Image from store ModHeader
Description from store The most popular Chrome extension to modify headers ** What can ModHeader do?** - Add, modify, and remove request and response headers - Use ModHeader to set X-Forwarded-For, Authorization, Access-Control-Allow-Origin, etc. - Modify cookies in request / response header - Redirect URL with another - Enable header modification by URLs - Advanced filtering by tab, tab group, or window ** Where is tab lock ** - Tab lock has been redesigned as Tab Filter and can be found in the + button. It is still available for free users. ** Why ModHeader ** - ModHeader is fast, efficient, and light-weight. You can quickly enable/disable header modification with just 1-2 clicks. - ModHeader provides you with many convenient features that will help you increase your development velocity with the least amount of frictions. Check out the big list the features below! - ModHeader is free to use, with a paid option to unlock even more features. - ModHeader works on Chrome, Firefox, Edge, and Opera. - ModHeader is used by over 550,000+ users on Chrome Web Store! ** ModHeader features ** - Add comments to header - One-click "undo" if you made a mistake - Support having multiple profiles with quick switching between profiles - Export and import profile - Easily share your profiles with others - Customize autocomplete names and values - Dark mode support - Sorting headers and name, value, or comments - Append value to existing request or response header - Customizable profile badge - Clone profile - Cloud backup ...and more!!! ** What is new in 4.0.17 ** - Allow ModHeader to read from managed storage (for enterprise) - Fix CSS not loading correctly ** What is new in 4.0.16 ** - Add regex cookie matching and ability to retain cookie value while modifying its attributes ** What is new in 4.0.15 ** - Add support for Time filter ** What is new in 4.0.14 ** - Dependency upgrades and some minor bug fixes ** What is new in 4.0.12 ** - Support auto-sync profile import: https://docs.modheader.com/profiles/auto-sync-profile - Remove support for dynamic value as Firefox addon policy and Manifest V3 both disallow it. If you need this feature, please email [email protected] and we will try to figure out how to support your use-case. ** What is new in 4.0.10 ** - Profile search support - Auto expand left panel on tab view ** What is new in 4.0.9 ** - Minor UI updates ** What is new in 4.0.8 ** - Support reordering profile, headers, and filters. ** What is new in 4.0.7 ** - Fix profile switching not working ** What is new in 4.0.6 ** - Add link to create login URL to quickly login to additional browser / browser profile. ** What is new in 4.0.4 ** - Fix crash due to tabs not found - Fix ModHeader not working on older browser ** What is new in 4.0.0 ** - Support enhanced cookie modification - Replace tab lock with tab filter, along with tab group and window filter - Support autocomplete customization - Dark mode support - Keyboard commands mapping - Give users more controls over share profile URLs - Paid subscription required for some of the newly introduced features. Most existing features should continue to work for free users. ** Older changelogs ** https://docs.modheader.com/whats-new/version-4.x ** Permissions ** ModHeader currently requires 6 permissions: 1, "webRequest" 2, "webRequestBlocking" 3, "<all_urls>" 4, "storage" 5, "contextMenus" 6, "alarm" "webRequest" and "webRequestBlocking" are required in order for request headers modification to work. Because ModHeader doesn't know ahead of time which website the modification should apply to, it needs to request permissions for all URLs (3). "storage" permission is needed to save settings to the cloud. "contextMenus" is used to enable quick pause/unpause by right-clicking on the icon. "alarm" is used to periodically auto-sync profiles (if auto-sync is setup). ** Source code ** https://github.com/modheader/modheader ** User guide ** https://docs.modheader.com/ ** Privacy Policy ** https://modheader.com/privacy ** Automation ** For Selenium WebDriver users, please try: https://github.com/modheader/modheader_selenium To find ModHeader on other browsers, visit modheader.com

  • (2022-07-28) Derek Lam: cannot add profile
  • (2022-07-25) Robin: Works fine when you're trying to modify request headers, but at the time of writing this, the extension is unable to edit response headers. Is there an explanation for this behaviour?
