I got a big announcement pop-up on Firefox desktop that support for mobile tab groups was added in 153 - https://www.firefox.com/en-CA/firefox/android/153.0/releasenotes/. I'm currently on 153.0.2 (Build #2016175759), and have no tab group feature.

Looking at https://support.mozilla.org/en-US/kb/tab-groups-firefox-android, none of these features are visible for me. Nothing in my tab area mentions groups, the section at the top (private/normal/other devices) doesn't have a "groups" section, and I can't drag tabs onto other tabs to create groups.

My only installed add-on is uBlock Origin. Is there any reason this feature isn't available for me?

I am experiencing an issue where my saved Collections are not appearing on the Firefox Homepage (New Tab page), even though they clearly exist in the system.

The Issue: When I attempt to add a page to a collection, the "Select collection" overlay correctly shows my existing categories: Read Later, News, and Gemini.

The Discrepancy: When I return to the Firefox Homepage, the Collections section is completely missing. Only "Shortcuts" are visible.

Troubleshooting done: I have verified that I have active tabs saved within these collections (as seen in the attached screenshots), but the homepage remains empty below the shortcuts.

Device Specifications:

• Firefox Version: 150.0.1 (Build #2016157687)

Just updated to 152 on Android (152.01 to be precise) and no page summarise features are available - not showing in the settings page, when using the menu (3 dots) on a web page and no shake to summarise either. No shake to summarise gesture under customisation or page summarise under ai controls either.

My language is normally defaulted to system (English NZ) but changing to English UK or Enlgish US doesn’t fix this.

It hasn't been highlighted as a release that's region locked:

"Page summaries: Get key points from long articles with a tap or shake. Now available to all users in English."

Any ideas? A bug?

A "dead" vertical space appears at the bottom of the viewport, pushing site navigation and sticky banners (like "Get started") upward. This occurs globally across different websites, not just one.

Although Firefox for Android has support for PWA websites in general,I see that it doesn't detect all pwa websites and creates a simple shortcut instead! For example go to mytuner-radio.com and try to install it as a Pwa, it just creates a shortcut!

If you try this on other browsers like Vivaldi for Android, it installs it as an app, without the need to open the whole browser alongside all the tabs,every time you tap on its icon !

Please fix this and make all sites that support pwa detectable !

How can I set up a VPN on my Android phone

Please add an UNDO feature to the Android version.

It has happened to me multiple times that when trying to scroll (esp in the bus) it registers as a swipe & deletes a message.

and then it's really hard to scan the trash to figure out which message it was

at the same time, i don't want to be asked for confirmation *every* time i delete something - I'll spend as much time "confirming" as deleting messages.

So the ideal in an undo button somewhere in the interface where a can undo the last action (from a subset, since I'm guessing not every action can be undone). The desktop version has it, hopefully it can be migrated to the android version.

thank you

Hi. So I've been having this issue where, I search something in google, it searches what I asked it to. Then I search again and it finds what I asked it to. The third time if I search again it'll go back to the first thing I tried to search as if i just pressed BACK twice. Something similar happens if I search for something, and then if I search the second thing and tap on the website and then press BACK, it'll go back to the first Google result I ssearched. It's been a few weeks this has been happening and the only thing that'll TEMPORARILY fix it is if I close firefox. If you need any more information I'd be happy to help you help me. Thank you!

I have an Amazon Fire HD (12th gen) and want to use Global Privacy Control. Firefox appeared to be the best option, and I like using Firefox.

I'm instructed to install using Google Play. Went through various error messages on Google (eg, no linked Google account). But I do have a Google account linked to my Fire, through a gmail account.

Finally, Google informed me I cannot download from Google Play to a Fire Device. (I had already allowed Silk to install unknown apps, in Settings.)

The Amazon app store doesn't have Firefox.

What can I do, ideally to install Firefox, but minimally, to use Global Privacy Control on my Fire?

Many thanks.

I just updated Firefox to version 135.0 on my mobile and now I get this really annoying thing:

Everytime I open a tab to go on the YouTube website, it asks me if I want to leave Firefox and use the YouTube app. Every single time. And it even launched it once without asking me.

I don't want to use the YouTube app, how can I make this stop?

Have a good day!

I hope Mozilla does not add another icon next to the address bar, otherwise it may not be possible to select the address... Do you know a way to edit these icons so they get out of the way? I would't mind disabling translation (not used) or share (accessible via main menu) and the spacing on the icons could use some work too
