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.

Hi!

I am getting messages that I am blocking ads for many of my internet requests. I had never received these before but all of a sudden I started to get them. I have tried a number of things but nothing works.

I am running Windows 11 and do not have any Ad blockers.

My previous email provider Eclipse has ceased hosting. I found how to update sync email by adding another and promoting. I can't do this as the system sends a code to my no longer exisiting email address. How to get around this. I have a gmail address, iandtryagain@gmail.com

All of a sudden I am finding that Firefox will not connect me to certain websites such as Walmart, Doordash and even Firefox itself. It looks like it's trying to but it just gets stuck. What's causing this and how do I fix it?

1. There used to be a choice in settings for Firefix mouse control to be optional. It is no longer available and apparently FF has created default mouse behavior.

The mouse behavior has become errant in a variety of ways. It interferes with everything online and started doing the same on the desktop.

The wheel is configured for three lines at a time on desktop. I do not want the mouse wheel to be doing anything else. I want either or both mouse buttons to open menus and function normally with links, copy and paste.

When looking in about:config the extensive number of configured mouse defaults is shocking. it is impossible to determine how to disable or delete any of them.

It has become impossible to scroll with the wheel and the scrollbar because the mouse jumps all over the page as if possessed.

It is impossible to scroll 3 lines at a time with the wheel, instead the mouse goes up and down and jumps to the top. Changing the number of scrolling lines on Desktop and in about: config so they are both 3 did not solve the problem. Tried changing both to 5 . . . no joy.

Expandable menus no longer open on some websites.

It has also become impossible to us the scrollbar effectively, instead the same behavior manifests as it does with the wheel - the mouse is jerky, going up and down and jumping to the top of the page, unpredictably.

Either way the mouse gets stuck moving up and down. After having successfully scrolled past where it was previously it returns, repeatedly, to the same previous lines each time I try to scroll further - in an endless loop.

If the mouse does functional, briefly, then half way down the page it starts misbehaving again. I already replaced the mouse several months back when the problem started, however, it was not constant. Then it started again with the new (usb) mouse. (Yes, I've cleaned it. No it is not worn out yet.)

2. Via a search I did find a list of adjustments to make in about:config while learning unexpected mouse behavior had become a common problem. I made at least 20 adjustments, and amazingly, there was no longer a problem! Smooth scrolling, no problems. However, after using the browser, closing and opening it numerous times, the errant behavior returned.

3. If there is no way to completely turn off FF mouse control, or use about:config to disable it entirely, then what is the last FF version that allowed saying "no" to what used to be optional mouse control, so it is possible to change back to it? If there is no other way to solve the problem, that should do it.

Any suggestions or solutions appreciated.

16 GB memory, 500 GB SSD. (chose to not install Windows 11 version 23 onward - so in the 22 gray zone that is both a windows 10 install and a windows 11 install - this is the windows 11 install).

I rarely turn my laptop off, when I'm not using it I put it into sleep mode. Firefox absolutely hates this though, and after a few days it will slow to a torturous crawl. Everything becomes horribly irresponsive, feels like nails on a chalkboard. It can even get to the point where it will randomly delay my cursor in Windows 10 itself by 10 SECONDS along with some bleed into other programs while switching between them. Fully closing Firefox then re-opening it will reset the issue, starting the timer again, but I hate doing this because I have doing that set to log me out of various sites which I then have to re login to, letting the torture boil until I give in. This has been my Firefox experience on laptop for at least 5 years now. Other forks of Firefox have this same issue.

I am leaving Firefox in the torture state currently to troubleshoot here. Currently the memory usage on Firefox is 6GB at 54% of my total ram, which is being used at 84% total. Total CPU usage is 23%. Wrote this on my desktop for my sanity so that's why there's no troubleshooting information.

When signing in to my sky account via Firefox I am not receiving the 2 step verification code on my phone , I had been receiving the code with no problem until 2nd April 2026 , I have not made any changes to my phone or to my firefox account or browser , when I access sky via google I receive the 2 step authentication code via my phone with no problem it is extremely frustrating as I use Firefox all the time

The latest Firefox update installed itself upon opening Firefox. It did not include my personalization. Specifically: - The color scheme was changed to from white to purple making the screens hard to read. - The right side window that had my bookmarks sorted into folders has disappeared. So, how do I get my color scheme and book marks menu back?

Windows 11: I have file download setting set to: "always ask where to save". I choose the location and folder when the save file box opens. The document is saved in the location I chose BUT it also saves to the desktop. How do I stop a duplicate download from saving to the desktop?

Thank you

I cannot play games plus will now lose my 7M for each daily login and the four spins I can do every four hours

I cannot find a date associated with the history entry, I can search and the site link is shown but not date. I can sort by date but no dates are shown. Where is the date I visited the site?

I recently switched operating systems from W11 to Linux (Zorin), and installed a new copy of Firefox. I rely on local web pages I have written for some of my work, but the new copy of Firefox does not find the file. For example, when accessing an image, e.g., file:///magrathea/dmpase/home/index/coastal24.png, Firefox gives the message:

File not found Firefox can’t connect to the server at local file What can you do about it? Check to make sure you’ve typed the website address correctly.

The address is correct, that is, the file resides at: /magrathea/dmpase/home/index/coastal24.png and the user does have permissions to read the file. I've tried adding up to five '/' characters to the beginning, and I have turned off all of my installed add-ons, but without success.

An apparently related problem is that double clicking on a '.htm' file also changes the address, for example, from '/home/dmpase/Desktop/index.htm' to 'file:///run/user/1000/doc/f07a8988/index.htm'

And finally, the "Brave" browser is able to read the files with no errors.

How do I fix this for Firefox?

WHAT THE HELL IS MOZILLA DOING?!?! THEY KICKED ME OFF MY PROFILES AND PUT ME ON A DELETED ACCOUNT. I've been asking for one month and no one ever responded. This company is trash and wont even provide support for their mistakes. Some even replied to me making fun of my situation... The worst service I have experienced....
