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!

Machine: Dell Inspiron 15 5567 CPU: Intel i5-7xxx Op Sys: Ubuntu 24.04.1 Firefox version: Flathub 130.0

For the past 2 weeks Firefox has been repeatedly crashing soon after going on to certain sites or trying to apply my 2FA authenticator add-on.

Suddenly there's a screen shudder and a new window opens, inviting me to submit a crash report. See attached image.

I do not believe that this is down to Ubuntu 24.04 upgrade done at end of August.

But it's enough for me to largely go over to Chromium and Firefox Dev Ed.

If Mozilla don't act on this crashing I can see its market being lost fairly fast.

I keep experiencing this problem with different websites: Safari works, Firefox doesn't.

Sample: I turned out the enhanced tracking protection, Privacy is set to Standard for

https://search.ccb.state.or.us/search/default.aspx

I entered valid license numbers (230880, 239798). Firefox displays NOTHING, no error message. Safari displays the relevant info.

Why is this and what should I do if I want to continue using Firefox? Thanks.

Today I was no longer able to stream movies on Amazon Prime or Youtube. I watch Amazon movies most nights, watched last night. Tonight I got a message when I tried to continue watching a tv series on Amazon that I've watched for weeks. It said I had to update Firefox and told me how, but when I went thru the process Firefox said it was up to date. On Youtube I got an error msg. 99,999 . What is happening?

I want to delete all my bookmarks at once -- I have nearly 1,500. I already asked this question and the response I got showed me how to do this by selecting each one at a time. I want to delete them all, AT ONCE!

Not selecting each one and holding down the CTRL key.

Btw, I already explained this ... so, is there a way. I've tried uninstalling and reinstalling and not keeping the former settings. But the stupid bookmarks keep coming back!

the past 4 producers have told me they cant hear me on google video chat (https://meet.google.com/) i'm on firefox. it worked fine forever, then no one could hear me and i reported it a bunch to google and firefox because it was clearly a firefox issue. someone on their end fixed it. it was working for a while. now its back to people not being able to hear me again when its not a me problem. i keep reporting it and its not being fixed. how do i escalate this? why does this keep having every few months?

zero issues on google chrome browser while video chatting. zero issues on zoom. its firefox's google videochat that people cant hear me. feels like a repeat issue of what happened months ago when the issue wasnt with me. please fix this again

My page throws errors in Firefox Nightly such as

Expected color but found ‘undefined’. Error in parsing value for ‘background-color’. Declaration dropped. preview.htm:1:1

and

Expected color but found ‘undefined’. Error in parsing value for ‘color’. Declaration dropped. preview.htm:1:1

The page references ten CSS files besides having dozens of its own CSS declarations. The issue is tha the reference provided to the error (:1:1) does not indicate where I can find the error. That is, I don't know which declaration is at fault. Is there some straighforward way to find the declaration in question?

I've asked about this before but got no help Firefox is my browser of choice. Occasionally, I find in necessary to use Chrome.

The vast majority of time, when are both are active at the same time, one or both crash, like today. Firefox closed abruptly, then the crash report appeared. I have the crash report. Chrome froze up, and had to be shut down in Task Manager.

It only occurs in this scenario. Rarely does Firefox crash otherwise.

Can someone please advise where to go to get help?

Yet another sterling example of why change is usually bad. Why did Firefox, Google and other browsers (though don't know about Duck Duck Go) drop the 100 results per page option? I've always had that enabled and now that it was removed it makes searching extremely tedious and time wasting. Please offer a SIMPLE AND QUICK way to restore this option ASAP. Thank you.

I can login to B of A and do everything except reach the make payment page on my PC desktop. I've cleared cache and cookies per B of A instructions but it doesn't help. I can get there on my iPad's Firefox, however. They said to contact you.

As of last week, FF works for a few minutes on startup, but then when you open a new tab and try to go to a site you just get the dancing period, nothing opens. Already open tabs with sites generally still work, but sometimes crash the tabs after a bit. We've tried starting without extensions, uninstalling and reinstalling FF, changing the profile, logging in the PC (Win 10, up to date) with a different login, running SFC and DISM on the PC, and just about everything else.

