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 keep getting this plug for Capital One shopping add-on. I keep rejecting it, but keeps coming back. I do have Capital One card - but not sure how connected those two are.

Let me know if you have good experience with this thing. Thanks.

Hello, I’m here to ask, how do I install extensions? I have the Firefox app downloaded but when I try to install BTRoblox, Roblox+, and etc. It shows me an “Download Firefox and get the extension”. Now, I think there’s an issue with the add-ons memory card. Because it would take me to a page of mozilla.org. And there the only thing it’s says is “Almost there! Now finish installing Firefox.” Even if I have the app downloaded, I’m on an iPad and I need multiple extensions to download. How do I fix this?

Good Morning! I've just come back to FF after using another browser for quite a few years. Things have changed alot here, but I'm loving it all so far! With that being said, have been trying to get a few extensions set up. Main one being Open Link with New Tab. (WHY doesn't FF do that automatically? lol.) Anyway, obviously I'm doing something wrong because it just stays grayed out. I've uninstalled/reinstalled quite a few times. I know it's something so basically simple and I'm overlooking it. HELP! Thanks! Lynn

Description: I need help with the "Firefox Multi-Account Containers" extension.

The extension is installed and shows as "enabled" in my Add-ons Manager. However, the colorful container icon does NOT appear on my toolbar, so I cannot access or use the extension at all.

What I have already tried (none worked):

· Dragging the extension icon from the puzzle menu to the toolbar · Right-clicking on the extension icon (inside the puzzle menu) to see if there is a "Pin to Toolbar" option — but the option does NOT appear at all · Restarting Firefox multiple times · Restarting my computer · Creating a new profile in about:profiles and testing the extension there — still no icon · Disabling and re-enabling the extension

The extension is installed and enabled, but without the toolbar icon, I cannot create containers or separate my Gmail accounts. I really need this feature.

I have read that this might be a bug in recent Firefox versions. Is there a known fix? Do I need to completely uninstall Firefox and reinstall it? If so, could you please guide me on how to do a clean uninstall (removing all profile folders and registry entries) and then install the latest version?

My system is Windows (older version, if that matters).

Thank you very much for any help!
