• (2023-11-06) Sergio N. Bonacina: una mentira ya lo desinstalo
• (2023-10-18) Jo me: Works awesomely
• (2023-10-16) Mari Leigh: I love it. It can't always find free versions of research papers/journals, which is annoying, but most of the time for me it can. As much as I'd like to support the researchers and buy their research journals/papers, I cannot pay upwards of $40USD for a single article. I definitely suggest if you are a student who needs to use credible sources for research papers, I highly recommend this app. Like I said, it can't always find free versions, but it's worth a try :)
• (2023-10-09) Natanael Leitão: Works only on articles that are already free.
• (2023-09-20) Adrian Augustus: **Note its for scientific journals not mainsteam media like Wall Street Journal.** The extension name could perhaps be a little less generic. As for use in journals I typically access - this works, rarely. To concur with some of the feedback here - only occasionally does it procide access to a pdf, sometimes it fails when a pdf is available almost at the top of a google search, sometimes a bit more digging is required. Nice idea though.
• (2023-09-15) Mysan trope: Not working.
• (2023-08-07) Andrzej Rutkowski: It's kind of useful, but sometimes it fails to detect the available full versions of articles. I mainly spend my time on Pubmed and sometimes there's a paper there with a clear link to the full free version of the article on Pubmed central, but Unpaywall still says that there is no free full version of this paper available. When the Unpaywall padlock icon is open and green - yes it is useful to be able to just click it and go directly to the free full version. But when the padlock is grey and locked, I still do my own search for a free version (often successfully), but I thought that this searching on my own was what this extension was supposed to save me time on.
• (2023-06-02) Atharva Kulkarni: Best
• (2023-05-23) Fabien cmoi: faut s'abonner ou pas ? en tout cas ca marche pas
• (2023-05-03) Leniero: Funktioniert bei keiner der getesten Seiten
• (2023-01-11) Lee B: Doesn't work.
• (2023-01-07) David Linder: Only tried it on one article, worked first time, gave me the full article without paying. So super happy, thanks.
• (2022-11-18) Alkaris: This extension does NOTHING on sites like New York Times, or Washington Post that all use paywalls.
• (2022-11-01) ZeyTac: not working.
• (2022-10-23) Alex: Won't work on vast majority of articles unless they're already open-access, which defeats the purpose of this extension. Basically does little more than being a PDF downloader.
• (2022-09-28) MeeM: About as useless as a glove with 4 fingers
• (2022-09-22) Ektor: No sirve en un articulo de la Universidad de Cambridge desinstalando
• (2022-08-31) Oliver Jay Aaby: Ikke hvad jeg forventede - men fint koncept.
• (2022-08-25) Nexsus: It just sends you to pdfs
• (2022-08-15) Ahmed Kamal Hasin: It doesn't work for all paywalled articles. If you're lucky you'll get some of them. Still worth a try if you're a student and looking for secondary sources for your assignment or paper.
• (2022-07-19) TRAVIS I.: Does not work on news articles. Useless. Don't care for research papers which are ALREADY FREE.
• (2022-06-22) Joachim Mirwald: bei mehreren Seiten getestet und kein ging
• (2022-06-09) Galaxyz Fold2: looks like no longer work in 2022
• (2022-03-23) 张huayu: 现在2022年了，但2020年的文章还是看不成，可能是由于学科问题吗，感觉sci-hub会好些
• (2022-03-21) Evelyn Taronas: i did research and it doesn't work at all, it have paywall tho but i did not see the lock icon the side of my desktop
• (2022-02-18) Nash 52: Ja richtig
• (2022-01-15) Zuzana Kocsisova: Works so well! Super easy to use.
• (2022-01-07) Sky Jaap: Makes it easy to find the pdf version of an artikle without clicking though several links.
• (2021-11-23) Mohamed Sahl: I only downloaded hoping that it would crack past "theathletic" dot com articles. but seems it's hard for you :(
• (2021-11-16) Yan Ortiz Gutierrez: no funciona en scribd
• (2021-10-01) alessandro vergoni: SEXOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
• (2021-09-22) Matias Solorzano: He probado la extensión en varios sitios y esta solo funciona en páginas específicas, inusualmente recurrida
• (2021-09-02) e a: 很好用
• (2021-08-21) Floyd Romanoff: Downloaded to find critical article for a paper. Instantly found it. So easy to use, just perfect.
• (2021-08-04) Emmanuel Grant: It Didn't work! . I tried it on different sites and it didn't work on any.
• (2021-07-28) Alejandro Toloza: No funciona con Scribd, al parecer con muy pocos sitios funciona
• (2021-07-21) NIVΚΓΔ: Worked once....for a free article out of 20 articles I tried, redundant.
• (2021-05-04) Paul S.: This app did not help me get pass paywalls at all. This app gives me one of two things, it either redirect me to a pdf file that was useless or it did not give me an option to bypass a paywall at all.
• (2021-04-27) Wesley: Doesn't work on New York Times, so it's pointless
• (2021-04-20) Liv S: Not bad. Just recently installed and have noticed that there were a few papers that had the green leaf on the side. I'll continue using it and see how it goes! Thanks :)
• (2021-03-24) Marijus Lapinskas: does not work with vz.lt
• (2021-03-23) hmoh-: I just wanted to know if it slows down performance of the device you get it on in any way?
• (2021-02-23) Alex Montero: First paywall breaker that actually worked for me, thanks!
• (2021-01-25) Julian Vargas: No funciono con The Economist
• (2021-01-10) Jay Guerrier: An incredible asset this past semester for me. I was able to access way more research than I would have been on my own and it definitely reflected in my grades!
• (2020-12-10) Anass: Amazing
• (2020-11-27) Matthew Brooks: It actually works... So far it's 1 for 1. Even if it doesn't work for any other scholarly articles it was still worth the download. Fantastic!
• (2020-10-29) Кирилл Фролов: I would like it to open unpaywalled article ajacent to the current tab. Not after the rightmost tab.
• (2020-10-11) Sergey Nabrusko: super!
• (2020-08-19) Kaitlyn Krenik: I downloaded to try to unlock Wall Street Journal. Doesn't work. Also doesn't work on any psychology articles I looked for.

