@AakashRaut Hi, Firefox implements web standards for the certificates used to verify secure communication on the web. It would seem your server isn't sending a valid certificate, so you would have to speak to their support about this. - IH

@ChrisHG We hear you – Tab Groups shipped in v137 and Profile Management in v138 but both roll out progressively. To try them now, set browser.tabs.groups.enabled and identity.fxaccounts.handler to true in about:config. Thanks for your patience! -NG

@jansumi We’re aware of overheating & slowdown on Big Sur with video sites. Disable Hardware Acceleration (Preferences > General) & restart Firefox. If it’s still hot/sluggish, launch in Troubleshoot Mode to rule out add-ons. Make sure macOS & Firefox are updated -NG

@YMsabbag Tab grouping is rolling out gradually starting in Firefox 137! 🎉 It may take some time to reach all users, so keep an eye out for updates. Let us know what you think once it’s available to you! -NG

@NofiyTheFox We hear you 😅 — it took time to get it right, but Profile Management is here and it’s just the start. -NG

@SMSeddy Good news! Tab Groups just arrived in Firefox 138 on April 29 🎉. You can create, name, color-code & drag groups to organize tabs—no extensions needed. Update Firefox to try it out, and share your feedback. -NG

@malithmadhushan Thanks for the feedback! We’re exploring ways to streamline Profile Management in Firefox, aiming for one-click access and a more intuitive switcher—similar to Arc’s fast, seamless flow. Stay tuned for updates, and keep letting us know what features matter most! -NG

@seiyuu1119 Thanks for the update! Since everything’s up to date and no add-ons are installed, try launching Firefox in Troubleshoot Mode (from the Help menu) to see if it still happens. Let us know what you find! –NG
