How do i keep my work computer browser seperate from my home browser account???

Somehow out of the blue my home firefox account became my work firefox account? All my work shortcuts or bookmarks appeared at my home but i dont want them.

Hello guys, as in title - I use custom NextDNS set of rules on DNS-over-HTTPS. As of today, Firefox can't connect to the provider. AFAIK Troubleshoot Mode is also affected. The other devices using NextDNS on my network work just fine and when I set the DNS to work system-wide as a kind of workaround, I don't get an issue. Same when I use other DNS-over-HTTPS options in the Firefox Preferences. Yesterday the problem didn't occur and I haven't performed any updates since yesterday - both Firefox and NetworkManager seem to be up to date.

Additional info: OS: EndeavourOS (Arch Linux) Firefox version: 129.0.2

If any other info is needed, I'll be happy to provide it to you.

So, it happened again today. Saw their commercial on TV today and went to legacybox.com (NEVER BEEN THERE BEFORE; they transfer VHS tapes, and other stuff, to digital) and got an email from them after closing the browser tab and leaving their website. While I didn't open the email, their email Subject/title was "Thanks for stopping by...".

All I did was look around their website for a few minutes AND DID NOT GIVE THEM MY EMAIL ADDRESS!

This is EXTREMELY DISTURBING!

PLEASE, If anyone here has the Video DownloadHelper extension installed in Firefox AND their Companion App (it costs ~$28, I think.. so don't bother if you don't have it). And make sure you've updated to a recent version, WHERE THEY HAVE YOUR EMAIL/Licens# IN THE SETTINGS (L click on the VDH icon, click on the gear icon, and at the bottom of the menu, click on "More settings....". If your email is there, PLEASE GO TO Legacybox.com AND SEE IF THIS SITE SENDS YOU AN EMAIL as this may help to confirm if Firefox is leaking emails thru that app. Thanks!

Are my passwords secure if I just use FireFox right out of the box (just downloaded) without logging into my FireFox/Mozilla account? Firewall is on.

Or must I be logged in for best security?

I use a 2024 MacBook Air M3. FF version 129.0.2 macOS Sonoma 14.6.1

Thanks, Tom

When I go to History and then Clear Recent History with History and Temporary File checked and the hit Clear nothing happens.

I found that I can delete the histories one by one with the Delete key.

Occasionally, after visiting a legit/non-questionable/non-sleazy website that I’ve never been to before, I'll get an email from that site immediately, after leaving the site. These have been just plain websites that are selling a product (roofing, windows, etc.). HOW ARE THEY GETTING MY EMAIL ADDRESS???!!! So, far this only happens when using Firefox.

Are they getting it thru Firefox AFTER I’ve used my email address (as a username) after having logged out of a previously visited website? (And yes, I know I can just delete my history after leaving those logged in websites, but I shouldn’t have to... However, when/if I do log into a financial institution, I ALWAYS CLOSE that browser window after logging out.)

OR, are they possibly getting my email address thru a Firefox extension, “Video DownloadHelper” (installed thru Firefox), where I CAN SEE my email address (and license#) listed in the extension’s settings for its Companion App? And, if it IS this extension, how can I get Mozilla to block that info from sites I visited??!!! (other than uninstalling the extension)

Using Firefox, v129.0.2, 64-bit. and Windows 10 Pro, 22H2, build 19045.4780 (although Firefox shows: "Windows_NT 10.0 19045"). Also, auto-fill is unchecked in Firefox settings and I NEVER save usernames/passwords in of thru my browser.

Why on God's green Earth is there a widget by default that has access to my location? I understand that it's just for weather but it is seriously unacceptable that a browser that claims to care so much about privacy plasters my location on my screen for all to see when I open a new tab. Seriously, who thought this was a good idea and how can I turn it off?

Firefox releases email addresses and our data to third parties!

I installed the Arc browser and Arc offered to load my bookmarks from mozilla. Out of curiosity, I let it, and it loaded my bookmarks and folders smoothly. Arc didn't navigate Firefox to the login page, so Firefox released my information without asking me.

What probably happened in the background was that the Arc browser told Firefox which email address it was requesting data from, and Firefox handed over the data to it "on notice". Firefox was not even convinced that the real owner of the email address asked the Arc browser to synchronize the folders.

Is it the famous Firefox reliability?

I'm trying to use a security key for my Vanguard site. I've tried with Firefox, Microsoft Edge, and Chrome. I can get to almost the end but get stopped-- I can't get no father to "connect and activate." I get a message saying--"Vanguard is requesting extended information about your security key which may affect your privacy. Firefox can anonymize this for you but the website might decline this key. If declined try again." I talked to Vanguard for help but they didn't know how to help. The key is uTrust FIDO2 NFC. USB-A NFC Certified Security Key. I believe the problem may be that this key will link all my accounts in Firefox ( and will also link if I use any other browser.)

I got the following from the internet: When it says authenticators it means Security Key.

Using an authenticator for one account is safe, but allowing a website to ask for extended information for multiple accounts using the same authenticator can permit that website to identify a link between those accounts. If you are concerned about having accounts linked together in this way, you should either deny extended information when prompted, or use different authenticators for the different accounts. This linkability is based on the authenticators, and not on your browser. If you use the same authenticator with different browsers, websites can still identify a link between multiple accounts. Can this be solved? Thanks joek90ros@aol.com

I use both Firefox and DuckDuckGo. I also have NordVPN. Recently, I have been getting warnings through NordVPN that both Firefox and DuckDuckGo represent vulnerability risks. I have been using all three programs for some time now. This warning from NordVPN is something new. Is there a vulnerability risk or is there some in compatibility between new versions of these software packages?

