Linux and its software is constantly under development and the community seems to really be making an effort to ensure that programs work exactly as expected. I often notice little things like glitches or program crashes and I am able to replicate them and I think I should probably submit a bug report or something. Since I am not a dev I have no idea how to do this or where to start. How do I know if its my issue or the programs issue?

For example, Thunderbird 115.1.0 is crashing when I open a specific email. I will put the steps I took to debug it in the comments.
