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 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 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

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.

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!

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?

Recently transferred from Chrome. My understanding was Firefox private browsing was supposed to work similarly to chrome incognito mode; once you close the browser, all local files are deleted and cookies are cleared.

However, with Firefox it maintains my logins. If I log into an account while private browsing and the close the browser, I’ll still be logged in next time I go to the website even if it’s days later (and I have never logged into this account in a non-private browsing window!)

I never had this issue using chrome incognito, so it seems to be a Firefox problem.

Is this just not something Firefox supports? Is there any way to prevent storage of cookies and private data?

Hello everyone! I want to see every visit on a site by date and time. But in library of history it offers me to see only last visit by date(for example if i visited a site for example x.com 200 times - i want to see every date and time of every of these 200 visits, but not only recent). How to do it?

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?

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

Hi, it seems that my Firefox browser does not want to save a new payment method. I'm trying to access "Settings -> Privacy & Security -> Autofill" and then click on "Saved payment methods", which opens a dialog with the existing payment methods and options to remove/add/edit. I'm clicking on Add, filling-in the card details and then clicking Save, nothing happens....

I previously had a working saved payment method, but it stopped working (I think more than 6 months ago). I tried to re-enable the credit cards by setting the following configs on about:config page:

- extensions.formautofill.creditCards.available: true
- extensions.formautofill.creditCards.supportedCountries: '...,RO' -> (I was adding my country to the existing list)

After the browser restart with those new settings when I'm on a payment page, clicking on a credit card field will show the saved credit card but if I click on it, it will not fill the details. And also trying to save a new card, manually as described previously in this message, or by the automatically prompt to save a new card after a successful payment was done. Both methods failed on me but with no error (I cannot see the saved payment on the list).

I tried removing the existing saved card, it worked removing it, but the add is still not working.

I also tried restarting in save mode, launching Firefox in a separate profile and added my country on the creditCards config for supportedCountries to show the "Saved payment methods" button on new profile, and it did not change anything.

I'm thinking there is a missing permission somewhere on the disk but I don't know where is the payment data stored on disk.

I would really appreciate any help on this.

PS: Check the attached pic to see the payment add and clicking the save button does nothing (also there are no validation errors). And the other: FF version, OS, troubleshooting info.

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.

I have been watching YouTube for years, issue free. This week I was blocked, as my computer may be blocking ads and thus violating You Tubes policy. How can I find and disable ad block programs/ extensions, thus allowing me to get back on You tube. I can recognize an outright program, but do not knew if extensions are in play that are not obvious to me. THANKS

I use a privoxy hosted on my home server to route Firefox traffic through a VPN. It usually works fine, but I am trying to set a few services to bypass the proxy using the "No proxy for" box in the Firefox connection settings - specifically streaming sites like netflix, hulu, and plex. Despite putting these domains in the "no proxy for" box, the proxy still seems to be applied - ie. Netflix fails to stream as it would if I were connecting through the VPN.

To test, I also tried adding "whatismyipaddress.com" to the "no proxy for" box, and this did successfully bypass the vpn (showing my real IP), so it is working to some degree. I can also confirm that that site shows my vpn IP when it is not on the whitelist.

I assume that these streaming services are connecting to a different domain when streaming video, which is not on the whitelist to bypass the proxy because I have not added them. Does anyone know if this is the case, and if so, how I could fix the issue?

Thanks.

I come, trying to manage my disappointment and anger, to say only one thing: I love Firefox, it (still) has the best UX of any modern browser. And part of that is that it has NO AI malware built into it. The recent statements from the CEO regarding the implementation of AI into the browser is extremely disappointing, to the point of it feeling like a personal betrayal, and will only make me (and a lot of other people) just completely abandon it. And don't kid yourselves, your user base never was so low, and that user base only like this browser specifically because it has no malware built into it, because of the privacy and open nature you had before this debacle. You're shooting yourselves on booth feet and an arm with a shotgun. I don't trust you as a company anymore at all; you just achieved the complete opposite of what you said you wanted. If you just made use of reverse psychology and was that's your actual goal, congrats. This company quite literally couldn't have elected a worse person to be chief executive.
