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

Why can't Firefox open .mht email extensions within its default browser? It has never done so to my knowledge. They always point to Internet Explorer or Microsoft Edge.

Often an email may not display images correctly and the ability to open them in a web browser is offered, "If there are problems with how this message is displayed, click here to view it in a web browser." This is certainly a development addition when people view their Gmail from Firefox or use Outlook. Not everybody uses APPS. People who don't want Microsoft Edge watching every move they make have made effective permanent changes in removing the deep embedded PUP by Microsoft.

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.)

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....

"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 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.
