On this page, Mozilla says that I can "Assign a website to a container, so that a specific website will always open in a specific container. This helps protect from accidents, stopping you from accidentally visiting a shopping site in your banking container, for example."

But under Settings > Container Tabs > Settings, I don't see that option anywhere.

I'm using Firefox on Ubuntu, Linux. Recently, when launching a webapp of mine on localhost (port 4200 for the record, but I don't think that's relevant to the issue), and opening it in Firefox, the browser asks me in what application I want to open the localhost link. I just want to open it as a webpage, but I am forced to type "http://localhost:<port>" rather than just "localhost:<port>". It's not a major problem, but it is inconvenient to have to type "http://" everytime I want to open a local webapp in a browser window. I've looked around in Settings, and I found that "localhost" is listed as a content type under "Applications", but I'm not able to tell Firefox to not open the content in an external app. Is there a way to resolve this?

all of a sudden the backround color for new tabs is black, I hate black. How do I make only the new tab backround white. It seems like every new version has different default values. Why is it not possible to allow users to try, then choose which new interface changes we want.

I had same extensions running with Firefox in Windows 10 and I installed them in Firefox in Windows 11 and the icons do not show up. I installed/uninstalled/turned off the extensions and reactivated them. Nothing works. The icons will not show up and with one of the password managers the icon needs to show so that you can click on it and activate it. Also Malwarebytes Browser guard has the same issues. None of these problems occurs in Microsoft Edge. Seems Firefox is not ready for Windows 11 and I will not be able to use it as just too much work to try and rectify these problems.

Is there a way to make Firefox Reader View adapt to or follow system day and dark mode?

For example, if I turn on system Dark Mode on my Mac, Firefox Reader's View automatically changes to Dark Mode as well. And vice versa to light-mode.

Time is passing, new versions releasing, but problem are same. Firefox 71 had a good looking colored cleartype. Fonts was clear and pretty. And new versions have a monochromatic cleartype, which makes fonts to look like sh1t. How to take back a colored cleartype? Just tell me, how. I tried many gfx.font_rendering.cleartype_params, but nothing is working.

Firefox's Profile Manager has always been in dark theme, which makes sense as my Windows theme preferences dictate that. However, once, I launched Firefox, which, as per preferences, asks which profile to use (i.e. Profile Manager), and the window is in light theme! I tried refreshing Firefox, and when that didn't work uninstalling Firefox along with user data and preferences (along with the "Old Firefox Data" folder on Desktop), but none of that made a difference. I restarted the computer, and that didn't nudge a thing either. What is happening?

Hello. I updated Firefox yesterday and I have 2 little problems:


1. Can't limit number of processes. Option in settings is missing. They are always about 8 FF processes, so it's hard to kill them quickly from task manager.


2. I use Win7 with classic theme, FF is set to use system theme, and userchorme.css is put in Firefox profile folder. I don't like new unreadable tab design and and modern designs at all. Also I like simple classic look. After last update my URL-toolbar and active tab starts to display white. They were correct colour before update.


I'm uploading screenshot and userchrome.css. Thank you in advance for your answers.

I currently have the latest version of Firefox which I recently changed to. On previous versions it used to be possible by changing certain settings in about:config to make Firefox keep history longer than the default. I searched "history" though and I can't find that particular setting. It's really important for my business that Firefox doesn't delete my history. My system is able to support a larger history file. Thanks.
