Malicious Software update on 11/12/25 is causing problems

dgr308 20

Ever since a malicious software update on 11/12, I have been unable to see flight details on Delta.com. On the home page, I click on "My Trips" and the list shows up. However, when I click on "View Flight Details", I get nothing but a blank screen. I have reported this via Feedback several times but have not seen a fix or heard back. This happens on 2 separate computers using Microsoft Edge. I have no problems seeing flight details using Chrome. Is anyone having similar problems with Delta or any other website? Also, I do not see a way to "undo" that particular update.

Hello,
Thanks for sharing the details. Based on the symptoms you described, the Delta “My Trips → View Flight Details” page showing only a blank screen in Microsoft Edge after the 11/12/25 update, the issue is likely caused by one of the following:

Outdated Edge Version
- Update Edge via edge://settings/help Edge Release Notes
(Note: Even if the update is recent, ensure you’re on the latest stable build.)
Extensions Conflict
- Test the page in InPrivate mode (Ctrl+Shift+N).
- If it works, disable all extensions, then re‑enable them one by one Browse InPrivate
Include Error Collection Here:
- While on Delta.com, press F12 and select the Network tab.
- Click Clear to start fresh.
- Reproduce the issue (click “My Trips → View Flight Details”).
- Look for red or failed requests in the list.
- Save a screenshot or copy details for each failed request:
  - Status code (e.g., 403, 404, 503)
  - Request URL
Tracking Prevention / Blocked Third‑Party Cookies
- Set Tracking Prevention to Balanced.
- Allow cookies for delta.com. Tracking Prevention
Hardware Acceleration Rendering Issue
- Go to edge://settings/system.
- Toggle off “Use hardware acceleration when available.”
- Restart Edge and retry.

If you can share the exact error code or a screenshot of the message from Delta, I can help narrow down the root cause more accurately.

Hello @dgr308 ,

To help identify why the flight details page shows a blank screen, please collect diagnostic information:

Steps to collect error details:

On Delta.com, press F12 to open Developer Tools

Click the Network tab

Click "My Trips" > "View Flight Details" (reproduce the blank screen)

In the Network tab, look for API requests related to flight details (usually contain "trip", "flight", or "reservation" in the name)

Click on that request

Click the Response tab on the right panel

Take a screenshot of the Response content

Please share:

Screenshot of the Network tab showing the request

Screenshot of the Response tab content

This will show whether the API is returning an error, being blocked, or returning unexpected data that Edge cannot render.

Thanks!

Thanks. I can open the developer tools and I see the network tab. But, I'm not seeing "API Requests". I looked at "More Filters" and saw an item that said "Blocked Requests" and I clicked on that and got the items shown in the attached screenshot. At the bottom of the screen there are two tabs - Console and Issue. Both are showing error messages (some say blocked by client") but I'm not able to expand on them to get a full list. Does any of this help? Thanks again - your help is greatly appreciated!

Hello @dgr308 ,

Sorry but I don't see any your screenshot if your screenshot have any data sensitive or personal information maybe system remove it. However, I have another solutions for you to try based on the issue you're facing with Delta.com in Edge with Strict tracking prevention enabled.

Let's try the quickest solution first:

While you're on Delta.com, look at the address bar and click the lock icon (or shield icon). You should see an option for "Tracking prevention for this site." Click it and turn it Off for this site, then refresh the page.

If that doesn't work, we can try adjusting the global tracking prevention setting:

Type edge://settings/privacy in the address bar

Under "Tracking prevention," switch from "Strict" to "Balanced"

Restart Edge and try Delta.com again

About those Console errors:

I noticed you mentioned error messages at the bottom. To see them more clearly, click the "Console" tab in that bottom panel, then take a screenshot. That'll show us exactly which resources are being blocked and confirm we're on the right track.

Once you allow Delta.com or switch to Balanced mode, those blocked requests should go through and your flight details should display normally.

I hope this helps! Let me know how it goes or if you need further assistance. If my answer useful, please mark it as accepted. Thanks for working through this with me!

Thank you so much!!! I tried everything you said and also turned off Windows Defender Firewall (it's been turned back on). The thing that worked: changing Tracking Prevention from Strict to Balanced! Full access to Delta is back. Can't tell you how much your help is appreciated. Have a wonderful day.

It seems that you are experiencing issues with viewing flight details on Delta.com using Microsoft Edge, while it works fine in Chrome. This could be related to the recent updates in Microsoft Edge, which may have introduced compatibility issues with certain websites.

Here are a few troubleshooting steps you can try:

Clear Cache and Cookies: Sometimes, cached data can cause display issues. Go to Edge settings and clear your browsing data.
Disable Extensions: Some browser extensions can interfere with website functionality. Try disabling them temporarily to see if that resolves the issue.
Update Edge: Ensure that you are using the latest version of Microsoft Edge. Updates often include fixes for bugs and compatibility issues.
Check for Security Settings: Sometimes, security settings can block certain content. Check your Edge security settings to see if anything might be causing the issue.
Try InPrivate Browsing: Open an InPrivate window in Edge and try accessing Delta.com to see if the issue persists. This mode disables extensions and uses default settings.

If these steps do not resolve the issue, it may be beneficial to report the problem to Microsoft Edge support for further assistance.
