Opening PDFs automatically with Firefox and, without any changes I might make, saving them with the download function in Firefox, actually ruins the functionality and data entry function of that file. Specifically this happens with PDF files downloaded from the (not all that amusing) PDFs from the FINCEN, (US Financial Crimes Enforcement Network). I do not see why and how Firefox thinks it is allowed to change files that are simply downloaded and saved on Firefox.

In other words, it seems that Firefox strips away certain "permissions" and/or "functions" (like built-in lookup, menu or choice boxes). This means that the file so downloaded via Firefox can no longer be used to properly fill in data, or to look up and choose data items within the file. (I see many times that ANYTHING having to do with "permissions" tends to be an intractable and unsolvable problem for software makers & experts, so, if you do not know right away how to solve the problem, it will probably take you several years to figure this out.)

The PDF in question is created by a government agency. If you have ever dealt with a government agency, then you know that they act sort of like Adobe or Microsoft: "They don't respond, or they do respond & say they do not understand, and if they understand, they are either unwilling or unable to fix the problem."

If there is a switch or option within Firefox, which lets me tell Firefox "Save this file exactly like it is received, nothing added or removed!", that would be nice. I just have not found such an option yet, and it would be nice if it might get provided someday.

I will share my browser data, but I am sort of convinced that a detailed question like mine will not be addressed within that shared data.

as soon as i startup firefox it has a quick flash of white before the background image comes up. it happens on new profiles/troubleshooting mode.

i have tried disabling hardware acceleration and it doesnt seem to help.

Firefox is my browser, but I also have Windows Office 365. Every time I open my my gmail account or anything else I have to reset Firefox as my browser. Windows keeps trying to change my browser. I use and have many documents on Office 365 so I don't want to delete it. How can I stop that from happening. I can't disable the Microsoft browser.

Is it gMail or Mozilla that is slowing down the time for gMail to open a new Message? My internet connection is consistently between 200-300 mbps. Also, how to I change the email address on my account? Or should I just start a new account? Thank you.

video downloadhelper is not saving the videos to vdhelper folder any longer. how do I change the folder location for only the video downloadhelper. its going straight to download folder.

thank you for your assistance.

Hi there,

I'm wondering if I am experiencing intended behavior or if I've stumbled upon a bug. I am sometimes downloading files in a staggered manner (i.e., waiting for files to finish downloading before I start the next file downloads). However, any file after the first in that session shows an inaccurate progress indicator in the toolbar which includes progress of the already completed downloads.

For example, if I download two files completely, then start the download of two new files and both sit at 0%, the progress bar for the downloads actually shows 50% completed (2 files at 100%, 2 files at 0% -> Average of 4 files at 50%). I can't imagine this is intended behavior, for I imagine users would like to know how their current downloads are progressing only. This behavior is only fixed when I clear previous downloads, which resets the list to only active downloads, or when I restart the browser and start a new session.

Is there a setting where I can make the indicator report only active downloads?

Any insight is welcomed, thank you.

i used firefox version 144 or 148 and it frequently become whitescreen "but when i put or move my cursor hover, it becomes reload the page again. but it's annoying error bugs

Browser shuts down within 10 -20 seconds of going to a website, and I get a crash report which I have clicked to forwarded each time to Mozilla.

Also have a new error message at the top of the browser that says: "The security sandbox is disabled. Your configuration is unsupported and less secure." (image attached)

Not sure if that is related or not.

I have been on this OS for many months, uploading from the photos library to a website community I'm a long-standing member of, uploading was never a problem until a couple weeks ago. Now, when I go to upload, the link connects only to my "media library" and random photos - I can't select what I need. I had an online chat w/Apple support for the past hour. Tried other browsers (using Firefox) such as safari and brave. Same problem. I created a new user and used other browser. Problem still happened.

Is there a permission issue? Or, should I download the new Tahoe OS and see if that fixes the problem?

Hello, I have multiple devices using Firefox on the same network, and whenever using them at the same time, I get an additional Firefox icon in my doc which will open whatever tab is up on the other device. I was not signed in to any account on either device, yet it is still sharing tab data across devices.

I then created an account and signed in on one device and disabled every Sync option I could find, but still the sharing is enabled over local network. How do I disable this so there is no communication between the two devices?

Device 1 - MacBook Pro (Retina, 13-inch, Early 2015) macOS Monterey 12.7.6 Firefox Version 149.0.2

Device 2 - MacBook Pro 14-inch, 2023 macOS Sequoia 15.4.1 Firefox Version 149.0.2 Local Network access disabled for Firefox in macOS settings

It doesn't seem like this should even be possible given that local network access is disabled for the one device, and neither device is logged into a mozilla account.

Can someone please help me disable this functionality?

Good morning, We are using ver. 150. We have noticed that the landing page for Microsoft 365 does not have the apps tab on the left side of the page. Microsoft has redirected the Office apps landing page to a Copilot centric web page. There is a small Apps tab on bottom left which does not display on Firefox. Anyone have an idea why ?. Thank you,

Martin Reyes

Fox version 150.0 is consuming all available system RAM after the latest update. What's going on? I've been using this browser for years, and this is the first time I've encountered such problems! The tips in optimization guide aren't helping!

I have been using Firefox for a number of years. I use it with Windows 10. My internet connectivity has recently degraded to the point it is no longer viable. It is painfully slow and I keep getting "time out' notifications. I contacted my service provider and they suggested using a different browser. Although I was skeptical, I installed Chrome on my machine and tried it. Connectivity is back to normal. Why? What happened to Firefox? It shows as being up to date. How can I fix it?

What happened: 1) I wanted to create a Passkey for a website and store it in Bitwarden. 2) Bitwarden pop-up opened, but while exploring the options, I accidentally clicked on the option "Use your device or hardware key: Always for this website". 3) Windows Defender dialog popped up with the options "iPhone, iPad or Android device" and "Security key" 4) I backed out of the dialog window 5) I clicked the button to create a Passkey again but going forward only the Windows Defender pop-up appears

The problem: I now cannot create a Passkey to store in Bitwarden on a specific website, because I accidentally clicked on "Use your device or hardware key: Always for this website".

What I've tried that didn't work: - looking through Bitwarden settings - deleting Firefox cookies - doing the same thing in Private Browsing - asking AI and looking through about:config, about:preferences and about:logins, as well as trying to find profile files related to webauth

Found workaround: - creating the Passkey from a different Mozilla profile

I would still very much like to be able to undo the "Always for this website". Is there a way to do that? (Attached images were captured later when recreating the situation.)

I have tried safe mode. No joy, but it has shown plain vanilla FF is the issue, not extensions.

(I'm using a different browser to make this report, so Share Data button is of no use here.)

Mozilla VPN repeatedly gives "authentication error" when I try to log in, I have tried reset but no difference. I am working on Linux Mint with Firefox. Any tips?
