Debug symbols server issue

Hello,

I'm willing to debug an older release of Firefox (ver. 98.0). In order to do that, since I don't want to compile, I wanted to download the debug symbols from Mozilla's symbol server. I followed the documentation provided about this service but I still can't make the server give me something else than 404 Not Found.

From what I understood, I tried fetching symbols using this URL : https://symbols.mozilla.org/firefox/firefox-98.0-Linux-20220304153049-linux64-mozilla-release-symbols.txt

But the file doesn't exist. The /firefox sub-directory doesn't exist either.

How do I properly use this service ? Thank you for your time,


Tim

Thank you for your response,

Yes I have, but I'm struggling to understand how to provide version number to this API. It only seems to be possible to provide a debug ID, and I don't know where to find one that corresponds to the version I'm trying to debug.

One thing older browser support files are most likely removed from aging. And the 404 you saw tells it's no longer available. Is there a reason your not using the latest version. Older browser is security risk and putting your data at risk.

I'm trying to debug Firefox 98 to analyze a vulnerability that exists in this version. I'm therefore aware of the risks implied by keeping an old version of Firefox.

From what I understood, if I get a 404 error it might be because the symbols are removed over time, but Firefox 98 was released on 2022-03-08. How long does it take before symbols are deleted ?
