Message filter too large to edit, causing it locks upThunderbird

I created my own filter to sort mails by creating a long list of "Move message to folder if From =" rules. At some point, now Thurderbird cannot edit these settings, simply because Thunderbird locks up if I open Filter Rules for this filter, otherwise I could split it into multiple filters.

Is there any way I can edit this filter in text, or fix this issue?
