I've been looking at firewall logs for my client and router software firewalls. My 3rd party firewall flags repeated outgoing TCP packets to IP 34.149.100.209 as coming from Firefox and 'Restricted', although restricted is the firewall apps syntax. When I look at the router firewall on WAN it was seeing the same IP outgoing. These packets only originate when Firefox (latest version) opens. Perhaps there's nothing to worry about or it's there to poll for those who want to select a Google search engine? Anyway, I've added a rule in the router to block the IP, although I think Google use other IPs.

There is plenty of web discussion to REMOVE restricted from Firefox but I want to make sure 'Restricted' in my case means BLOCKED, is that possible or do I misunderstand what restricted means? Thanks

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

I’m using Firefox version 134.0.2 in MacOS 15.2 with 1Password version 8.10.56 for Mac. The 1Password extension is enabled and the app is open and unlocked but each time I open a site requiring login and password I get a pop-up telling me to, “Press the 1Password icon in your browser’s toolbar to unlock.” This requires me to unlock 1Password again to enter the site’s login/password combination. Not sure if this is a Firefox or 1Password issue but it’s annoying. Any thoughts on a resolution? Thanks

Initially connects video playing to Headphones via Bluetooth then audio stops. Reloading doesn't help. But the same works perfectly on other browsers. Problem is with Firefox audio setting. The problem started only a week ago for firefox

Hello, i am wondering about the blocking of extensions on "Quarantined Domains".

Is there a list of them available to explore? Who maintains this list? Can some fishy website admin add his domain to it to block some 3rd party security addons? How can i whitelist a fishy extension on only 1 blocked site without losing the protection?

The faq articles are not really helpful for this.

I want to install a old version 52.3.0 X64 on my computer for developing web app. (the application is run on 52.3.0 X64). But I can not find the installation. Is there download center for the firefox old version?

It's not that they are not in my Firefox downloads manager, which I expected. It's that I confirmed before closing my private browsing window that they were in my Downloads folder on my C drive, and when I went back after closing the private browsing window they were gone. Under "recent files" in my file browser it showed a couple of the most recent downloads and when I tried to click to open them it said they had been moved or deleted. Entering the first couple words of the file titles in the search bar in my file browser yields absolutely nothing.

This was over 30 files or so. It will be really irritating to try to find and download all of them again. Does anyone know of any way for me to get them back???

In previous versions of Firefox (up to version 133), it was possible to automatically trigger printing of a PDF file by loading it into an iframe from a sandboxed iframe and call print. However, starting with version 134, this no longer works.

Is there any other way to automatically trigger the print dialog for a PDF file in Firefox, similar to how it can be done in Chrome/Edge (e.g., by opening the PDF in a new window and directly triggering the print dialog without additional button clicks)?
