Running Thunderbird 128.1.1esr (64-bit) for Linux Mint (mint-001 - 1.0) on a Linux Mint 22 Wilma system. When I click Message Filters and then Filter Log, I do not actually see the filter log, only a check box to enable it, which is already checked" - same as https://support.mozilla.org/kn/questions/1438189 I noticed it today and, as I normally check the filterlog on my primary (POP3) account about once a week, it would appear to have only started happening recently. I checked the filterlog.html files for all of my accounts - they all looked OK. Went through TB Clear Log, Close for all of them, quit TB, reload TB, same as before. filterlogs not showing. Cleared 'Enable the Filter Log', quit TB, deleted filterlogs from profiles, reload TB, enabled filterlogs, quit TB, filterlogs had been recreated in profiles by TB. Reload TB, moved some filtered mails back to inbox, ran filters again, they had been moved from inbox to deleted, showed when filterlog.html viewed in Firefox but still not showing in TB via Message Filters and Filter Log. All help greatly appreciated.
