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?

Hi there,

On Firefox, I'm experiencing "momentum" scrolling where, when I scroll using the trackpad, after I lift my fingers off, it keeps scrolling for a bit.

This is not the same thing as smooth scrolling. Disabling smooth scrolling does not disable this behaviour, and I use smooth scrolling on plenty of programs without it experiencing this "sliding" "momentum" on any of them except Firefox. I've also used Firefox before with trackpads without experiencing this.

How can I disable this?

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

Hi, on my current Firefox setup, I have a search engine shortcut in my Top Sites on a New Tab page. It's a quick one for Amazon, I can't figure out how to add others though. I saw reference to it in this old support issue, but I can't find how to do that anymore.

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

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 ?

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?

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.

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?

Every time I open a youtube video in fullscreen, firefox crashes. `about:crashes` says "No crash reports have been submitted."

Some information about my system:

• Firefox version: 122.0.1 (64-Bit)
• Macbook Pro M2
• MacOS Sonoma 14.3.1

If there is a way to get more information that you would require (like logs) please describe how I access them, so I can share them.

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!

I use a public computer often, and I would like to use certain customizations while remaining anonymous. Rather than going through and clicking a bunch of checkboxes, I decided to have a hot key combination to enter in order to obtain my desired options. For example, I want to allow new windows to open normally, I want to choose where files are saved, and I want to turn off Firefox's recommendations. The underlined hotkeys are, respectively, ALT+W, ALT+A, and ALT+R ALT+F. So rather than a bunch of scrolling and clicking, I could just type ALT+WARF, and get the options I want quickly.

However, pressing the hotkeys while in the settings does not seem to do anything. In particular, pressing ALT+WARF only succeeds in pressing the ALT+F, which opens the File menu. Pressing these keys without an ALT key sends them automatically to the search bar -- which is also not what I want. Pressing ALT+SHIFT focuses in on the checkbox -- but does not press it. For example, ALT+SHIFT+W focuses on the checkbox, but I still have to click SPACE after it to press it.

Is this a bug? If not, how can I make the underlined keys press the respective checkboxes?

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?

Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

When I close a private browsing session and open it again, the given permissions for cross-site cookies are still there and Google remembers my last search results from the last private session (in the suggestions below the search box)!?

Nie mogę zalogować się na konto Gmail poprzez stronę www.google.pl w przeglądarce Firefox. Przy próbie zalogowania się przez www.google.pl pojawia się komunikat Bad Request Error 400. Ten sam problem występuje, gdy muszę potwierdzić logowanie do innych stron internetowych za pomocą konta Google. Po prostu nie da się nigdzie zalogować. Ten problem nie występuje w innych wyszukiwarkach. Moderator Firefox odpowiedział -"This does not sound like an issue with Firefox, but is something that the Google support team should be able to help you with" Na stronie www.google.com pojawia się ikona zalogowania, ale i tak nie wszystkie usługi związane z Google są dostępne. Niedostępne są wtedy — Google konto, Google Play, Gmail, Meet, Chat, Dysk, Kalendarz, Zdjęcia, - to tylko te najważniejsze niedziałające." Pliki cookie są włączone. 25.12.2023 ten problem nie istniał. Próbowałam przywrócić Firefox na wcześniejszą datę instalacji, ale to nic nie dało. Rozszerzenia i wtyczki odinstalowałam. Problem niestety pozostał. Bardzo proszę o pomoc. Pozdrawiam Bogaczewicz Bogusława.

THANK YOU

That's a very odd bug. When I select an image from paint.net selection tool then copy it on firefox on whatsapp web or google docs, there's a 1 pixel line on top of the image. The line gets literally incorporated into the image. If I download the image, the black line is on top of it replacing the first row of pixels.

This does not occur on Edge, and it also does not occur when I try to paste something from other image editor, like mspaint. Firefox version is 122.0 and paint.net is 5.0.12. This bug just won't occur if I don't use firefox or paint.net, and it only occurs when both are present.

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
