Modify Header Value (HTTP Headers)
Extension Actions
Add, modify or remove a header for any request on desired domains.
Modify Header Value is an extension that can add, modify or remove an HTTP-request-header for all requests on a desired website or URL. This add-on is very useful if you are an app developer, website designer, or if you want to test a particular header for a request on a website.
Key features:
1. Easily add, modify or remove a header for any request on desired domains.
2. For a complete list of HTTP headers, please take a look at the list of all HTTP Header Fields on the Wikipedia page (https://en.wikipedia.org/wiki/List_of_HTTP_header_fields).
3. Clicking on the Toolbar icon opens a UI to quickly switch the add-on ON or OFF, or open the options page.
4. Each header item has several options to adjust (see add-on's Options page for details)
5. You can add several header items and active or inactive them separately.
6. An example in the options page shows a tutorial on "How to add a custom header".
Note: in order to submit bugs, please visit the add-on's homepage (https://mybrowseraddon.com/modify-header-value.html) and fill the bug report form.
Latest reviews
- Jonas
- DO NOT INSTALL THIS! The addon is either compromised or was a sham from the start, when added, you will get fake phishing "Security verificaton" sites with supposed captchas.
- Richard
- Doesn't modify the headers you probably need to. Appears to be unsupported.
- Iain
- This just works. Documentation is very good
- Johan
- Good. Does what it says, and the domain vs URL feature is very useful.
- Steve
- Has potential but does not work for some common headers like Accept-Language. Also the supporting site is dead so this extension is likely at a dead end.
