Modify Headers for Google Chrome™

Image from store Modify Headers for Google Chrome™
Description from store A simple and easy to use extension to allow Add, Modify and Filter of HTTP headers. Install, click on the icon to go to the options page. Add - adds the header to the existing list of headers Modify - will replace the value of the header if it exists Filter - will remove the header if it exists The master start/stop button on the top of the page will enable/disable the entire extension The on/off buttons on the row will turn the directive on that row on/off. You can export the data from the Firefox extension and import here and vice-versa. This is inspired by the Firefox Modify Headers plugin by Gareth Hunter (https://addons.mozilla.org/en-US/firefox/addon/modify-headers/) Change log: v2.0.6 Changed UI to show STATUS of the entry in a different color v2.0.5 Fixed export v2.0.2 - Made some changes to UI to help with usability v2.0.1 - Fixed icon color discrepancy for Start/Stop on table - Fixed issue with headers loading multiple times on tab reload v2.0.0 - Revamped UI - Opens Options page from Browser icon directly - Export/Import the Header list for portability with the Firefox plugin - Type-ahead of commonly used headers - Fixed issue: Need to open options page to start plugin when browser restarted

  • (2020-09-10) Tony B: Worked great and was relatively easy to figure out. Nice extension! One note, I was trying to put an Authentication header on my request and I needed the Scheme and Parameter to be populated. I just needed to add one entry for Authentication and then the two entries are space delimited. For example, I put Authentication in Name field and "Bearer thetoken" in value field and then Bearer got populated to Authentication.Scheme and thetoker was in Authentication.Parameter. Just in case this saves anyone some time.

  • (2020-01-23) Monir khan: Hi, i wanted to add a filter, not available.. I want to remove / not include X-USERID header from a css <link> in <head> in index.html. But filter not available. Switching to Mod-header instead
  • (2020-01-17) Nikos Papastefanakis: First of all it works and I like it. Thanks for the tool guys!! Suggestion: It would be a good idea to apply the headers for specific domains and NOT for any domain. So if you add an extra param in each row for the domain to apply to that would resolve the problem I am describing below. You could set the val asterisk "*" for all domain by default (as it is today) and let the user modify the val for a specific one -> Impact: My google hangout and chat.google.com crashed for two days because of this plugin. It was not connecting and I was getting a "no connectivity" status. After a lot of digging and tests I managed to locate the problem and it was this plugin. When I stopped it the hangouts recovered in a second. hope this helps other people.

  • (2019-08-29) Ozornick: Ребят. Чтобы работать с расширением откройте вкладку, нажав на иконку. Жмете Play сверху и Add new. Настраиваем данные, жмем Save. Рядом подтверждаем заголовок Enable и он включается во все запросы от вас. ВСЕ! Так трудно понять это?! Далее этот заголовок посылается ВСЕМ страницам

  • (2019-08-13) Stefan Verweij: Since Chrome 76, this plugin can throw CORS errors on some websites, causing things like fonts to not load properly. @Anil Kommareddi see this post for info on how to update the plugin and avoid these errors https://support.google.com/chrome/thread/11089651?hl=en

  • (2020-09-07, v:2.0.7) Tiago Duarte: help with chrome changing header in code
    hi. I tried your extension for chrome and works nicely. I actually need to try and prevent chrome from auto-uppercasing a certain header value, as it crashes my application. do you think you can let me know if there is a way to stop chrome from doing this, either through code, or in the chrome settings? any help is appreciated. thanks.

  • (2020-01-06, v:2.0.7) Brian Van Hooser: Manifest version still v2
    I'm using your extension via Selenium and it appears that one of the Chrome updates officially blocked the usage of v2 crx packages. Can you please update to v3? It'd really help out.

  • (2019-09-28, v:2.0.7) Sachin goa panjim: ITS NOT WORKING
  • (2019-09-10, v:2.0.7) Stefy Kyra: Improvements
    This is a great extension overall. Few improvements to consider: 1) Imho I think that there should be a way to signal if the extension is running or not outside the extension page, maybe change the extension icon to something visible/flashy so it can be seen if it's running without the need to open it. 2) A "group by" or/and "sort" functionality would be really great or at least 3) a way to move the headers up and down so they can be grouped manually. 4) A default value for the action field ("Add" maybe or configurable). Personal preference: it's a bit annoying that this is not a popup extension, but a new tab instead, anyway keep up the good work!
  • (2019-08-30, v:2.0.7) Žiga Škrabl: Extension is corrupted after chrome update....

  • (2019-08-08, v:2.0.7) Madhuresh Krishna: Could not modify headers in Version 76 of Chrome
    I'm using a custom header 'x-my-user-agent'. It doesn't get added to the HTTP header. My version of google chrome is "Google Chrome is up to date. Version 76.0.3809.100 (Official Build) (64-bit)" I did check the headers with a C# program. Couldn't find the headers even though it is enabled. Any help is much appreciated.
  • (2019-08-08, v:2.0.7) Raphael Martins: Plugin makes button on all sites stop working

  • (2019-07-20, v:2.0.7) Carl Lorentzen: Extension no longer working for X-Forwarded-For
    I used to rely on this extension for X-Forwarded-For, to test geolocation by IP. Unfortunately as of very recently, it no longer seems to work. No matter which X-Forwarded-For IP rule I activate, my IP remains unchanged. I've seen this issue on more than one computer with the extension installed. Not sure if a recent Chrome update is impacting the extension's functionality?

    I need to add the print time/current system time to printed pages in Chrome. (preferably in top right corner of page using 24-hour format) Is your extension able to do this? How? Either I'm missing something very basic, or my brain simply refuses to work. Can you help?
