[FR] ÉDIT : Le développeur a publié une mise à jour environ 8 heures après mon signalement. Le problème est corrigé proprement : le User-Agent n'est désormais modifié QUE sur les onglets où l'émulation est explicitement activée, et plus globalement. Cloudflare fonctionne à nouveau normalement. Bonne réactivité du dev, note remontée de 1 à 4 étoiles. [EN] EDIT: The developer published an update about 8 hours after my report. The issue is properly fixed: the User-Agent is now modified ONLY on tabs where emulation is explicitly activated, no longer globally. Cloudflare works normally again. Good developer responsiveness, rating raised from 1 to 4 stars. — Critique originale / Original review — [FR] Cette extension modifie le User-Agent du navigateur de façon globale et permanente dès qu'elle est activée, sans action de l'utilisateur et sans se limiter à un onglet d'émulation. Conséquence : navigation impossible sur tous les sites protégés par Cloudflare (boucles de challenge infinies, blocages). Comportement non mentionné dans la description. À désinstaller — Firefox intègre un mode responsive natif (F12 puis Ctrl+Maj+M) qui fait le même travail proprement. [EN] This extension modifies the browser's User-Agent globally and permanently as soon as it is enabled, with no user action required and no restriction to a specific emulation tab. Consequence: browsing becomes impossible on all Cloudflare-protected websites (infinite challenge loops, blocks). This behavior is not mentioned in the description. To be uninstalled — Firefox already includes a native responsive design mode (F12 then Ctrl+Shift+M) that does the same job cleanly.