Opening the FF console shows this message when the tab just rocks the period:

WindowsJumpLists: Failed to fetch favicon for https://online.adp.com/signin/v1/?APPID=WFNPortal&productId=80e309c3-7085-bae1-e053-3505430b5495&returnURL=https://workforcenow.adp.com/&callingAppId=WFN&TARGET=-SM-https://workforcenow.adp.com/theme/admin.html NS_ERROR_FAILURE: WindowsJumpLists.sys.mjs:257:29

Edge works perfectly (and unfortunately, I'm having to use Edge to enter this ticket.). Other applications don't have any issues. I'm not having this issue on 2 other similar PCs I have that run FF, only this one.

Any ideas of what might be the issue with FF on this PC? Thanks, Alex

This video file cannot be played.(Error Code: 102630). - This is the error i get when i try to play this movie .

Context : - I upgraded to the latest version of firefox and i also connected my dns to nextdns recently. - I use arch linux and firefox on linux. - Previously all the videos on the site were playing nicely but now it has started showing this error. - I have tried many solutions such as :- 1. Clearing cookies, cache,etc and refreshing firefox . 2. Installing media codecs onto my pc using console. 3. Deactivating the dns and disabling hardware acceleration. 4. Restarting my pc but nothing works.

I was wondering if someone has a solution to this.

Firefox is blocked by some websites, saying it is a bot, have you had this happen?

You have been blocked. Why? Something about the behaviour of the browser has caught our attention.

There are various possible explanations for this:

   You are browsing and clicking at a speed much faster than expected of a human being.
   Something is preventing JavaScript from working on your computer.
   There is a robot on the same network (IP XXX.XX.X.XXX) as you.

A while back I noticed that my google calendar no longer sends reminders to my gmail (or rather, I suspect, gmail does not receive them). Yesterday I missed an important meeting because of this, so I want to get to the bottom of it. I verified that the reminders are properly set in my calendar, so I have to assume that they are going out. The pop-up windows do pop, so I assume that it is not on the calendar side. I also noted that calendar.google.com and gmail.google.com have the proper permissions to send pop-ups and notifications to gmail, which indicates to me that this end of the equation is working. (Don't know how to isolate the error further, though.) It seems that the Firefox settings need to be changed somehow. Any ideas?

Thank you!

Hello everyone,

I’m reaching out because I have some concerns regarding Norton’s HTTPS scanning feature. Recently, I noticed that Norton scans HTTPS traffic, and I’m unsure about how this impacts my privacy and security. While I understand the feature is meant to detect threats, I’m particularly worried because it involves decrypting sensitive information. This raises concerns about whether my personal data, such as login credentials or payment details, could be exposed during the scanning process. Has anyone else experienced issues or found this feature problematic? I'd love to hear about your experiences and whether there are any steps I can take to ensure my online security without risking privacy.

I also have found a names of site that were blocked in the report generated from Norton

Hi all I like to show the bookmark toolbar in fullscreen mode. I have enabled "show always" but it does not show in fullscreen mode. On old firefox versions i could create a userChrome.css file and then it worked. But it looks like this is not possible with never (130.0.1 ATM) versions. May be the code has changed? This was my "old" css code wich is still working with firefox-esr: /*

  Override hiding of Bookmarks Toolbar in F11 full screen
  when you roll down the tabs/main toolbar 

• /

1. navigator-toolbox[inFullscreen="true"] #PersonalToolbar {

 visibility: unset !important;

}

Hint: toolkit.legacyUserProfileCustomizations.stylesheets is set to true.

Maybe someone has a solution how to show bookmars in fullscreen.

Certain websites I visit will fail to display custom fonts, unless I clear cookies, where it works fine until I refresh the page, either by signing back in, or reloading. the screenshots I have are of https://developer.android.com/studio/install this is one of the sites that gives me the issue. I have tried disabling all of my extensions, and it still doesn't fix the issue. Any help would be appreciated.

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;

}`
