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?

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?

I love pocket but it is infuriating. I do something and a pocket page suddenly comes up with like 10 pictures and click links to articles. (And I don't know what I did to get this pocket page to come up. It happens when I do something online and I can't replicate it! It's always by accident. I google pocket and login but ti's not the same page with the same articles.) I see several articles I would like to read. I click on one and at least I can usually read that one, but then I go back and can't find the other articles I wanted to read and I cant get back to the same page displaying the articles. Now there are different articles! Today I clicked on one I wanted to read, was told to log in, which I did, then it took me to a pocket page which didn't have the article i wanted, and I cant find it. I also wanted to read another article and can't go back to find it either. This is infuriating! Can anyone help? And I doin't even know how to get back here to find your answer unless it goes to my email chaplaindon2000@gmail.com help!

Hi. Is there anyone having experienced similar phenomena?

1) Firefox stops showing Gmail correctly after a few days. Immediately after starting Firefox, I can log-in and open Gmail.com correctly. But after a few days keeping opening Gmail on Firefox, Gmail.com shows error messages regarding Cookie (please see the attached screenshot). If I do "Try clearing the startup cache" from trouble shooting information tab, Firefox shows Gmail correctly again, but after a few days the same issue happens again.

2) Fire fox cannot log-in on Outlook.live.com. As title says, I cannot log-in outlook live. Whenever I try to log-in from Outlook log-in page, Firefox shows log-in page again. This issue isn't resolved by inactivating "Enhanced tracking protection".

Both of them started to happen since the update around the end of 2023, I think. (On the other hand, Chrome works on both websites correctly)

If you have some information, it might help me. Thanks in advance.

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

I just installed FireFox but keep getting Chrome browser. How do I set FireFox as my default browser? My bookmark tab icons keep changing - how to change them back permanently ?

Again I had to create a new question because i still get an "Unexpected error" when I try to answer. (By the way I tried all suggestions to fix the error and also reinstalled Firefox but still have the error)

jscher2000 i think you are correct. The blue link in the PDF file is not a web link but a link to the specific attachment. It appears browsers are currently unable (not programmed) to access attachments directly. I tried in MS Edge with the same result. After contacting MS Support, MS stated that they are aware of the issue and that they are working to fix it in a future release of Edge.

Attachments can be accesses in Adobe Acrobat as you described, but it would be good to be able to access them directly from Firefox instead of having to save them and then using Acrobat.

When in fullscreen, if I move the mouse to the top-left corner and right click, a browser context menu appears. The page I'm on is using mouse right clicks, so this browser function is breaking the controls of the page if I ever accidentally click the top left corner (which I do often).

Is there any way to disable this menu appearing? I would never use this menu to minimise/close the program so I just want it gone. It's breaking fullscreen controls in it's current form

Dear Sir/Madam

I have set up a new Microsoft Surface pro 7 with fresh Win11 23h2 and office installation.

The latest Firefox 122.0.1 has been downloaded.

Problem:

When i sign in to my Microsoft 365 account for the first time everything goes smooth and get all authentication steps.

BUT

1. I never reach the Microsoft 365 page and return back to Microsoft log in page

"https://www.office.com/?trysignin=0"

2. if I insist in Trying I get in a loop and i get the error message "AADSTS50196 authentication error,"

3. I have tried to clean Cookies cash. The only difference now is that i do not get in that indefinite loop but i have to reenter the sign in credentials and again reach the log in screen.

4. I have entered the office.com, Microsoft.com, hotmail.com as trusted sites but problem same

5. No issues in that particular Surface pro to sign in Microsoft 365 site via edge

6. No issues to sign in Microsoft 365 in my other computers via Mozila. It happens to that particular surface new installation

Any help/Troubleshooting will be appreciated

Seit einiger Zeit wird bei Firefox eine Übersetzungssoftware verwendet, die leider (noch) völlig unbrauchbar ist. Möglicherweise KI-gestützt, aber noch nicht fertig. Folgendes Beispiel aus der Webseite von Bitdefender zeigt, was ich meine:

Richtig übersetzt bei Google:

• Glückwunsch! Sie schützen so viele Geräte, wie mit Ihrem Abonnement möglich.

Gleicher Text bei Firefox übersetzt ohne Sinn und Verstand:

• Glückwunsch! Sieten so viele Geräte, mit Ihrem mit Abonnement- und Abo-send- und Ab- und Ab- und Ab'

Die gleiche Art der Fehl"übersetzung" hat bei etwas komplizierteren Konfigurationsanweisungen natürlich unangenehme Folgen. Solche Fehler sollten doch eigentlich vor der Umstellung einer früher ja wesentlich besseren Software zu der neuen Variante bemerkt werden.

