Hello, I am running Firefox on a W10-Pro PC. I always click the lock to check certificate validation. In the last month I keep seeing "Connection verified by a certificate issuer that is not recognized by Mozilla".

When I click for more information I see that "Norton Web/Mail Shield" does not recognize the certificate issuer. When I click on Learn More it takes me to a Firefox site "How to disable the Enterprise Roots preference" I also checked W10 certmgr.msc and I see Norton is listed. Images included below. I would love to resolve this issue. Thank you for your time.

'Linked In' technical support are telling me that I am unable to see certain pages on their system most likely because my Firefox Browser (which is fully up to date) is using DNS. They said to remove DNS. Is this wise advice and if so how do I do that and what difference will it make to my day to day use of firefox?

Been using Firefox since the 90s and been on Mac since 2000s. This problem has been happening for about a year, throughout three macbooks (my old one, a temp one, and my new one) and multiple Firefox updates. I'm always updated and always clear cookies daily.

The failure to move bookmarks I can overcome by rebooting Firefox with a Forced Quit. If I only have to do this every few weeks, then no biggy reinserting all my passwords for all the different sites I use (and no, I don't want to use password managers, I don't trust them)

Today it happened within hours of Force Quitting Firefox, this is too much!!!

The only reason I didn't report this problem earlier is I simply expected an eventual newer version of Firefox to fix this bug.

Firefox 133.0

Normal behaviour: click-drag bookmark within bookmark menu pull-down to position where I want bookmark Failure behaviour: click-drag fails to move bookmark, until I reboot Firefox, then it works again

Help,

I received 2 email today saying:

Your Mozilla account was used to sign in Firefox on Windows 10 Thursday, Dec 12, 2024 3:40:09 AM (+07)

and

Your Mozilla account was used to sign in Wednesday, Dec 11, 2024 10:45:31 PM (CET)

Are these legit? How can I know?

Each say from mozilla.org/firefox

I've been having issues with Cross-Origin Request Blocked errors for a while now. I'm on Windows 11. I first noticed this issue when visiting YouTube. I would go to play a video and any video I tried to play would just load forever and never play. Then I noticed I was having the same issue on Facebook. The page would load but then a majority of the images wouldn't. I can use YouTube and Facebook just fine on Chrome. The reason for the error shows as "CORS request did not succeed". Initially I tried uninstalling all of my extensions. Then I completely uninstalled Firefox using Total Uninstall (for good measure). Nothing has worked. I'm not sure what changed that would cause these errors. Could this be a network issue? I've been having issues with certain sites on my Macbook Air as well (Chrome and Safari) but I thought maybe that was because it's pretty old and not supported by apple anymore.

I'm running Firefox 122.0.1 on a Windows 10 desktop PC, with a profile which includes a userChrome.css file which makes several layout and cosmetic changes.

I also have a laptop (also Windows 10) which has an old Firefox 97.0.1 installation, and I'd like to make the same changes on this machine which I'm used to on the main computer. I copied my desktop profile to the laptop, to the same directory as its present profile, but when I rebooted Firefox the transferred profile wasn't recognised.

While doing the transfer I received error messages about some of the folders: Destination path too long. This despite the fact that the registry flag to accept extended paths is set to 1. I had to skip several folders in order to complete the transfer.

Could this be the reason why the new profile isn't being picked up? Or is it because the two Firefoxes are of different versions?

I'd be grateful for any thoughts. Many thanks.

hello last few days this started.... been in dark mode for years now,,,, on utube trying to add a comment,,, the typing is blacked out so i cant see it until after its posted .. i can search on utube as the text comes out white ,, just while making a comment it is black on black and cant see what i am typing ,,, the comment when posted shows up as white on black .. hope thats easy to fix lol thanks mike

Unable to view YouTube comments using Firefox on android. I can view the comments on Opera, duckgo and chrome.

This problem started about four days ago. Comments show on the short videos but not the regular videos. When I tap on "comments" the resulting page/frame is empty.

I have Win 11 dell computer that does not play or pick up sound from web sites videos .I checked and tested my sound using the Microsoft platform & buy playing a disc. It works OK

When I click submit on a form and switch tabs before it completes processing and return to the tab after the page is not refreshed with the new page returned from the server. However, the action has completed on the server. This only started happening in the last couple of weeks. Note: if I stay on the tab without switching it is fine.

I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings

Hello,

I just did a full windows defender scan and it turns out Trojan:Script/Wacatac.H!ml popped up when it was done and it said the files affected were:

containerfile: C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles\.default-release\cache2\entries\InsertHashHere

file: C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles\.default-release\cache2\entries\InsertHashHere->(GZip)

I removed the hashes or whatever they were behind the entries, I was wondering if this was a false positive? I didn't notice any slowed down or hacked accounts, also windows defender quarantined it. I've also reinstalled Firefox and deleted all folders associated with Mozilla in AppData.

Hi,I watching Iprime Movies & Many other Streaming Services A Notice appears on the screen ,Change youe provider(likes of Firefox) to Hd Please assist Thank you Darryl

Firefox has an excellent built-in screenshot feature that allows users to take full page screenshots of web pages. I am a Mac user. I use Sugarsync cloud service to keep my Mac Studio desktop (OS 12.6.3 Monterey) and Macbook Air (OS 13.3 Ventura) laptop in sync. I am running Firefox 133.0.

I have noticed that Firefox .png screenshots have not been uploading properly to Sugarsync for the last 6 months or so. In Finder a green tick appears which indicates that a file has been properly uploaded to SugarSync but when I go to the Sugarsync app I can see the following error message for such files "Waiting on upload from Mac Studio". This means that screenshots I take on my desktop do not go across to my laptop and vice versa.

