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!

Latest reviews (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!

It solved my problem in upload file XHR requests was rejected on Azure notebook giving 500 internal server error because of wrong content-length value. just put content-length and it worked perfect (2019-02-20) Sai Babu: I would be perfect if we can export all profiles once and add it later in time or may be in another system all at once. (2019-02-20) Incredible plugin, fantastic responsive developer. (2019-02-12) Ruslan Mostov: Works fine for Google Chrome and Chromium but NOT for Vivaldi?
