Works only for first request to page???

Was alternatively using requestly to handle this specific use case, but with the direction they've been going this has been a really nice alternative

As Security Researcher, I've found this add-on very useful.
I never even had any bug or issue.
Absolutely 5 stars!! <3 💯 ❤️

Extension now breaks youtube if you change the "User-Agent" header just to make people aware

never did this previously so either something changed with the extension or youtube changed something

It is a failure. I am unable to work around the stupid CORs protection with addon to test code in console. The ui also needs some refinement.

Just need to be able to edit a header after is added to be 5 star plugin. For now I'll just give 3

期待已久的更新（0.1.8），但是“选项页面”没有半点更新。
The long-awaited update（0.1.8）, but the “Options Page” has not been updated in the slightest.

①与Edge版本相比，Firefox版本的选项页面看起来不那么整洁。
①The options page of the Firefox version looks less neat compared to the Edge version.

②无法快速全选TextBox内容。
由于上述原因....修改URL&Header Value数值过于困扰。

②Unable to quickly select all TextBox contents.
For the above reasons....It is too troublesome to modify the URL&Header Value value.

挺棒的插件，唯一的缺点：Chrome版4月份已更新0.1.8。
Great plugin, only downside: Chrome version has been updated to 0.1.8 in April。

awesome, using it to add a specific header which Nginx uses to authorize the webbrowser and trowing a 404 if missing

Got to say like using this software it does the job and does it good and allows you to tweak any header you desire. Good job!

Great and usefull exention. Thk.

Cool extension, which works in private mode! This was very important for me (private mode) and other popular extension didn't work.
So, I recommend this!

Please add an option to edit response headers as well and export and import rules so I can replace "Header Editor", I will be watching for updates
