I would be grateful for some information on container behavior, i.e. I created "permanent" (as opposed to temporary) containers for sites where I want that site's cookies & site data preserved in a container, so I can click "Clear Cookies/History" (or "Clear... when Firefox closes) and the items stored in PERMANENT containers are left alone, while all else is deleted. "Clear ...." doesn't appear to be respecting the permanent containers I have set up precisely to preserve these sites' cookies & data.

I'm not sure what the point of Permanent Containers is, if not to preserve those sites' data, for the sites' later use when you set Firefox to Clear Cookies and Site Data whenever Firefox Closes (or Clear Cookies & Site Data with one click). I expected it to respect data in Permanent containers, as exceptions. Else why not just use separate Temporary Containers for everything? Why bother with Permanent Containers if everything is going to be deleted when Firefox closes, whether it's marked "Permanent" or not? Is there a solution for this? Thanks, -AnneF

Hello, using Windows Version 22H2 (Build 19045.5965), Firefox 139.0.4, Thunderbird 139.0.2, I can drag multiple emails from Thunderbird but not drop them into Firefox (the stop symbol appears and does not let me finish the action). However, dragging and dropping single emails does work. Firefox does not understand the imap address but the drop is registered which is all that is relevant to me. Is this a bug/missing feature in Firefox or a problem with Thunderbird and Firefox on Windows? Or is there a way to do it by simply adjusting (preferrably very few) settings? Dragging and dropping multiple emails using Thunderbird and Firefox on Linux Mint works fine. Dragging and dropping multiple emails from the Windows Explorer to Firefox also works fine. In testing, the issue only arose using Thunderbird + Firefox, Chromium-based browsers also worked fine with Thunderbird. If this is the wrong forum to ask such a question because this should rather be in a bug tracker or something similar, please let me know. If this should be on the Thunderbird thread instead of Firefox, also let me know. Thank you for your help.

We can't get into our gmail (3 accounts ) on 1 pc , but we can use a friends pc both using a firefox /windows v-11

People don't respond to Gmail requests, only computers with simple answers for simple inquires, HARD THINGS ARE TOO HARD FOR THEIR MAINFRAMES. THANKS

I have only one instance of Firefox to run.

How can I correct my installation so it does not think something else is running/updating Firefox?

Thanks,

Craig

I realize this is in a beta OS, but I imagine it'll need to be addressed at some point.

Anywho, when using vertical tabs, the left side expand/collapse button lives underneath the close, minimize, full-screen OS buttons.

If I turn on "always use private surfing", can I not have shortcuts on my Firefox landing page?

I had six shortcuts on my landing page; however, I turned on "always be incognito", and my shortcuts disappeared, and I do not see an option to add them back.

Are they mutually exclusive? If not, how do I FIX THIS?

I have three computers on a home network. All 3 have Firefox on Windows 11 Bookmarks on Two are in sync. The third will not. When I login it has my email and password but creates a new profile.

Every time the browser autofills a password it asks me for my Windows password. I don't want this behavior, as this makes password autofill completely pointless. How do I disable this "feature"?

I'm using Firefox-bin on Gentoo, wayland, and for a long time with all updates on my main firefox profile smooth scrolling can not be disabled: Both UI settings called "Use smooth scrolling" and manually setting general.smoothScroll on false - does nothing. Setting general.smoothScroll.mouseWheel on false actually disables smooth scrolling for mouse wheel, but smooth scrolling still happens on keyboard scrolling (holding up or down arrows).

On same browser I have two different profiles: On one of them smooth scrolling were disabled long ago On another one I successfully disabled smooth scrolling this day (it's some default one that I haven't used)

There are no extensions that could override this and I tried disabling them and rebooting and trying again too. I haven't touched any other scrolling relating options except enabled "autoscroll" and tried disabling apz.gtk.kinetic_scroll.enabled but it made no difference.

I found only few entries that describes same thing from long ago but they seem to not be applicable to this one. This bug is only mildly annoying because I rarely use keyboard scrolling and general.smoothScroll.mouseWheel = false already solved half of issue but I'm worried a little if something is wrong

I have not changed any settings related to fonts in firefox (running on windows 10 desktop), but I have this issue where flag emojis are displayed as a letter code on the page itself, but still display correctly in the tab at the top. is there a known fix for this?

I would like to know what happened to all of my bookmarks I had when I opened my firefox, nothing is there and I can't seem to find out how to restore them.. what ever you have done to firefox, mozilla I hate to say I don't like it at all.. thanks

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?
