Hi everyone! 👋

How can I troubleshoot common issues in Mozilla Firefox, such as slow browsing, pages not loading, or extensions causing problems? What are the best steps to improve browser performance?

Any tips or solutions would be greatly appreciated. Thanks! 😊

Each time I power up my laptop I want my page to go straight to my Yahoo Mail. It does do that but it also tries to open another page that errors out. I think its because there's a 'c in the address and the file can't be found. I don't know how that filename got written into the Start Up Program and I can't find it to remove it. Please tell me like a First Grader how to remove this error message.

http://"c/Program%20Files/Mozilla%20Firefox/firefox.exe%22%20-new-window%20https://mail.yahoo.com/

It says it cannot open the page.

Thank you for any help you can offer.

Microsoft seems to have interfered with my computer. I have been using it for 10 years using Mozilla Firefox with no problems. Now all my own documents have been frozen and I am unable to make any alterations or continuation of text. I am desperately worried. I am 83 years old and started using computers relatively late in life. I am a complete 'generational novice'. It seems as if Microsoft has had some input. Please help

Your current build of firefox runs substantially worse for me than previous versions. I use Firefox because it is non-chromium, which typically offers more user freedom and control, but these new performance settings which cannot be edited individually, but are controlled automatically, are overstepping. Please advise how I can change the settings on a deeper level than simply switching off hardware acceleration. I'd like to limit multiprocessing primarily, but I would also like to have access to other performance settings. Further, I would like to have more control over how Firefox can access my devices. Please advise how I can access and edit the full list of permissions available to Firefox. I ask for this in the interest of transparency and personal data protection.

what have you done with the? "new" firefox since the last update and change, it crashes, it won't open websites and now it said prove you're not a robot and other miscellaneous things are going on? Can I go back one update? I dislike what you have done. Firefox has always been my first choice and not Chrome, I'm going to have to find another search engine.

New user of the Mozilla VPN for MacOS 26 (soon to be 27). I have two questions: 1) how can I exclude a website from the VPN? The Roku website, accessed via Safari, does not work with the VPN installed and enabled. The only instructions that I have been able to find use a Firefox extension that only works on Windows. 2) When I turn off the VPN, or quit it, I lose internet access. I have to uninstall the VPN client (I use AppCleaner) to effectively disable it and maintain internet access. How can I temporarily disable or quite the VPN and maintain internet access? Thanks !!

Mozilla VPN does not start service on start up as before, nor allow me to start the service on my Dell laptop running Windows 11.

I appear to be signed in and while I can navigate to different areas on the desktop app, it does not allow me to 'turn on' the VPN.

I am new to Mozilla vpn. Running Linux Mint on HP laptop using firefox 155.0.1. I lose internet connection the second I turn on Mozilla vpn. I get error message "no signal - check connection". This is regardless of the chosen location. What am i doing wrong?

I been using FireFox for at least a decade I am really disappointed in it's current state. It is very slow OIS is Version 26.6.2 (25G83). Constantly telling me it can't find server when I hit an website link? Also frequently says secure connection? I want my FireFox back.

I use Firefox to watch several of my live news programs on their web sites. Recently I am finding that the volume control does not allow access to actual control (it is on or off choices) without going to full screen. And tried a couple on edge. In fact, the first below will NOT LOAD in Firefox. https://www.mysuncoast.com/livestream/ https://www.fox13news.com/live So far skynews.com/watch-live has still let me balance the sound levels. What is going on? Is this a choice of the providers to not allow control? A recent change in YOUR end? I really hate to have to drop Firefox and go to Edge for my live news broadcasts, but this is what you are forcing on me..... Scott Hepburn [email removed]@verizon.net

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 ...

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 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?
