Diễn đàn hỗ trợ Firefox

I am attempting to locate the "manage containers" option on the container drop down menu but it is not there. I have read several other threads and have tried cntrl+ about:config "which did not have a false option" clicking right, and then maybe left and every which way I could click, but nothing. The drop down menu does not move so as to reposition and possibly find what I can't find. I do have my scaling pretty high, I wonder if that could be the problem. Any help would be appreciated, you know how we like to change these kinds of options.

I am the developer of FastF1, an open source Python package for downloading and analyzing Formula 1 race results, timing data and telemetry. The package is widely used in the fan community for independent analysis of results. For some advanced features, the addon requires users to authenticate with their Formula1/F1TV account. Since their services don't have an open login API, a companion addon is required to allow users to sign in using their browser and the official website.

I have just noticed that my developer account has been banned and the addon was blocked in Firefox. I have not received any email about this and don't know why exactly this decision was made. I'd like appeal this and reinstate my account and the addon, but I don't know how to proceed from here.

FastF1 and the companion addon are fully open source and intend no harm to users. https://github.com/theOehrly/Fast-F1 https://github.com/theOehrly/fastf1-companion

I hope this problem can be resolved.

I seem to have been using Firefox for so long, that I’ve forgotten some of the basics. I have two Apple systems. An M1, 2020 MacBook Pro and an Intel Mac Mini. Due to issues with the MacBook Pro I needed to reformat it and am slowly adding all my applications. When I added Firefox, logged in and entered the confirmation code and synced my settings none of my extensions appeared in the menu bar (please see the screenshot as to how they appear on the Mac Mini). So the question I have is what do I need to do to get them there on the MacBook Pro.

When I went to https://www.mozilla.org/en-US/products/vpn/ and decided to purchase a Mozilla VPN prepaid annual subscription part of the reason was this "feature"

"Easy Firefox integration with the Mozilla VPN extension (Windows only)"

There is nothing easy when clicking on the download for the Mozilla VPN extension yields a message that the add-on or extension has been blocked. The explanatory link provided is https://support.mozilla.org/en-US/kb/add-ons-cause-issues-are-on-blocklist. That lets you know that:

"When add-ons violate Mozilla’s policies, compromise user safety or privacy, or fail to meet user expectations, Mozilla takes action. This may include disabling add-ons in Firefox to maintain a secure and reliable user experience. "

So, when will Mozilla stop violating Mozilla's policies so that the Mozilla VPN add-on is fit for use on Firefox v 149.0 [without free VPN] running on WIN10 64?

Why are you trying to chase people away, after update i had to reinstall it cause nothing functioned right, now I have to jump through hoops just to install ad Guard. It should not be this difficult to use a website. I think I will move over to chrome where they actually try to make life easier and not more difficult

Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

I've been using alt+a to open new tabs in a multi account container for a long time. Recently that shortcut stopped working possibly with the update to v148 as indicated in this reddit thread.

alt+a is not listed as a shortcut in about:keyboard or in about:addons > manage extension shortcuts or in my ubuntu shortcuts nor in any software I can think of thats running. I've disabled all add-ons except multi account containers and it still does not work. Changing the shortcut to another works fine.

Why would just that shortcut stop working? What else can I do to diagnose the problem?

On Firefox version 140.8 using a MacBook Air, shortcuts for Extensions no longer appear as icons in the toolbar.

Online guidance to get Extension icons back in the Toolbar have failed. One suggested following the jigsaw icon in the toolbar to 'Extensions'. But none of the links under Extensions included the option to 'pin to the toolbar'. Another suggested using the 'Customizing the Toolbar' route. That too included no option to add Extensions.

Anyone know a better fix? Your suggestions are much appreciated!

Hello, Mozilla. I really appreciate the way you think about internet access. What you stated about the app is truly reflected within it: fast connections, accurate results, and most importantly, the security. However, when it comes to advertisements, I was really expecting that whenever I watch YouTube contents, there will be no ads shown. To my surprise, ads are still there. I provided a snapshot of my desktop to give a proof about this. Is there somehow a way to get rid of them, like perhaps an extension to block ads? If there's none, that's fine as well. Thank you and high praise to the developers of this browser.

I have just downloaded NordPass Password Manager. I think I have added an extension for this in Firefox, but I can't tell if it has been successfully added.

I am using Windows 11 Home Version 25H2 OS Build 26200.8037 64 bit operating system

Why has Video Download Helper v9 by Michel Guteriezze been replaced by Video Download Helper by vdh? The original versions were perfect. The VDH version 10 vdh is straight junk!

I don't plan to use any provided AI chatbot. I want to use models that I have downloaded and tested myself and which run on my PC. So please add the possibility to connect through major LLM APIs, the same way other tools way simpler than Firefox already allow to do.

I PAID for "dark reader" I got the activation key but I cannot activate it because the instructions says go to "MORE" and there is NO "MORE"! I hunted all over the settings & extension & themes, but I cannot find anyplace to activate this extension. Did I just waste my money? I have poor vision, I NEED a dark page with white letters. Thanks to being a touch typist, I don't need to see the keybord or page to type but i can't see what I am typing on a dam w hite page! I now cannot click on "Email me when someone answers the threadil"

I have just had to replace my PC following a bit of a disaster with my old one. The new PC has Windows 11. As usual I downloaded Firefox as I always use this. Somewhere in the installation of Firefox I must have been asked about blocking ads, but I don't remember. Now all ads are blocked, which I don't mind, but some sites are asking me to disable my ad-blocker if I want to use their site. Mostly I don't but there is one I need to use, so I would like to add that site as an exception, but I cannot find any mention of any ad-blocker in settings. Where do I find this? and how do I add exceptions?

The only add-on that I have in Firefox is the 'Privacy Badger' which could be the problem I suppose, but I can't see the website listed in the ones Privacy Badger is blocking.

Any help would be appreciated
