I am using Firefox for Android. I normally use ChatGPT in Firefox instead of the Android ChatGPT app.

I found a reproducible issue with chatgpt.com and the Firefox setting “Open links in apps”.

Steps to reproduce:

1. Install the official ChatGPT Android app. 2. Open Firefox for Android. 3. Go to Settings > Open links in apps. 4. Set it to “Never”. 5. Open https://chatgpt.com.

Actual result: The website connects, but the page content is blank.

6. Change “Open links in apps” to “Ask before opening”. 7. Open https://chatgpt.com again. 8. When Firefox asks whether to open the external ChatGPT app, tap “Cancel”.

Actual result: The ChatGPT website loads normally inside Firefox.

Then I uninstalled the ChatGPT Android app.

After uninstalling the app, Firefox no longer shows the external-app prompt. However, chatgpt.com becomes a blank page again, regardless of whether “Open links in apps” is set to “Never” or “Ask before opening”.

Expected result: If “Open links in apps” is set to “Never”, or if I tap “Cancel” on the external-app prompt, chatgpt.com should load normally in Firefox.

This looks like a Firefox for Android compatibility issue with Android App Links / external app handling for chatgpt.com. It may also involve the website fallback behavior, but the blank page seems to depend on Firefox’s external-link setting.
