★★★★★ Firefox user 13007505 · 23 May 2026 · v36.0Update: It does work now after several sign ins. In box appears, but as soon as you enter an email this message pops up. "Recent Gmail changes require you to re-authenticate with your Gmail <Sign-in>"

★★★★★ Kai Dedo · 23 Apr 2026 · v35.0.1.1Bardzo dobry dodatek. W Firefox natomiast nie działają powiadomienia. W systemie ten dodatek się nie pojawia. Wielka szkoda. O ile w Microsoft Edge powiadomienia działały o tyle w Firefox zero. Bez powiadomień można żyć bo w pasku narzędzi ikonka reaguje na nowa pocztę. Dziękuje.

★★☆☆☆ Larry · 8 Apr 2026 · v35.0.1.1I've revoked my original 4-star review - here's why: It seems the recently updated extension no longer supports the Firefox ESR channel for older PCs that can't run Windows 10/11. The extension was working fine until 7th April 2026, then on that day a new version installed automatically, and now it's just a mass of error messages ... all of them in a bold white font on a bright red background. The messages rapidly accumulate down the screen, over the top of emails, rendering the extension near-useless.

★☆☆☆☆ VV · 7 Apr 2026 · v35.0.1.1Decided to 'update' it to disable any interaction with emails when it's incessantly requesting relogin... well, if you're so desperate for 1/5 stars, here it is...

★★☆☆☆ Firefox user 18619995 · 23 Feb 2026 · v33.1.3.1Janky plugin that doesn't allow you to change the order of your email accounts unless you add them in manually - and then you are limited to 3 accounts before you have to give him money. Bait and switch. Uninstalling.
