Hey @The Coding Sloth Did you manage to get this to work? I have a similar case. How can I use the declarativeNetRequest to generate dynamic rules that work on both chrome and Firefox? I want to redirect network calls to my local server JS script when I am prototyping, but when I am not, I want to use a static link to my website, I will have a toggle button to determine which URL to redirect to.

async function setRedirectRule(newRedirectUrl: string) {
  let newRedirectRule: chrome.declarativeNetRequest.Rule = {
    id: RULE_ID,
    priority: 1,
    action: {
      type: chrome.declarativeNetRequest.RuleActionType.REDIRECT,
      redirect: { url: newRedirectUrl }
    },
    condition: {
      urlFilter: "*://*/*",

      resourceTypes: [chrome.declarativeNetRequest.ResourceType.MAIN_FRAME]
    }
  }

  try {
    chrome.declarativeNetRequest.updateDynamicRules({
      removeRuleIds: [RULE_ID],
      addRules: [newRedirectRule]
    })
    const currentRules = await chrome.declarativeNetRequest.getDynamicRules()
    console.log("Redirect rule updated")
    console.log("Current rules:", currentRules)
  } catch (error) {
    console.error("Error updating redirect rule:", error)
  }
}

async function setRedirectRule(newRedirectUrl: string) {
  let newRedirectRule: chrome.declarativeNetRequest.Rule = {
    id: RULE_ID,
    priority: 1,
    action: {
      type: chrome.declarativeNetRequest.RuleActionType.REDIRECT,
      redirect: { url: newRedirectUrl }
    },
    condition: {
      urlFilter: "*://*/*",

      resourceTypes: [chrome.declarativeNetRequest.ResourceType.MAIN_FRAME]
    }
  }

  try {
    chrome.declarativeNetRequest.updateDynamicRules({
      removeRuleIds: [RULE_ID],
      addRules: [newRedirectRule]
    })
    const currentRules = await chrome.declarativeNetRequest.getDynamicRules()
    console.log("Redirect rule updated")
    console.log("Current rules:", currentRules)
  } catch (error) {
    console.error("Error updating redirect rule:", error)
  }
}

If I put this into the background.ts it works for chrome, every time I open a new tab it just redirects to google. But it doesn't work for firefox. This is in my package.json:

"manifest": {
    "host_permissions": [
      "https://*/*"
    ],
    "permissions": [
      "tabs",
      "declarativeNetRequest"
    ]
  }

"manifest": {
    "host_permissions": [
      "https://*/*"
    ],
    "permissions": [
      "tabs",
      "declarativeNetRequest"
    ]
  }
