I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

Hello,

Moving from an older Ubuntu 18.04 machine where Firefox is limited to version 113 to a newer machine running Mint 22 where the current version is 134.

I know how to transfer the profiles but I could not find any information on compatibility.

Would I need to install other versions before 134 to handle any changes?

Thank you

Hello, Firefox won't save my download history between sessions, history is set to remember. I tried doing the refresh on the installer and even reinstalling firefox and deleting all mozilla folders in %localappdata% and %appdata% before reinstalling. it just forgets all downloads once I close firefox.

Video Link

I'm having much difficulty in attaching a article I see to Facebook. Its possible the problem may be I'm not using the right instruction on the Firefox options when I right click the article I want to attach to Facebook. Some of those options are, Save link as, Copy link, when I right click for options. Can someone explain what is the right option to use? And, how do I proceed once I choose the correct option to make that attachment to a Facebook message I'm replying to? There are times a picture of the article will attach to the Facebook message, but the text that is associated with the attachment will not appear? Can someone please help? Thank you.

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

I am writing to request assistance with my Mozilla account. I am unable to access my account due to several reasons: I have lost access to the two-factor authentication app, I have lost the backup data with the 10-digit recovery key, and I no longer have any devices where I was previously logged in. I only have access to my email address.

I do not need access to the synchronized data; it would be acceptable if you delete it and allow me to register a new Mozilla account with my existing email address. Using a different email address is not an option for me.

I am in the process of transitioning away from the Google ecosystem and would like to use Mozilla's services and products. Could you please help me reset my Mozilla account so that I can register a new one with my current email address?

Thank you for your prompt attention to this matter.

Best regards, Evgeny

I'm having issues using Firefox with the Facebook site. Groups are slow to load and sometimes the chat and notification windows take forever to load with shimmering panels or a wait cursor displayed. I've cleared the cache and deleted the cookie, but that didn't rectify the issue. I don't have a problem with Edge.

Not sure whats going on here, been using FF for decades with no problems. I am saving bookmarks to various folders but recently noticed some were not in the folders I was sure I had saved them too. For example, in the screenshot attached I had saved the Rink Diary Bookings to my Bowls folder, but when I opened the folder later the bookmark was not shown. I did the Google search and checked what I could and most solution options were aimed at the Toolbar, which I didn't have a problem with. I then noticed some other bookmarks were no longer showing. I then saved a new Rink Diary Bookings link (now ending in '1') to a second folder so I knew which link was from each folder. This new bookmark also failed to show in the new folder. I somehow found a search button for the bookmarks and found both the bookmarks in the correct folders. (See attached) Can anyone advise how to get the bookmarks to show in, and open from, the actual folders? I am not very tech minded so any help is appreciated. I have copied the folder menu's in the attachment Thank you.

All of a sudden for the past few weeks or so, I keep getting the message in the attached screenshot when entering words in the search bar and clicking on Google. This never happened before in all the years I've been doing this, so what's up with it and can it be fixed? Thanks.

Anything using WebGL in-browser tells me that my browser doesn't support it.

https://get.webgl.org/ says "Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card." but I updated it to the most recent drivers and the issue is still happening. Graphics card is an AMD Radeon RX 6600 XT.

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

How to remove unlinked labels from bookmark organization ?

Deleting accumulated labels for deleted bookmarks

Good day,

I organize my bookmarks progressively, categorizing them by folders and labels. The labels are stored (libraries - above all the bookmarks) within their respective folder "labels". I deleted some bookmarks a few days ago and noticed that I am unable to delete the labels which have accumulated and been automatically recorded in the "Labels" folder.

How can I delete these numerous labels that are no longer linked to any bookmarks ?

Thank you for your responses and suggestions.

With reference to my question just posted, also now when I click on my Firefox browser, the Yahoo search engine seems to take over and it won't let me come out of it. Mark

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.

Since the 132.02 certain eBay items will not display its shipping info. Only on Firefox. Its not addon because I disabled all and I have the same addons installed on edge and all good there, I can see the shipping info on edge. And its only about 50% of the items which is weird. I have done the basic troubleshooting and I have to think it was this update. If you see the images attached Shipping values should be displayed. Some have a $ value some say +shipping, those are not displaying the value. Please help me figure this out as I use Firefox ALL day but if this continues I HAVE to switch. Ebay is my main source of income now.

The bookmarks on my taskbar are all of a sudden not showing up. I'm unable to drag them there like I used to. Also, the history and menu button on the upper right don't work now. I've restarted with no luck.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?
