This is a most excellent place for technology news and articles.
That's not normal. You should go to the support pages and see if there is a fix. And it could be an addon causing the issue, not FF itself. I had that issue many years back.
I did check the about:crashes page and it showed me that it seems to be related to "speechd init" and the crash itself is being linked with https://bugzilla.mozilla.org/show_bug.cgi?id=1794057
Having said that, I just disabled narrate, so maybe it goes away now.
