Comment 3 for bug 2048792

Hello,

The reported version of Firefox (100.0.2) is rather old at this point, and could be a potential security risk: to my knowledge, Mozilla don't backport bug fixes to older versions of Firefox (except for the current Firefox ESR series), and many security and non-security related issues have since been reported and fixed in later Firefox versions. Thus, I would highly recommend considering updating your system packages, including Firefox, to latest versions and then try again - your issue may already have been fixed in a newer version of Firefox.

If the issue still persists with up-to-date Firefox and system packages, I would echo Seb's recommendation of reporting the bug upstream at https://bugzilla.mozilla.org, and include a performance profile per https://profiler.firefox.com as well.

Searching through Bugzilla, https://bugzilla.mozilla.org/1733377 came up, but I'm not sure whether or not it's the same issue. Please feel free to comment on that and/or open a new issue.
