il y a un rond rouge avec une barre s installe mais fonctionne pas

I cannot have a 2-space-width tab.

Not open-source, unfortunately.

Simply doesn't work anymore. Click on the button and it looks like the window wants to open, but never does...

its not showing up on the top right can someone help?

Was inspiring in old ages. Nowadays this addon has heavy sclerosis about scripts I carefully collected and installed. Every time I look into dashboard: no scripts installed?! I'm migrating back to GM.

It has become Non Working in Firefox after a Browser Update. It is showing installed but DOES NOT WORK!

A mi tampoco me funciona. Tras pulsar el boton negro, se abre el rojo para empezar la descarga del MP3 pero no hace nada.

Depuis le gros bug de Firefox le 5 mai 2019 que tout le monde a eu : il desactivait toutes les extensions.Mozilla a fait une mise a jour de firefox corrigeant ce bug,ben depuis j'ai plus accés a mes scripts tampermonkey,il n'y a pas l'option elle a disparue!!! je ne vois donc plus du tout mes scripts!!! Du jamais vu,firefox empire!!! Que faire???aidez moi

It used to work alright, but sync has been disabled for Firefox from TamperMonkey's end and nobody's been answering the support address in the last month. It just opens a broken OAUTH token window and refuses to sync in either direction. Sync is the whole reason I'm using the extension.

EDIT: Already switched to Violentmonkey because it's open source and has better maintainership that appears to be responsive to users. TamperMonkey should respond on its official contact email and be more transparent about what's happening with the addon.

Tampermonkey has not been working for about 2 weeks. Are you going to fix it so we can use it again? when it was working I would rate it a 5

Please be aware that this add-on is not open source.
As an alternative I found Violent Monkey which is open source and seems to work just as fine. Also, every userscript you install may be spyware. Be careful!
