This doesn't work with Firefox

It is not work

Awesome

I was experiencing exactly the same issue as everyone else with the authentication problem. I resolved this by adding an 'Exception' rule for Cookies within Firefox. Open up the FireFox Options screen, click on 'Privacy' in the left hand menu, click on the 'Exceptions' button that is on this page, add the address of the website - https://evernote.com - give it an 'allow' status, click 'Save Changes'. Once I had done this, closed and restarted the Firefox browser. Clicked on the Evernote icon in the top toolbar, entered my Evernote credentials, and it worked straight away. The red dot is no longer there and clipping works brilliantly!

Icon has a red dot. After login with credentials of evernote this function is not usable anymore. Short popup screen which disappears immediately. Sad situation!

doesn't work for china edition(印象笔记)

add-in doesnt work (in firefox); how should I clip into evernote?

& evernote printer-driver does not exist although requested for years by thousands of users: really bad management-decision!

Nach Klick auf das Symbol öffnet sich nur kurz ein Popup und verschwindet wieder

Can't login

... since weeks, it pops up "advises" randomly on pages and systematically on pdf, despite the opting out (hidden in the prefrences).
Without any move from evernote the only posibility is to uninstall the trespasser.

I have tried to install Evernote web clipper randomly since 3 month. It always fails.

'The add-on downloaded from this site could not be installed because it appears to be corrupt.'

It works fine for me, love it. Can't wait to get more templates for notes, integration with google sheet, cloud/offline DB query/report!?

Nothing works.

Now it doesn't even work. Will not access my Evernote folders, and just keeps trying until I end the operation. Also, what's with all the new, annoying, and impossible to disable "feature" pop-ups?! Stop bothering me. I know how it is supposed to work. I actually pay for the product, too. A pity OneNote sucks worse.

我用的是国际版火狐，然后插件就自动登录国际服evernote，我无法登录国服印象笔记，自作聪明！垃圾！

I use english firefox not CN firefox, and I want to login as CN evernote server, which means yinxiang.com . But I didn't find any method to swich to CN server. rubbish！！！

In my opinion the latest version of this add-on works great in FF 51/Win10 configuration. You have to check "Remember me for 30 days" ticker AND add set FF to accept and keep cookies from https://evernote.com. Otherwise you will have to log in each time you start FF. With these options set, things works just fine. Clipping, saving PDFs, saving entire Gmail conversation - options I use the most. After successful clipping the note is immediately visible in the web interface and on my phone (after a sync). I give 4* because of the complications with staying logged in.

I was a little bit concerned reading all the negative reviews on here, but I just installed it and everything seems to be working smoothly and in the way I'm used to from Chrome. (FF 51.0.1 and OS 10.12.3)
