What version of Firefox are you using? And what site is this happening at? That way others can see if they get the same issues or not.
While it may not solve your crashing issue. If you are indeed using the old EOL Mac OSX 10.10 then the latest Firefox version you can run is 78.15.0esr.
You can download the Firefox 78.15.0esr.dmg here https://archive.mozilla.org/pub/firefox/releases/78.15.0esr/mac/en-US/ other locales are at https://archive.mozilla.org/pub/firefox/releases/78.15.0esr/mac/en-US/
