brings up accounts that are all mixed up -- for example matches a name of a gmail account with an email address of another email host. verified all the info is named correct in the outgoing smtp area of tb3. (mac os x.6.2)
in fact out of the 6 accounts i have - it only has the First 1 identified correctly - the rest have the wrong email address matched up to the account name.

Very simple and useful. It mixes up my account names and accounts in the settings window, but if you know the right order, you can guess. When writing an E-Mail everything is fine again.

Great. Simple, useful, unintrusive. Thanks.

Just a suggestion: add a "no color" option (so that one of the identity could be set up as not having border color).

Excellent addon - has saved my behind several times. Catching things by color is much quicker than reading.

If I could ask for one feature, that would be to be able to use patterns in the email addresses assigned to colors, rather than simple account IDs. Reason for this is that I use the Virtual Identity addon, which lets one use multiple variations of an address with a single account.

For example,

userid@domain.com
userid-mozilla@domain.com
userid-parents@domain.com

and so on. In this case, I would want to match up

userid*@domain.com

with a single color.

Thanks -

Great extension and very simple to use. I too am very surprised this is still in the sandbox. Highly recommended for anyone that doesn't want to accidentally sent mail from the wrong account!

BorderColors is a very light extension that adds a configurable border to any compose window, colour-coded to remind you what will appear in the From: field.

Configuration is trivial, one just has to assign colours to each email account; after this, the extension is failry unobtrusive but effective: the thin border is a bright alert, in case you are using the wrong account.

Extension has been working fine for months now, I'm surprised is still in the sandbox.

I use three accounts, personal, work, and sports club, and I don't want responses coming back to the wrong one because I was too dozy to check before sending! I tried other add-ons, one of which argued with existing add-ons and another that just added more words to read and ignore without helping.
"BorderColors" is brilliant because it's visual; associate each account with a colour and you instinctively know which one you're using.
Only problem I found in ver. 0.1 is that in the options box the account names and email addresses don't correspond. Fix that and it gets five stars!
