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.)

On my site, I am not able to view images. I can on other browsers, but not with Firefox (Developer Edition). I have tried new profiles, private window, etc and images still do not display. Images DO display on most other sites, and this is my first time encountering the issue. Images show on every other browser that I have tested. The url to the website is https://www.nohacks.org

Hello,

Since the new version of Firefox desktop 137.0.2 my xslt is no longer interpreted correctly. I use the xpath-function document to load external xml documents in my stylesheet. But no document is since the new version loaded. Also with links to intern pdf-documents I receive the error "file not found".

I saw that in the new version there was changes in xslt. Is my problem a bug or may be exists there a workaround (in changing settings)?

Thanks a lot for your answer. Regards, Tomateus

I run a blog and upload items daily, but EVERY. SINGLE. TIME. it opens the Desktop folder and not the last one that was used which is the downloads. So every time I have to point it to the Download folder for the file I want to upload. How do I stop it from doing that it's really annoying.

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....

Hello, After installing Firefox 137, Windows shortcuts stopped working within Firefox: for example I am on Google Mail writing a new email. If I want to attach a file to my email, I click on the classic paper clip, it opens a windows dialog box to browse my files and folders. Up to now, if I did double-click on a shortcut (a .lnk file) it would follow the shortcut (like if it was a folder shortcut it would open the corresponding folder) for me to choose a file ... As of 137 it attaches the shortcut, and tries to attach the whole content of the folder ! I tried the same operation on Chrome, it works ok. I tried the same operation on a different service on Firefox (Mattermost) I have the same problem, so my guess is that the problem is with Firefox 137. (this has been working properly for the last 10 years at least). And I made the test on MacOS, no problem, it's really with Firefox 137 on Windows. Anybody else seeing this ?

In the latest version 137, I've detected an error when uploading/attaching any file to a website. The error occurs when browsing files on the computer. When you click on a folder that's a shortcut, Firefox attaches it as a .lnk. Double clicking on the folder doesn't work To fix this, I have to right-click and open it. That way, I can navigate to the files in the folder.

I am 80 years old, and not a tech genius. Whenever I go on the Xfinity website to print a bill, I get a "Something Went Wrong" message. If I use Edge, I have no problem.

I frequently make screenshots using Alt+Shift+4. The screenshot appears in the lower right corner and I used to be able to grab it with the mouse and move it into a folder, email, slack, message etc.

After the newest upgrade, this isn't possible anymore. I need to wait until the preview disappears, go into my folders and move it from there, which is very cumbersome.

When trying to use the new command + V shortcut, it copies the link to the dropbox but not the actual image.

How can I keep moving screenshots where I need them?

Description: After upgrading to Firefox 135, we are experiencing an issue where file uploads using the multipart/form-data format fail to complete successfully. The issue occurs when submitting a form using the jQuery Ajax method ($.ajax) with enctype="multipart/form-data".

Key Observations: • The same implementation works fine in Firefox 133 and other browsers (Chrome, Edge, etc.). • Our SSL certificate is rated B on SSL Labs, with TLS 1.3 enabled. • The issue persists even after disabling browser extensions and clearing browser cookies/cache.

Environment Details: • Browser: Firefox 135 • Form Submission Method: $.ajax({ type: "POST", enctype: "multipart/form-data", ... })

API Response - 520: Web server is returning an unknown error

We suspect this might be related to a security policy change in Firefox 135 affecting file uploads. If anyone has encountered a similar issue or has insights into recent changes in how Firefox handles multipart/form-data, please share any possible solutions. Would appreciate any guidance or workarounds!
