[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.

perfect

Mostly works as intended, has password protection of rules which is great, sometimes (rarely) allows a site to be displayed, usually just one page (so if you navigate it corrects)
