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

Hi, recently I encountered a werid popping sound while listining to music on YT. Firstly as I wanted to change my old DAC I swichted to a new one (every reason to buy new stuff is good), but now it is unberable. I spend some hours trying to figure out, watching tutorials etc. disabling all the stuff from device manager, checking if fast boot option is disabled, rolled back drivers, swithed to USB 2.0, disabled all of the extentions etc. etc. (the sound popping was only in youtube, but I figured maybe its due to my hardware or something). However, I found out that clearning cashe works for a couple of minutes, and browsing on incognito tab also works for some time. This leads me to belive that maybe a new updated is somehow messing it up, or google really wants me to use chrome. Any advice would be helpfull. Thanks

When is Firefox (across devices) going to bring "Tab Groups" in-built in 2025 as it is difficult to ditch Chrome esp., if it is related to work or research and similar tabs are opened up?

I have to rely on chrome and edge for same and both have not only brought it but improved it considerably. Also, chrome has not brought for mobile devices so grouping of tabs is more easy and simple but when I look at Firefox and Firefox based browsers, I see nothing of that thing present. The addon esp., Simple Tab Groups (https://addons.mozilla.org/en-CA/firefox/addon/simple-tab-groups/) is unreliable (see reviews).

If Firefox want us to use their browser and as default, they should see why we are using Chrome and Edge (latter, having vertical tabs in-built, also).

I hope 2025 is a year Firefox learns of how to retain users across devices. Currently Firefox is more from 2005.

Browser Choice Alliance wont be helpful if browsers like Firefox dont see users and their reviews and posts and issues reported. "https://browserchoicealliance.org/"

3 years post and still no work, and Firefox wants us to use their browser over Chrome and Edge. Why? And how?

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.

Been using Firefox since the 90s, on macbookAir since 2010s, Firefox is my only preferred browser.

But this glitch has been happening for many years, and I just don't understand why Firefox don't fix it.

I frequently reboot my Firefox (generally by Force Quit, sometimes by quit/X-ing out.

Inevitably, when I reopen Firefox, the previous tabs don't open... that is, until I hit the "trouble resorting pages" button, followed by full restoration of tabs.

Can we just skip the "didn't work" button, and just get it to work?

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

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.

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.

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.

Hey there

When streaming on Firefox or using Zoom the video image pixalates in a mostly green tone. I have attached a pic. It doesnt seem to happen in other browsers.

Ideas?

I would like to take a screenshot of my expanded emails on protonmail.com - but it is not working when when I click "full page" option. Is this possible? I don't want to take screenshots manually by scrolling down the window...

I'm not sure what type of issue this is, so hopefully I’ve posted it in the right place!

Devices:

• Firefox version 133.0 on 2022 M2 MacBook Pro OS Sequoia 15.1.1
• Firefox version 133.0 on iPhone 16 Pro Max iOS 18.1.1 (*for reference, of checking issue, not where issue is occurring)

Issue Breakdown: While updating my bookmark's tags in Bookmark Manager, my tags all but disappeared and other strange things started happening.

• My tags aren't in the sidebar menu of the Bookmark Manager at all. See Screenshot 1.
• Already tagged bookmarks retained the tags, but I’m unable to edit, add, or remove bookmark tags at all. When the bookmark is selected, the bookmark’s tags, nor any other tags, appear in a list under the bookmarks tags. See Screenshot 2.
• I can locate all bookmarks with the same tag by searching bookmarks in the Bookmark Manager.
• I can move and rename pre-existing bookmarks.
• I can add new bookmarks (confirmed by the blue star beside the address bar on the main browser after exiting and re-entering), but I cannot find those bookmarks anywhere in Bookmark Manager.
• My mobile bookmarks folder isn’t shown in Bookmarks Manager, but I can view 11 bookmarks in my Mobile Bookmarks folder on my phone’s Firefox application.

I’ve tried the following:

• restarting Firefox by quitting the application
• refreshing Firefox through the browser [https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-se...]
• restarting my computer
• clearing the startup cache
• clearing the cache [https://support.mozilla.org/en-US/kb/how-clear-firefox-cache|link]
• restarted in Troubleshoot Mode [https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubl...]
• uninstalling then reinstalling Firefox software

I have no idea what is wrong with it or what is going on. What else can I do?

I have a typical search bar at the top of the browser window. Recently, as soon as I begin to type a search, the bar expands to cover the whole top of the browser window. How do I stop this from happening? It's unnecessary and irritating. Firefox 133.0, Win 11

I recently started having a problem with my banking website. Before I could investigate or report it, Mozilla released a bug fix 1923500 "Firefox 131 Enhanced Tracking Protection major breakage of multiple banks Bill Pay services" I have updated to Firefox 131 however, there may still be a problem, however before I report it I'd like to verify if it's simply that their link is broken. Let me explain: On my bank's website there is "Payment Inquiry" link with this link "https://paybills.MyBankName.com/imm/Auth/SLO/4661?ReturnUrl="

What happens is that it sends me back to the login screen, I navigate to the Payment Inquiry again, click the link... rinse and repeat... in an endless loop. I suspect that the URL is malformed because there is nothing following the "=" sign. I would expect something to follow the equal sign. Is this indeed a bad URL? Should I pursue with my bank? I only ask because is seemed more than a coincidence that this occurred near the same time as bug fix 1923500.
