Works, but not as good as expected Noté 3 sur 5 étoiles

This AddOn is a very good idea - thank you! But may be it needs an update.
Despite the Mozilla AddOn-Website says, it is compatible with TB up to 31.x, I tried it with TB 48.4.0 on Win 10pro:
In IMAP-Accounts it works quite slow and does not update the listing directly, so the old header is shown instead of the changed one. I could not find a rule yet when the maillist will be updated.

("header tools lite" do the same job quicker with direct update of the listing. But HTL is a bit dangerous, because it can do too much... In IMAP folders, HTL produces a copy of the message, too, but keeps the original date.)

@Kiwifagan: To clean the subject from "Re: Fwd: Re: ..." you may use the AddOns "CleanSubject" or "Subject Cleaner". They do it automatically.

Has problems with Gmail IMAP Noté 3 sur 5 étoiles

Using this add-on with Thunderbird 38.6.0 on openSUSE Linux does not get along with IMAP access to Gmail.

I've enabled Googles "Access for less secure apps" to that IMAP is still able to work.

I tried using this extension both with and without "Only local changes (will only change local Thunderbird index database)" enabled.

In both cases, editing an initially blank subject generated a new copy of the email on gmail. However, in both cases the subject line was still blank. (The email had a PDF attachment, if that matters.)

An interesting side note: When viewing the new copies of the original message via, the displayed date was unchanged from the original. However, when looking at the inbox message list, the message thread (the new copies are threaded onto the original) shows the date and time of when the subject was edited!

The only clue I have is that when I look at the headers there is an "X-EditEmailSubject:" tag with the datestamp of when the subject was edited. This may be a false lead, as gmail could be dating the new message internally from when it was inserted via IMAP.

If I only needed the edited subject to show up in Thunderbird this wouldn't matter. But since also access my email via my phone and on other PCs, I really need the change to propagate back to Google.

The need to edit the subject line of existing messages is often critical, and this extension should be a standard part of Thunderbird. It's a shame the gmail doesn't seem to get along with this at the moment.

Suggested update to this Add-On Noté 5 sur 5 étoiles

Like many have said previously - missed the ability to change subject heading so as to correctly align search, archiving.
This Add-on is great.
A very nice addition would be the ablity to process a bulk subject change. select a mail box the enter the search string and the replacement string then process all email. e.g.I subscribe to Computer industry forums where questions are asked and many answers are given; the subject becomes messy with all the RE: FWD: R; {Disarm} rubbish that gets added to the subject. Removal of these items would greatly enhance the reading.
Many Thanks.

Wished, this add-on would be available fo Seamonkey as well Noté 3 sur 5 étoiles


would it be possible to make this add-on available for Seamonkey (by default) as well?
My Antispam Software declares sometimes Emails als [Spam], but it isn't. Therefore I would be happy to have a possibility to remove this. But I use Seamonkey and not Thunderbird.

And I agree Michael36, this add-on (feature) should be Standard in Thunderbird or Seamonkey!

Editing IMAP header creates new copy Noté 4 sur 5 étoiles

In common with some other reviewers I need to edit the header of the IMAP email so that the change to the subject appears to other users and/or mail clients. I can do this by turning off the "Local Only" option, however it then creates a copy of the email with the new subject ... and doesn't delete the original.

Would love change in original sent email Noté 4 sur 5 étoiles

I'm not exactly sure what this does, but is there a way to change it in the original sent email subject header? I hate when people change the subject in a thread of emails. I wish I could change it ot organize them. Thanks.

Very useful Add-on, but confusing Options Noté 4 sur 5 étoiles

This add-on is a great addition to Thunderbird. I wished it were ported into the default builds (see bug 91106).

The only thing I would like improved is the confusing Option for "[x] Only local changes (for IMAP)". It mentions "local" and "IMAP *together*, but the help text mentions "local TB database" and "IMAP compatible" as two SEPARATE and seemingly opposing options. I find that seeming contradiction confusing. A less confusing and more elaborate explanation for novices would be VERY useful. Five stars if this issue were improved.

Anyhow, thanks for this great add-on.

Simple but cool extension! May I ask you to add one option. When subject of received email is empty, this addon set some text predefined by user. Anyway, great job!

Brilliant. Noté 5 sur 5 étoiles

Brilliantly simple, and solves one of the most annoying aspects of email correspondence: receiving an email message with a subject that does not match. Nice work!

Stupendous! Noté 5 sur 5 étoiles

This is stupendous! I always wanted this! This is for version 2.02. Just FYI for y'all - this only changes the subject of the message in the main message pane. If you look at the subject in the header bar of the message, it is unchanged - which is good, because it reflects to you what the sender named it. However, there should be an option to perform this step as well. Also, in an english-reading browser, the "about addon" link in the addons window links to the french not the english - this should be fixed.