  Does this work on sage pub?
• (2021-03-20, v:3.94) Alex W.: Read and change data on all websites
  This is overreaching for an extension that should need nothing more than the URL. I don't need a special button injected into every web page. Just let me click the extension button when I want to check for an open access article.
• (2020-11-28, v:3.92) D D: its not working on https://simplywall.st/

• (2018-12-04, v:Unpaywall 3.87) reader
  Compare the latest Top 500 list with the Top 500 Green List of HPC systems. Discuss a few top winners and losers in terms of energy efficiency in power and cooling costs. Reveal the green energy winners’ stories and report their special design features, packaging, cooling, and management policies that make them the winners. How different are the ranking orders in the two lists? Discuss their causes and implications based on publicly reported data
• (2018-09-02, v:Unpaywall 3.77) Charles Williams: Read and change data
  Why does it need to read and change data on websites visited? What exactly does this mean and does this apply to every website visited or only to the websites that contain the articles and papers being accessed? This is a question that has been asked many times before but has yet to be answered. Please answer as clearly/detailed as possible. Thanks.
• (2018-03-06, v:Unpaywall 3.76) Can you kick off this
  Can you block me from using this it has been interfering with other things
• (2017-09-15, v:Unpaywall 3.0) NPAVisuals Nicholas Pearson Associates: No longer working
  No longer pops up on screen when viewing a journal article listing. Seems others are seeing the same thing. Shame, I liked this extension.

  Acer Chromebook 11 running Chrome OS ver. 60.0.3112.101. Installed fine, but clicking on the little tab takes me to an error page.
• (2017-08-03, v:Unpaywall 2.4) David Hopgood: Unpaywall doesn't work in Chrome
  I tried installing Unpaywall in Chrome - nothing happened. Please advise. David Hopgood
• (2017-07-03, v:Unpaywall 2.3) Dispense with the huge button
  Having a huge big green thing on the side of the screen when I read articles online like at PubMed is a huge distraction. You should give the option to only light up the mini icon on the toolbar and get rid of it on screen.
