The new version is working well for me with multiple gmail accounts and one yahoo. I went back to the the previous one just to backup my accounts and then successfully restored them on the new one. At first it seamed like it was not working but after a Firefox restart everything is working just like before. This is still the best email notification extension out there. We should all give the developer time to adjust it and fix what its not working properly yet for everyone.

If you want to stick to 3.5.23,

1. In Firefox's Add-ons Manager -> X-notifier -> More -> Set 'Automatic Update' to 'Off'

2. Install 3.5.23 from here https://addons.mozilla.org/en-US/firefox/addon/xnotifier/versions/

This version will stop working in the future according to Firefox team's plan.

IT WORKS :)

Multiple login issue IS addressed in 4.0.2 and it works fine. If you updated from 3.x, then reinstall the old version from the version history, export the settings before updating, and then re-import them after updating to 4.0.2.

In using the extension, I didn't really use it to do anything fancy - so everything seems to work the way it did. Only difference I can see is that it takes one more click to open up all the mail accounts at once; but I used to do that by accident all the time, so I don't know if this is something that I am too unhappy about.

Kudos to the developer for taking the time and effort to port it to the new standard. Many developers in the past have abandoned development on their extensions when something like this happened, and I am just grateful that this one is going to survive another generation of firefox.

That said, I DO wish more of a warning was given so that people did not think all their mail account setting went up in smoke, but I don't know what the developer could have done.

I had problem with last version, just reverted one before version 4, its 3.5 something and everything is working like a charm! Thank you for this add on developer. And this also brings back the deleted accounts....

I updated this new version in mozilla and after clear history this addon is asking me to enter the password again, but before it fine and never asked me to enter password. Another issue is we have to use only one Yahoo id otherwise yahoo ask us to change password again, i think that is because of the yahoo security risk. so please can you fix these issue.

I installed v4.0.2 and it's working fine now with me, Only adding 2 Yahoo accounts not working fine, sometimes Yahoo ask me to change my password and no option to open the Email without it but if i wait for sometime i can open it normally, i think it's not the addon problem, Thanks for your work
BTW i'm using FT DeepDark theme and the addon menu looks black like the theme is there a way you can change the colors or add option so we can change colors?

Thanks Again

I am saddened to see so many raging reviews and all my sympathy goes to the poor developer.
Please folks, take a little time to understand the reasons behind the change: mozilla deprecated and will perhaps remove the internal mechanism on which the dear old x-notifier relied upon. The developer has to deal with new APIs which are not necesseraly as powerful and permissive... and he's doing this mainly for passion (99% of you, me included, haven't donated a cent for this software).
So why bash him?? Just revert to the older version (no data lost) and disable automatic updates, it's as simple as that!

And look these kids keep posting 'bad update' one stars reviews.
Can you ever try to READ?
THIS IS NOT DEVELOPER FAULT THAT YOU LOST YOUR LOGINS/PASSWORDS.
Blame Mozilla because they force developers to use WebExtension API in newest versions of Firefox.
And blame yourself because you ignored warning from developer.

Hi,

This is the first time I post a review,I can't imagine a day without X-noitifier, you do a great work,.... but this new update isn't that good, I prefer expand mail list with right click and the old options panel was better, Thanks for this great & indispensable extension

I really loathe the new update which makes all the logins disappear and only the main one is kept, plus there's no right-click like before.

The solution? Download the 3.5.23 version and use that. Disable the option to download updates so the newest version won't be installed.

Well there is a solution !!!
DO NOT UPGRADE FIREFOX TO v.50 !!!
If you already done so then uninstall and install v45, v47 or v49 (max). you can download it from http://filehippo.com/

Après le petit bug de la version 4.0.1, la nouvelle version 4.0.2 fonctionne parfaitement avec Firefox 5.0
Cette extension est très bien. Je suis fan depuis des années
Merci aux développeurs

All data is back when install old version.
Here is the old version on x-notifier:

Hi, I've been using this plugin for several years now and badly need to work it out on latest version of firefox please?

PLEASE PLEASE make it work with Firefox 49.0.. I don't want to use other plugin.

This great add-on has stopped working with the latest updates of Firefox. Is dead.

We really need this.

Dear best email notifier...

why you doesnt work 49.0??

Лучших нету, но перестал обновлять, придется удалять (

никто не решил пробл с рамблером?

The best email notifier out there A+++
Please update as it isn`t compatible with Firefox 49 ☹.
Thanks

I have many acounts of yahoo, it just active one

X-Notifier (latest version is 3.5.23) works great with Firefox 49.x and below.
The API programming interface is changing with Firefox 50.x and so X-Notifier cannot continue with the same features.
The newer version, X-Notifier Neo has been recommended for Firefox 50.x and above.

this is a reliable email notifier. i hope it gets updated for future FF builds.

It seems it doesn't support e10s but since e10s is disabled on my profile, I couldn't say if it still properly works despite that.

I know mozilla changes too frequently and it's pain in the as* for dev to maintain their add-on. I empathize with you. I hope it will be compliant with future firefox release. I love it.

Do you plan to update it to make it e10s compliant?
