Disable "Open Firefox every time you restart your computer" opt-in prompt

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

How to debug FF startup, not using the profiler? After reboot, FF always takes 14 minutes to start the first time.

I run the latest Firefox (v122.0.1) on Windows 11.

Since last week, FF takes 14 minutes to start the first time after a boot. :-( Usually FF starts in ~3 seconds.

I reboot the laptop. I wait a minute. I start FF. Nothing happens for 14 minutes. Finally the browser window suddenly appear and everything is working normally. I exit FF (no remaining firefox.exe processes are running). I start FF again. Now it starts immediately as usual. :-) But: I reboot and start FF. Again, it takes 14 minutes to start. This is reproduceable every time.

I haven't tried to *solve* this by refreshing FF or simillar. Right now I'm more interested in debugging this and finding out what is wrong.

I found https://profiler.firefox.com/docs/#/./guide-startup-shutdown which states how to automatically start the profiler at startup.

12:40 I boot the computer, login and wait a minute. 12:43 I start CMD.EXE and run:

 cd c:\Program Files\Mozilla Firefox
 set MOZ_PROFILER_STARTUP=1
 set MOZ_PROFILER_STARTUP_ENTRIES=20000000
 set MOZ_PROFILER_STARTUP_INTERVAL=100

12:44 I run:

 firefox.exe

No GUI appear. (it won't appear until 14 minutes later) I open the Task Manager and see one (1) firefox.exe process, taking 0% cpu. (pid 17668) 12:48 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:50 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:52 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:54 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:56 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:58 The browser GUI finally appear. Everything is now normal. It is showing one (1) tab with my start-page (google) just as it should. (my Task Manager now show 12 FF processes running, with various options) 12:59 I click the icon to stop the profiling.

I open the profile. [Profile Info] says:

 Recording started: Sat 17 Feb 2024 12:58
 Recording length: 1m12s 

So my profiling data don't show what happens between 12:44 to 12:58 :-(

Just for the sake of it, I'm attaching a pic of the first 10 seconds of the profile (at 12:58).

PS: Between 12:44 and 12:58 no FF window exists at all. Alt+Tab show no FF and in Task Manager I can't do any "Window" management, it is greyed out. I.e. no FF window exists for this process.

Question 1) What should I do to debug what happens between 12:44 and 12:58?

Question 2) How can it be that it takes 14 minutes to start FF from scratch (boot) while it starts quickly (~3 seconds) if it has been started once? I mean, all firefox.exe processes are gone when I exit FF, so starting FF again should be like starting from scratch, but apparently something is different.

Question 3) Is it normal that a FF, with only one tab (https://google.com/), run 12 processes in Task Manager?

Are there backup folders I presume or reading of a Json folder where session profiles are kept, if so how can I insert this folder for the primary session to restore lost session?

Running Windows 10 and Firefox 102.9.0esr 64-bit. I seem to have affected the print facility so that the contents of a frame within a webpage do not print. The frame contents do show on the preview screen but then disappear when the Print button is pressed and they are not printed. The rest of the webpage is printed OK. Typically this happens to the 'Sellers Description' on an Ebay item. I have upgraded to Firefox 115.7.0esr but this has not fixed the problem. The print works fine on another machine running Windows 10 and Firefox 91.6.0esr 64-bit. Is there a way to get the full print back? Regards, LRB

Today a website told me I needed to enable JavaScript in order to continue, despite the fact that it is enabled. At first, when I received this message, I turned off the "NoScript" extension and tried again, but the website still gave me that same message. So then I went to the about:config page. and it showed that JavaScript is enabled because it showed a value of "true". This sort of thing has happened more than once in the past. I'm forced to go to another browser such Microsoft Edge or Chrome, where I do not encounter this problem. Why is this happening in Firefox, and what can I do about it? My operating system is Windows 10 Professional, and if you need any other details, please let me know. I will appreciate your assistance.

This is so very simple and so the fact that it seems impossible to get a straight answer makes me instantly suspicious. Here is the question: What is my location? Simple! In other words, I have Mozilla Firefox installed on a physical device, which HAPPENS to be a desktop computer, not a mobile phone, etc. In other words, it stays here. So why do alllllll the sites act as though I am literally 930 miles...from my actual, physical location! I have NO VPN running...none. Unfortunately, Firefox is using Google location services, WHICH IS THE PROBLEM. I just installed Firefox, instead of Chrome, to solve that problem. I guess THAT was a stupid move, Firefox is worse!

There needs to be a manner in which the USER can INPUT THEIR LOCATION. I'm not trying to "trick" anyone...I'm actually trying to give people ACCURATE INFORMATION which apparently is beyond the capabilities of the internet, to provide.

