I got an email supposedly from breach-alerts@mozilla.com that claims there are currently 3 data breaches and has this link to resolve: https://blrv1ly5.r.us-west-2.awstrack.me/L0/https:%2F%2Fmonitor.mozilla.org%2Fuser%2Fdashboard%2Faction-needed%3Futm_source=monitor-product%26utm_medium=product-email%26utm_campaign=monthly-report-free-us-scan-no-exp-yes-breach-resolved-no%26utm_content=resolve-exposures-us/1/01010195ceba1024-6e3f74fe-119a-4e2e-9033-398671a830d9-000000/DDeGOTLjROOXCCk2fJvXJbdefc4=419

This seems like a phishing email, is it legit? Should I find another browser?

Bookmarks have been intermittently disappearing for weeks but I could always see the blue star when I visited favorite sites that I use upon starting my day that I had bookmarked. This morning all bookmarks were missing. I tried clearing cache which had worked to restore some bookmarks that were missing. Now everything is gone and I cannot recover them. There is an error that appears when I open Firefox re: bookmarks and I followed the steps but it did not work. I really need my bookmarks to do all the things I need to do, like everyone else, including medical information websites. I hope you all can get this figured out as it has been a problem for a month for me, on a PC. I know my favorites are stored somewhere on this computer but I cannot make them populate. If someone would like to take control of my computer and fix it for me, I would happy to let you do that. I have run sfc/scannow and chkdsk/f as well as a total virus scan with Norton. I have restarted my computer several times as well as done a complete shutdown several times.

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

W 11 May, 2025 update really made my computer unable to go online in any way and I had to restore. But FFox updates to have made it impossible to communicate. My phone has trouble s too. So, how do we make stick telephone permissions for, say: G Voice page https://voice.google.com/u/0/calls now? Thank you

Gmail is slower than frozen molasses, it is taking 15 to 20 seconds to respond to mouse clicks and typing as well as scrolling, it takes me more than half an hour to do what should take a few minutes, if this is not fixed soon that will be the end of Firefox for me, I will use Opera instead.

Hi i have lost my bookmarks, comes up Import bookmarks, my sync is on, I have gone through and checked library and there are no backups, restore? No idea why this happened, they all just disappeared? Any other advice to try please?

I don't know whether this happened after an update - there was one a few days ago, but I only realised this morning, after switching on the computer, that all my bookmarks are missing. The toolbar is there, empty, only reading "For quick access, place your bookmarks here on the bookmarks toolbar"... I wish! I tried to restore the bookmarks - but it seems there is no backup to restore at all. Then I tried to check my profiles, but there is only the one currently in use. Then I tried to move a tab to the bookmarks toolbar - and nothing happened. Then I began to panic: toolbar apart, we're speaking about years of bookmarks, most of them related to my research for my books... All the advice in the support seems to point towards profiles and backups, but, as I said, it's clearly not my case... Please, please, please: help!

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

Hello,

I dislike the Group Tabs feature. So many times I've accidentally created a Group Tab and then had to figure out how to un-group them.

I've tried to change the value of the "browser.tabs.groups.enabled" preference to false, but it doesn't stick; after restarting, the value is always back to "true".

What’s up with this?

Thanks, Andre’a

I mean, the tabs size are already bothersome that if you have multiple tabs open it's annoying you can't read the title of the page on that tab. So, you change it manually to size 200 instead of fabricated install as 76.

Who makes sure to change these to different size?

Tab width size config browser.tabs.tabMinWidth

Now, on the latest version, it shrinks on multiple tabs.

WHO IS AUTHORIZING THE RELEASES? I MEAN, DO YOU INTENSIONALLY MAKE ERRORS AND RELEASE THEM?

Firefox desktop on PC version: 136.0.0

I have some code in my .css file that had restored colored folders, a la pre version 89 AFAIR, for the folders on the bookmarks toolbar and in the bookmarks menus off the toolbar. It was working in V138.

I just upgraded to V139 and it's no longer working. I have the plain black/white wireframes back for the toolbar folders on the bookmarks menus.

The code I was using is below. I didn't write it and I confess that I only marginally understand it.

Can someone help me to regaining the colored folders? The white ones are a serious visual impairment for my brain. I need them to be more distinct from the menus themselves.

Hello all, I have the same exact problem described in post https://support.mozilla.org/en-US/questions/1463436, dated 9 December 2024. Until ten days ago (more or less) all was working correctly. At the beginning I thought there was a problem with Intesa because Intesa had problems in all the country in that period, but I have now tried CHROME and found that is working correctly. My system uses Firefox 139.0.1, W10-32 and Iliad FTTH. I have already cleaned cache and data from settings but the problem remains. Any thought? Thanks very much for any help. Mario.

i need to copy and paste text that's also a link, but firefox isn't letting me highlight it, I can do it in chrome, brave, & opera, it's not a mouse problem either, if I just right click on the page and select "highlight all" FF wont highlight it, is there a setting for this or a extension I can download? (in the picture the the rad text is also a link, I need to copy the number portion)

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

I have Firefox's New Tab set as my home page, since I'm choosing to divorce myself from political doomscrolling for the next four years. The New Tab page is perfect for having frequently visited sites at the top, Pocket stories I can curate in the middle, and what used to be a history of articles and sites I've read most recently in "Recent Activity" along the bottom. Within the last few days, "Recent Activity" has been blank, and will no longer keep track of articles I've recently read. I've tried clearing the browser history and cookies, and it came back for a moment, but quickly went back to being blank. And the major downside to clearing the browser is that my four rows of most frequently visited sites gets wiped clean also, and I have to spend time getting them back on the list. I do not have Firefox set to automatically clear history upon closing it. I've tried turning "Recent Activity" off and on with the page's Settings (cog in the bottom right corner). I'd really like to have this back, as it can help me find recently read content (especially Pocket content) easier than wading through the History log. Any help would be appreciated.

ATT.NET is blocking my access to ATT/Yahoo email from my ATT.net account using Firefox ''but not using Chrome?'' I have stopped all tracking and cookie blocking

"Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over."

Can you tell me the key(s) to open the AI Chatbot sidebar under Firefox Labs? (or implement one if you haven't) every time i hit the X to close it (as it takes up a lot of space) there is no easy way (that i can find) to reopen it without clicking through a bunch of stuff. Thanks!
