Hi, I just installed Windows 11, version 24H2 and now in Firefox I'm continually prompted with "Awaiting Location Permission, Grant Firefox location permission in system settings".

The problem that location has been turned off by admin on this computer. How can I stop these continual prompts from Firefox? I have checked the box in Settings to block location requests from new websites but am still getting the prompts.

Thank you.

I was trying to sync my settings to my new laptop with my login and PW (which was correct) and it kept telling me it wasn't right. So, I decided to change it but my MFA on Google for Firefox got wiped once I switched phones. I had to use a backup code to get in and want to re-enable the MFA.

Unfortunately, and for no real reason, it won't work. I scan the QR code in Google Authenticator, it sets up and gives me a code, I enter the code, and then it tells me it's the wrong one. I even tried to do it by manually setting it up and it made no difference. Now I can't re-enable it because it won't work right.

What the actual hell is going on here, guys?

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

I have a HUGE problem with Firefox memory usage. Some open instances of firefox are taking anywhere from 600mb to 2.8gb of memory. Since firefox opens MANY instances even with only ONE active window, this very quickly uses all available memory (4gb) causing a full laptop crash.

More concerning is that CLOSING the worst instance of memory usage STILL leaves the single open page/tab open, so what exactly was the memory eating instance actually doing ???

I have included a screengrab of the many remaining instances of firefox in windows task manager AFTER closing the main culprit.

I have also included a screengrab of all the adblockers I use which I believed would limit unnecessary memory usage, but does not seem to be effective.

Many Thanks

I got an email supposedly from breach-alerts@mozilla.com that claims there are currently 3 data breaches and has this link to resolve: https://blrv1ly5.r.us-west-2.awstrack.me/L0/https:%2F%2Fmonitor.mozilla.org%2Fuser%2Fdashboard%2Faction-needed%3Futm_source=monitor-product%26utm_medium=product-email%26utm_campaign=monthly-report-free-us-scan-no-exp-yes-breach-resolved-no%26utm_content=resolve-exposures-us/1/01010195ceba1024-6e3f74fe-119a-4e2e-9033-398671a830d9-000000/DDeGOTLjROOXCCk2fJvXJbdefc4=419

This seems like a phishing email, is it legit? Should I find another browser?

I encounter this message "Peer’s Certificate has been revoked. Error code: SEC_ERROR_REVOKED_CERTIFICATE" when connecting to "Site A" using Firefox version 122.0 (64), my primary browser. I have successfully connected to "Site A" using Firefox in the recent past.

I can connect to "Site A" without errors using my backup browser, MS Edge Version 121.0.2277.83 (Official build) (64-bit).

This seem to be a Firefox related problem.

Greetings from North-East of France, since a few weeks ago I'm seeing a (sort of) pop-up window suggesting to login with a Google account (see the screenshot attached). I've done some internet search to find out how to get rid of it, but the only suggestion I get is to modify an option in a Google account. However, I do not have a Google account! How to get rid of this disturbing pop-up? I already use Adblock Plus and uBlock Origin, yet Google passes through them! Thank you in advance for any help you may provide.

I had a personal certificate installed in Firefox and it was working well. It expired, so I got a new one from the same provider. Both appear in Firefox under "Privacy & Security" -> Certificates -> View Certificates... The previous one is not valid any more, and every time I try to access some page with a certificate, it uses the old one. So I tried to delete the old one. Nothing has worked so far. Doing the straightforward way of selecting it in the Certificate Manager and deleting it makes the certificate disappear from the manager menu, but if I enter the certificate manager again, it is there again. I tried to delete both certificates, same issue, both reaper in the manager. I tried to delete them, close firefox, delete cert9.db, cert8.db and key4.db and nothing. Only thing left is delete my current firefox profile and start again... Any other idea or something that I might delete before to solve this?

Hi,

Recently, I have noticed that when using Firefox, if I try to view an embedded YouTube video on sites that I visit regularly, instead of the embedded video playing, I now get a message on the video window that says, "Sign-in to confirm you are not a Bot. However, there is no option to 'sign-in', so I am not able to view the video. (screenshot attached)''

I did a little testing and discovered 2 things which I thought were noteworthy:

1) If I turned-off my VPN (Norton), then the embedded video plays in Firefox without any issues.

2) If I access the same site within the Chrome browser then the embedded video play regardless of whether I have the VPN service On or Off.

Strange, but true !!

I cannot find any Firefox Settings that address this issue.

Any clues?

Thanks.

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!

After watching this video https://www.youtube.com/watch?v=mAfY_bNJTBI i went to https://www.cloudflare.com/ssl/encrypted-sni/ and did the test. Result is 3/4. (See screenshot below) Secure DNS, check DNSSEC, check TLS 1.3 check Enrypted SNI, fail In Firefox i tried doing exactly what the person did in the video but i dont have the settings he is showing in about:config Why is that? (Below you can see the screenshot, those settings are missing from about:config)

So my question reamins simple, how can i enable Enrypted SNI in Firefox?

I have my Firefox Firefox Privacy & Security History settings set to 'Always Use Private Browsing Mode.' Yet every time I open Firefox and visit the History tab, 'Recently Closed Tabs' shows a history of the websites I've visited. How do I disable this feature?

The camera won't turn on in the Firefox browser for Google Meet or Zoom. It says it can't find the camera or that it's turned off. I have checked my Windows 11 settings and desktop apps have access to the camera. I have also checked the settings for each of the sites and use of the camera and microphone are allowed. Autoplay is enabled too. The camera works fine in other apps and in other browsers.

I am running Firefox 126.0-1 on an Arch Linux system. Most websites are failing to connect for security reasons.

Some sites, including google.com and nytimes.com, fail with an "SEC_ERROR_UNKNOWN_ISSUER" error, and their certificates confirm that they are respectively issued by Google Trust Services LLC and DigiCert Inc.

The website archlinux.org errors with "MOZILLA_PKIX_ERROR_MITM_DETECTED", stating that "Software is Preventing Firefox From Safely Connecting to This Site", citing in particular ISRG Root X1 as the problem. The certificate confirms that it is issued by Let's Encrypt.

The website duckduckgo.com simply errors with "SEC_ERROR_PATH_LEN_CONSTRAINT_INVALID" and states "Secure Connection Failed"

I have confirmed in preferences that my proxy settings are set to "No proxy" and the problem persists across troubleshooting mode and making a new profile. I have also tried removing the cert9.db file in a given profile folder.

When I visit an http site and specify a non-standard port, it automatically changes to https, which is not a site redirect but something Firefox changes. This site already has an https service, and the http service will redirect to https. I reproduced the same situation in chrome. Accessing the http service with a non-standard interface was normal. After accessing the https service once, the service with the non-standard port was also changed to https. Clearing the data will restore it. Is this cached? My HTTPS-Only Mode is turned off, and set an exception for this site. thx.

Can't log into router. Works with Chrome and Edge 192.168.2.1

Tried this says in the router's Admin page: Access setting page via https://router.asus.com:8443 * Please use port 1024-65535. With and without :80 and :433

Tried everything I can find on this site and Google. Has worked for many years.

When I try to go to my webmail I sometimes am presented with a Deceptive Site Ahead warning.

I am quite happy that although the SSL might not be current that the website is safe for me to go there. How do I stop this annoying feature from activating?
