Support
Premium, payment, cancellation, display problems: answers to the most common questions. If yours isn’t here, I’ll answer you personally.
Premium
Premium and payment
I’m Premium but the extension doesn’t recognize it
Open the extension and click the Premium login button:
- Dark Mode FR: « Déjà Premium sur un autre ordinateur ? Se connecter » (“Already Premium on another computer? Log in”)
- SpeedMaster: “Already Premium? Log in”
- StreamMaster: “Already Premium? Log in”
Enter the email address you paid with, then click the link you receive by email. Premium turns on by itself. If nothing changes, write to support and include that address.
How do I get Premium back on another computer or after reinstalling?
Premium is linked to your email address, not to your computer. Install the extension, click the Premium login button and enter the email address you paid with. You don’t pay a second time.
How do I cancel my subscription?
The subscription button opens the ExtensionPay page, where you can cancel in one click:
- Dark Mode FR: « Abonnement » (“Subscription”), at the bottom of the extension window
- SpeedMaster: “Manage Subscription”, on the extension’s Premium page
- StreamMaster: “Subscription”, in the extension’s Settings tab
Premium stays active until the end of the period you’ve already paid for. You can also ask for cancellation at contact@flavienhue.fr.
Can I get a refund?
Yes. You have 14 days after paying to ask for a full refund, no reason needed, even if you’ve used Premium. Write to contact@flavienhue.fr with the email address you paid with and the extension concerned.
What plans are there, and can I switch?
All three extensions have the same prices: €0.99 a month, €4.99 a year, or €9.99 once for lifetime access. To switch plans, cancel your current subscription, then choose the new plan in the extension, or write to me and I’ll take care of it.
Does one Premium purchase cover all three extensions?
No. Each extension has its own Premium: buying it for SpeedMaster doesn’t unlock Dark Mode FR or StreamMaster.
Is payment secure? Where are my card details?
Payment goes through ExtensionPay and Stripe. The extensions never see your card details: only your email address is used to link Premium to you. More details in the privacy policy and the terms of sale.
Troubleshooting
Common problems
The extension does nothing on the open page
Reload the page: after an install or an update, Chrome only applies the extension to pages opened afterwards. Also check that the extension is turned on in chrome://extensions.
I can’t find the extension icon
Click the puzzle-piece icon to the right of the address bar, then the pin next to the extension’s name to pin it.
How do I get the latest version?
Chrome updates extensions on its own, usually within a few hours of a release. To force an update: open chrome://extensions, turn on Developer mode at the top right, then click “Update”.
My settings are gone
Settings are saved in your browser. They’re deleted if you uninstall the extension or clear your browser data. Premium, on the other hand, can be recovered with your email address.
Do the extensions work on Edge, Brave or Opera?
They’re published for Google Chrome. Chromium-based browsers (Edge, Brave, Opera) generally accept extensions from the Chrome Web Store, with no guarantee. Firefox and Safari aren’t supported.
Still stuck?
To help me fix the problem the first time, please include if you can:
- the extension and its version (shown in chrome://extensions);
- the site where the problem happens, with the page address;
- a screenshot if it’s a display problem;
- the email address you paid with if your question is about Premium.