I am using Windows 11 on a Microsoft Surface Pro 9.

Thanks for your help.

Hi again,

so, in my other question I was reminded about Browserleaks and while I was there testing TLS I also tested Canvas and it said 100% unique which I was surprised because I have the Enhance Protection in FF in "Custom" with both fingerprinting options selected and in "in all windows", plus CanvasBlocker.

100% unique is not good, right? That's what I thought at first. But then I remembered, CanvasBlocker rotates settings all the time, so even if my fingerprint is 100% unique it's also changing all the time which means "they" can't identify me (supposedly). Then I also thought "actually it might be better than not 100% unique because in that case I might have more issues with websites thinking that it's someone else trying to access my account". But then I thought "although if it's 100% unique changing all the time it's also like if it was a different person".

I deactivated CanvasBlocker and tested again and it was also 100% unique. Then I reactivated CanvasBlocker and I deactivated FF's anti-fingerprint. Again 100% unique. In other words, I don't see a way to see what is the difference between using CanvasBlocker on top of the native FF anti-fingerprint. That's where you can help :)

So, questions.

1) can you tell me what exactly does FF block about fingerprinting? And, does it rotate settings like CanvasBlocker so that this "100% unique" is not actually a real issue because it's different every time? Or is it a bad kind of 100% unique in that case?

2) what would create less issues of websites thinking that I am not me? A rotating 100% unique, or a not 100% unique (in which case, how to I achieve that, considering that neither CanvasBlocker nor FF's anti-fingerprint nor both together can do that?).

Would you say that having a VPN with own DNS which block tracking on a domain level, plus AdGuard with all possible filters, plus FF's Enhanced Protection in "Custom" with all at max, plus CanvasBlocker, is a good combo? Or what could I improve to reach a good balance of not being tracked/fingerprinted, not being blocked "because I am not me", reasonably light resources usage, and reasonable browsing speeds?

I used uBlock Origin previously because it's lighter on resources and it triggers my laptop's fans much less than AdGuard but it doesn't block (not even with element picker) some annoying things of websites that I visit often. In case you wanted to recommend that :)

Thanks!

Hi!

First of all, mods, if I chose the wrong category and this had to go in "customize settings and preferences" feel free to move it :)

So, for several reasons I decided to completely disable SSL and the old TLS 1.0 and 1.1. I still didn't decide if TLS 1.2 is still important or it's enough with 1.3 so for now I am leaving them both. I did this system wide, with PowerShell, following the instructions in THIS THIS article.

But then there's Firefox. I don't know if Firefox can establish SSL (or old TLS) connections despite the system "ban". But I came across THIS THIS article about how to enable TLS 1.3 in Firefox and when I went in about:config and I typed "security" I saw that there are a lot of voices with SSL and a lot more about TLS than just the security.tls.version.max mentioned in that article, so I am here to ask you what to do to be 1000% sure that all SSL and older TLS are completely disabled in Firefox, and that only TLS 1.3 is enabled.

If you have reasons to believe that disabling TLS 1.2 is not a good idea, let me know, but in THIS THIS article I've read that 1.3 is much better and it's anyway backwards compatible with 1.2 in case some server only supports 1.2, so I decided to leave only 1.3.

Thanks!

This message is to inform you that my email is being leaked from my Firefox browser, in hopes that Mozilla will provide a fix ASAP (if it hasn’t already done so in the latest version?). This leak was made known to me after visiting several websites (sites I've visited previously and sites I’ve NEVER visited before!), where I will receive an email very shortly, if not immediately after visiting and closing the browser tab for the website. (These are legitimate sites that are selling a product and, typically, very politely asking if I need more information, etc. ).

After noticing this, I got in the habit of clearing Firefox memory frequently, if not after every site I visit; but especially when my email is required to login. However, today I just notice that my email address is “permanently” located within the Firefox browser; and have to wonder if this could be how websites are getting my email… The email is located in the Firefox addon Video DownloadHelper app. The Companion App within Video DownloadHelper requires a payment, license #, and email to install. And, when looking thru its new menu today, I noticed my email (the same one I get messages from after visiting sites) is right there within the Video DownloadHelper menu (click on VDH icon, click on gear icon, click on More settings…).

So, I don’t know for certain whether my email is being compromised after logging in to a website and not immediately clearing memory after leaving the website OR if the compromise is from the Companion App within the Firefox Video DownloadHelper app, OR possibly both(?). If it is being leaked from Video DownloadHelper, I would greatly appreciate it if Mozilla would implore upon the VDH crew to remove it from the app.

And, if you can, I would greatly appreciate an email letting me know if/when this has been fixed! Thanks! Regards, Dave

I cant get rid of this unsolicited "sign in with google" prompt which has cost me untold lost time having to type things over because it pops up when im looking at the keyboard while typing , getting noplace ! It is deliberate harassment !

I DO NOT HAVE ANY GOOGLE ACCOUNT AND WILL NEVER HAVE A GOOGLE ACCOUNT .

Therefore I can't sign in using any google account ! Why then do I get this trash ? All the recommended ways to shut it off don't work ! They all talk about going to google account settings ! As I've said , I do not have any google account ! Therefore I can't go to any settings ! I can't get rid of this unwanted harassment !

I want to get rid of this garbage and never want it to come back after any BS "updates"
