Firefox Community Forum

I am running an iMac that is about eight years old.This afternoon my Firefox browser was taken over by a "warning" from "MacOS security center" that I should go to THEIR macOS support site to get my system unfrozen. The number they give is 1-877-xxx-xxxx. I cannot get this intruder to go away, even by restarting the computer.

I always use Firefox Private Window when I go on the Internet. Today, while I was on Fidelity.com, I was suddenly logged out. When I tried to go back to Fidelity.com using Firefox/Private Window, a dialog box on Microsoft Edge appeared asking me to: "Choice: #1 Do you want to make Firefox to be your default" "Choice: #2 Not Now". Which ever I choice I choose, Microsoft Edge will appear with the two above choices. This has been happening repeatedly for several minutes now, so I tried to reach Firefox Support.

My main problem is I cannot access Firefox / Private Window anymore since I was suddenly logged out of Fidelity.com.

Would you please fix this problem. Also, I already selected Firefox to be my default browser long time ago. Why am I being this question every time I go on the internet using Firefox?

ich habe vergessen, meinen Mozilla account zu bestätigen. Auf meinem iPhone funktioniert der VPN Tunnel, auf weitere Geräte kann ich ihn nicht übertragen. Ich habe vor einer Woche mein Abo über den Apple Store verlängert. Kann ich die Bestätigungsmail erneut erhalten

I can no longer press the print button after a bank transaction wanting a print saved copy the Bank tells me I MUST upgrade my Mozzilla / Firefox programs... I do that every time YOU tell me and I press the button .. SO what else do I have to do>> As you may guess .. need some baby step help Please! Regards Jeanette

I keep getting messages from Firefox to confirm account with the code. Looks like somebody keeps trying create an account with my e-mail address. I never hit confirm and I just delete the message. I keep changing my password.

Hi hi, I just did a complete reset to factory settings of my laptop (MSI), and a wipe of my hard drives too. After reinstalling Firefox (literally the first thing I did after setting up windows), it runs more slowly than before the reset (even for a basic search on Google/Duckduckgo). I am also unable to load any pages under the domain discussions.unity.com : the page loads forever, it's impossible to click on anything (even the hovering styles don't work), and I get a banner at the top of the screen that says "This page is slowing down Firefox. To speed up your browser, stop this page.". Also the memory usage for this page skyrockets (gone up to 4000MB??). I've disabled the 2 extensions I have (Dark Reader and Adblock Plus), restarted Firefox, restarted the computer, cleared the cache, even turned off the mozilla syncing, nothing worked. Any idea on what could be happening here? It's the first time in using Firefox for over 15 years that I've seen this happened.

Thank you for your time and attention <3
