Firefox Support Forum

I've been unable to complete the installation of the latest version of the Firefox browser for Windows 10 for several weeks because my Bitdefender online protection repeatedly blocks the connection to incoming.telemetry.mozilla.org saying: "firefox.exe attempted to establish a connection relying on an unmatching security certificate to incoming.telemetry.mozilla.org. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one."

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

Bonjour,

Depuis plusieurs semaines, il m'est impossible de télécharger des PDF depuis firefox. J'ai essayé de faire une réparation, mais désormais j'ai également perdu mes extensions et lorsque je veux les réinstaller, on m'affiche : "Échec du téléchargement. Veuillez vérifier votre connexion." (par exemple pour ublockorigin)

Merci d'avance pour vos réponses, Cordialement Selma

greetings, I had trouble with firefox crashing, so i uninstalled it and reinstalled it and now I have lost all my passwords and bookmarks from the previous installation. I have tried to fix it, but I am completely computer illiterate. Please help. I am unable to do this with directions found in my search. I need someone to do it FOR me. Please help.
