どうもアドオン「Configuration Mania」の設定のせいだったことが判明し、設定を「標準に戻す」事で、webclipperの設定が保存出来るようになりました。google検索やYoutube,amazonでポップアップがでて鬱陶しい方は、Configuration Maniaが入っていないか見てみて下さい。

Every single release I had to reinstall presious version 6.9.3 to make it work....What are you doing, trying to kill your business?

I pay $50US every year to Evernote. Can't you guys figure out how to make this thing work, not only with the browser, but with other extensions/add-ons? Seriously, EWC has been broken for months on Firefox! Clearly still works, and that was discontinued! Before FF 54.0 update, the only way I could make EWC work was to delete EWC. change some FF privacy settings, log into EN Web, and then re-install EWC...., to get the clipper-sso cookie, but that only works for that session! if i close my browser, it logs me out of EWC, and we start all over again! Now, After 54.0 update, EWC wont even let me log in.... The login window appears, there is data transfer, and then it just closes!

SO MUCH FAIL!!!!!!!!

ほかの方のレビューにもありますが，最新版のFirefox 54 で動きません．Firefox Nightlyも利用してるのですが，そちらも動きません．

修正するつもりがないのか，かなり放置されている感じがします．

I used to use this with Firefox all the time and get the 3 options without issue. Now, the button doesn't even show up on the browser.

The most loved add on

I've installed it... and nothing happened - not a sign of it in my Firefox (53.03 64 bit)

Edit 22 June 2017: seems to be working after latest update. Thanks, devs.

Won't load the sign-in page. This has been out of action for months now. I installed an older version which worked for a while, but now that's not working either. Very disappointing.

Edit: I followed advice from other users to get it working:
1. go to Preferences > Privacy > History/Cookies > Exceptions and add "https://www.evernote.com/"
2. visit https://www.evernote.com/Login.action?targetUrl=%2FHome.action to create a cookie
3. reinstall the add on.

I´m a Premium user and can´t use all the features properly. I can only suppose that there´s a problem between Evernote and Mozilla, because I´m currently beeing forced to use other navigator.

Fix this Evernote. This is part of the product that we are paying you for. The addon has been broken for more than 6 months.

after login web clipper works in firefox.
BUT each time I open a PDF document in firefox there is a really annoying web clipper popup. Since the popup cannot be stopped I deinstalled web clipper.

my firefox version is 43.0

JUST opened an Evernote paid account. Their cute little elephant symbol for a web clipper seemed to point to a useful tool, why not add on?
Not working?
Let me see the user reveiws. Oh, change my options to accept their cookie?
No problem. Except...BIG problem. There's no longer an "Options" under my "Tools" instead there's some slick crap. Oh, maybe useful. But I didn't say "change all that without even giving me the option to say no"
NOW, I have to uninstall everything, and start from there. As His Orangeness would say "Boo!"

6.2之後的版本，全部都無法安裝至火狐瀏覽器。

The most benefit of using this tool is you have to install Evernote for Windows or for Mac and create an Evernote account and start syn it with this add-on. When you take screen shot with this Web Clipper it will automatically syn to the Windows or Mac app.

It works well in chrome but in firefox it just doesn't even work. It shows a window to sign in the first time but after that, every time I press the elephant it just doesn't show the clipping options and it doesn't do the clipping work as it's supposed to.

Give it a shot yourself. It works for me on Windows at least.

Dear developers of this plugin, please fix the install file. Not fixing this for months will not motivate people to upgrade to a paid Evernote account.
