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.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

Let’s come together, share tips, and ensure we’re all prepared. Drop your questions or insights below!

I have used Firefox for longer than I care to remember and have never had any problem with it but this morning I switched on my PC and a new AI side bar has appeard on the left and I don't want it. Can you please make it so we can remove it and looking around the internet, I know I'm not the only one with this opinion.

A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

Today I Receive Mozilla Firefox 133(64Bit) Update. After Successful Update. My Open Tabs Are Not Loading. Also, Firefox Become Very Slow When I Surf Youtube Videos. Video Stuck But I Can Hear Audio. Taking Time To Load Videos. Its A Portable Version.

I cannot print anything on my computer since this PDF Print appeared. Everything was going along as per normal, now this. How do I get it back to the "normal" situation for me. Receive an email, hit the print button and lo and behold a printed sheet, etc. It is driving me to distraction. I have been using FireFox since whenever, no problems. I'm not too computer savvy but enjoy its use like anyone else. Something I will be able to follow and implement. I have seen a delete article but couldn't get it to do anything for. I just want to delete it. I cannot even print a normal letter I have written. Than kyou most sincerelyTimothy Barclay teejay1949@gmail.com

Since version 122 there is a problem with installing the Szafir SDK Web extension. It is necessary to be able to submit signatures online. After installing version 121, I was able to add the extension. After updating Firefox to version 130, the Szafir SDK Web extension still works, wich is good. The problem is that not everyone will handle it this way.

I tried adding the extension manually, but the same message is always returned. "The add-on cannot be installed because it appears corrupted."

Is there any solution to this problem?

Tenable is reporting 128.1 and 128.2 as affected by vulnerabilities covered in CVEs' in their plugin 205009 ( https://www.tenable.com/plugins/nessus/205009 ). The rule they are applying is: Mozilla Firefox < 129 That implies that 128.1 and 128.2 are also < then 129 -> therefor vulnerable. Can you please answer 2 questions:

• are Firefox 128.1 and 128.2 part of the same branch of product as 129? Or are they necessarily ESR?
• are Firefox 128.1 and 128.2 affected by CVEs' covered in their TENABLE plugin 205009?

The most recent update to Firefox, on each of our four Windows 10 systems, has a new glitch when printing PDF files. The particular files we're trying to print are in LEGAL SIZE format, and Firefox is compressing the text into a size that only uses half the page. This is true whether or not we select LEGAL SIZE in the printing interface, and regardless of the "Scale" setting. We had to switch over to printing these files with Adobe Acrobat, which worked fine.

Hi ! I'm a long term user of the "Firefox" browser. My Firefox User Nº is : 14634487 I'm also an existing long term user of both "NordVPN" and "NordPass".

When logging in to "Nordpass" this morning on my (new) MacBook Pro, I received a message in the App window stating that they were "ending support for my extension on 30th of September" and inviting me to "get the latest extension to continue using NordPass in a browser"

So, I bought a 2 year subscription for the extension 'NordPass Premium for Firefox'. Nordpass has acknowledged this by email: Quote : "Thank you for your purchase Here are the details of your order. Item  : NordPass: 2-year subscription Price : £29.43/2 years VAT 20% - £5.89 Total: £35.32/2 years"

In a 'Welcome' email sent by NordPass, I clicked on "Download NordPass which opened a Firefox 'Add-Ons' web-page for downloading the app named "NordPass Password Manager and Digital Vault" - but the only functioning button was 'REMOVE' ! I tried to 'Log In' at the top right corner of the page but I then became stuck in a continuous loop of picture identifications to prove I was not a robot ! It just went on and on ! I abandoned it for a while and, when I returned, the 'Robot check was gone but all my attempts to get the extension have failed ! I can't for the life of me find ANY means of downloading and installing the extension I've PAID FOR !

Whether this is all owing to a fault on the "NordPass" side or in the "Firefox" browser side is a mystery to me. Either way, I'm sending this message to BOTH.

I've now given up trying to do it unaided. PLEASE, could someone advise me how I can get my extension !! If this isn't resolved quickly, I'll seek to have a refund of my £35.32 and will have seriously to consider leaving both "NordVPN" and "NordPass" and/or defecting from "Firefox" to the "Safari" browser.

I'm waiting eagerly to get this sorted. Regards, Ivor Mitackis

I cannot open firefox. The error box says that the platform version 130.0.1 is not compatible with the maxversion 130.0 or the minversion 130.0. It looks as if the upgrade to 130.0.1 was incomplete. I need to have this fixed

Every time I open Firefox recently, and the Yahoo.com web page starts up, I get an annoying prompt from global privacy control, that asks to allow or not allow. IT'S ANNOYING. I went into the settings for that apparent add on feature, that I DIDN'T add, and set all 5 settings to FALSE, but the program still pops up. It ALSO screws up the format of the Firefox web page, and shows the Yahoo News feed totally different and it's also VERY ANNOYING HOW do I totally get rid of the global privacy control? I can select the Firefox settings under security to tell web pages to not sell the info, as far as I know, correct, so I don't need the retarded global add on? ?? I want Firefox news feed like it was before the update. Thank you very much... HOPEFULLY!
