download rmd 1.4.6 from addons.mozilla.org
It took awhile but I finally got around to submitting version 1.4.6 of RMD to addons.mozilla.org.
RMD 1.4.6 supports Firefox and Thunderbird versions 1.5 through 2.0.12 on Windows, OSX and Linux.

https://addons.mozilla.org/en-US/firefox/addon/2131
(And just a reminder that RMD will not be updated to support Firefox 3).

Thanks for this nice extension. It´s useful to overcome misconfigured certificates. A great improvement might be to extend it to untrusted sites in general. This would allow me to blacklist a certain CA I do not trust. Is it possible to include this third category ?
Thanks in advance

Hi Mero, glad RMD helps. I’m not sure I understand your blacklist question. Doesn’t the Certificate Manager in Firefox / Thunderbird provide this already?
Cheers,
A.

I wanted to update to RMD 1.4.6, but I am getting a dialogue telling me:
“Remember Mismatched Domains” could not be installed because it is not compatible with your Thunderbird build type (Linux_x86_64_gcc3). Please contact the author of this item about the problem.
So hereby I am telling you ;-). I am using Kubuntu 7.10, Thunderbird version 1.5.0.14ubu (20080306).
Thanks for your hard work.

Hi again Kees,
Sounds familiar ;-)
Could you confirm that the build type your Thunderbird mentions is in this list:

Cheers,

Andrew,
First off, allow me to thank you for the wonderful extension! It has been a real time saver.
I test FF 3.x a few months ago and was horrified by the awful state of cert handling. They’ve managed to make it HARDER, not EASIER to manage sites with certificate problems. It’s damned insane! Yes, it is true that security exceptions do allow for some RMD functionality. However, the anal-retentive security assholes over at Mozilla decided that they would completely remove the nice little gui dialog which would prompt you for your choice of how to cert problems. Now, it just gives a hard error and refuses to continue. No options, nothing! I don’t WANT TO HAVE to go crawling around configuration options to add a site to a whitelist, I want a prompt that will ask me what to do ONCE and then do it for me! I’m sorry for being so angry, but I’ve felt like things have been going downhill for awhile now. Anyways, I was hoping that a gecko 1.9 version of RMD might provide the missing prompt to add the site to the security exceptions list (iow, revert the retardedness introduced by the over-zealous security morons). Please, this is a *major* problem for gecko 1.9 since it also behaves the exact same way with any certificate it *feels* is invalid, including self-signed ones!! Yes, that’s right, self-signed certs now produce hard errors without any option to override!!! It’s so damn messed up! If you need a test, try https://www.sf.net for a mismatched one. Please try it for yourself and see what I mean.

Hi Nicholas,
I can definitely sympathize with your frustrations. It was being as pissed off as you that motivated me to write RMD in the first place.
You may want to grab beta 5 of FF and run through your scenario again. While you get an in-page security error, there is a link to add a security exception which allows you to override it (and remember the override). Admittedly it is three clicks, rather than two with RMD but it’s not a *terrible* compromise, IMHO.

Hi Andrew.
Just upgraded to Thunderbird 2.0.0.14, and it seems to be forgetting domains again. Not a big deal, just thought you might like to know.
Running Thunderbird for Linux on PCLinuxOS. All other add-ons seem to be working OK.

Hi Jim,
Could you try the compreg.dat removal trick to see if that clears it up?
I don’t think I’ve tried RMD with TB 2.0.0.14. I’ll give it a shot when I get a chance.
Cheers,
A.

I wanted to thank you so much for this AddOn. I’ve been using it for some time now.
Finally, Firefox3 has this functionality built-in. It’s a bit clunky but it works as-expected.

Hi Andrew,
First of all, thank you for the add-on, is very useful, even taking into account that is not allowing me to do the main thing I want to do with it ;)
I am trying to use RMD to avoid having to accept a certificate each time I run a test using Selenium. I tried it by installing both the add-on using a normal Firefox instance and using one opened by Selenium, but it simply doesn’t work. You can have the add-on installed, but it dissapears from the list when you open an instance using Selenium.
I would really appreciate any suggestion that you could give me about how to use RMD with Selenium.
Kind regards,
Gerardo

Hi Gerardo,
I’ve never used RMD with Selenium but have noticed that RMD is a popular extension with that crowd ;-) If you’re using the RC mode perhaps this will help?

Hi again Andrew,
Thanks for your answer. Just to point out that, after having added RMD to your new custom Firefox profile, and before trying to use it with Selenium, you need to open Firefox using that new profile, open the page you want to test, and accept the certificates, telling to RMD that you want it to remember them (if you try to do it whilst using Selenium, the certificates won’t be remembered). Once this has been done, you can run your Selenium tests smoothly thank to RMD !!! ;)
Thanks a lot,
Gerardo
