How do I escalate the presence of a malicious extension for removal from the store?

[Coupongogo: Automatic Coupons & Cashback](https://addons.mozilla.org/en-US/firefox/addon/coupongogo-automatic-coupons/) is a malicious extension programed with a command and control server located in China.

Despite [Firefox user reports](https://www.reddit.com/r/firefox/comments/1pl0u6m/malicious_addon_does_not_get_taken_down/), the extension remains available on the Mozilla addon store.

A [rastersec.com contributor explains](https://www.rastersec.com/blog/coupongogo-cryptostealer),

>\[Coupongogo\] operates as a remote-controlled time bomb, utilizing a dynamic configuration system to evade detection, hijack all search and browsing traffic, and wait for a server command to activate its dormant theft capabilities targeting major cryptocurrency exchanges.

Given the lack of success at securing the privacy and security of users by using the standard addon reporting tool, how can I escalate this matter to a responsible Mozilla party for triage?

Firefox Extension: Permission issue while accessing page content (similar to RankingsFactor SEO Chrome Extension)

I’ve developed a Firefox extension similar to the RankingsFactor SEO Chrome Extension, which analyzes on-page SEO elements such as meta tags, headings, links, and canonical tags.

The core functionality works fine in Chrome, but when I ported it to Firefox using the WebExtensions API, I’m facing permission issues while trying to access or read the page content (DOM).

Here’s what I’m trying to do:

Inject a content script to read <meta> tags, headings, and links.

Display this extracted data inside my extension popup.

However, in Firefox, the script doesn’t seem to have proper access to the page DOM — even though I’ve included "permissions": ["activeTab", "tabs", "<all_urls>"] in manifest.json.

I’d like to know:

Are there any additional permissions required in Firefox to read page content?

Does Firefox handle activeTab or content_scripts differently than Chrome?

Is there a specific event or user action needed to grant temporary permissions?

Any help, code examples, or guidance on fixing these permission restrictions would be appreciated.

I am on a Windows 11 machine. Lastpass extension for the Firefox browser does not maintain my vault data. I have to refresh each time I go into the browser. This just started a couple of days ago. Perhaps after installing a new Tmobile gateway? Ideas on how to address/fix?