I spoke to the very helpful tech support (Luis M, senior tech support) at Sugarsync today and he and his colleague were able to figure out that the problem has to do with the attributes of the saved .png files.

I will outline the issue in detail:

On a Mac you can examine the attributes of a file by doing the following: - right click on the folder in which your file is located and click "new terminal at folder". This opens a new terminal window - type the following: xattr -l and then drag and drop the file name from finder next to the "xattr -l" and then insert a space, a dot and a forward slash and press enter, i.e. myusername@NameOfMyComputer Foldername % xattr -l full path and file name ./

For example if I take a screenshot of the following URL: https://www.mlb.com/ and I save the screenshot in a folder I have named "Firefox Screenshots" it saves as as "Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball" on my computer. I can examine it's attributes in terminal using the steps outlined above:

myusername@NameOfMyComputer Firefox Screenshots % xattr -l /Users/myusername/Firefox\ Screenshots/Screenshot\ 2024-12-07\ at\ 14-46-28\ The\ New\ York\ Times\ -\ Breaking\ News\ US\ News\ World\ News\ and\ Videos.png ./

When I click enter it generates a massive amount of information that looks like this: /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-46-28 The New York Times - Breaking News US News World News and Videos.png: com.apple.metadata:kMDItemWhereFroms: bplist00?_ /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-46-28 The New York Times - Breaking News US News World News and Videos.png: com.apple.quarantine: 0081;6753c517;Firefox;0F67116D-C970-45CB-A578-65EAFC93F6DD myusername@NameOfMyComputer Firefox Screenshots % xattr -l /Users/myusername/Firefox\ Screenshots/Screenshot\ 2024-12-07\ at\ 14-48-02\ MLB.com\ The\ Official\ Site\ of\ Major\ League\ Baseball.png ./ /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball.png: com.apple.metadata:kMDItemWhereFroms: bplist00?_Q?^data:image/png;base64,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 etc etc etc

The total output is over 19 million characters long due to the long alphabet soup that is generated. And this why Sugarsync is unable to properly upload the file.

You can retrospectively fix folders that contain .png files that will not properly upload to Sugarsync by right clicking on a folder, selecting "new terminal at folder" and typing the following: xattr -d -r com.apple.metadata:kMDItemWhereFroms ./

This fixes the attributes and the .png screenshots files immediately start to upload to Sugarsync. When you examine the attributes of the file again it shows the following:

/Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball.png: com.apple.quarantine: 0081;6753c575;Firefox;D5072DFA-9EE8-4EF1-9658-86263462F1CD.

Could the Firefox developers please look at this issue and liaise with Sugarsync?

Many thanks in advance.

Why can I no longer access my yahoo customized home page. And how can I create a new one, tho I'd rather not have to go thru all of that setup again. Hope you can help me retrieve it. Started yesterday I think.

I want to copy/clone information in my Firefox Profile (Bookmarks, Logins, ..) from one device to another. Once that was accomplished, then I would enable Firefox Sync for the two devices.

Scenario: Device “A” (Profile A): Primary/Original/Source Device “B” (Profile B): Copy/Clone/Duplicate

I understand that if I set up Firefox Sync first and then sync the two devices what I will get is a combination/fusion of the information on the 2 devices, i.e., all the “good” stuff in Profile A plus all the superfluous stuff in Profile B that I would just as soon ignore/delete – which is not what I want. This issue has been raised in a number of other posts on this forum but with no suitable resolution offered (that I could find). I’m wondering if there might be a “work-around” that would achieve the desired result.

So ... would this work?

1) Back everything up first (of course!) 2) Glean any unique information to be preserved (Logins, etc.) from Profile B and incorporate it into Profile A (Profile A now has everything essential!) 3) Purge Profile B

   a) Create a New Profile on Device B (and delete old?)
   b) Delete everything possible from the new Profile B (default bookmarks, etc.)

4) Login to Mozilla account and enable Sync

The idea is to create a “blank” Profile on Device B so that when Profile A and Profile B are Synched together (combined), Profile A remains unchanged, and Profile B is populated with everything in Profile A (a perfect copy!). The result that I want after Sync is essentially A+B=A, the solution of which is of course B=0, hence the focus on creating a "blank" Profile B.

Instead of purging Profile B as above, an alternate method might be to first “pre-load” Bookmarks in Profile B by the usual method of Backing up Profile A Bookmarks and then Restoring them to Profile B. At this point Profile A and Profile B Bookmarks would be exactly the same and Synching the two devices should make no changes to either’s Bookmarks. Logins and other information would still have to be purged, but this could at least be a head start.

Presumably this idea could be extended to more than 2 devices (but with only one being the “Primary”).

Note that I am (myself) only concerned about Bookmarks and Logins, and am thus glossing-over how other information that might be important to others (Browsing History, Tabs, etc.) might be Synched.

Could someone from Mozilla/Firefox with a knowledge of the inner workings of these features please comment as to the efficacy of this “work-around”?

Thanks.

We apparently lost power sometime during the night. When I turned on the monitor and opened FF, I got the error message that it had crashed. As my subject line says, I lost all my tabs, the pinned ones (probably about 10) as well as the open ones (probably between 10 and 15). I also lost all my history. I can't use the 'Restore Previous Session' because it doesn't give me that option.

I've restarted Firefox and also rebooted my computer...still nothing happens. It's up to date, version 133.0. But I have no history beyond this morning. Is there any way I can recover those tabs or history?

And in my FF Settings, there's a link at the top that says "Your browser is being managed by your organization". I don't have or belong to an organization. When I click on the link it takes me to another page that says it's "Active" and there's a huge list of "Documentation" that apparently involves a lot of code. Can you please explain what all that means? Thanks so much for any help!
