You just introduced a new "HTTPS-Only Mode" -- as of the last version or two, it no longer allows access to an "http://" site. All such sites are blocked only by Firefox. Is there a fix?

In the Settings, the "HTTPS-Only" feature seems broken. There is an option to 'Don't enable" this feature, but that doesn't make any difference. I can get to an "http:" site using any other browser, but not with the latest Firefox.

I'm suddenly getting repeated/multiple Mozilla Firefox "Browser Alerts", "System Warnings," and "McAfee Critical Virus Alerts" that are wrong and dysfunctional. They pop up every few seconds. They contain "Remove virus now" and "quick scan" buttons, but these only take me to a bright red screen that says:

"Deceptive site ahead Firefox blocked this page because it may trick you into doing something dangerous like installing software or revealing personal information like passwords or credit cards."

These come even though I haven't tried to access any "deceptive sites." I have to x all of them out to clear my screen.

There's obviously a defect in your warning system. How do I stop this?

I clicked on a link in a forum site - pentaxforums.com - that should have pulled up image from a private web site but I think the url has been hijacked, the image didn't appear and instead the browser started pinging alerts. I have run avast anti virus and malwarebytes, these found suspicous malware (trojan, key clone) and rebooted, but these alerts still keep appearing, however I am wondering of the browser alert system itself has been compromised. See screenshots. if I click on one it seems to be trying to go to a suspicious url. any advice appreciated Marcus Brown

What happened to Firefox's permission's page? There's so few options now. I'm being harassed by websites to give them permission that should be blocked across the entire browser. I'm autistic and sensitive to popups/interruptions/distractions. So most permissions I simply had off for everything, because I don't want to be asked anything. I don't want to confirm anything. I don't want any popup of any type. So I turned everything off and it was good. (except blocking cookies of course)

But now sites are asking me again and there's no way to blanket turn off everything. I see I can press "Ctrl+i" to bring up specific permissions for that site, but that's not good enough. I specifically need permissions blocked for sites I've never visited. Needing to visit the site first completely defeats the purpose.

The permissions listed in the settings isn't all of them. How do I turn off ALL permissions for ALL sites. I can turn on specific permissions when I want them. Essentially, how do I recreate functionality that used to exist but was removed from us for whatever reason.

Also, it's a huge security hole! I'm a senior full stack developer. Asking permissions for a user is a great way to fingerprint them. If I accidentally hit "yes" to a few key permissions, I can be fingerprinted. Another reason I should be able to blanket ban these permissions. I just want my browser to be a browser. These permissions do nothing for me but make the experience worse.

woke up after doozing watching a yt video and on my pc i couldn't oppen firefox and it kept crashing so i just booted my pc again

After that i could open firefox but it had a yellow simbol on the three dot setting sections that stated "new tab has downloaded a new component"

i searched online and they said it could be an hijacker i refreshed firefox and run an anlysis with the base windows antivirus

the antivirus say's i'm clean but i still kinda unsure:

  was it really an infection? i ask myself if it could be just a firefox bug i checked extention before refreshing and the only one was 7tv and nothing else
  if it was an hijacker how can i fully know if i'm clean? what better steps can i take?

I'm getting announcements of a virus threat that purports to come from Mozilla Firefox. Usually one or all three of the attached small windows that say: 1. "Viruses Found. Antivirus notification. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 2. Attention! Click here to secure your data!. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 3. "System Warning!. Click here to remove them! via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. I have run full scans and offline scans with MS Defender, but these warnings still appear. Is this legit? I suspect these are a virus of some sort. Either way, how do I deal with this?

Was prompted to download a program to Firefox before I paid my phone bill. I did not recognize the web address or name that was shown, and the account number from which recent payment was deducted did match any accounts I hold or held in the past. I cancelled the action immediately, without downloading, but am still concerned. I found nothing on the internet about this, just got a summation chat AI response that stated the phone company had no download/extension for Firefox. Has anyone had any experience like this or could someone shed some light on this?

Today as I got to work (Windows 11 machine), I had a suspicious Firefox.exe file on my Desktop, it was not a shortcut, but exe file. I did a little investigation and research, and I noticed some difference from Program Files exe file and Firefox.exe on my Desktop:

C:\Program Files\Mozilla Firefox\firefox.exe

and Firefox.exe that appeared on Desktop

C:\Users\User\Desktop\Firefox.exe

I scanned both files in VirusTotal, and they both seems clean and legit

I uploaded both files to:

https://drive.google.com/file/d/1kALgQbfhIpHqs1pN6dmTdF71nm10LlD-/view?usp=sharing

Can somebody assure me that both files are OK, and can somebody explain to me why Firefox.exe appeared on my Desktop, and why is there difference between two files in size, Copyright info, and original filename ?

II must have been onto a dangerous site ??? but anyway I was using another browser and Firefox popped up with messages indicating a virus. As I am a retired head of IT, I closed internet and uninstalled Firefox. I then scanned my Pc with 3 different antivirus packages, My default installed is Sophos. Then there is teh standard MS , plus I installed ESET. All cleared my machine with no issues. I then re- installed Firefox, , it picked up my data and the virus message popped up again. I immediately uninstalled it again. I use REVO to uninstall, which scans for left overs, which I delete as well. Now I HAVE TO ASSUME that Revo is NOT clearing ALL FIREFOX files/data off my PC. Please advise where it is and how I can delete it completely, which is causing the messages to pop up again as soon as i install Firefox.
