Tampermonkey

Tampermonkey was first created in May 2010 by Jan Biniok. It first emerged as a Greasemonkey userscript that was wrapped to support Google Chrome. Eventually the code was re-used and published as a standalone extension for Chrome which had more features than Chrome's native script support.{{cite web |title=Tampermonkey • Contribute |url=https://www.tampermonkey.net/contrib.php?ext=dhdg&show=dhdg |website=www.tampermonkey.net |accessdate=7 November 2019}} In 2011, Tampermonkey was ported to Android, enabling users to use userscripts on Android's internal browser.{{cite web |last1=Linder |first1=Brad |title=TamperMonkey brings GreaseMonkey user scripts to Android |url=https://mobiputing.com/2011/06/tampermonkey-brings-greasemonkey-user-scripts-to-android/ |website=mobiputing |accessdate=7 November 2019 |date=4 June 2011}} In Jan 2013, after the publication of version 2.9, Jan Biniok decided to change Tampermonkey from open source (GPLv3) to closed source (proprietary). By 2019, Tampermonkey had over 10 million users. By 2022 Tampermonkey was one of 33 extensions on the Chrome Web Store to have at least 10 million users.{{cite web |title= List of Chrome extensions with 10M+ users |url=https://chrome-stats.com/user-counts/user-10000000 |website=chrome-stats.com |accessdate=28 December 2022 }}

In January 2019, Biniok wrote in a Google Groups post that the new Chrome manifest V3 would break the extension. The new manifest would ban remotely accessed code which Tampermonkey is dependent on.{{cite news |last1=Lawrence |first1=Abrams |title=TamperMonkey May Be the Next Victim of Google's Chrome Manifest V3 Changes |url=https://www.bleepingcomputer.com/news/google/tampermonkey-may-be-the-next-victim-of-googles-chrome-manifest-v3-changes/ |website=BleepingComputer |accessdate=8 November 2019 |language=en-us |date=28 January 2019}} The userscripts use code that is created by developers not at Google, rather they are created by third-party developers at places like Userscripts.org and Greasyfork. This code is inserted after the extension is installed, however the manifest requires the code to be present at installation.{{cite web |last1=Bradshaw |first1=Kyle |title=Chrome's Manifest V3 proposal would break Tampermonkey |url=https://9to5google.com/2019/01/29/chrome-manifest-v3-tampermonkey/ |website=9to5Google |accessdate=8 November 2019 |date=29 January 2019}}

On January 6, 2019, Opera banned the Tampermonkey extension from being installed through the Chrome Web Store, claiming it had been identified as malicious.{{cite web |author1=Venkat |title=Opera blacklists Tampermonkey extension, says extension is Malicious [Updated] |url=https://techdows.com/2019/01/opera-blacklists-tampermonkey-chrome-extension-says-it-as-malicious.html |website=Techdows |accessdate=8 November 2019 |date=5 January 2019 |archive-date=8 November 2019 |archive-url=https://web.archive.org/web/20191108004430/https://techdows.com/2019/01/opera-blacklists-tampermonkey-chrome-extension-says-it-as-malicious.html |url-status=dead }} Later, Bleeping Computer was able to determine that a piece of adware called Gom Player would install the Chrome Web Store version of Tampermonkey and likely utilize the extension to facilitate the injection of ads or other malicious behavior. The site stated, "This does not mean that Tampermonkey is malicious, but rather that a malicious program is utilizing a legitimate program for bad behavior," going on to call Opera's blacklisting the extension for this reason a "strange decision".{{cite web |last1=Lawrence |first1=Abrams |title=Opera Blacklists Tampermonkey Extension Being Installed by Malware |url=https://www.bleepingcomputer.com/news/software/opera-blacklists-tampermonkey-extension-being-installed-by-malware/ |website=BleepingComputer |accessdate=8 November 2019 |language=en-us |date=6 January 2019}}
