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.

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?

Thunderbird hangs immediately as soon as I click the Junk folder. Another issue that may be related to this. I posted a question about Thunderbird hanging in a few minutes after starting. It hung this morning when I was downloading the message. The inbox, which had hundreds of messages, became empty. After I downloaded messages again, it had over 6000 messages, most of which were junk. It seems the junk filter is not working now. Could anyone offer a tip on the remedy for this?

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.

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.

2~3日前にも同じ状態にになったのですが、ヘルプをいろいろ調べているうちに正常に表示されるようになりました、ヘルプを調べているうちにトラブルシューティングを押していたのかもしれません。…が、今日ももんだいなくしようしていましたが、一旦停止してい、次に作業を再開すると　 またメールフォルダーが消えてしまってました。今回はトラブルシューティングもしてみましたが、全くどうにもならないのですが、 何とかメールフォルダーを表示するほうほうがないでしょうか？…私は視力が非常に悪く視界もごくわずかしかないので、PCの画面も読むのに時間がかかり。返事にも思うように打ちづらくいろいろと教えていただくのに手間をおかけしますが何卒宜しくお願い致します。

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.

ThunderBird for Linux crashes down automatically every 5 minutes since the last update. Every time I log into my account, about 5 minutes later, I see from the monitoring terminal that ThunderBird's temporary memory usage suddenly soars to over 90%, and then the entire program becomes unresponsive and must be closed and logged in again. But after that, this situation keeps repeating, and it is impossible to use it. Can anyone help? Thanks!

How do I get sound back on the add on extension "Check4change" ? it has always worked and then stopped one day. I have tried all the suggestions of reloading the extension and even removed and reinstalled Firefox, it was no help. I have sound in Firefox, just not while using the check4change add on extension.

How do I recover sound while using the extension?

Is there some way that I can nullify the format changes in the v128.x message list, compared to v115.x, so that my UserChrome.css tweaks that are functioning well in v115.x are not broken? Perhaps there are some new Config flags that might be set? I hate to have to redo a bunch of carefully calibrated work.

Sample of v115.15.0 message list included; I uninstalled v128, so I can't easily show a sample of that.

when I am on facebook I like to clear the history before I get off < but latley when I do this when I try to get back on it wants a password then a security code to make sure it is me Cant figure it out or get it to stop This is on Firefox* Bulleted list item

Google says they have a Cherokee/English Mozilla Firefox Translator add-on. I grew up on the Cherokee Nation 60 years ago and sometimes I forget a word. Where can I find this add-on for Firefox? The one answer I got from a volunteer was to visit the "Firefox store. I could not find the store either.

I tried to send an email and got a message saying "The message could not be sent because connections to Outgoing server (SMTP) pop3.gmail,com failed. The server may be unavailable or is refusing SMTP connections. Please verify your Outgoing server(SMTP) are correct and try again". I checked and they seem right but I cannot even send an email from one account to the other. The same message appears and I don't believe anything has been changed, aside from adding another address, that I know of.
