Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

MY FF recently updated to version 1380.1 (64bits) and my Sidebar Bookmarks are gone. That is I have to manually put them back every time I now start FF. I want them to always show when I start FF. When I need extra screen space, I would click the X and they'd disappear for that session. And when I was done, I'd click on View - Bookmarks they'd be reinstalled. And when I shut FF down and returned later, they'd be right there where I need them.

My question is, how do I get back to that setup?

106.0.2 locks up Windows Explorer (Not Responding) on my Win 7 machine as soon as it starts. After restarting Explorer, it seems to continue working. I have seen this issue reported earlier.

Hello. Recently I've noticed video quality has been reduced on amazon prime video. I get a message saying my hardware doesn't meet HDCP requirements.

I've already tried playing the same video on edge, and the quality selector was fine there, full HD video.

Thank you in advance

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

I've added https://x.com as an exception site but it is still blocked.

This is outright censorship which is something [edited] do.

Tell me how to fix your browser so I may access x.com again or I stop using Firefox forever.

Sync just does NOT work. I installed FF on my Mac brand new and fresh... brand new machine. Signed into Sync. NOTHING. After 6-7 HOURS... nothing. It just gets NOTHING AT ALL from my Windows Desktop.

I've signed out of ALL Firefox/Mozilla sync sessions... signed in clean- all browsers are up to date. And the about:sync-log page shows a LONG streak of errors... NON STOP ERRORS.

Why?! Why can't we just sync extensions to install and bookmarks across machines? How is this that hard for Mozilla?!

Day after day and attempt after attempt of failures for a basic function of the browser.

Here is the text of the latest log and showing constant connection errors- mind you NOTHING is breaking on my internet as I'm often streaming things and watching stuff while surfing, or others in the house are. Our connection, and Firefox getting online, are all working fine. I am at a loss. I don't understand how this is so terribly broken out of the box that you can't just sign in and let it talk to their servers. I know Google has billions behind Chrome, but this shouldn't be so 1990's bad by comparison to Chrome sync.

Updated to esr 128.14 Now Reddit (Redgifs) Hosting site for gifs crashes Firefox and cripples my PC. I've tried restarting in safe mode, then refreshing Firefox. Nothing is working. Reddit support just has an issue with the Gifs not playing, but nothing as extreme as what iam experiencing. I believe it may be something is preferences or a codec or something that was changed in the recent update. Any advice/ help would be great. Edit: OS is windows 10 latest updates Amd- Ryzen 7/32gig 3.20 ghz PC. So can handle a little bit of heavy browsing.. FF 128.14 esr Ext- Ublock Origin

       Search By Image 
       Flash and Download Video. 

Even with Addons disabled still occurs. Really at a loss here.

How come FF translates sites in tiny, irrelevant languages like Bulgarian, but not from major languages like Chinese and Arabic?!?

I wish I could dump Edge, but this FF deficit forces me to keep Edge on my computer...

Majority of the songs do not play and I'm given with a pop-up, "Spotify can't play this right now. If you have the file on your computer you can import it."

I will play a song from a playlist and is given that pop-up, it will continue skipping to the next song until it plays, but only for 9-10 seconds until the song mutes, to specify, the dot (when hovered on the progress bar) will still move, indicating that "it's playing".

Some clarifications: 1. I use Spotify Desktop app (windows), Spotify App (android), and Spotify Webplayer on Chrome and Firefox. Everything works just as fine on all of these, except for Spotify Webplayer on Firefox. 2. Skipping to a later timestamp does not unmute the song. 2. I have Spotify Premium 3. I have no VPN 4. I am running Firefox with an ad blocker 5. I am running Chrome with an ad blocker (same ad blocker in Fifefox) 6. I am running Firefox to the latest version (Firefox 119.0.1 (20231106151204))

What I've done so far: 1. Cleared caches and data. 2. Updated my Windows to the latest update available - Win10 v.22H2 3. Signed-out of Spotify for all my devices, then logging-in first on Spotify Desktop (this automatically redirects to Firefox webplayer) 4. Ran Firefox on "Troubleshoot Mode" 5. Un-checked and re-checked "Play DRM content" setting. 6. Disabled and re-enabled the plug-in "Widevine Content Decryption Module by Google Inc". (this plug-in is last udpated on November 17, 4.10.2710.0

I'm including this link from Spotify's Community page.. where two other users, who commented it is only with Firefox (webplayer), are experiencing the same problem as I am. https://community.spotify.com/t5/Desktop-Windows/Spotify-can-t-play-this-right-now-If-you-have-the-file-on-your/m-p/5679914#M123192

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.

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.

This morning I went to check my email on gmail, and google asked me to sign in again. Easy, I thought. I entered my account, and then google asked for my passkey. Until this morning this meant that on my mac it would ask me to place my finger on the right key on the keyboard. This morning it just froze firefox indefinitely. I then tried on Safari, and it worked as expected. I checked the version of firefox: it's 136.0.1. Obviously something changed (i.e. broke!) with the new version. Has anybody else experienced this? Any suggested fixes?

Co to są witryny z ograniczeniami, co to są strony ograniczone przez Mozillę, o czym mowa na stronie https://support.mozilla.org/pl/kb/dlaczego-niektore-dodatki-nie-sa-dozwolne-na-stronach-ograniczonych-przez-mozille?as=u&utm_source=inproduct#firefox:win10:fx135 ?

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?

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.

I had to actually sign up fort a Mozilla account,the multiple hoops I had to jump through were ridicules, in order to ask a question of Firefox. I do not want my address bar to be my search engine. How do I disable the search engine in my address bar? And now I have to wait for an answer!!!!!!!! I used to love and trust Firefox. Not anymore.
