Old firefox allowed to for example clear only forms history:
New one forces you to clear forms history together with all browsing history! This is insane as I often cleared forms history (as it quickly became outdated) but left browsing history alone (as it might still be useful in 6 months from now) !
I am not sure what active logins did but now it seems to be completely removed together with offline website data.
For now there is bypass to display old data clearing window via "privacy.sanitize.useOldClearHistoryDialog" in about:config but I guess it will be removed until 2024 ends.
Can you add missing options to new window or separate it into easy and advanced view? Especially clearing forms data alone is essential to me and my coworkers.
