Firefox Support Forum

Is spell-checking done locally on my computer, or is it done on the Mozilla website? I just found out that the Chrome and Edge browsers send my typed message to the home office, and that is where the spell-checking is done. Can I assume that this process is done locally on my own computer with Firefox?

I've been paranoid about security for many years, and every little bit of info I can add to my personal well-being lets me sleep that much better at night.

I am currently 82 years of age and have been using Firefox since it first became available, just because of its advertised security features. Quite happy with it and hope it stays on top of my needs.

And I have the same question regarding Thunderbird and its security properties.

Thank you.

I'm getting daily warning notifications from Mcafee about some virus. Don't even have Mcafee. When I go to Settings -> Privacy & Security -> Notifications, there is no Settings button to modify push notifications.

I don't know why the page https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es is marked as insecure in Firefox. I tried in Chrome, Edge, IE... and the page is marked as secure, the certificate is recognized.

I attach screen captures of Firefox and Edge examples.

I've the security.enterprise_roots.enabled setting enabled.

If I check for Firefox error details, I see (auto-translated to english): https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es The issuer of the other end's certificate is not recognized. Strict HTTP transport security: false Setting HTTP public keys: false

117.0.1 Mozilla Firefox Snap for Ubuntu installed Total Adblock installed Enter URL "my.yahoo.com", the "My Portfolio" page comes up, the portfolio box presents a message: "Oops, something went wrong. Please try again." I went to Settings, Manage Exceptions, entered "https://my.yahoo.com" and clicked Add Exception. "https://my.yahoo.com" it appeared in the Website listing below. I clicked Save Changes. I retried the My.Yahoo tab again and the same error resulted. Where do I need to change what preferences, Yahoo or Total Adblock?

Firefox was working well on HTTP websites until a few days ago, but now HTTPS-Only Mode seems to be permanent. Despite changing settings to 'Don’t enable HTTPS-Only Mode', when HTTP sites are selected I get the same message as for 'HTTPS-Only Mode'. Also, if I select 'Enable HTTPS-Only Mode in all windows' and add exceptions, I get the same result.

For some reason I can't access the Spotify website (spotify.com or https://open.spotify.com/). I get this error message:

Page not found - We can’t seem to find the page you are looking for. Any ideas? This is infuriating. I'm on a Mac running Ventura and the newest version of Firefox. Thanks.

I'm trying to connect to my Schneider XWPro Gateway for access to my solar inverter, and security policy on Firefox no longer't allows access. I can access using Safari by explicitly allowing access. Error from Firefox is as follows:

Secure Connection Failed

An error occurred during a connection to 192.168.1.120. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem

Your error message states there is a problem with a certificate conflict, however there is no apparent way to tell which certificate is causing the conflict, so there is nothing I can do about it. This is a new problem, I have been able to access this device in the past.

Any suggestions?

Has the Autofill Forms option been removed from the latest version of Firefox? I get the opportunity to autofill credit cards but the Forms section seems to have vanished. Am I missing something? Thanks.

firefox is not prompting the primary password login dialog box and not even providing me "saved login"

Even when i tried to open password in settings so that i can manually copy paste them, it ask me to log in first as shown in picture but when i click on login, nothing happens, it does prompt primary password login dialog box.

as shown in picture below, even if i click login, it just does not work.

p.s tried clearing cash and cookies.

I occasionally use a site (www.zoomcare.com) which does not work properly with Firefox (I've been using Microsoft Edge (Windows 10) to access it). The problem comes when I try to login. I enter my username and password, and that brings up a blank page that does not redirect to anything, so I'm stuck.

Just out of curiousity, I was looking through Advanced Settings, and found security.csp.enableNavigateTo. It has been set to false, but when I set it to true, I am able to successfully login (I still go to the blank page, but after a brief pause, I'm redirected to a logged-in page).

I'd like to know something about the security implications of enabling this property. Is it a bad idea? (Not knowing, I've set it back to false and will continue to use Edge for now).

