No. Thunderbird removes all localised prefixes and exclusively adds "Re:", see: https://searchfox.org/comm-central/search?q=%22Re%3A+%22&path=mail&case=true®exp=false There are two decisions to be taken here: - Use case-insensitive matching or not. If not, we need to start off with "Re,RE,re,rE", see: https://searchfox.org/comm-central/rev/2006bce43f7350f93c37e18a136e149f9a7ffb6c/mailnews/base/util/nsMsgUtils.cpp#547. I think that case-insensitive matching is fine. - Whether to remove the said code in enigmailMsgComposeOverlay.js#3933-3944. The reviewers got removed again :-(

No. Thunderbird removes all localised prefixes and exclusively adds "Re:", see: https://searchfox.org/comm-central/search?q=%22Re%3A+%22&path=mail&case=true®exp=false EDIT: IOW, It wouldn't make sense to show "Aw:" in the header pane and "Re:" in the thread pane. There are two decisions to be taken here: - Use case-insensitive matching or not. If not, we need to start off with "Re,RE,re,rE", see: https://searchfox.org/comm-central/rev/2006bce43f7350f93c37e18a136e149f9a7ffb6c/mailnews/base/util/nsMsgUtils.cpp#547.
