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."

the size of the offered tabs became too huge in the address bar. Something happened in my browser and it reset all the settings. How can I reduce their size? They take up half of the browser screen

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.

Firefox, like most browsers, is full of jargon and terms which are never defined. So, for a new user, what should be simple become complicated. Developers obviously thought that everybody understands, but it is not true. It would be helpful if there was a term definition for each term and symbol used. I find my self in a kind of rabbit hole when trying to do things, and even when I ask for help, there is no term definition help.
