In one of my Firefox installs, the Profiler automatically starts recording every time I open Firefox. There's a button on the right that looks like a speedometer and it is blue until I tell it to stop. Then it is taskbar button color.

Profiler instructions at https://profiler.firefox.com/docs/#/./guide-removing-profiler say to simply drag this button off the toolbar and it will stop record. On restart, it's back on the toolbar, and it's recording.

I have tried refreshing Firefox. Doesn't help.

I have tried uninstalling and reinstalling Firefox, and then setting up a new profile. Doesn't help.

I have tried deleting prefs.js. Doesn't help.

I have tried opening up the developer console, opening settings, and unchecking "performance." Doesn't help.

I searched the registry and found a key called MOZ_ENABLE_PROFILER (iirc, something like that). I set it to zero. Doesn't help. I then deleted the key entirely. Doesn't help.

How do I get rid of this thing? It must be a registry setting of some kind, as it appears in whatever Windows account I open Firefox from, but I can't find it. It is deeply frustrating as the computer it is happening on is my oldest computer, and I don't want a recorder running in addition to Firefox.

On my linux system, I have two users. If I log in as user A and use FF and leave a bunch of tabs open, I can view those tabs again later if I restart my computer and log in as user A, so FF remembers its history.

No Problem Scenario Logged in as A - open FF - open a bunch of tabs - CLOSE FF log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are there

Problem Scenario Logged in as A - open FF - open a bunch of tabs - leave FF open (don't close FF before...) log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are GONE

If I run into the Problem Scenario, I can sometimes use these steps to get the history/tabs back. https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup

Whether the steps work or not, the Problem Scenario is annoying. I don't know what causes this. My desktop manager is KDE.

Hi,

the password manager (about:logins) is a very handy feature, i use all the time. However, tehre is so many pages where the FF password manager fails to suggest the correct login user name to fill in the "user" field. (Interestingly, the password fill is much more accurate).

To start with: for logging in on THIS VERY SITE for posting this question, I needed to:

1. manually open the FF logins page
2. enter the url "accounts.firefox.com" for search
3. pick the entry
4. copy the username
5. swithc back window
6. paste and confirm.
7. repeat for password (I think - or came this at least suggest correctly maybe)

What's going wrong? Is my installation broken - or is this for all users the same experience?

Tks

Hello, I recently purchased and started using the Hyperx Cloud 3 wired headphones. When I watch a YouTube video or shorts with these headphones, if I skip forward a few times or scroll to watch a new short, a loud popping noise occurs in the headphones. I turn the volume up and down, and it fixes it. Interestingly, this doesn't happen in other browsers, only in Firefox. This is very interesting, and I can't figure out why. I wanted to share this with you because I love Firefox.

NOTE: There's no problem with the headphones; they work perfectly. This is an issue only in Firefox.

On our web site (www.outlookmovie.com) we have the option to print documents and we also have a watermarking option

when we do a print and save pdf from firefox > file > print and save a pdf if the option watermarking is off , it works, if the option watermarking is on, it does not work (the pdf exported is zero octet)

could you help us resolving this issue ?

By the way it works when we use Chrome or Safari

Thx you very much for your help Marc Jenny mjenny@mjenny.fr

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

I always have two windows of Firefox open, one for each monitor. Up until recently Firefox would always restore both windows exactly as they were before I right clicked the Firefox icon in the taskbar and clicked "close all windows". This week however my browser will only restore one of the two windows I had open, and I have to restore the other one manually which is annoying. Can anyone help me bring back the old behavior so it restores both my windows every time?

Every time I boot Win 10 Pro, a half dozen Firefox pop-ups complain as indicated, as well as the wrong google page login (Voice instead of Calendar). There is no Firefox showing in the Windows>Task ManagerStartup> list. Firefox(143.0.4 (64b))> settings>General> Startup> has only [check for default]. I cannot find the controlling 'Startup' controls.

hi team, recently i can not open any PDF when i am in gmail using Firefox Browser is updated to latest verison, i have also check settings under application and whatever i choose, when click in PDF in my gmail, i can not open it directly, i need to go right click on it, open in new tab, then it downloads to my PC and open in new tab?. stupid isnt it? i have tried many settings and nothing seems to be working, any chance that i can just click on PDF and it opens in new tab or my Adobe app, without download it to my PC, cause sometimes i just want to see wtf is the attacment...

cheers,

The newly added PWA support is neat and was much needed. However there is an issue with the PWA icons under Windows, in the Start menu. In the all programs tab the icons are correctly the icons of their respective websites, but if the icon is pinned as a tile it switches to the default firefox icon making it hard to tell them apart at the first glance. The issue is present under Windows 10 and also Windows 11 How to recreate: Win10: -add a tab to the taskbar as a PWA -open Start menu -pin the PWA Win11: -install ExplorerPatcher and change the useless clunky win11 Start to the almighty and productive win10 Start -add a tab to the taskbar as a PWA -open Start menu -pin the PWA

Is there any way to fix the icons of pinned PWAs?

I'm having trouble installing Norton Password Manager, I keep getting a corrupt file, won't install, so I am running through the checklist of possible fixes.

The one I am up to is this :-

Refresh Firefox Click the menu button (≡). Select Help, then choose More troubleshooting information. Click the Refresh Firefox… button on the right side of the page. In the confirmation window that appears, click Refresh Firefox. Firefox will close and restart. When it finishes, a window will show the data that was imported. Click Finish. Choose whether to restore your previous windows and tabs, then click Let’s go!.

I cannot find the "Refresh"

I've run Troubleshoot Mode

I have cleared the startup cache, problem not fixed.

When I do "save as " action for an image in the browser it opens dialogue window to save selected image. Unfortunately it displays files and folders in some random order, rather than my preferred order (sorted alphabetically by name, followed by sorting by type).

I can see no rhyme or reason to the way Firefox lists files and folders in the dialogue window, so every time I am saving an image I have to sort things by name and type before I can find what I want.

This is not permanent so I have to repeat this action every time I save an image.

How do I, please set application preferences? to make this setting permanent?
