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?

I did a windows security scan yesterday and it found a trojan in the Users\appdata\local\mozilla\firefox\profiles\c4h...\cache2\entries. Detected: Trojan:Script/wacatac.H!ml.The file is a containerfile. I tried removing it few times but it keeps coming back. This has made me feel uneasy even though I believe it to be a false positive. I've done 3 scans now and it always finds the same file. When I try to look for the file in the folder it's not there, so I can't upload it to virus total.

This issue seems to be getting worse as time goes on. I have to go to another browser to use Cabella's, Nextdoor, and several others. sometimes I get bad request when using a link or in the case of Cabela's I can not navigate their site. Lately I have been getting a warning of dangerous site when I hit the link in an email for all the forums that I belong to.

I love Firefox's bookmark system, other wise I would just use another browser, but I'm hoping you can correct these issues for me.

Why do I have to re-register with my banking website to remember my settings in order to not need two-factor authentication? I have selected in Preferences/settings for that website's cookies, etc, to be retained in Firefox.

So i reinstalled my graphics driver yesterday, and after that when i open a pdf on firefox it only shows blackscreen. it didnt happen on other browsers(chrome, edge)

Dear Sir/Madam,

I have recently found some sites that do not open in Firefox, however, in Chrome everyhing is fine. This was one of them: https://sciendo.com/article/10.2478/jdis-2025-0002

The other one was a login page for an Admin site - that is not suitable for testing, since it contains confidential data.

Could you please check it?

Thanks, Krisztina Kőrösi

I have looked on the web and continue to find all sorts of references on how to configure your browser to open the tabs I had open last time I closed the browser. I have the "Open previous windows and tabs" checked in the General settings....and it doesn't work! How is that? Any special thing I need to do to get it to work?