  • (2022-07-21) Mohamed Ettaki TALBI: dark mode bugs the extension, I loast all my headers configuration. And in the lastest release it's limited to 3 profiles instead of 5
  • (2022-07-15) Pei Li: 太好用了,前端开发者的福音
  • (2022-06-16) Tian Ling: 好用,方便快捷, 没有理解成本
  • (2022-06-06) qi molly: 打开新页面的时候必须手动去刷新页面?有什么方法可以解决吗
  • (2022-05-31) Nick Swenson: Was useful, now it costs to have more than 3 profiles. Removing features to lock them behind a paywall, sheesh. Also, it just deleted all my profiles for whatever reason.
  • (2022-05-19) Miles Sorce: Very broken. Worked flawlessly since I started using it in August 2021. But since using the new version, it is really painful to use. Let's say you have two profiles with separate headers and URL filters. When I disable all headers and filters on Profile 2, then the Profile 1 headers are added. But if any Profile 2 headers or filters are enabled, even if Profile 2 is disabled, the Profile 1 headers are not added. In other words, the enabling and disabling of profiles does not do anything.
  • (2022-05-18) Jayant Jain: Used to be perfect for my needs. Now it simply doesn't work - the extra headers are never sent. I checked tab filters, URL filters, everything.
  • (2022-05-17) Bart Kemps: Pretty useful, I've installed in a dozen browser profiles. I'd gladly donate $50 to keep this thing going. I won't pay for a $2 subscription because re-activating it for new browsers/browser profiles is simply not feasable. Two stars because basic functionality is still OK and free. But I need to mod cookies so I'm switching to a different tool.
  • (2022-05-12) Serge: Хорошее дополнение)) UPD: Сломали хорошее дополнение. Очень печально.
  • (2022-05-11) Furkan Kaan: son güncelleme ile bir çok özelik için ücret istiyor ve sekmeye özel kilitleme özeliği kaldırılmış!!!
  • (2022-05-11) Daniel Hodgkins: Incredible Application! Very responsive creators and does exactly what I need! (even if I'm a little blind at times 😆) Highly recommend the documentation as it's very informative! --- Previous Review (based off incorrect information) This extension is exactly what I needed! ... Until they removed the only feature I actually needed it for, locking the requests to a specific tab. Since the latest update I cannot find the functionality to lock the header rewriting to a specific tab, allowing me to use my emails and still do development testing at the same time. A shame really 😬
  • (2022-05-11) Paul Shambrook: Removing free tools and making them a paid for function, I have been using this tool for years disappointed that they have now removed the Tab lock feature from the free version , so will need to look elsewhere for this feature.
  • (2022-05-11) Hanyang Gu: totally broken, it's become blank page after the latest release...
  • (2022-05-10) Jeremy Simkins: Broken. I just installed this and the view has no style applied to it. It's completely unusable. It's like it's missing the stylesheet and it's such a mess, it's not possible to use. This is unfortunate. I also didn't realize this is a paid for extension... seems a bit much ($4/month) given the simplicity of this extension so I will look for alternatives or build my own.
  • (2022-05-05) Milo De Nadai: I don't have anything to say about the extension's functionality but it uses up a lot of my CPU even when it's not doing anything so I suspect it has some kind of malware embedded in it.
  • (2022-04-22) David Johnson: Love this extension! It is so helpful for development.
  • (2022-04-22) kai he: 好用!!!!!
  • (2022-04-21) Daria Sysoletina: This extension makes my life so much more comfortable! I use it every day in my work routine. Only one thing I would recommend you to improve - it would be great to have comments to request headers in the main window, just not to open expand window every time for every single header
  • (2022-04-19) fu qin: 不错,很好用
  • (2022-04-01) Philip Rhoades P: I want to change URLs like: https://www.youtube.com/watch?v=Od49AfIS2-U&ab_channel=DUST to: https://www.youtube.com/watch_popup?v=Od49AfIS2-U&ab_channel=DUST ie Regex for all URLs: https://www.youtube.com/watch?\(.*\) to: https://www.youtube.com/watch_popup?\1 Can this be done somehow? - I will raise the rating to five stars if you can do it! Thanks, Phil.
  • (2022-04-01) 陆海建: 很好用
  • (2022-03-30) Shaedo: It's really simple. But I have absolutely no idea how to use it. There is barely any indication of what to do.
