Though i did not log into any sites recentl, the status for all my saved logins indicate they were last used either yesterday or the day before. How can this be? Have they been compromised?

In the SharePoint library Setting is the desktop App defined to open M365-files. Chrome, Edge and Opera, open the files in the desktop App. Not so Mozilla Firefox: with this browser, the files are opened in a Tab, instead of the desktop App. Why is that? How can I change this behaviour?

It did'nt change with marking "Ask, how files are opened or saved With kind regards, Christian

Hi, everyone. I hope you will be doing good. As we have a website about delusion calculator which is properly working in other browsers. While checking it in the firefox I found that the website is so lazy and break down while during the loading time. Could anyone here can guide me about this issue?

When uninstalling Firefox developer edition my anti virus firewall popped this message:

"Firefox Developer Edition Helper does not have a valid digital signature"

Filename: Un_A.exe

Does anyone know anything about this?

Hello and great work so far Firefox team!

Currently, Firefox can be used in Windows from the command line to open any URL (start firefox www.google.com). Since any browser is expected to have Internet access to any website or IP address, this is a real security concern in case of default deny security for firewall outbound traffic.

Here is a hacker scenario: The PC has a list of whitelist applications allowed to connect to the Internet. This prevents lots of malware from connecting to their remote servers. However, malware can bypass that by listening on localhost and requesting Firefox to open the remote server. This way the malware sends and receives data with the server using Firefox after requesting an URL with the malware local port specified as query parameter.

This can be avoided with a special about:config option that completely disables command line processing. I don't know if that's entirely possible, but preventing Firefox to start URLs from command line or explicitly requesting Internet access for static HTML files should be enough.

Note: I use NoScript and that helps in this case, but it is not a bullet proof solution. It may be possible that one of the CDN I have allowed gets hacked with malicious JavaScript. If the malware is already on the PC, it can connect to the remote server using the hacked CDN that is allowed in NoScript. This is a two piece attack, but I still think that using Firefox to access to random URL from command line is dangerous and should have an option to be turned off.

I disabled all extensions today to troubleshoot a website and all of my Firefox container data is GONE!

Luckily, I have a second computer with Firefox that was synced earlier today before I did this.

I have put that computer #2 into airplane mode and have not opened Firefox in fear that a new sync will overwrite the data.

So far, I have saved "containers json" and "cookies sqlite" from computer #2 profile folder

Then, I backed up "containers json" and "cookies sqlite" from computer #1 profile folder (this is the computer I'm using now with the broken containers)

I have placed "containers json" and "cookies sqlite" from computer #2 and overwritten them on computer #1

The container names are back, and some of the containers remember the site logins, but some don't, and none of the websites will open in the specifically chosen containers from before.

Is there a way to restore the sites that were logged in and which sites auto-open with the specific container?

Thank you in advance

I wish to add a new PC to devices I am currently syncing (a "legacy" PC, a laptop, my iPhone). I can confirm from the legacy my correct password and can log in using it. I have installed the up-to-date Firefox on the new PC. When I attempt to log in to Firefox/sync on the new machine, it will not recognize the confirmed password. FYI, this is a new password created Aug 23. The new machine runs Win 11, the old Win 10.

Good morning I was using firefox on windows 8.1 I moved to Windows 10 and after logging in to my Firefox account, my bookmarks and passwords from the Firefox sync service were not restored.

please help,

(This question should be directed at Google too.) I was watching a video the other day on Archive.org and the name Kevin Farley was mentioned; spoken, no subtitles/annotations. I paused watching the video and did a Google search on my Firefox. I typed in the word "Kevin" and the first suggestion was Kevin Farley. How is this possible? That can't be the first suggestion unless the video player on Archive.org and Google are communicating with each other. Anyone can think of several Kevins who are actors such as Kevin Farley, but more well-known than this brother of Chris Farley who, for that matter, was very well known. I don't believe that there are hidden microphones inside my computer or anything like that, but – in all seriousness: how the heck does this thing work? Is Google listening to me? And if it is, that means Firefox is allowing it to listen to the stream of audio through my sound card. (At least the line out. Maybe I should try and see whether the line in and mic in are doing the same and play a vocal sample from an external source/device saying "Kevin Farley" or speaking those words through a plugged-in microphone and see how Google responds to that.)

