WebExtension | A proof-of-concept webextension for verifying JS integrity | Cryptography library

I'm developing an easy addon for the browser for exercise since I'm new on javascript and I'm reading documentation related to the topic by https://developer.mozilla.org/en-US/docs/Web/API

My purpose is able to replicate the "Copy as cURL" of the Network tab inside the Browser devtools inside a context menu that I'm creating.

For example if I consider a "Copy as cURL" command by https://stackoverflow.com (by using Firefox 91.5.0esr (64-bit)):

I'm getting started with addon development on Firefox and have trouble making the debugger work.

I'm using Visual Studio Code 1.65, with the extension Debugger for Firefox (version 2.9.6), on a Debian machine, with Firefox 91.6.

I use this standard, unmodified, run configuration:

Currently I'm working on my own Firefox extension and I've met the problem with adding listener to an onclick event for a context menu item.

manifest.json

Firefox allows us to apply filters like tabId, urls to requests before intercepting them using webRequest.RequestFilter

So far so good. The problem is this code

I am building an extension in Thunderbird with UI element message_display_action for my school project. I am wondering if I can access full email source code from java script file that I am using for building up my html page when pressing on button my extension. I found a funciton named getFull(messageId) in documentation at https://webextension-api.thunderbird.net/ but I don't understand how to use that function and I don't even know what messageId is. I know it is a integer but I don't know how to get that integer for a specific email. I entered permission (messagesRead) in my manifest file of extension for reading emails but i still don't know how to use that function. I didn't find any examples or tutorials on the internet so if anyone can help me or atleast point me to the right direction.

UPDATE: I realize now that in the scenario described below I will need to be careful of infinite loops since the page being redirected to is the same (minus the added param) as the initial page. Does anyone have any experience with that in Webextensions and can offer any advice on how best to avoid these loops?

I've written a few Webextensions for Firefox before but it's been a few years (a little out of practise). But a new problem has arisen for which I can see no solution except to write my own Webextension.

How would I modify the URL of a page and add a query parameter? I am specifically trying to modify the URL of Google Docs pages and add the query param ?mode=html

So for example, a Google Docs URL might look like: https://docs.google.com/document/d/7Ujfjsd69To7lInXFOdn49nAxLLhfn43fj43JHDTp87/edit

I am looking to create an extension that will modify that URL so it becomes: https://docs.google.com/document/d/7Ujfjsd69To7lInXFOdn49nAxLLhfn43fj43JHDTp87/edit?mode=html

(Obviously I only want this param appended when the URL being loaded matches https://docs.google.com/document/d/*)

Can anyone give me a pointer on how to start that? What extensionAPI function(s) would I need to use to do that? At what point in the lifespan of the request should it happen etc?

I want to use typescript + Vue 3 to develop a google chrome extension. In the google chrome extension popup index, the typescript code index.ts looks like:

Here is my background script;

I've been working for few months with QTP (UFT One 15.0.2), and today it has stopped recording (when I do the actions no lines are written in the script and no objects are added to the objects repository) and recognizing objects with the spy feature.

I am using the WEB add-in, and as I've been working for months with Mozilla Firefox I have checked that the WebExtension.xpi is well added to the browser.

I've tried to open mozilla before and after UFT One, I've also restarted my computer, I've checked the size of the screen browser is 100% and that in the Record and Run Settings the option " Record and run on any open browser" is checked for Web.
