Firefox Community Forum

My Home page is a local HTML file featuring a CSS-based tabbed notebook holding links organized into various categories. When exiting FF, I always have this page as the active browser tab, so that on start-up it's still the active one in the event of multiple open browser tabs.

Until v151.0.4 (and still now with v152.0), if I exited FF with the active notebook tab (actually a styled radio button under the hood) in my CSS tabbed notebook something other than the first/leftmost tab, FF would restart with that being the active tab, but after a few seconds of CPU activity as the browser initialized the active notebook tab would switch to the first/leftmost one. (In my HTML I also have <input type="radio" name="tabs" checked> specified for this first/leftmost instance.)

Since the update, however, it remains stuck on the one from the last browser session as first displayed. I suppose I can live with this, but I do wonder what accounts for the change in behavior. If it's by design, where is it documented? If not ... maybe it calls for a bug report.

I get an "access denied" message when I do a search within a web site that I am connected to. Problem is with Fire Fox. Do not have the problem with google chrome.

Just checking Facebook "download your information" and got this:

```

     {
       "timestamp": 1781017200,
       "label_values": [
         {
           "label": "Date",
           "value": "2026-06-09"
         },
         {
           "label": "Business or organization",
           "value": "Firefox",
           "description": "The business or organization that added you to a Custom Audience"
         }
       ]
     },

```

Is this actual Firefox passing my info to Meta, or some Meta scammer pretending to be Firefox?

On that date, I had Global Privacy Control turned on in Firefox.

I have recently discovered that Firefox is constantly sending data at around 3KBytes/S to a variety of Cloudflare servers.

What is the data that is being sent and why is this happening?

This has started to occur in one of the last updates to Firefox.

Currently running 151.0.4 (64-bit) on Windows

Does this constitute a privacy violation, what is the data that is being sent?

Hi there!

Firefox did an update today and the firefox VPN option disappeared, there is no option in settings or the menu for the VPN any longer.

Thank you!

Firefox promised us an gen ai kill switch. But theres this new ai summary feature that is not automatically disabled when i press the kill switch. Could you fix this, so that when i press the disable ai button all gen ai features are disabled! Even the ai summaries feature. Could you also not hide or try to sneak in any more ai features! Nobody needs ai features, it's actively making us all dumber. Thank you.

Please create a new version of the browser app that supports the ability to use FileSystemAPI on directories, this is essential for working with a BeatBuddy project and SD cards that are saved on my computer using the online editor. Many thx, Manfred

I decided to switch back to "mainline". Opened Firefox after a while. Got a prompt to change my new tab wallpaper, I said no.

Closed and reopened Firefox. Then my new tab page was besmirched with "soccer" score nonsense.

What hidden/non-obvious setting do I need to change to have ALL of this and ANYTHING EVEN REMOTELY LIKE IT off FOREVER? I will never EVER want ANY suggestions for ANYTHING for the rest of time. I turned everything I could think of, including the labs or whatever off but this still came up.

when accessing websites where Cloudfare is part of the sequence the page hangs on cloudfare and the page is not displayed. Every time data is transferred through cloudfare the page hangs on cloudfare rending the search useless.

Since the last update on both my desktop and laptop web performance has slowed considerably. Some sites time out, some just don't connect. I've tried VPN on and off, changed security levels, deleted extensions to no avail. I use Windows 10. Is this the future with FF? Time, after many years using FF synced across all my devices, to bail?

Please advise soonest as this is more than frustrating and unproductive. Thanks Stephen

Hi,

I am using macbook pro latest one, and when I use firefox and scroll down from my wireless Mouse to the bottom of the page, the scroll bar jumps to the top while working, is there a fix for this.

Thanks
