I have received today 16/10/2026 an email purporting to be from Firefox telling me that my account will be terminated in 7 days and account totally deleted. I'm not sure it's genuine as I use Firefox regularly as my main server. If it is correct can you indicate how I maintain my access to the web and my Firefox account please? "Message: Your Mozilla account and data will be deleted in 7 days Your Mozilla account is used to access free privacy and browsing products like Firefox sync, Mozilla Monitor, Firefox Relay, and MDN. Your account and your personal data will be permanently deleted on Friday, Oct 23, 2026 because you haven’t been active". Roberto Franceschini vespasianimp@yahoo.co.uk

Firefox repeatedly displays the same permission popup on a lot of website and tabs and especially when I open,ChatGPT. Even after I check “Remember this decision” and select Allow or Block, it keeps returning. I already changed the permission settings, but that didn’t fix it. How do I permanently stop this popup and make Firefox save my choice?

I'm on desktop. I clicked on what turned out to be a YouTube mobile link and now my Firefox desktop browser will only load the mobile version of YouTube. I tried several standard troubleshooting steps, including clearing history, cookies, and site data, disabling all extensions, and checking about:config for a user-agent override, none of which resolved the issue. YouTube has loaded correctly in a private window. It also loads correctly when I created a new firefox profile. I'm assuming the original profile is corrupted in some way. Is this the correct answer? Is there any way to fix it?

Currently I am trying to use the firefox built in VPN option. When I hit the turn on it turns on and goes green but I am unable to browse. I suspect this is due to the corporate firewall and content filters that are in place when I am in the office. The firewall team is looking for support as we are unable to find out what access is needed to be open for this service to work. What IP's does the service connect to for access? What ports are use for setting up that browser level VPN? Is their any application or urls that should be allowed? If documentation for what access is needed to be opened on a corporate firewall would be appreciated. We have searched extensively and cannot find the information other than this runs by Fastly. We cannot find ports/urls/ips that are needed.

Thanks Chris.

Hello,

my firefox browser is registered to my old email address "mhesky@hotmail.de". Because of an hacker attack i had to delete this email address. My new email address is "Hesky85@outlook.de".

My problem is, that i cant change the email in firefox because a confirmation email will send to my old email address that doesent exist any more.

How can i change the firefox account to my new email address?

I need help please.

At first deployment of multiple profiles in early 2026, my use was really intuitive and I was able to understand the FAQ and Community notes. Early October, the releases started to implement some refinements. I am not understanding these refinements and while I am seeing the error message (attached), I am not understanding what the fix is to use my additional profiles (two), int the past month, I have not found a way to get to my two additional profiles.

My environment: Windows 11 Pro - Firefox 158.0 (64 bit) I have Profiles "Original" and two others. I have one single Mozilla account. I copied my two profiles from original and had made great progress culling the profile passwords and bookmarks, I have only been syncing my original profile two my two cellphones. 95% of my use is from desktop Firefox.

Attached is a well documented result error but I am not locating how to get to the profiles I had created from the attached error message.

Hi. My Macbook Air (M1, 2020) has been performing slowly in recent days. I'm not playing video games or watching videos, just mostly working on many tabs in Firefox (157.0.1). I looked in my Mac's Activity Monitor, which shows that Firefox GPU Helper is using about 5.75 GB of memory. The next few highest users say "Firefox Isolated Web Content." Could any of these be what is slowing my Mac down? I'll attach a screenshot of my Activity Monitor. I also clicked "Share Data" below. I would say that my Macbook is working at a fine speed at the moment, so perhaps the screenshot and data are not so helpful. Let me know if I can add something later in a reply, when my Mac is moving slowly, that would be helpful. Thanks.

I am currently doing research on natural health supplements like astaxanthin (astadaily.com) and saving multiple articles daily. Are there any recommended Firefox browser extensions or built-in tools that help organize research notes and bookmarked pages efficiently? Any suggestions would be appreciated.

I wish FF would test and step through their instructions first. The instructions for Ad Blocker: " Settings > Browsing > Ad Blocker" It isn't as easy as they instruct: "How it works: Ad Blocker uses Apple’s WebKit Content Blocker technology and the EasyList filter list to determine what gets blocked. There’s no separate extension to install, and you can turn it on." Search settings unable to find Ad Blocker. Yes, FF browser is up to date.! FF expends a lot of verbiage to promote a new feature yet so slim on step by step instructions.

Hello. I am using Firefox on both Windows 10 and MX Linux, and I noticed a difference in how the New Tab page displays shortcuts. Even though both browsers are set to display 2 Rows in the Home settings, Firefox on Windows displays 10 shortcuts per row (20 in total), whereas Firefox on MX Linux only displays 8 shortcuts per row (16 in total), details in attached screenshots. Could someone explains why there are differents like that? Was it because the different between OS or Firefox versions (both was updated to lastest version)? Thank you.

Amazon prime video won't fully load. I've tried everything, shutting off everything, dumping the cache. It fully loads on chrome. This is new since the latest firefox update... what is happening?

this issue started when firefox just randomly reset my browser a week ago.

whenever i open a pdf in my file explorer, it opens a completely new firefox window under my default-profile. it doesn't open on my currently open/used window.

for context: i have two firefox profiles, 1 for work, and 1 is the default-profile which is "personal"

anyone know a possible solution to this? or why this happened?
