Firefox 도움말 포럼

This is the error while trying to download Microsoft Office application "Office Timeline" "\??\C:\Program Files(x86)\Mozilla Firefox\firefox.exe." Cannot start or run due to incompatible with 64-bit version of Windows

Hi there. I wiped my C Drive and reinstalled windows 11 on my PC. Completely from scratch.

The first few thing I did is download firefox. I believe in the first boot of firefox, I can download things fine, I installed Ublock Origin add-on and a few installers for the app that I need to use. I can't recall when, but after a few reboot, I noticed that Firefox can't download anything, every download link I click on, the download fail instantly, I can't install add-ons as well.

I tried reinstall firefox, changing download folder target, nothing helped.

Can you take a look please? Thank you!

Hi when i have to download my bios updates i am being forced to use misrosoft edge or chrome none of which i use , so the question is can i use firefox safely thanks . Lee

Tēnā koutou (Hello everyone),

I deleted Firefox to re-install it after playing with profiles and that not working how I wanted it to (yet). I uninstalled the app from the applications and the library on my Mac and reinstalled Firefox. Now when I open Firefox it says that it's up and running but no windows actually open up for me. I have uninstalled and reinstalled it again and it still won't open windows. I have to force quit Firefox as nothing shows up in my top tool bar to even show Firefox as open.

How can I get Firefox to actually install and be functioning on my computer again?

Running (as of an hour ago) macOS 14.5 (was using previous up to date OS when I installed Firefox again.

TIA

I've had Firefox for years and had no problems. An additional Firefox page opened when I opened Firefox and I downloaded it, now it won't open any page. I tried to reinstall but same problem. If i can't fix it I'll have to change browser

I've just updated from 115.04esr to 115.11esr for macOS to the heap of unwelcome troubles. This experience is extremely unfriendly and annoyingly brazen on part of the Firefox developers.

Every time I launch the browser it starts up from its default profile, not mine. I lost access to all my themes, extensions, history, devices and settings as a consequence, and cannot regain it.

All efforts to launch FF from another profile upon opening of a new instance resulted in a dialog nagging me to move the app to /Applications even though I always kept it in a subfolder of my choosing, and intend on continuing to do so. Refusing to submit opens the default new Firefox profile in every instance.

Closing Firefox instances is impeded by a Chrome-like first-after-installation closure prompt asking to have the browser warn me every time I'm closing the browser. Repeatedly rejecting the prompt makes no difference.

The flatly blunt and pervasively arrogant manner, in which the new Firefox forces its way, is off the charts and is unacceptable.

Is there a straightforward way of restoring the old behaviour and telling it to honour my settings?

How can I sign in to Netaddress with the new Firefox update?

I'm afraid that as I am old and female I haven't a clue how all the information below can help. What can I do with it? As I can't access my only email address, I'm not sure how I can follow instructions.

Fingers crossed for some information. At the moment all I get is 'bad request'.

I have a PC that cannot access the Internet. Using a thumb drive, I was going to download Firefox then load it onto the PC. Do you think this will work and if so, how do I put Firefox on the thumb drive (be specific - step by step). Thank you

Firefox automatically updated itself to version 126.0 (64-bit) and it was unable to display any web sites.

First I disabled Mozilla VPN but that did not fix my issue. Next, I disabled Microsoft Defender firewall software to no effect.

Finally I updated the shortcut to Firefox on my taskbar to launch the browser. This fixed my issue.

Hopefully, this will save other users from the same pain.

I am replacing a ten yr. old Dell Desktop with a new HP Laptop. Can you please let me know how to get the new laptop working with my existing Firefox (v125.0.3) with current add-ons, extensions and settings? Thank you for your time !! Rick Perry

Native manifests describe where native messaging browser extensions can be found, as described here:

https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Native_manifests#native_messaging_manifests

Specifically on the MSIX version of Firefox available in the Microsoft Store, what directory does Firefox look in for native manifests?

The problem I need to solve is that I need to place a native manifest in a location where Firefox can see it, specifically in the new Windows MSIX installer. This seems to be reasonably straightforward, if I can confirm where that is.

Hi Lots of my files on Mac have converted to Firefox (which I don't use) and will not open either in Mac, Adobe or Firefox. They are showing in my icloud drive but I cannot open them. And I REALLY need them as they are the source files for a website. I have no idea why this has happened, but would love some advice on how to fix it. I don't ever intend to use Firefox so not quite sure how it happened. Many thanks
