Firefox Community Forum

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?

Hi

Lets say i have 100 tabs open in my session. I mistakenly open a new window with one tab. After closing this window and starting firefox again, it starts with this one tab, so i have lost all my previously opened tabs. Is there a way to get those back?

Thank you very much. Dimitris

I have read all your tutorials. I was unable to have an important televisit with my doctor yesterday because nothing I tried worked. I am unable to use webcam for other sites until I resolve this problem. Previously I had no problem with my webcam but recently had to get new pc with windows 11 & needs to configure my pc to address this issue. I have another appt scheduled with another doctor & need to fix this problem asap Thanks

Every time I access the web I get a report from Norton saying "Threat secured". It attaches every single website that I open. See attachment for some exmaples (only variabole part of message shown apart from first one).This is occuring 50+ times a day but does not occur using Edge, so it appears to be related to Firefox. PLEASE help. Norton have not helped with this. Thank you- Colin O'Brien

I was creating a primary password and for some reason it "glitched" or "stuttered" and it created the password without me knowing what it was. I tried several combinations that could be close to the one I was inputting. Can I uninsall Firefox and reset the password?

I cleaned the AppData folder to speed up the computer, then it turned out that there were Mozilla files, which threw away all my data form browser. I synced the browser data on the phone, but it didn't transfer everything (history and login data missing). What to do to have my passwords again on the computer?

Every time I make Firefox full-screen, it immediately crashes and shuts down. I have restarted the computer, uninstalled and reinstalled Firefox, but it still doesn't work.

When using the new version of Firefox, I found that bookmarks only appeared in new tabs. Once I opened other web pages, there were no bookmarks above the screen, which made me feel inconvenient. Previously, the new tabs could also be customized, but now they can only be blank or the default pages of Firefox. So, can the new version of Firefox solve these problems? Or which of the older versions of Firefox can still meet my requirements?

Hello. I frequently shop at particular store and have never had a problem.

Now, it's off and on. One order will go through with the help of their customer service (doing a direct purchase). Then a few weeks later I don't have a problem and can order without assistance. Now, once again, I can't purchase anything. Once my credit card goes through my address disappears. Then I add my address again and then my credit card is deleted. When my address or my credit card is deleted the order has in bold red letters telling me to add it again. I've tried Chrome after Firefox had issues but it had an issue too.

Is there something I can disable while I shop? I'm not having any problems with any other sites. Thank you!

No matter what settings I change, I still can't get audio to play from Firefox. I can use other browsers and get audio so I know it’s not my computer. I’ve even tried to uninstall firefox and install the newest version with no luck on getting my audio issue resolved. If anyone has any advice for me, it’d be greatly appreciated

Hi I need help as my Firefox browser got uninstalled this morning I had to reinstall and all my saved data has disappeared,

Please help retrieve old mozilla firefox data.

I like Firefox - it's been my default browser for a long time. But I am getting REALLY tired of websites not working with Firefox but working with Chrome (which I hate) and now DuckDuckGo. Specifically, federal government websites like Social Security, Id.Me, and I.R.S DONT WORK WITH FIREFOX!!! Also California DMV. Now I'm even having problems with commercial sites like Outdoorsy.com! I shouldn't have to switch but I'm getting real close to just abandoning Firefox. I will also add that the number of times I have to download a new version, then delete my session, let it load, and then use history to restore previous session is also VERY ANNOYING!!!

Bug Report for Mozilla Team: When you open a Gmail PDF In another window, the zoom setting has a bad response, with much delay, I inform you of this Bug So you can fix it, thank you very much.

I recently re-installed FireFox after I suddenly had problems that the profile folder could not be accessed. I uninstalled it, then reinstalled it using the download from Mozilla website. This fixed the profile issue. I am using the latest version. Now, I find that most of the time, cnn.com won't load: I see messages on the bottom left corner that it is connecting to all sorts of web sites, in particular it tends to get stuck on "Sending request to signal-metrics-collector-beta.s-onetag.com" . I don't know if it eventually loads, I give up after about 1 minute. In Chrome, cnn.com loads instantly. In Firefox, BBC.com loads instantly. Microsoft.com loads instantly. I have installed the same extensions as before. I started FireFox with all of them turned off, no difference. As I mentioned, it does not load MOST of the time - once in a while it loads instantly, but later on the problem reoccurs. >What is wrong with FireFox and why won't it load CNN as quickly as before? I am using Firefox on Windows 11, I have Malwarebyes installed. Thanks, Adriaan
