The Bugbug bot thinks this bug should belong to the 'Firefox::File Handling' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I noticed this too after updating from 101 to 102. On the 28th before updating the browser, files would download with a file extension. After the update, files were no longer being saved with the file extension. Uninstalled 102 and went back to 101 to verify and it seems to be a bug introduced in the 102 release as 101.0.1 doesn't have this problem.

Probably will be fixed by 1773907.

I've been trying to confirm this, but I can't create an account on this Russian website and the issue does not seem to happen for all files of this type. What causes this behavior to appear? Do you have other examples where this happens?

I've tested a bunch of random apk and img file downloads, but all seemed to have the correct extensions after download. (Win10)

The problem is reproduced only on this particular site

Yes, it requests a Russian captcha with every login (not only on register).

Perhaps we could contact through some chat and I could help solve this captcha

In my local network with a domain, RD Web Access with RemoteApp is used, with published applications using Microsoft IIS 8.5.
When opening a page in the Firefox v.101 browser, rdp files are downloaded normally with the rdp extension. After updating Firefox to version 102, RemoteApp files are downloaded without an extension. Everything is fine in Chrome and Edge browsers. When you roll back Firefox to version 101, everything is fine too.

The extension is lost in Firefox 102 on Windows 10. On Ubuntu 20.04 everything is fine

Any easy way to reproduce this issue is go to project gutenburg and download an epub book. It will be saved without the epub extension.

https://www.gutenberg.org/ebooks/68473.epub.noimages?session_id=f8278dd40b5d1ac1078d21601c5f150d9b35b4ad

It ends up being saved as pg68473 instead of pg68473.epub

Works correctly in version 101. 102, not at all.

Now, in 102 you can add a handler "application/epub+zip":{"action":0,"extensions":["epub"]} to handlers.json and it will download with the file extension. But a proper fix rather than a workaround is a better solution.
