I'm having trouble opening urls in a private window from the command line on Windows 11.

Firefox version: 144.0.2

Starting a new private window works fine with "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window

But doing: "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window "https://www.google.com"

just opens the link in the last selected window if the last window selected is non private it just opens the link there instead of a new or existing private window

I have also tried with no success: "C:\Program Files\Mozilla Firefox\firefox.exe" -private "https://www.google.com"

I use McAfee as my security system. They recommend going to Firefox settings and disallowing random site connections. How do I get my system running again.

Firefox 144 Installed Today; Clobbered all of my Tabs. "History" is No Help

Something very bad happened to me today (11/3)....

Firefox 144.0.2 was installed on 10/30/25, and everything has been fine until today. I don't know why or how, but ALL of my OPEN tabs (of which I have many--and have it fixed so they always re-open when Firefox starts), ALL went away.

In reading conventional steps to recover such from sessionstore-backups, those instructions sounded straightforward. However, even though ALL FIREFOX PROCESSES were ended, I could not copy the contents of the sessionstore-backups folder nor could I delete anything--EVEN THOUGH I am the owner.

Even after providing Admin perms.

I could get rid of profiles.ini, which initially proved diasterous, because then Firefox thought I was brand new, so ALL of my passwords saved through Firefox these many years, went "poof".

Fortunately, I was able to get that back, but I still cannot get all of my tabs back, and conventional instructions to do so aren't working.

After recovering from my heart attack for initially losing my passwords, I am breathing a little better right now, but it sure would be nice to get all of my open tabs back again. I don't know why I am not able to manipulate the files within sessionstore-backups. I think if I could eliminate the files in that folder EXCEPT for upgrade.jsonlz4-20251027123126, which possesses a 10/29/25 date, these should be the open tabs just before the 144.0.2 installation, and all should be right with the world, once more.

I have performed/examined many steps offered under this category, but most assume I can copy them elsewhere for safe-keeping and/or removing all but the one I want Firefox to "use". Because something is preventing me from doing this, though, I am being stymied in what ought to be the solution. As a test, I was able to copy files from a much older profile--so I can prove the basic steps SHOULD HAVE worked. Unfortunately, I cannot do the same with THE (more recent) folder in question. I can't get rid of parent.lock, either (and I have ensured no Firefox processes are running via Task Manager).

Repeatedly.

Something else is at work, here. Any help or assistance from community experts would be most helpful.

Thanks very much in advance.

image of problem Some, but not all, pages browsed throw up a "hamburger" menu, top left of the window. (the link above should link you to a screenshot taken this morning in Firefox 142.0.1 (64) running on Win11.)

The menu button floats eternally over the text in that top-left corner. This irritates me because I read text, and am frustrated by the browser covering readable text.

I can't remember ever (20+ years) needing the Table Of Contents of a web page. I use Mozilla Firefox's excellent Edit, Find if I want to jump directly to a key word.

Anyone who can suggest a perpetual dismissal of this menu button will earn my lifelong admiration!

I can deal with Settings, About:Config, and even RegEdit. Thanks, Chris

Hello.

After the recent update that added profiles to Firefox I have gotten them working on my personal computer but not on my work pc.

The option for creating profiles showed up once when launching the browser but I had to dismiss it at the time. Now I can't find the option to create profiles any more, I have followed the guides that mozilla have put out but the option physically is not there.

I have also tried reinstalling Firefox but that also did not work.

what do?

Thanks.

Just built a new PC and using Win11. I like to have a pinned tab in Firefox playing some kind of media to have background noise. Since new build, whenever I am not 'focused' on that tab and doing other tasks, audio from that tab will cut/fade in and out.

I've been working on this for 16 hours. I've googled, binged, even yahooed. No answers. Checked and rechecked all settings, both system and browser. Uninstalled/Reinstalled *many* applications, including Firefox. My OCD won't let me rest till I have this solved.

Thanks for the help.

Recently, when I open a new tab in Firefox (Windows) I started getting a drop-down box for Google instead of shield, lock, and sliders followed by the query/address bar. See attachment. I have no way to drag and drop this search query address. If I follow this by clicking on the search icon in the Google query field below, I get the normal Firefox address bar with the lock icon and the ability to save the query address by dragging and dropping the lock icon. How can I get back to the normal Firefox browsing address bar.

Hi,

I'm having an annoying glitch since the recent Firefox update. Now, when I am looking at a webpage the tabs at the top of the screen disappear and the webpage automatically maximizes and, to see your tabs you have to hover at the top of the screen to see them again. I do NOT want that! I want to see my tabs at all times! How do I change the settings so that I can do that? I sincerely hope that this "improvement" can be deactivated!

Since a month or so, Firefox browser freezes when playing youtube videos. Simply closing the app and restarting won't do the trick, I am forced to open the WIN Task Manager and manually "end task" before I can watch youtube videos again ... until an hour later, or lucky a day later, the same drama unfolds. I run the newest version of each, Firefox and Windows 11. No new extensions or plugins have been added recently. What is to do here? I'm since Netscape on this route and would hate to switch to another browser... :-) Thanks in advance!