Hi, I have been wanting to switch to Firefox for a while now and I have imported all of my data from Chrome onto Firefox. All the other members of my household use Firefox on their Mac laptops and iPhones. I have only ever signed into my own account on Firefox, and in the same way I have only ever signed into my own account on Mozilla VPN, which I have used for over a year while living elsewhere and have never had a problem with this. I also have only my own Google account in the data imported from Chrome. I have no one else's information for any account on anything in my device nor, to my knowledge, do they have any account information of mine on theirs. However, sometime in the 10 or so months since I imported my Chrome data - around the same time I moved into a house with others who use Firefox - my laptop's Firefox seems to have...connected somehow, in a way atypical with normal syncing, with the other devices in my house. Occasionally, when I open Firefox on my computer, whatever tab another household member has open on their computer will open instead of a homepage. Also, a little icon pops up occasionally to tell me Firefox is "open on iPhone" when another household member is using Firefox on their iPhone. I use an Android which does not have Firefox installed, so it's not a glitch syncing with my own device. I do not know how this happened and I do not know how to stop it. There doesn't seem to be any evidence of this connection in any place I can see in the preferences window, nor can I find any way to permanently unsync my device's Firefox application from anything unless I sync something first. Any ideas? I'm not that terrible with computers lol, I swear!

While reconnecting one of my computers to my Firefox account I saw at the top of the Settings Page: "Your settings are being managed by your organization". Problem is that I don't belong to any organizations or enterprises having anything to do with my online life. I have been hacked in the past and am paranoid when I see something that doesn't make sense. When I click on the link (trusting that it is indeed from you), it takes me to your Enterprise Policy page showing the following:

Active Policy Name Policy Value

DNSOverHTTPS Enabled false Locked true

I always use secure DNS (DOH or DOT) on everything - network adapters, routers (except the ISP one whose default I can't figure out to circumvent) etc. but on the browser setting pages I am only given the option of having it off: the default, increased, and max protection options are greyed out and cannot be chosen. I guess that explains the policy values but who locked it? My only guess is that is use a Surfshark VPN and realize that in so doing I am using Surfshark's DNS servers but I believe I had this problem before using the VPN. Any help would be greatly appreciated. Thanx.

version 117.0 about to update. I am a SQL Server specialist, and know virtually nothing about web servers, browsers etc. I need to access the AZURE Portal in a private window to give access to a legacy login. I am now getting the firefox enable HTML5 Storage (Local and Session) in a private window before I can continue. I can get in fine in chrome without doing anything at all. What do I need to do in words of one syllable, such as go to the 3 bars, find this option, change this to that etc. Apologies, but any developer technical words about the web, or browsers will make my eyes to glaze over! It was all working up to about 1 week ago - new version with new options? Thanks, Clive

Hi, I accidentally allowed notifications (while using Firefox) from a particular web site only to find out that now I get numerous notifications regarding phony virus alerts, etc. I am unable to block the notifications.

I searched the web for how to block a notification from a web site, but have not come up with any solutions.

In particular, I went to about:preferences > Privacy & Security > Permissions > Notifications. The web site is set to Block, but still the unwanted notifications continue. Perhaps the notifications are coming from a different web site that seems to be hidden?

I also quit Firefox and restarted Firefox, but the notifications continue. I also restarted my Macbook Pro, but that didn’t help either.

Here is the link I originally clicked on, but I obviously wouldn’t want anyone to click on it:

I would be so grateful if anyone has a solution!

On a late model Dell laptop, there are no domains listed under Exceptions-Cookies and Site Data. When I key in a domain (whether using www., http, https, or just the domain name by itself.) and click on Allow, that website is not added. It's the same as if browser security is stuck on Remove All Websites. With the same Privacy and Security settings on my desktop, I do not have this problem, so it appears not to be a matter of altering particular settings. Short of removing and reloading Firefox on the laptop, which might work but not teach anybody anything, are there suggestions?

I am using an extension that automatically deletes cookies on Firefox startup. But when I start firefox, I am getting sites listed showing they have one or more cookies but are using no storage. Another Firefox extension indicates there are no cookies from the sites that "Manage Cookies and Site Data" says do have cookies.

Is this a bug in Firefox, a bug in the extension, or a misunderstanding on my part?

I use FF 116 on windows 11. For months, I have had problems logging in to web sites. At first I thought the problem was with the web site, but I have come to the conclusion it is an FF problem. GlobeandMail.com, gem.cbc.ca and rbc.com for example ask for me to log in. I go through the steps giving my password and login name and the web site seems to accept these without complaint but it continues to want me to log in. I end up having to use Edge which works fine. Is there a solution?
