Comments on Firefox Fast & Private Browser for Android
★★★★☆Vincent Lionheart· Aug 17, 2026
Hi! I just want to add something. Can you add a "tab group bar," so we can easily switch between tabs in a tab group? Also, can you add an option to open new tabs straight into the tab group when hold-clicking and selecting the option inside one of the tabs in the group? So, I don't have to open those new tabs outside the tab group and manually put them inside the tab group. And also, like I said before, please make tab groups available while browsing privately. Thank you very much, Firefox!

I have left Chrome. I'm experiencing too many issues after last update.
★★★★★DeeDee Viera· Aug 12, 2026
I've been using Firefox for a few months now, and I don't know why I didn't use it earlier. My husband was the one who put me onto Firefox noting its ease of use and respect to consumer privacy as his fave features. I agree. Firefox is a straightforward browser, does not have "noise" with ads, and is easy to use and navigate. I missed being able to group my tabs when I first started using Firefox, but with the recent updates I can group tabs again! Very happy with the new updates. I 5/5 recommend
★★★★★Andrew Atkinson· Aug 12, 2026
Take back control of your privacy and don't give everything to Google and chromium. Firefox is really great.
★★☆☆☆Gray Fox· Aug 4, 2026
The sheer amount of AI nonsense in Firefox just isn't good, and to be honest, Firefox has become quite slow and bloated. I've considered switching to alternatives like Firefox, Water fox, or even Brave, because Firefox isn't really the browser I recommend anymore. It used to be a go-to recommendation, but honestly, I've changed my tune. I'd definitely steer people away from it now.
★☆☆☆☆S YT· Aug 12, 2026
Why does every download need me to confirm where it's saved, why did you guys change it was fine, are you guys not testing before shipping changes, even AI with basic UI/UX skill would have found this?
★☆☆☆☆C B· Aug 7, 2026
FireFox is the only browser I trust, but.... Again an update, Aug 2026 is kicking me off and keeping me off Account Sync. So if I can ever get back on, should I quit updating?
★☆☆☆☆Kieran O'Connor· Jul 31, 2026
I hate tab groups, it is SO AGGRAVATING, Mozilla PLEASE PLEEEEEEASE give us the option to disable this on both Desktop and Android Firefox!
★☆☆☆☆Bethany Ingram· Jul 31, 2026
Do not like the new dark theme I do not like the new black dark theme, it causes eye strain for anyone who is migraine prone. Please bring back the gray option!
