Firefox Community Forum

All my other browsers work fine but since April 4, 2025 Firefox won’t work at all. Websites won’t load. I have tried to clear my cache & cookies, I have checked my connection settings, I have checked for malware, I have turned off all my extensions and I have completely restarted my computer several times now, nothing has worked. I also did trouble shoot mode & reinstalled Firefox (though I will admit I maybe didn’t do this step properly). I refreshed Firefox. Why is it not working? What happened? I don’t know what to do as I don’t want to lose all my bookmarks and passwords that I have yet to move over to my password manager. Please help.

starting just now, firefox will not take me to ANY website. All other browsing services are working. I have tried uninstalling and reinstalling and clearing cache and cookies.

If I cant get this fixed for my job I will go back to chrome and never download or retry this again. I will also never recommend firefox to anyone like I have in the past.

(Title): VPN is not working on my laptop

(Description):

Hello, I installed a VPN on my laptop, but it is not working. I cannot connect to any servers. I have tried restarting my laptop and reinstalling the VPN, but the problem still exists. How can I fix this issue?

Thank you.

Why does this happen? I was even logged in, and my tab groups are gone. Why??? Do I need to use a different browser? And Firefox has had trouble with some websites where the paying portion is not correct. However, if I go to a different browser (Chrome), the paying portion works correctly. I'm getting kinda tired of these weird things going on. Please don't offer a feature that doesn't work like grouping tabs.

Today: Can't access website. I think it is the ISP or the router. Reset the router. No luck. Tried a different device on the Wifi. Works fine. Tried a different browser. works fine. Shut down Firefox. I had 2 browser instances open with several windows in each. Could not restart firefox, as it did not close correctly. I closed the broken instance(s). opened FF again, only got one set of windows, not both sets. The other instance had a bunch of grouped windows, and the groups seem to be gone. I can recreate most of those, but had some windows with ongoing work and things I wanted to look at and now they are gone.

FF crashed when I tried to get some answer from ediblearrangements.com help.

Hello!

I have Firefox in all my units and it has worked very well over the years. Until I activated Avast SecureLine VPN on my computer HP Microsoft 11.

When the computer is connected to wifi/internet and VPN is activated, the Firefoxprogram won´t start correct. It says I am offline. If I then turn VPN of and update the page it will work immediately. As soon the page start the update I can turn VPN on and it will work on every link and page.

What can I do to get rid of this problem?

/Mattias Forsberg

Have an app with a web interface that I used for years, but not with several of the latest versions of FF. Chrome, Edge, and DuckDuckGo all show the page as expected and the page functions properly.

URL: http://127.0.0.1:8384/ Error looks like this:

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:[port number].

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Have tried a large number of things including:

Ping works for ip and hostname, v4 and v6 Confirmed address is accessible through other browsers Disabled extensions Added exceptions in Settings for HTTPS-only mode Various settings in about:config, careful to return them to previous states when they didn't fix the problem Tried Safe Mode (aka Troubleshoot Mode) Refreshed Firefox (as prompted before uninstalling)

My last step is to reinstall, but thought I'd ask here first. Has anyone seen this before?

Along with many other Firefox users, I have a long-term problem with a PR_END_OF_FILE_ERROR in Firefox. How can Mozilla Support fix this problem for me? Can you send a link with the solution, or something?

Thank you, Joseph Seecchack, [edited] @aol,com. I eagerly await your response.

I'm on an older Macbook Pro with OS 10.12.6 My browser says it's up to date.

It seems that ever since I did a sync-up with another Macbook, glitches have appeared on this machine. One thing happening now is that some websites take forever to load in, and others won't load at all. With other sites there's no problem. I have a fiber optic connection. The speed test indicates that all is good. I did reboot recently.

I'm wondering if some sites are using advanced scripts that my older machine doesn't like, or perhaps recent updates from Firefox just don't work as well on this machine. Any suggestions??

I would like to open attached docs and print them. They are appearing all black with some verbiage, or multiple pages are all white. What is going on? How can I fix this? Step by step instructions, please. Technically challenged. I do NOT use cloud. will not be using it due to privacy and hacking issues. I save everything to my harddrive.

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

Adding the images below.

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

Hi for some time now i have been having issues connecting to my website.. it loads every other site but when i try and load mine on firefox it comes up with no internet connection but my site works on other browsers.. anyone have any ideas on a fix for this ?

My Firefox is using a lot of data; I don’t know why.

I am not using Firefox, and it is not running in the background, yet it is always using the internet. So what do I need to do in this situation? I tried to stop the internet connection using outbound rules, but it did not work. It is still using the internet. What is the reason my browser has high data usage? I have high data usage; in fact, in the past 12 days, we've used 30+ GB of data.

I get the server not found error on almost anything.

Hmm. We’re having trouble finding that site. We can’t connect to the server at [literally almost any site] If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

The site usually loads after I wait like 2-3 mins before reloading the site, or I force reload it around 7 times, but I cannot find a way to make the issue go away. I have refreshed Firefox, I have uninstalled and reinstalled it fresh, I have opened Firefox in Troubleshooting mode and the issue persists. I am at the end of my wits. Someone please give me something else to try.

Let's be clear: there IS zero support for FF. WINDOWS version notwithstanding, computer manufacturer put aside, my ability to properly plug-in the system to an AC outlet assumed, FF is DEAD.

I have been waiting for an answer, over a YEAR, and the issue at hand is the very basis for using a browser.

One day/once upon a time, OVER A YEAR AGO, FF throttled DOWN from 300mbps to - as of today, Sept 7 24 - 1-10mbps!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! It also started blocking access to websites such as my local Home Depot.

I switched to BRAVE.

I have "contacted"/posted this eventuation on every and all sites I could find with NO/ZERO response, broaching help.

Manu Andino (Mozilla Support), was the ONLY response I got and, of course, there is NO/NADA/ZERO help from him at the inappropriately, fraudulently, deceptively named SUPPORT.

This horror story is integral to the current trend of not caring about customers, clients, users and/or repeat "business". There exists NO technically competent personnel, with or without understandable accents, due to big, dirty, corporations or entities' attitude, that employee salaries/wages is money pissed-away. There is NO customer "service" outside of the way a prostitute "services" a service-person, on shore leave, in a strange port.

FF is dead. I have buried it. It is a painful memory whose name does not deserve to be mentioned.

This an interesting one. When running Firefox on my personal Macbook. I've been recently having issues loading sites like Reddit, Facebook and a few others in private browsing mode.

The issue seems to only affect certain sites, browsing the rest of the internet I have no issues. However, with these sites, they simply either will not load or require multiple refreshes to work.

Even more interesting, my work Macbook has a similar ecosystem and works fine.

I have updated and reinstalled Firefox, cleared caches and history. And run both with and without VPN. As well as being sure to reboot the Mac before trying each new attempted fix.

Does anyone have any idea what's happening or what my next steps might be before I go to Apple for help?