Mit viele Grüßen Jürgen Frikell

GOOGLE CHROME WORKING FINE BUT FIREFOX AINT WORKING

THANK YOU

I have the following settings in Settings/Preferences>General:

Files and Applications

Downloads Save all files in the following folder: Downloads Ticked Ask every time where to save a file

Applications Portable Document Format (PDF): Open in Firefox How should Firefox deal with other files? Ticked Ask whether to open or save files

On specific websites when I click on a pdf link, Firefox opens and automatically saves the file to Downloads folder without asking whether to save and where to save despite the above settings. As far as I remember, on other websites when clicking a pdf link Firefox only opens the corresponding file and doesn't save.

I found this with a internet search https://connect.mozilla.org/t5/discussions/stop-saving-pdfs-to-downloads-when-viewing-in-firefox/td-p/10225.

How can it be disabled that Firefox automatically saves PDFs?

Firefox tabs start crashing all of a sudden and won't stop crashing, until BSOD happens.

In my case it caused PFN List Corrupt Blue screen error.

How can I identify the real reason for the crash of the tabs, leading to the crash of the system?

I cannot log in to my Gmail account via www.google.pl in the Firefox browser. When I try to log in via www.google.pl, the Bad Request Error 400 message appears. The same problem occurs when I need to confirm login to other websites using a Google account. I simply can't log in anywhere. This problem does not occur in other search engines. A login icon appears on the www.google.com website, but not all related services from Google are available - Google account, Google Play, Gmail, Meet, Chat, Drive, Calendar, and Photos are unavailable - these are just the most important ones that don't work. Cookies are enabled. On December 25, 2023, this problem did not exist. I tried to restore Firefox to an earlier installation date, but it didn't help. I uninstalled the extensions and plug-ins. Unfortunately, the problem remains. Please help me. Regards, Bogaczewicz Bogusława.

When the system theme (light/dark) is switched globally, Firefox recognizes this and also switches its theme automatically (if configured appropriately). This should also retheme addons opened in the sidebar (Tab Stash or Sidebery for instance), and it does so under certain conditions, namely if either a) no sidebar was opened when starting Firefox and the addon sidebar window is opened directly, or b) the sidebar was opened with start of Firefox. Unfortunately, no retheming of the addon window occurs when some other Firefox sidebar (such as bookmarks or history) was opened after Firefox start and before system theme switch. In that case, the addon window (which is opened as the system theme is switched) does not retheme. This can be mitigated by either restarting Firefox or by opening a Firefox sidebar such as bookmarks or history, and switching back to the addon window.

So to reproduce this behaviour:

1. Open Firefox and some sidebar addon directly (such as Tab Stash in my case, with Ctrl-Alt-S)
2. Switch system theme globally (I do this with Night Theme Switcher in GNOME)
3. Observe that Firefox correctly redraws the addon window
4. Open bookmarks (Ctrl-B) or history (Ctrl-H)
5. Reopen the addon window
6. Switch system theme globally again
7. Observe that Firefox does not correctly redraw the addon window
8. Open bookmarks (Ctrl-B) or history (Ctrl-H) again
9. Reopen the addon window
10. Observe that Firefox redrew the addon window

This has already been reported to the addon developer, who stated that it might be a bug in Firefox, since his addon only tells Firefox which colors to use in which mode.

System details:

• OS Version: Linux 6.7.4-arch1-1
• Browser Version: Firefox 122.0.1
• Desktop environment: GNOME

How can I set tabs to automatically preload when I open the browser? I'm just trying to switch from Chrome to Firefox and I can't find such a setting here, although it is a very convenient functionality. I mean that when I open the browser, I can click on any of the tabs and it will be (partially or completely) immediately ready to work without additional loading.

I am using Firefox with the uBlock Origin and Cookie AutoDelete extensions enabled. When I try and load Gmail or any other Google site, I get a blank page and nothing loads at all. This only occurs when my VPN is on (I use Private Internet Access). However, even with the VPN on, Chrome will still load those sites. Disabling the VPN means that the sites load normally.

My guess is it might be some sort of privacy setting in Firefox, but I don't understand what it could be. The only thing that breaks/fixes the sites is connecting and disconnecting the VPN, irrespective of which country I try and connect from.

Hi,

What is the area above toolbox called (Firefox, File, Edit, View, History, Bookmarks, Tools, Window, Help) and how do I change color on just that?

Thank You, Leslie
