I downloaded an extension and can't do anything with it. There is no way for me to open it, all I can do is open up my extensions to see it then change permissions or delete it. It won't appear on my toolbar with other extensions. I've seen others ask this question and the solutions dont apply to me. People are being told to either right click and click pin to toolbar or to click the gear icon next to the extension and then pin to toolbar as well. I have no gear icon next to extensions and right clicking an extension treats it like a link. There is a gear at the top that when I click it I can click "manage extension shortcuts" only for it to then pretend none of my extensions have shortcuts even though 2 of them are right there in my toolbar. The 3rd 1 mozilla seem to not want me to have on my toolbar.

Please tell me how to disable adblocker for a site. I am trying to read my local newspaper and I cannot access it due to this issue. I've googled it and cannot find the answer. Please Help!!!

Hello,

I am encountering an interface display issue while using the AdGuard ad blocker extension in the Firefox browser on Windows. When I try to open the "Filtering Log" feature within the extension, the pop-up window appears completely blank and fails to display any log content.

Steps to Reproduce the Issue:

1. 1 Install and enable the AdGuard extension from the official add-on store.
2. 2 Browse any website.
3. 3 Click the AdGuard icon in the Firefox toolbar.
4. 4 Click the "Filtering Log" button (the icon that looks like a list or clipboard).
5. 5 Expected Result: The filtering log window should open normally, displaying a list of blocked and allowed requests.
6. 6 Actual Result: A new window pops up. The title bar of this window displays "Mozilla Firefox," but the content inside the window is completely blank (pure white, without any text or error messages).

Additional Information:

• Firefox Version: 142.0.1 (64 bit)
• AdGuard Extension Version: 5.1.139 (TSWebExtension v3.1.0-alpha.4 TSUrlFilter v3.3.3 Scriptlets v2.1.6 ExtendedCss v2.1.1)
• Operating System: Windows 10 22H2

Other Installed Extensions:

• Immersive Translate - Translate Website & PDF | by Immersive Translate | Version 1.20.8 | https://addons.mozilla.org/en-US/firefox/addon/immersive-translate/;
• Tampermonkey | by Jan Biniok | Version 5.3.3 | https://addons.mozilla.org/en-US/firefox/addon/tampermonkey/;
• Dark Reader | by Dark Reader Ltd | Version 4.9.110 | https://addons.mozilla.org/en-US/firefox/addon/darkreader/

Troubleshooting Steps I Have Already Attempted:

• Restarted Firefox.
• Disabled and re-enabled the AdGuard extension.
• Reinstalled the AdGuard extension.
• Tried running Firefox in Safe Mode (with all extensions disabled). The issue persists, suggesting it may not be a conflict with other extensions.

This issue prevents me from using AdGuard's core debugging functionality. Thank you for your assistance.

Audio Equalizer and Amplifier(https://addons.mozilla.org/ru/firefox/addon/audio-equalizer-and-amplifier/) extension on Yandex Music(https://music.yandex.ru/) doesn't work, which was noticed only in Firefox. In other browsers, it worked correctly and without any problems, I don't understand what the problem is. PC rebooted, browser restarted, the extension uninstalled and installed again. How can this be fixed? The extension worked correctly in Chrome and Edge.

Hi again, your answer didnt help - below you see the message I get when trying to book a flight on sas.se

kind regards Jan Collborg

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.

Dear Mozilla Firefox Team,

I hope this message finds you well.

I would like to start by expressing my deep appreciation for the Firefox browser. I truly admire the values Mozilla stands for, especially regarding user privacy and open-source development. Firefox is fast, secure, and beautifully designed — and I would love to use it as my primary browser.

However, there is one major challenge that prevents me from doing so: extension compatibility. Many of the tools and extensions I rely on for my daily work are either not available on Firefox or do not function as they do on Google Chrome.

I understand that Firefox has its own extension ecosystem and architecture, but I sincerely hope that your team could explore a way to bring full compatibility or at least broader support for Chrome extensions. This feature alone would make Firefox the perfect browser for users like me who value both productivity and privacy.

Thank you for all the hard work and innovation you bring to the web. I look forward to seeing how Firefox continues to evolve.

Best regards,

Hello, just curious, I've submitted a few of my extensions to be recommended, and it's been awhile.....how long does it normally take for a team member to review the submitted extensions? Does anyone let the creator know if their theme has been approved to be "recommended" or rejected?

Whenever I try to log into my Eset Password Manager it says unable to log in offline. Yet Eset password manager works on other browsers. I have refresh the browser and removed and re add the Eset extension.