  • (2022-03-08) Christian Traub: In chrome 98.0.4758.102 (Official Build) (64-bit), switching a profile does not update the form or display the active element. I have to exit the popup every time. Is this a side effect of another plugin?
  • (2022-03-07) Bhone M Min: SHEESH. So good for devs.
  • (2022-03-03) 徐晓: 辣鸡
  • (2022-02-25) 高冬雪: 不知道为啥。总是下载失败
  • (2022-01-17) Clément Farkas: L'application se permet d'installer un malware qui ouvre une iframe sur les moteurs de recherche vers servisepagefind.com . A désinstaller d'urgence !!!
  • (2021-11-27) Giftina Chen: 好用, 以前曾经有过的后台代理也已经删掉了
  • (2021-11-19) KingLiang Gu: can you support http2 to modify http2 headers?
  • (2021-10-20) Artem Rikoski: THE BEST
  • (2021-10-08) 包李文: pretty good
  • (2021-09-25) Ahmed Magdy: Excellent extension, for redirecting url to another one
  • (2021-08-24) Kayo de Bakker: Great tool for debugging but it would have been great if there was an option where you can disable this for certain sites or better yet only enable it for certain sites. I often come across the problem that some random site doesn't work because I still have this tool on while I was debugging on a local instance.
  • (2021-08-19) 楊凱霖: very useful when facing CORS or CSP issues.
  • (2021-07-13) Piotr Kruczkowski: Wtyczka co chwilę nie działa, po kliknięciu wyświetla się białe okno, a ustawione nagłówki usuwają się. Myślę, że to przez to, że wersja jest aktualizowana, ale dlaczego kilkanaście razy w ciągu godziny?
  • (2021-06-26) Şahin Kasap: Doesnt work. White popup when clicked. Background tab gives the errors on console: Unchecked runtime.lastError: Tabs cannot be edited right now (user may be dragging a tab). background.bundle.js:1 Uncaught (in promise) TypeError: Cannot read property 'id' of undefined at onTabUpdated (background.bundle.js:1)
  • (2021-06-25) Eric P: Great for dev testing!
  • (2021-06-17) Brian Burns: Easy to use, thank you :) But make sure if you use an Accept header that your service can actually supply that format - I was hitting an MTConnect Agent to get JSON output but didn't realize they didn't support JSON until v1.5, so kept getting back XML!
  • (2021-06-17) Eric Maas: Great tool for down and dirty headers.
  • (2021-06-16) Lorenzo Martini: potreste spiegare a cosa serve ?
  • (2021-05-27) Анатолий Иваненко: Отличное расширение))
  • (2021-05-25) Ilya Trushchenko: Could not make it to apply different headers for different tabs.. UI is not intuitive
  • (2021-05-18) 黎国贤: 请问一下,该插件的header的key,在实际插入请求header的时候会转换成小写,这个是什么原理呢?如果需要保留大写,需要怎么操作呢。
  • (2021-04-08) Deniss Dmitrijevs: Very simple in use.
  • (2021-04-07) ZONG ZU: chrome最好用的修改请求头的插件

    Hi. This extension used to work. But, in trying to add an arbitrary Referer header to a request, I am finding it is not being attached. I can verify this by added a Referer header, and then going to any website, and looking in the javascript console at the "document.referrer" value. It is consistently empty even though I am attaching a header to the request. In curl, I can do this using the -H flag to add an arbtirary header.

    I am once again getting the following error in the latest version of Google Chrome: "Content Transformation Error Proxy cannot apply content transformation.This could be caused by a misconfiguration, or possibly a response with an unknown content encoding." When this has happened on previous versions I disabled the Brotli Content Encoding in the Chrome://flags, and was able to view content as normal, but this setting no longer appears. This is of particular problem when trying viewing some forums (https) and YouTube content, which now no longer works. I have no control over the company Proxy/Firewall so cannot change anything there, and the Chrome version is network distributed and installed, so I cannot move to an older version! Chrome is running on Windows 7 (64-bit). I'd be grateful for any help to resolve this issue. Thank you.
