
The browser may support the feature while the page is blocked by an extension, a managed setting, a privacy mode, or an error in the website. A browser feature report describes what the browser exposes in that session. It does not guarantee that every website has implemented the feature correctly.
How to fix it
- Reload the page and restart the browser. A page that was already open during an update can keep using old code. Close and reopen the browser, then load the website again.
- Check the site’s permission. Use the site controls beside the address bar to review permissions for that page. If it needs the camera or microphone, allow access and reload. Every tool or website using a camera or microphone must ask for permission first.
- Check operating system privacy access. On Windows 11, open Settings › Privacy & security › Camera or Settings › Privacy & security › Microphone, as needed. Check device access and access for desktop apps. On macOS, open System Settings › Privacy & Security › Camera or System Settings › Privacy & Security › Microphone, then allow access for your browser if it is listed.
- Test without extensions or private browsing. An extension or a stricter privacy profile can block a feature or change what a website can detect. Try a normal browser window with extensions temporarily disabled. If that works, turn extensions back on one at a time to find the cause.
- Check for another browser update. Open the browser’s About page and let it check for updates. Restart when it asks. Updates may be released in stages, so the version number can differ between devices for a short time.
- Ask your organization about managed settings. A work or school browser may have policies that disable features, even after an update. If settings are locked or revert after you change them, contact the person who manages the device.
Why updates can change support
Browser updates do more than add visible features. They can change the browser engine, security rules, permission behavior, and the codecs included with the browser. Some web features also depend on the operating system, hardware, or a secure connection. That is why two computers with the same browser version can report different support.
Some changes roll out gradually or depend on settings, so a feature can appear on one device before another. Privacy protections can also reduce the details a website can access. If a feature disappeared immediately after an update, note the browser version, engine, and feature name before contacting the website’s support team. Browser Info shows the current state, but it cannot reconstruct what the browser reported before the update unless you saved that earlier information.