I had posted my question yesterday and received a response from jscher2000. I sent a reply to the response by email a short while ago, but I wasn't sure it went through. Therefore, at the possible expense of having you receive the reply twice, I have recopied it here:

Thank you for trying to help me download Firefox onto my computer. As per your advice, I first tried shutting down and restarting my computer. That did not work. Then I went onto the link you sent me: https://www. mozilla,org/en-US/firefox/all/#product-desktop-release . The installation began, but only got up to around 80 - 90%. It stopped at the point where it said Execute: "C:|Program Files\Mozilla Firefox\default-browser-agent.exe" register-task 308046B... (It looks like there might be some more letters and/or numbers after the "B", but I can't see what they are.) I waited a few more hours to see if the installation would continue, but it did not. I then went back to try downloading Firefox in the regular way. First I got a message, "Now installing. Firefox will be ready in just a few moments." Again, installation proceeded to around 80 - 90 %, and then I got a message, "Hmmm. For some reason, we could not install Firefox. Choose OK to start over." Starting over didn't help. I got the same message. Any further help or advice that you can give me would be greatly appreciated. drzee1946 email: [removed from public support forum]

I've discovered it has something to do with Amazon.

I didn't know I had it until I just migrated to Windows 10 and a new firefox update occurred.

Even then, my only clue is a little orange "triangle" that shows up at the top line of the 'hamburger' menu at the top right on the screen. When I clicked on it, I got a message saying "Silk Privacy Pass wants to update".

I went to my installed extensions/themes screen and there is nothing about a silk extension or add-on.

It also showed up when I looked in the startup configuration and it showed it was loading during startup there. I disabled it. But today I just got the orange triangle again an hour ago wanting me to let it update.

I want it gone!! Especially when it showed up on my system without my asking or knowingly agreeing to it.


FWIW, I also ran Agent Ransack (search utility) on the drives and "Silk" does not come up as a file name for an app, DLL or any other file.

Last time I tried backing up my bookmarks, they were saved in a file that was basically a list, a list that can't be imported back to Firefox bookmarks, but just a list. I would like to know if there's a way to actually export and import bookmarks with one click, rather than me having to add 200 pages from the list manually. When I tried importing the file, the list ended up somewhere random and not where bookmarks are

Hello,

I work for Microsoft, and one of our sites offers users a way to opt out of personalized advertising on some Microsoft domains by setting a cookie. The site: https://account.microsoft.com/privacy/ad-settings/signedout

When the user clicks the toggle to Off, we cycle through four domains via an iframe and write a TOptOut cookie on each one. If everything is working properly, the user should then be able to go to www.bing.com and see a TOptOut cookie on Bing that will prevent personalized advertising on that domain.

The problem is, this stopped working in Firefox. We have verified that it still works* in 115.7.0, but in 122.0.1 and 123.0, the cookie is written and then deleted on refresh. If the user doesn't already have Bing open in another tab, they'll never see the cookie at all. I have verified this behavior in Bing several times, on my work machine (Firefox 122.0.1 on Windows 10) and my personal machine (Firefox 122.0 snap on Xubuntu 23.10).

  • It still works on our corporate VPN in 115.7.0, but not on my coworker's non-VPN machine. Same version. I'm really not sure what's up with that one.

This is a large concern for us. Because the cookies can still be written, it doesn't trip our test for third-party cookies being disabled. Because the cookie for microsoft.com is written, the toggle will show up as Off even after a refresh. This is misleading to our users.

I have gone over the Firefox docs on Enhanced Tracking Protection and Total Cookie Protection, but neither seem to handle this case. Firefox does not block any trackers on account.microsoft.com or on www.bing.com. It's fine if the cookies are in separate jars, we just want them to be written to the proper domains and not deleted. Can anyone tell me what changed in Firefox recently? Is this expected behavior, or a bug? If it's expected behavior, what can we do to allow users to opt out of personalized advertising?

Just what they title says. If I launch Firefox and immediately click in the URL bar to type in a search, instead of preventing the page URL from appearing, it adds it after my cursor once the page has loaded. For example, if I launch Firefox and immediately start typing "weather in my area" it becomes "weather in my areahttps://www.youtube.com/feed/subscriptions".

This is a mild frustration, but a persistent one. It must be possible to fix, because other browsers (Chrome) are clever enough to not add any text once the user clicks the URL bar. What can I do to stop this from happening?

Since last upgrade Firefox seems unable to access any wordpress sites.

Always says to enable cookies. I've done that but still not possible access.

Is Firefox now becoming so "secure" it is useless?

There are more and more web sites where Firefox just is no longer a viable browser.

There is no clear "ENABLE" cookies option to resolve this just pages on explanations about safety yada yada yada.

I just want a button that says ENABLE COOKIES so I don't have to constantly seek answers to use this browser on a particular web site.

As much as I hate Chrome I am finding it more useful now than FireFox
