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,
A.

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.
andrew says:

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

Hey there,
I’d like to use this wonderful extensiuon, but on Debian Etch (64Bit Version) that thingie doesn’t run.
Although ‘Linux_x86_64-gcc3′ is in the install.rdf:
Linux_x86_64-gcc3
Anyways – it says that your plug-in is not compatible with this build of IceDove (Thunderbirds Debian-name).
Greetings

Hi Andrew -
Just wanted to say thanks for your extension, and I really sympathize with Nicholas above — the new exceptions handling in FF3 keeps FORGETTING my exceptions (despite my selecting ‘remember permanently’). RMD never did that – I wish I had it back.

Hi there
Gr8 plugin. I had been using it on RH5 for a while without problems. However after i moved my TB (2.0.0.17) profile folder to USB drive RMD became useless. It keeps asking the same sertificates and keeps adding them. I have a huge list of sertificate domains however RMD dont remember them and keeps asking.
Any solutions?

It doesn’t seem to remember the domains in Seamonkey (1.1.14 on Linux, downloaded installer)

Hello,
Thanks for this good and useful plug-in. Do you plan to make it FreeBSD compatible (FreeBSD_x86-gcc3)?
Cheers,

SeaMonkey Problems
I installed RMD as I have a site I must access via IP rather than URL that is mismatched with its security certificate. RMD changed the error message I get when I go to the site, and what I read is in a language that is not English. I check the spot that in English would say “Don’t warn me again…” and it goes into RMD’s “Asetukset” page I can access in Seamonkey. It does not work; every time I start Seamonkey I get the error message, check it, and the data is added to the “Asetukset” page as another duplicate entry.
I uninstalled RMD and reinstalled it several times (in the application folder) with the same results.
I uninstalled RMD again and then tried to install it in the profile folder instead of the application folder, in case that might work. That resulted in an error “The installation of RMD failed. Chrome registration failed”.
I uninstalled RMD again. Now I’m not given the opportunity to install in the application folder; I get the Chrome registration failed message instead of the window that allowed me to select the application folder.
How do I install this add-on, how do I install it in English, and how do I make it work?

Hi, My experience with RMD on SeaMonkey 1.1.9 On Win2K
is exactly like Jay O’Brien’s. It comes up in a foreign
language, and fails to work, adding a new record each time.
(Uninstalling it for a global installation was a bit tricky,
involving editing various files in the Chrome directory
to get rid of any references to it.)

Hi, I also had problems with the language. My Thunderbird is Dutch, but RMD came up in Polish. I found that chrome.manifest had mixed these, and after changing that I could understand the text a lot better. Other than that, it was already working great. Thanks!

Seamonkey 1.1.16 on XPSP3: I was glad that someone provided a solution to this mismatched domains problem, but RMD doesn’t work here: it installs in Finnish, and checking the “don’t remind me again” checkbox adds the correct address couple to the mismatched domains list, but this doesn’t supress future mismatched domains warnings for that couple.

Thank you so much! It still works in the latest version of Thunderbird 2.
This addon is FANTASTIC, it saves me from seeing that pesky dialog every time I start Thunderbird to check mail. THANKS THANKS THANKS! :-D

Hi Andrew,
i recently changed to TB3 and i have to say: Your addon is still needed there!
Not for the mail accounts but for RSS feeds. If you have an RSS feed that links to a SSL site with a certificate dialog (outdated or wrong certificate) you still have no possibility to dismiss the dialog permanently. As you know this is very, very, very annoying.
Is there any chance that you port the addon to TB3?
Rene
Rick says:

I also need the addon in TB3. I use the lightning plug-in and the server holding the iCal files uses an invalid domain. TB3 does not give me the option to dismiss the error, not even for the current session.
