Mozilla Firewall was running with no issues on my Win11 v25H2 laptop until about a week ago. Since then, the program won't open. I've tried launching it from the install directory as admin, or from the Mozilla browser extension. The Waterfox Mozilla Firewall extension (v1.35.0) opens, but there's no response when I select "Open Mozilla Firewall."

One note is Mozilla Firewall is listed as a Task Manager Process. I ended all instances, but no change.

I've also: Uninstalled Mozilla VPN and deleted the install directory. Downloaded a new executable file and installed. Restarted and powered off the laptop. Windows Updates are current. Checked Event Viewer for Mozilla Firewall errors, but none listed.

Thanks, Ben

I'm talking about Firefox version 156.0 (64-bit)??? So since the last Windows 10 security update Firefox just wouldn't start anymore. I had two or three automatic refreshments of Firefox but even that didn't do the trick anymore in the end. Then there was a secundary Windows 10 update and I got everything running smoothly again for two days, and now today there was a Firefox update and the whole trouble started again. Even some sites wouldn't work anymore (outlook, DeepL) or I couldn't login anymore. I'll try going back to a previous version ...

Running Win10, all the sudden I'm getting Not Responding messages, failures to connect to server, and slow deleting of emails. I tried everything: uninstalling/reinstalling; running on troubleshooting mode; checking compatibility. Nothing works. Any ideas?

Thank you

I'm trying to use the Mozilla VPN I have on my desktop (hardwired) as a mobile hotspot for my LG Smart TV. I doesn't seem to be working the way I thought it should. Please can you give me any pointers on getting it working.

I get this dozens of times in a session. As far as I can tell it doesn't affect performance. I found a solution about using notification-daemon for Ubuntu from 4 years ago that doesn't apply to Slackware. I like to eliminate error reports. I don't even know what this means. Knowing would be great, even if I can't stop it. Just eliminating the error report, if it's harmless, would be nice.

I use Marblism for my business. With one bot the connection is fine, but I cannot connect one of the other bots anymore. Marblism support says they use Nylas for the IMAP connection, but have not been helpful beyond that. Thank you for any help :)

I posted a question on this forum that I want to delete. I can't find a way to do that. Is there some way to do it? This question isn't really about performance" of T-bird, but about this forum but I was required to make a selection. . . ..

Hi, I can't change the location from recommended in the Android built in VPN. When I press on location or recommended nothing happens. Any help appreciated

Sorry to keep reposting but it keeps getting put in the desktop forum even through I select the Android forum!

I have a windows 7 operating system running Firefox v115.40.0esr and the program runs but I am continually getting the error: The procedure entry point GetSystemTimePreciseAsFileTime could not be located in the dynamic link library KERNEL32.dll Is there a fix for this?

Whenever I make a video fullscreen like on youtube, then press Ctrl + N for new window, the new window appears without the windows taskbar. This happened after the last update. So, now there's a gap at the bottom where the taskbar should be, exposing the bottom portion of the video underneath .

Longtime Firefox user, Lenovo desktop, Windows 10 user, have Firefox version 154. Can log into my microsoft M365 account, but whan I click on "Search", my files do not appear. Box appears saying "No Recent Items" in place of my list of files.

Can this be fixed at Firefox??? I'm forced to us Chrome, which I do not want to do. Thank you. Mike Manning Text [redacted phone# and email from community support forum]

1. Emails won't open to be able to read. They are blank and maybe a few minutes to hours later they will open up and be able to be read. 2. when sending it says couldn't send because timed out then next try it sends but does not show up in the sent file. Also, things do not show up in the delete file. It is very slow to open and log in to whatever the process it goes through as it say "logging in......." This started on Saturday 8/22/26. Please help. I am not a computer geek. I really don't know what is going on. Thank you for your help, Donald

Hi Folks,

Mozilla VPN no longer works on my Windows 10 PC. The program runs and the little desktop window appears. However, when I click Mozilla VPN on, it clicks off immediately. Ideas?

Android Severe page loading issues on Google, X, Facebook, and Cloudflare verification sites (Last 3 days)

Dear Firefox Engineering and Support Team,I am writing to report a critical browsing issue that started occurring about 3 days ago. This issue severely impacts page loading on major platforms and makes browsing nearly impossible.

1. My Device Environment:OS: Android 12Affected Versions: Firefox Beta (Primary), Firefox Nightly, and Firefox Stable (All are updated to the latest versions).

2. Detailed Description of the Issues:Google.com: When searching for keywords, the browser frequently encounters a "Page failed to load" / "Unable to connect" error. If the search page manages to load, switching to the "Images" tab instantly triggers the page load error again.

Social Media: The exact same page loading failure happens frequently when trying to access x.com (Twitter) and facebook.com.

Cloudflare Captcha Verification: On websites requiring Cloudflare verification via Google search clicks, the browser immediately crashes or kicks me out of the page right after clicking. I have to attempt accessing the link repeatedly (several times) to finally get through.

Desktop Mode Trigger: On all tested Firefox versions, forcing the view from "Mobile mode" to "Desktop mode" immediately and consistently triggers the page loading error. 3. Troubleshooting Steps I Have Already Taken (with NO success):

Cleared all browser cookies and cache.

Completely uninstalled and re-installed all Firefox versions (Stable, Beta, Nightly).

Removed all extensions and tested on a completely fresh, vanilla installation with zero add-ons installed, but the bugs still persist.

Since this issue happens across all Firefox release channels (Stable/Beta/Nightly) even on fresh installations, I suspect it might be related to network stack rendering, user-agent handling, or an incompatibility introduced in a very recent upstream update affecting Android 12.

I would highly appreciate your investigation and guidance on how to resolve this.

Thank you for your time and continuous dedication to improving Firefox.

Best regards, M_Ng
