We appreciate your report. I was able to reproduce the issue. Tapping on the download button crashes the browser.

Tested with:

Browser / Version: Firefox Release 107.1.0 (2015915067-🦎107.0-20221110173214🦎 )/ Firefox Nightly 109.0a1 (2015917611-🦎109.0a1-20221123094429🦎)/ Chrome Mobile Version 107.0.5304.91
Operating System: Samsung A51 (Android 11) -1080 × 2400 pixels 20:9 aspect ratio (~405 ppi density)
Operating System: Google Pixel 3 (Android 12) -1080 x 2160 pixels, 18:9 ratio (~443 ppi density)

Notes:

1. Reproducible regardless of the status of ETP.
2. Reproducible on the latest build of Firefox Nightly and Release.
3. Works as expected using Chrome.
4. Crash report: e19f8db6-f8e3-4905-9dc5-4fe62daecff3

Moving this to NeedsDiagnosis for further investigations.

Going to this url directly will cause a crash http://rgbcampus.sch.ac.kr/_lib/download.asp?downfile=%EA%B5%AC%EC%9D%B8%EC%9D%98%EB%A2%B0%28SW%EA%B0%9C%EB%B0%9C%EC%9E%90%29%5F%EC%9D%B4%EB%85%B8%EB%B2%A0%EC%9D%B4%EC%8A%A4%5F220329%2Epdf&path=board

This appears to be fixed in Firefox Nightly by enabling pdf.js https://bugzilla.mozilla.org/show_bug.cgi?id=1803959, so will be fixed in release once pdfjs is enabled there.

It's enabled in Firefox beta at the moment, and will be available in Firefox release when it reaches 112 (https://bugzilla.mozilla.org/show_bug.cgi?id=1810106)

PDF.js will partially solved this issue, because crash by click-to-download files is not a problem caused by only PDF files. HWP(Hangul Word Processor, which is document format used in Korea), PNG(image file) and any other attachments in this website cause crash.

Example

• Second attachment in this link
• or attachment in this link
• or try png file in this link

Tested on

All attachments in this website tested on Firefox Nightly 112.0a1 (Build #2015936323), 41a42895ed+, GV: 112.0a1-20230228085339, AS: 97.1.0 (Android 12, LM-G820N / Android 13, LM-G900N) but crashed. However, trying Download link on long-press menu may not cause crash. Chrome Mobile 110.0.5481.153 in same device has no problem.

Thanks @lego37yoon, I've filed https://bugzilla.mozilla.org/show_bug.cgi?id=1823467 for further investigation.
