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.

Dear Firefox Team,

It has re-occurred to my Firefox Browser of the latest version of 115.30 with some websites which I have recently visited however which have appeared 8 grids of blank or white pages again under "Recent Activity" as attached with the image for your technical troubleshooting suggestion.

Those 8 grids of Recent Activity in the older version of Firefox browsers used to have shown colorful graphics or images representative of the recent websites I visited in the recent past.

May I know what I am supposed to do to recover those graphics or images?

Kindly offer any suggestion or solution?

Thank you for your kind attention.

Keeper password manager stopped working on Firefox about a month ago. It is the Keeper auto fill that is not working. I have exhausted support from Keeper. They cannot explain it. I have removed and downloaded Keeper and Keeper auto fill about 10 times to no avail. It works on Chrome and Safari, but not on Firefox. All devices and accounts are up to date with the latest versions. I am having to stop using Firefox for now because it is such a hassle to fill in all my passwords. If I can't solve it, I'll have to try a different password manager, or stop using Firefox.

Hey , I’m hoping someone here can help me figure this out. Firefox has been acting weird for the past couple days. A couple of my tabs keep reloading themselves for no reason. I didn’t change any settings, no extensions were added, and there are no error messages. I already tried clearing the cache and restarting, but it’s still happening.

Has anyone run into this before or know what might fix it? Thanks in advance . Matthew Mahgerfteh

I want to delete/remove subject folder from my Windows 11 desktop. I did not create this folder; it suddenly appeared after I reinstalled the Firefox browser. These are the steps I am using in the deletion process: I right click on the folder and click on the delete icon. At the top of the window it says "Folder Access Denied." (Image 1) Below that it says, "You'll need to provide administrator permission to delete this folder." If I click on the "Continue" button, then the error message changes to "You require permission from OWNER/(me) ... to make changes to this folder." (Image 3) The permissions for this folder listed in the "Security" tab lists three groups: 1. "SYSTEM," 2. "F... S... (...@ Outlook.com)" and 3. "Administrators (Owners/Administrators)." All the foregoing have full control and modify control for this folder. The "More details" seen in Images 1 and 3 is grayed out so I cannot get any additional information. How can I delete this unnecessary and data hogging folder? Thank you all very much in advance to all that chose to respond.

I'm in Troubleshoot mode, no extensions running, and tabs are crashing again. Here are crash report #s for today:

Is it coincidence that this is happening on my Windows 10 machine since MS support for Win10 officially stopped? Gosh, I just don't know! grar grar grar

I have a new computer and I want to sync my Firefox account but the Sign In button next to Sync and save data options are missing from the browsers in both devices.

How do I fix this issue?

My bookmark features has stopped working. When I click the star, it does not turn blue and I cannot bookmark anything. Is there a fix? I have stuff in the bookmark area and would not like to loose it.

I keep getting this message when I try to sign in on Firefox. Chrome let's me sign on but i much prefer Firefox. Any suggestion? {

How can I get all Firefox settings as a simple table? I am sure that is how they are kept by the program, somewhere outside the Firefox UI. Are they kept in the System Registry? It would sure make troubleshooting & continuity easier when moving to new devices/CPUs.

I downloaded firefox desktop for my imac 27" none of the passwords I had on file would work so I changed the password and tried it. It appeared to work but after a while the incorrect password came up again. I continued to try using the code you sent via email several times and even though it appeared to. accept the password it still rejects your code. I have tried both caps and lower case characters but it still rejects the login

I just purchase a new computer. Windows 11. When I first set it up I tried to log into Yahoo.com mail on 4 different browsers. None of them worked. Either had the error message of "1. Disable Ad Blockers 2. Enable Java Script". or "something went wrong". I disabled the ad/pop up blockers but cannot find settings for Java. I am not having trouble on any other device, nor with any other website.

I restored the computer to factory specs since I had hardly anything on it. That did not work either.

Recently the shortcuts on the Firefox browser started being greyed out and not accessible. Using iOS ver 18.7.2. Tried lots of different things to chess them but no luck so far. A major impediment to usability

Thanks
