1948488 - Files that ends with % gets their dot before suffix mangled (test%.txt -> test?_txt)

Status: UNCONFIRMED

(Firefox for Android :: Downloads, defect)

Description

[Karel Tóth]

Attachment: screenshot of file download from my webserver

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:135.0) Gecko/20100101 Firefox/135.0

Steps to reproduce:

Download any file that ends with %

Actual results:

The dot between filename and suffix gets deleted resulting in broken filename with no suffix (possibly Percent-encoding problem?)

Nightly is even worse, it crashes instantly

Expected results:

file shoud contain the dot (on PC it works by replacing the % with _)

I think this might get fixed over in the patch addressing Bug 1945705. We can verify this after that lands

I tested on Fenix 141 and the extension is kept, although the original name is not fully respected.

Steps to reproduce

• Open this bug on Fenix
• long click on the following link: test%.txt, and press "Download link"

Expected behavior

The file is downloaded and named test_.txt, as Firefox Desktop does.

Actual behavior

The file is downloaded and named test_txt(2).txt
