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?

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

"You will have to visit each link (i.e. click the bookmark) to make Firefox retrieve the favicon"

That the common advice. Never works for me. If it was actually going to work, wouldn't it be when you originally create the bookmark?.

Having these favicons saves time, makes you workflow easier. Am I correct that the problem is with the given website making it available?

How do I remove the sidebar permanently. It is now as I said above about 2.5cm wide and growing! I want it gone and none of the solutions give any idea how to do this. The show/hide button only made the damn thing expand!

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?

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?

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

I have a 1848ETC-HST data logger from Real Time Automation on an isolated network that does not support HTTPS but Firefox keeps changing it to HTTPS. I tried a private window with the same results. HTTPS-Only Mode is disabled. I entered an exception even though it should not need it. It was working in Firefox at one time and it still works with safari and chrome.

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

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 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?

All of my desktop bookmarks are on mobile, but after resetting my password they won't sync back to my desktop. I can't even access them from my desktop, despite browsing data still being clearly accessible. I have 10 years of bookmarks on my mobile device that for whatever reason now will not transfer to my desktop firefox no matter what I try. Since there's no way to manually export to xml on mobile I have no way of accessing these and I am at risk of losing 10 years of bookmarks, many of which are vital to the work I do.

Hello,

I have a huge problem with Shortcuts not syncing in the main page. I have my shortcuts organized and pinned how I like it but every single time I sync new machine or mobile, the shortcuts are not being synced and they are completely out of place and sometimes gone on my main machine. This cannot be like that and should be properly synced.
