Diễn đàn hỗ trợ Firefox

I'm trying to open Firefox on my computer,it tells me that it has crashed.wjats going on.need a answer before I take things further.as I can't access data without firefox.failure to repair will result in legal proceedings

I know that this is not a new issue, but it's a recurrent issue that keeps coming back. When I install a Firefox update, MacOS (15.5 at present) often gives me a popup that says "Firefox is trying to install a new helper tool. Enter your password to allow this."

But I don't ever want to enter my password to install a tool that doesn't identify itself. I view Firefox as always being at the forefront of security, but asking for a password for a tool that's not identified is a security risk. Maybe it's MacOS that refuses to identify the "helper tool", but it's a Firefox problem. It's unacceptable.

In today's update, Firefox won't work at all after I hit cancel to the password dialog. I have to Force Quit it. I'm going to have to delete Firefox and reinstall, and hopefully that will work. But I shouldn't have to do this. It's unacceptable that this keeps happening. (If there's some weird configuration issue at my end, I think Firefox should be flexible enough to deal with it.)

I don't know what version of Firefox is generating the problem, because it's currently unresponsive, since I haven't entered my password to install the helper tool. (I'm writing this in Safari.)

(In the attached image, I blotted out my username.)

There always seem to be daily issues, "Mozilla Not Responding". We clear out Cookies, Cache, history, etc. throughout the day. We've had to shut it down and restart the computer. Oftentimes, the system just shuts down.

For the last few weeks, we have an unknown popup from Mozilla, "Unable to load XP.com". Not sure what this may be or why this popup suddenly started. We close it and pops up periodically several times in a day. I am attaching a screenshot of the image.

Thanks

Last month, this issue occurred on my win11. This question is the same as the one mentioned at here: https://support.mozilla.org/bs/questions/1222579 it's still unresolved. Can anyone help me?

I always use Firefox Private Window when I go on the Internet. Today, while I was on Fidelity.com, I was suddenly logged out. When I tried to go back to Fidelity.com using Firefox/Private Window, a dialog box on Microsoft Edge appeared asking me to: "Choice: #1 Do you want to make Firefox to be your default" "Choice: #2 Not Now". Which ever I choice I choose, Microsoft Edge will appear with the two above choices. This has been happening repeatedly for several minutes now, so I tried to reach Firefox Support.

My main problem is I cannot access Firefox / Private Window anymore since I was suddenly logged out of Fidelity.com.

Would you please fix this problem. Also, I already selected Firefox to be my default browser long time ago. Why am I being this question every time I go on the internet using Firefox?

Hello, I’m having trouble getting Firefox to work properly on my computer. During installation, the setup process becomes very slow, and once I manage to install it, Firefox hangs or becomes unresponsive within a few seconds after launching.

My system details:

Operating System: Windows 10 64-bit

What I’ve tried so far:

Reinstalling Firefox Running in Safe Mode Clearing profile data Disabling antivirus temporarily

None of these steps solved the problem. There are no specific error messages — the browser just freezes, and I have to close it via Task Manager.

Hello,

i was trying to check my apparmor stuff because of the warning on Linux. Now i tried duck.ai to instruct me , but created more damage than anything else. It said to set firefox in enforcement mode, now it wont start (well im using Firefox right now in complain mode)

How do I fix this problem that everything runs normally and safe?

I installed Firefox on my laptop, but I am not able to open the browser by double clicking the icon. Do not understand, why it is happening on my Dell laptop. Please suggest. Thanks.