On Firefox's settings (privacy) I have not allowed any site to use my microphone, speakers or camera. On my sound device's settings videos, music and everything I do audiowise is going through "microphone", although I'm plugged in on the rear panel of my PC only to line in and line out i.e. when I'm playing music on WinAmp, it shows that a signal is going through the microphone as it is going through my output. (If I try to disable the microphone, then I can't capture any signal i.e. I'm unable to record sound off a video clip or from my external audio gadgets.)

Not quite sure whether this is a problem with Google, Mozilla or my PC's sound card or with all of them, but it still is an interesting issue.

Why, why when being prompted to update, updating fails and I abort (only real choice) is the previous version of Firefox removed? This happens all the time and every time I have to do a complete new install and redefine all my Quick Access menu items. If this happens one more time, I will use someone else's PDF reader. Updating should not be that hard. I have administrator privilege's so why does your software updates fail?

Firefox shows a website as "most frequent" though I have not used the website since many months. Additionally, the history shows a visit for this website from this year that I did not do and on the other hand there are a lot of visits for the same website from last year that I remember but that are not in the history. What can have caused this and how can I prevent it?

I use a website from the USPS and have for 20 years. Now, about a month ago, it will not load my sign-in page. https://reg.usps.com/entreg/LoginBCGAction_input?app=EadminAPP&appURL=https://gateway.usps.com/eAdmin/view/signin/loginCheck This the site I need to run my business. Why, all of a sudden, it will not open. There is no error message. It just keeps trying to load the page. Firefox is my browser of choice by a lot, but if I can't do my work, I can't use it.

I have a couple of computers that are not allowed to have full access to the internet.

I've added the following URLs to the whitelist on my firewall:

aus5.mozilla.org and mozilla.org.

So far the only thing that has happened is the browser is able to tell that a new versions available but it's stuck downloading the update with zero progress.

I've seen some five or seven year old posts that claim I have to have the following URLs whitelisted:

aus.mozilla.org aus2.mozilla.org aus5.mozilla.org ftp.mozilla.org archive.mozilla.org download.cdn.mozilla.net mozilla.org mozilla.net mozilla.com

But since these are from a 5+ year old post I would like to know if these are still valid? And if not then what URLs are valid?

Every time I login using my smart card I get this alert message

"Please authenticate to the token “ActivID ActivClient 0”. How to do so depends on the token (for example, using a fingerprint reader or entering a code with a keypad)."

I don't need to see this message every time I log in using a smart card. Is there away way to turn of the annoying unnecessary alert?

Hello,

I rebooted my Mac and all of sudden I can't get to any websites using Firefox. I'm using Chrome now so I can work. However, my preference is to use FF. Can someone please help me?

Thanks, -Jerome

when playing a video on youtube a mute button should appear when hovering over the tab when language is hebrew, this sign appears always, being on top of the website icon

On my iMac, running Ventura 13.5.2, my Firefox (primary) browser, running 117.0.1, all of a sudden began running way beyond slow; it appeared to do so -to some extent- also with Chrome as well, but Safari appeared to press through the problem and has taken the primary spot until I can figure out what has/is happened/happening?

I have closed-out each (numerous times), and performed reboots of all (apps and computer), only with what appears to be worsening performance. Similarly, I have run anti virus, cleanup, and non-essential file removal all without any positive results?

Ultimately, when I open Firefox on the iMac, I am looking at the opening (blank)Tab, and when I request any search, it just sits there...

Because the program appears to be operating correctly on the MacPro13 (this computer), the problem obviously exists on the main (iMac) computer but I cannot figure out exactly what is causing it, and how to eliminate it?

If I completely remove it from the iMac's HD, will downloading a new copy remove all saved tabs, settings, etc. (basically, starting anew)?

IM ANGRY I WROTE OUT MY QUESTION AND LONG POST I TRY TO HELP BY SHARING DATA IT SAYS TRY MANUAL INPUT I CLICK THAT THEN IT TAKES ME TO A NEW TAB AND COMPLETELY DELETES MY QUESTION!!!! dONT CLICK LINK AFTER SHARE DATA!!!
