If you've ever opened Edge and noticed that some of your favorite extensions are suddenly disabled, it can be frustrating. The most common reasons usually come down to a few key factors: browser updates, security policies, corrupted data, or even conflicts between extensions.

1. Browser Updates Can Automatically Disable Extensions

Edge is Chromium-based, and like Chrome, it automatically updates in the background. Sometimes, after an update, extensions may become incompatible temporarily — especially if the extension hasn't been updated to work with the latest version of Edge.

• You might see a message like “This extension may not work properly.”
• In some cases, Edge will disable outdated extensions completely as a security precaution.

What you can do:

• Wait a day or two for the extension developer to push out an update.
• Check the Microsoft Store page for the extension to see if there’s any notice about compatibility.
• If you're tech-savvy, you can manually check edge://extensions/ to see if there's a warning message next to the extension.

2. Group Policies or IT Admin Restrictions (Common on Work Devices)

If you're using a company or school computer, your administrator might have set policies that restrict certain extensions. This often happens silently — you won’t get a pop-up explaining it, but you’ll notice that you can’t enable certain extensions or that they keep getting disabled.

How to tell if this is happening:

• Go to edge://policy and look under “User policies” or “Device policies.”
• If you see something like “ExtensionInstallBlacklist” or “ExtensionInstallForcelist,” then extensions are being managed by policy.

Your options:

• If it’s a work device, contact your IT department.
• If it’s personal but shows policy settings, maybe you installed some management software accidentally — consider resetting Edge settings or reinstalling.

3. Corrupted Extension Data or Conflicts Between Extensions

Sometimes, an extension can crash or conflict with another one, causing Edge to disable it automatically. Or, if the extension itself has corrupted data stored locally, it might fail to load.

Signs of this issue:

• Only one or two extensions are affected.
• They worked fine before but stopped after a crash or unexpected shutdown.

Try these steps:

• Remove the problematic extension and reinstall it.
• Clear browsing data, especially cached images and files.
• Try disabling all extensions, then re-enable them one by one to find the culprit.

4. Security Features Like Windows Defender Application Guard or SmartScreen

Windows has built-in protections that sometimes block extensions from running if they’re flagged as suspicious or behave unexpectedly.

• Application Guard, for example, blocks most extensions from running in secure browsing sessions.
• SmartScreen might flag an extension if it detects unusual behavior.

To check:

• See if the extension works in a normal window but not in a protected one.
• Look at the SmartScreen settings under Windows Security to see if anything was blocked.

In most cases, extensions getting disabled in Edge isn’t permanent — it’s either a temporary compatibility issue or something related to system-level settings. Most users can fix it by updating, reinstalling, or checking for policy restrictions.

基本上就這些。
