2026-08-08 Ne***** Last update was 3 years ago and it's dead. I tried the fix given by other reviewers and got the popup to open, but when you toggle the on/off switch it doesn't effect the extensions at all. Man I wish FF had a decent extension manager.

2026-02-07 Fi***** ** DISCARD MY FIX !! The addon is will NOT allow you to disable/enable your addons from it's own pop-up rendering this extension USELESS. 1 Star: INSTRUCTIONS TO FIX: 1. Right click the Install Button from the Firefox Addon Store, Save the xpi to your computer. 2. Open the xpi with 7-Zip. 3. Right Click the manifest.json file and edit. Find "default_popup": and highlight ALL code to the right and replace with the everything between the brackets but NOT the brackets ["popup/index.html",] now click Save from the Notepad editor. Find the Folder META-INF and Delete it. Exit 7-Zip and say Yes to repack the xpi with your mods. 4. From Firefox Addon select Install from File and find the xpi you just edited. After install it will say this addon is unsigned. 5. You May have to go to about:config and put this in the search bar: xpinstall.signatures.required double click and change to False. * Some people complain you can't Pin to the toolbar. That is true because it is in the Address bar as a Green Puzzle Piece. Any problems with my instructions above, just use any A.i. to clarify. Thanks to Vlad's 1 star comment about the path being broken lead me to this fix. It gets 4 stars even though it's broken because it's the ONLY Extension Manager available on Firefox so big thanks to the person who wrote the code.

2025-11-18 Fi***** 插件无法运行,可以这样解决: 在 everthing 搜索 15bea603-f341-47aa-a925-cb933434fe8e}.xpi 关闭浏览器,将 xpi 修改为 zip 使用 zip 打开 manifest.json,编辑 json 文件,将 "default_popup": "popup.html" 里面的 popup.html 修改为 popup/index.html,最后在拓展里打开调试附加组件,点击「临时加载附加组件」选中修改后的 15bea603-f341-47aa-a925-cb933434fe8e}.xpi
