Firefox Community Forum

I am reaching out to seek assistance with a recurring issue we are experiencing in the Mozilla Firefox browser.

Issue Description: On the user's first visit to the page, the thumbnail fails to load and displays a black screen instead of the intended image. This issue is observed specifically in Firefox, while the same functionality works seamlessly across other browsers.

Steps to Reproduce: Open our webpage in Mozilla Firefox. Ensure it is the first visit (clear cache if necessary). Observe the thumbnail image section.

Expected Behavior: The thumbnail should load and display the intended image correctly.

Actual Behavior: The thumbnail displays a black screen instead.

Troubleshooting Steps Taken: Verified server response and headers; no anomalies found. Checked CORS policies and ensured they are configured correctly. Tested in other browsers (Chrome, Edge, etc.), where the issue does not occur.

Request for Assistance: Could you please help us identify if this issue is related to:

Any specific Firefox rendering engine behavior? Known bugs or limitations in handling thumbnails or images on the first load? Additional configurations we might need to implement for Firefox compatibility?

Firefox will not load my default page (gmail inbox) when launched. It takes me instead to the google help page, specifically for cookies and cache clearing. My other installed browsers work fine with launching my google account and all its apps. Image upload below is of the page that pops up. The sign-in button does not work.
