There are a couple of potential fixes - read below.
1) Make sure you are using YouTube.com with a secure https connection. TubeBuddy only works over a secure connection so if you see "http://www.youtube.com" change your browser url so there is an "s" after "http" ---> "https://www.youtube.com"
2) If you are in Incognito Mode in Chrome, you have to manually allow TubeBuddy to run in Incognito mode by going to chrome://extensions and selecting the option:
3) Sometimes in your extensions list it will say "Fix" next to TubeBuddy and you will need to click that. Go to chrome://extensions/ in your browser and scroll down to find TubeBuddy and see if you see a "Fix" notification.
4) At times, simply uninstalling and reinstalling the extension fixes an issue. Go to: chrome://extensions/ then click 'Remove'
You can then reinstall the extension here -https://chrome.google.com/webstore/detail/tubebuddy/mhkhmbddkmdggbhaaaodilponhnccicb
5) There could be a chance that another browser extension that you have installed is conflicting with TubeBuddy. Try disabling all other extensions, refreshing YouTube, and see if TubeBuddy shows up. If so, start adding them back one at a time (and refreshing YouTube) until TubeBuddy doesn't show up and you can identify which plugin has the problem. Send us a link to the plugin and we will work to ensure the two programs play nicely.
6) If you're still not up and running, please email us the following information:(support@tubebuddy.com)
- What browser you're on (Chrome, Firefox, Edge) and Operating System (Windows / Mac)
- Try a different browser. If you are on Chrome, try installing Edge. If you're on Edge, try Chrome. Do other browsers work?
- Our browser extension is not compatible with Firefox; if using Firefox, please install to Chrome or Edge instead.
- Our extension utilizes Manifest V3, which is supported in Chrome 88 or later. Please ensure you are using a compatible version of Chrome to experience full functionality.
7) lf you have PrivacyBadger installed, you will need to uninstall it.
