Firefox Community Forum

When I click on Firefox and the to my email it says there is a problem with my internet. My internet is up and running fine. I have done everything it says Firefox can't connect to the server at mail.yahoo.com.

When I try to log into a site I have used dozens and dozens of times in the past, I get the following notice: WARNING: POTENTIAL SECURITY RISK AHEAD. This is a dead end from which I have not een able to proceed. The particular site I am attempting to access is the only site where I've encountered this warning. I called that site and was told that while they have been tweaking their security, since the warning message came from Firefox, I should contact Mozilla for help. So here I am.

I use desktop Firefox with newly installed Windows 11 (my profile erroneously sates w10). i must use the blocked website frequently, and so I need to restore access to it ASAP. It is a high security healthcare site, and as I said, they claim they could not identify a security problem, that the key to restoring my access is through my browser, Firefox.

Can you help me restore my access to the site? Thanks .... KH

I am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

Sample Messages:

Hi!

I am not sure how to address this. I like to have my pinned tabs always in view whenever possible. So when I click on another tab outside the tab, I'll utilize that and then go back home. While in other tabs, I may utilize the extension tab manager plus for Firefox. The last few days I'll click on a tab on need. It opens the page, but does not show the tab at the top of the screen. What is happening and how do I fix this?

Thanks.

Running Firefox 141.0.2 on Mac Sequoia 15.6.

I have frequently used firefox to reach this local server until today. The server itself currently responds to pings, traceroute works. I can ssh to the server. I can access an SMB share on the server. All of these were tested after I ran across this issue. The server doesn't support HTTPS.

Today when I attempted to reach the server in Firefox. This time I got a popup (from Firefox, I presume) asking if I wanted to add this server to some sort of list. As I am still largely human, I didn't really read the popup, and just selected "No". And now I can't reach the server (from Firefox, that is).

So, how do add this server to Firefox's whatever list? The "Server not found" message is, as always, not even slightly helpful.

Thanks in advance.

received an email that went to spam that my account will be deleted if I don't sign in or use Mozilla by Oct. I use Firefox every day. Is this legit? What do I need to do to keep mozilla

This is the message I receive when I try to sign in to my Adobe account online:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at auth.services.adobe.com.

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)

How do I check that Firefox has permission to access this page? Or, what else do I need to do to sign in to my account?

Thank you!

Any Ideas what is going on? About July 21st, 2025 I started noticing with a couple of browser tabs open, a new tab opens autonomously and flitters in the new tab name area, what "looks like a TagID", then closes by itself. I define "looks like a TagID" as something that looks like a tag at end of article link in popular newsletters I see, and appears in the url bar of the linked article.

The occurrence of the new tab happens when I open the browser, within 1 minute and occurs randomly during the session, perhaps every 20 minutes.

My first suspect/assumption is I am always signed into Mozilla when I open Firefox 141.0 (64 bit), processing an update now, Aug 5 2025. I have subscriptions to VPN and Monitor and I have sync (passwords and bookmarks) with my mobile instance of Android Samsung Galaxy phone.

My Desktop is set up as Windows 11 pro with one employer InTune acount for Microsoft but I limit that work to Edge browser.

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

Tabs are not restoring after session closed. I have tried the profile suggestion. I verified my settings say open tabs from last session. Rebooted. Cleared cache then opened tabs then closed and it keeps only opening one tab. It crashed last night with tabs on it and this was the results once I brought it back up.

The bookmarks and folders that I delete keep on returning. I have tried everything I know:

• disabled sync,
• deleted backups...
• deleted Firefox from my other devices

everything. But the deleted bookmarks and folders keep returning in my Bookmarks menu and in my Bookmarks Toolbar. Sometimes I get into "Manage Bookmarks" and I see the deleted folders reapper just a few seconds after I have deleted them. Any help would be greatly appreciated. I am at the point that that the next thing to try would be to switch to another browser

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.
