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. ** Firefox addon ** https://addons.mozilla.org/addon/modheader-firefox/ ** Donation ** https://www.paypal.com/pools/c/84aPpFIA0Z ** Source code ** https://github.com/bewisse/modheader ** User guide ** https://bewisse.com/modheader/help/ ** Other Chrome extension by the same developer ** https://bewisse.com/ If you think this extension is useful, please share it!

(2020-02-21) BC A: 目前遇到的最好用的。本来是用Charles的Rewrite功能，但或许是我电脑的网络状况太复杂（同时梯子，Proxifier，VPN，SwitchOgema），Rewrite很奇怪的对某些请求不生效。因此用了这个扩展。目前能满足需求。

(2020-01-30) Rob Graham: It used to be really responsive but now when i'm trying to turn headers on or off, it's not visually showing at times, or when i try to type into the input fields, nothing shows until after I click away then suddenly my input displays...
(2020-01-29) Jorge Revés: Profile switching stop working a few time ago.
(2020-01-22) Drew McMillan: Good at what it does, but recently it's been very unresponsive when changing the headers. Has really strong input lag, especially when adding 5+ request headers
(2020-01-22) Rytt O.: Pretty good, other options do too little or do too much for you.

(2019-12-12) Ryan Steller: Stopped working a few days ago.
(2019-11-19) james pj: The extension works perfectly. Only thing that it applies the headers to all sites. I can see an option in the extension settings page saying "Allow this extension to read and change all your data on websites that you visit:" But, the problem is I cannot enter http://localhost the field says invalid domain.
(2019-10-22) David Salisbury: It doesn't show you the header values that the page is sending! Or the header values that are being sent back! Very limited usefulness.
(2019-10-10) laserraptor: Meddl!
(2019-09-30) 帅小伙: 很垃圾，启动chrome不能自动激活自定义header，非要手动点击才行

(2019-07-23) Serdar Günes: Immer wenn ich eine bestimmte Seite aufrufe kommt folgende Meldung "HTTP ERROR 500", wenn Modheader aktiv ist. Wenn ich es aus mache, erscheint die Seite wieder ganz normal.

(2020-02-08, v:2.5.4) Rakesh Hooda: Not able to use in Selenium
chrome-extension://idgpnmonknjnojddfkpgkljpfnnfcklj/settings.tmpl.html This url is not opening.File not found when opened in Browser to set headers using selenium in 2.5.4 version. Please let me how to open it in chrome to change the values.
(2020-01-21, v:2.5.4) Josh Roberson: Changing the case of my headers!
This plugin is sending all headers added in lower case, when it should not be altering the case from the entered form. This breaks compatibility with some APIs that I use. Please stop changing to all lowercase, and preserve the headers exactly as written!
(2019-12-11, v:2.5.3) Eric Plank: Since update v2.5.3. Completely broken
Does not modify headers anymore since update v2.5.3. Completely broken
(2019-12-11, v:2.5.3) Martin Shameti: Sending Headers to sites on Filter List Broken as of v2.5.3
The headers are not getting passed down to the request as of today's update.
(2019-11-06, v:2.4.1) Vitor Pereira: Configuration provisioning
Is there anyway to provision the extension configuration? Say, for example, using the registry on Windows machines?
(2019-10-14, v:2.4.0) Muhammad Ali: Have you removed the comments column?
i can't find the comments column and it's important as i have the same header name and switch it regularly and can't determine that by the value
(2019-09-04, v:2.4.0) elec tone: How do I disable Brotli Content Encoding in Chrome ver 76.0.3809.100?
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.
(2019-09-03, v:2.4.0) Thomas Haarbach: Header Key lowercase
Hi, if i add the header ModPagespeed=off the key is converted to lowercase. ModPagespeed will ignore lowercase header keys. Also tried with PageSpeed=off. Using Firefox with ModHeaders is working as expected.
(2019-08-21, v:2.3.9) Carmelo Milordo: CORS PROBLEM AND HEADER NOT ADDED
Hi. The header isn't not added in Chrome 76 and plugin version 2.3.9. I always receive error from the CORS policy.
(2019-08-19, v:2.3.9) Frederik Tilkin: Issues since Chrome 76?
Is this what's causing the issues we have since Chrome 76?https://www.chromium.org/Home/chromium-security/extension-content-script-fetches/
(2019-08-06, v:2.3.8) Mike Abell: not working on ajax calls in chrome 76
The header isn't being added in Chrome 76 with ajax calls, however if I open the GET url in the browser directly, it does work.
(2019-08-01, v:2.3.4) jim rose: Broken with cors as of Chrome 76
As of Chrome 76 update, adding custom non-simple request headers seems to be triggering a pre-flight options request, breaking the page unless the server is set up to accept this.
(2019-08-01, v:2.3.4) 西尾健三郎: Chromeアップデートによるハングアウトエラー
