While using Outlook.com email in my Firefox browser, I attach a zip file to send to someone.

They reported that the zip file is empty. This happened two more times.

I confirmed that the zip file that I was uploading from my hard drive did indeed have files included.

I then downloaded the attached zip file from the email in my "Sent" folder. It was empty.

When I tried using "Outlook.com" in the Chrome browser, I did not have the same problem.

I'm using Firefox ESR version 128.9.0, on Windows 10.

(The downloaded empty zip file also had "utf-8" added to the file name - that problem is addressed in other tickets and is being worked on. I am not asking about that.)

"Please create a new version of the browser app that supports the ability to use FileSystemAPI on directories, this is essential for working with a BeatBuddy project and SD cards that are saved on my computer using the online editor."

When i go into file explorer on computer running windows 11 all files were opening in firefox. Even files i scanned into my computer from my printer. I tried to change default to notepad. When i did, all files including images changed to unreadable computer script. Any fix?

Sometimes I need to open XML files on my PC or in a network folder. If I open the file in the first tab in Firefox, it displays a neat and formatted rendering that makes it easier to read. However, if I open yet another tab, it displays a sequential text file that's difficult to read. How can I apply the style of the first tab to all open tabs? I've attached explanatory images (I hope). The second image shows how I'd like the XML file to always be displayed, regardless of the tab's position. Firefox 149.0.2 on windows 11

When viewing a document on Ancestry there are blank squares such that I can read the whole document. This only happens on Fire Fox. When I use Google Chrome I can read the whole document. How do I fix this on Fire Fox.

just trying to remember howto set up Linux with Firefox ,Arduino, and python, python Serial Library plus all the other under lining principles of Ubuntu Extensions , Extensions ! I have a way's to go  !

Suddenly every doc I download or preview is COVERED by something saying I "can now read and sign docs in Firefox" -- and I can't remove this popup -- or even relocate it so that I can SEE the doc I am trying to read.

Is this from my latest firefox upgrade?  Can I undo it?  

The whole popup thing is not even visible, so I can't find something to scroll down and say yes or no. Similarly I tried to play along with it and create a signature. I did that and clicked a "save signature" but again I cannot even see the whole thing so I cannot save it and get out of it. It won't let me take a screenshot so I can show you....

When i try to open a document on firefox or upload/save something I end up with the error reading "The windows file-dialog could not be opened. No file or folder could be selected." This happens on every site. I disabled all my extensions/add-ons and ran the command prompt "sfc /scannow." Is there some way to fix this? Maybe in about:config?
