A very useful addon, as it saves valuable time with long threads, on a browser. This should have been the default for a better UX.

A very useful extension available for Firefox as well as Chrome.

It would be excellent if the author add temporary disable feature to it.

Nice job!

Really helpful. Gmail default order sucks

Does what it says! I wish this were a built-in feature, but I'm glad this addon is here to offer it.

Would give it five stars but the addon is missing the obvious functionality of switching between reverse/non-reverse mode from the addon icon (or even better: also in some obvious place above the thread inside gmail). Users *can* switch by enabling/disabling the entire addon, but that requires a few more mouse operations than what is convenient.

I am using the latest Mozilla Firefox and the latest Gmail.
This extension works as described,
HOWEVER
Printing does not work if the email series is longer than one page of print.
What happens is that a full page of blank (with a top heading email line) is printed and then a second page is printed and the expected subsequent pages of print are missing.
This printing error does not occur with any other printing I am doing.
A scanned example is available upon request to the author.

Very nice add-on. It took very little time to get used to it, but the reverse order makes more sense and is consistent with the inbox ordering. Impressed that this is just CSS.

This add-on got deleted when setting up my new computer. I forgot the name of this add-on but was so happy to find it again. Using Gmail without this add-on is a huge pain in the ....

This add-on makes Gmail more logical and useful. Thanks so much to the folks who made this add-on.

Much more readable conversation view. Highly recommended.

Beautiful! It has solved my problem in an extremely simple way!

Fantastic, just what I and surely many others have been waiting for. Sorting from newest to oldest is so much easier to use - no more scrolling to the bottom of the conversation. Should be in the gmail settings of course, but gmail/google is clearly stubborn, so a big thank you to Tomasz!

So simple, so brilliant!
Firstly: Especially useful with splitted pane (from Labs), so as you see threads as newest on the top.
Secondly: e-mail nature seems to be appending new content at the top of previous content, so reading is reversed.
