User Reviews
This one is the best i've tried from current extension offering.
Css with color scheme make instant changes, js after closing the editting window. Thats ok. Only the font could be smaller. Thank you.

I am honored to be the first review of this add-on.
This injection is invaluable as it can complement and execute scripts that currently do not work with Tampermonkey and Greasemonkey.
I have a request.
① Please implement the error syntax detection function additionally.
---
② Also, I would like to request the addition of an edit screen for inserting into all WEB domains starting with "http".
Especially the editing screen of "JavaScript".
Please add a function that can execute "script to be executed for each domain" and "script to be executed for all WEB pages" at the same time.
---
By the way, I think it is necessary to change the editor screen so that it opens normally even from the outside of the toolbar.
--------------------------------
私はこのアドオンの最初のレビューになることを光栄に思います。
このインジェクションは、現在TampermonkeyおよびGreasemonkeyで機能しないスクリプトを補完して実行できるため、非常に貴重な存在です。
リクエストがあります。
① エラー構文検出機能を追加で実装してください。
---
② また、"http" で始まるすべてのWEBドメインに挿入するための編集画面の追加もお願いしたいと思います。
特に「JavaScript」の編集画面です。
「ドメインごとに実行するスクリプト」と「すべてのWEBページで実行するスクリプト」を同時に実行できる機能を追加してください。
---
ちなみに、ツールバーの外側からでも正常にエディタ画面を開けるように修正する必要があると思います。

Is WebsiteInjector Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
WebsiteInjector requires a few sensitive permissions. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
- High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
WebsiteInjector has earned a fairly good reputation and likely can be trusted.
Risk likelihood analysis details
- High This extension has low user count. Unpopular extensions may not be stable or safe.
