It would be a blocker if it affected every users which is not the case.

Does Firefox hang (not responding) or crash (closing unexpectedly)?
Does it happen with a new profile (see https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles)?
Can you provide the crash ID (see https://support.mozilla.org/kb/firefox-crashes-troubleshoot-prevent-and-get-help#w_get-help-fixing-this-crash)?

Comment 1 answered to comment 3: it's a hang that also happens with a new profile.

I suspect third party software including malware. Check for malware:

Check also the settings of Security software.

It's not caused by Firefox so there's no need to track it in Bugzilla.
