Diễn đàn hỗ trợ Firefox

Hi,

How can I force Nightly to play a media type ? Per instance, the top main video here : https://www.lapresse.ca/international/asie-et-oceanie/2025-12-23/coree-du-nord/kim-jong-un-inaugure-un-complexe-hotelier-dans-une-station-de-montagne.php

Best regards iBenny

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

Since the last update, Gmail has not been working correctly on Firefox. All of the buttons to the left of inbox emails that enable you to move, categorize, file, etc your emails have disappeared. I have tested my Gmail account on Chrome, Edge and DuckDuckGo browsers, and everything displays correctly. Please help. An image of the missing buttons is attached (well, since there aren't there, you're seeing a blank area of gray to the immediate left of my inbox [or any other folder] emails). Many thanks -- this is driving me crazy. P Haynes

Firefox crashes whenever my computer goes to sleep. I am running windows 11 and have been for years. This problem showed up a few months ago. The crash then screws up other apps and I have to restart my computer to fix it.

I come, trying to manage my disappointment and anger, to say only one thing: I love Firefox, it (still) has the best UX of any modern browser. And part of that is that it has NO AI malware built into it. The recent statements from the CEO regarding the implementation of AI into the browser is extremely disappointing, to the point of it feeling like a personal betrayal, and will only make me (and a lot of other people) just completely abandon it. And don't kid yourselves, your user base never was so low, and that user base only like this browser specifically because it has no malware built into it, because of the privacy and open nature you had before this debacle. You're shooting yourselves on booth feet and an arm with a shotgun. I don't trust you as a company anymore at all; you just achieved the complete opposite of what you said you wanted. If you just made use of reverse psychology and was that's your actual goal, congrats. This company quite literally couldn't have elected a worse person to be chief executive.

Desktop Firefox 142.0.1 (aarch64) iPhone 11, iOS 18.5, Firefox 144.1 (62735)

I just reinstalled the desktop which needs the mobile phone's bookmarks. If I wipe the phone bookmarks, I lose everything. Backup, how on the phone? Sync, how? The Firefox Bookmarks Sync isn't an exact science and a misstep could be catastrophic!

Here's what I'm looking at on the desktop and the phone, attached. 1. Desktop Firefox Bookmarks Sync window show a 3 horizontal lines (hamburger icon) for iOS Firefox settings. 2. Phone Firefox has 3 horizontal dots (meatballs icon) for iOS Firefox 3. Phone Firefox has my Firefox account logged in and a Settings option, but which one (I choose Settings 4. Phone Firefox Settings shows my ACCOUNT and a Sync Now option, but which one (I don't want the phone to Sync and pull no data from the desktop and wipe the phone Bookmarks (no backups)).

Hello,

I have three devices: a desktop and a laptop with Windows 10, and another laptop with Ubuntu (LINUX).

I read that I can purchase a VPN installation. Do I need to buy three separate VPN installations or one with a single login and password?

Thanks, Pavel

My friend recommended this browser to me. When I tried to customize it, I couldn't find an option to change the hotkeys to my preference. I consider this feature important since I use it for work. Can I do this somehow, and is there any plan to add such a feature to the settings?

Hi there!

I'm a long time user of Firefox, on and off since roughly 2004.

I just saw the Mozilla blog post about Anthony Enzor-Demeo taking over as Mozilla's CEO this morning and am writing here in an attempt to find a way to reach out to anyone within the Mozilla Foundation regarding the direction the Firefox application has been headed, and try to make myself and similar minds within the Firefox community heard about the changes that Mozilla has made to its policies and direction.

In February 27th of this year, Mozilla changed Firefox's ToS and Privacy Notices to incorporate legally binding policies for the application and strip it of its original privacy-first, open-source nature. This, while not a deterministic factor in how the application operates; illustrates a sudden, outward and hostile stance towards its existing user-base who is most commonly comprised of users dissatisfied with the lack of secure and private browser options available. Personally, I refuse to use Chromium-based web engines wherever possible and Firefox has been my one and only way to break from this "monopoly" of web engines.

Beginning to harvest user data for use by Mozilla and claiming ownership of any user content is immediately a massive breach of trust and contradicts what Mozilla as an organization has stood for since its inception. Going a step further to utilize this data to either be sold to advertisers as an asset, or to be used to train LLM's is exactly what I DON'T want to have happen with my data. I hate that this change happened and it massively reduced my trust in Mozilla and Firefox as a platform.

I never asked for this, Mozilla promised that it would never happen, and now I'm left betrayed by broken promises made with the express intent to turn a profit on my behalf as a user.

In Anthony's blog post, he mentions how AI has reshaped how people search, shop and make decisions in ways that were hard to see or understand. I outwardly disagree with this statement and feel as though AI has "infected" its way through society by brute force, being put in front of every user and shoved in every application. LLM's are not a catchall solution, do not help resolve issues in new and innovative ways, and are massively misused, causing excessive resource usage, gutting consumer markets, and decimating the tech industry by causing excessive amounts of data centers and global tech inventories to be purchased and built with no promise of delivery.

While I may want a fast, modern browser that is honest about what it does- I want that with no obscurity. I want a web engine that is open source, as lightweight and minimal in its design and coding as possible; and with no bureaucracy. I want to know how the engine works, to have the option to review its codebase front to back, to have my data stay as my data on my own local machine without providing it to a third party simply by using an application. Mozilla with its changes since February of this year have removed this as a possibility from their entire application suite.

I don't want AI in my browser- AT ALL. I have disabled it in every capacity that I can (frustratingly too, as these are all enabled by default and FORCE me to provide you my data without express consent.) and with every advancement Mozilla makes towards calling it "the future" and "the focal point", I lose trust. I don't want AI, I want the old privacy policy put back, and I really, well and truly and wholly, DO NOT WANT AI.

I NEVER ASKED FOR THIS, IT'S RUINING OUR LIVES, OUR SOCIETY, OUR PLANET, AND I WANT IT GONE.

Unless Mozilla stops this direction today, I will be seeking out new options, disallowing Firefox usage in any corporate environments within my jurisdiction, and actively informing friends, family and acquaintances of Mozilla and Firefox's fall from grace, and to utilize other user-centric options.

Thank you for your attention, have a great day, and I hope Mozilla can create action that will allow its users to trust it once again.

Saying "you can turn off the AI" is NOT enough, Mozilla. Nothing is ever "turned off" unless it's completely removed. This is Microsoft's playbook BS; "but you can turn it off", but for some reason the system is always using a metric ton of memory, lagging and whatnot. You, of all companies, should know this and be better than that. Nothing good is ever force-installed and impossible to remove. Unless you all make it installed completely separately so people like me, who are a significant part, if not most of your user base, can not install it, nothing short of a full renunciation of the CEO will suffice to make we trust you again.

"Internet for People, not profit" is seeming more and more like blatant false advertising every day.

For some days now the Guardian (UK journal) website can't be loaded. It's specific for Guardian, I have no such problems with other sites, and I don't have this problem with Guardian with Chrome. I've erased cookies and caches, restarted my computer, to no avail. I'm using version 146.6.0 of Firefox on MacBook Pro 2020 with Sequoia 15.7.1.
