[edit] I was using my phone to post this question and inadvertently posted it to the android forum. This is a DESKTOP question.

I'm trying to sync my tab groups across my desktop/laptop. I have sync enabled through the settings and I've checked every box, but I don't seem to see an option for syncing tab groups specifically. It syncs all of my bookmarks and active tabs, but the groups seem to be unique to each device. Is this feature available? I might be looking in the wrong spot so if anyone has any insight that would be great! Cheers

When i click fullscreen on a youtube video, it does not go full screen, the video goes to the top of my screen but does not grow and fill the screen. It has been like this for 2+ years

I have a problem. When watching videos on YouTube, especially in 4K, it starts to freeze, and the loading screen stays on indefinitely. The same thing happens when you fast-forward or rewind the video. Switching the video to 1440p or 1080p helps, but over time, even at 1080p, it starts to freeze. but if I switch back to 4K, everything works fine, but only temporarily or until I fast-forward it.

I can provide browser data files. I'll say right away that I've tried a lot of things, and even everything that ChatGPT recommended didn't help. I tried changing the about:config settings related to the video player and codecs.

The only thing that helped was installing a plugin (h264ify by erkserkserks) that disables av1, and in that case the video works fine, BUT only at 1080p, which doesn't suit me, as I would like to watch videos in high quality.

If I disable hardware acceleration so that videos are rendered on the processor, then everything works fine and everything runs smoothly, except that the processor is loaded at 60%. This may be a solution to the problem, but I would like to figure it out and solve it completely, rather than looking for a compromise.

Motherboard: ASRock B850M Pro-A (BIOS date 02/21/2025, DMI BIOS version 3.20) CPU: AMD Ryzen 5 8400F 6-Core Processor RAM: Crucial CP16G60C36U5B (Crucial 2x16 - 32GB) Video card: NVIDIA GeForce MSI RTX 3080 Ventus 3X OC LHR (MS-V389) (Driver version: 32.0.15.7652, Development date: May 14, 2025, DirectX version: 12 (FL 12.1)) Video card driver 576.52, May 19, 2025 The entire system and browser are installed on an M.2 NVMe CT1000P3PSSD8 SSD (Crucial P3 Plus 1TB PCIe 4.0 x4) (there are also other drives) (2 monitors 1440p) Windows 11 Pro If any data is required, I can provide it. All drivers and everything else are installed in the latest version (unless new ones have been released or it has not updated itself). All Visual C++ and Windows components are installed, I don't think there is a problem with them.

The problem only occurs in the Mozilla browser; there are no problems in any other browsers. I also noticed that on some websites where I watch movies, there is a problem with the video. Unlike YouTube, they load normally, but in dynamic scenes, the image breaks up, similar to the image breakup in games when vertical synchronization is turned off. That is, the video is divided into two parts, and one of them lags behind by a fraction of a second. I tried resetting the browser settings, but it didn't help. Everything works fine on my MacBook and in other browsers and devices, so it's not related to the internet.

Please help me figure this out and solve the problem because I've already tried everything, and I don't want to switch to another browser because I've been using Mozilla for over 15 years. Also, if you need any information or a detailed explanation, I can show you or even record a video. Everything worked fine on Windows 10 on the same system, but Windows 11 is not running as smoothly. (To clarify, this is a clean system; I did a complete clean install of Windows 11, although when I upgraded from 10 to 11, everything seemed to work fine).

I would be grateful for any help.

Hi, the latest nightly version crashes everytime on my Pixel 8 Pro. Clearing cache, force stopping and restarting the phone doesn't help.

version 141.0a1 org.mozilla.fenix

I'm not sure what's going on here, but speaking to different people, I hear different stories.

I use FireFox and have PiHole installed on a RasPi. REMOTE ACCESS.

There is a window - to call it - where I can enter any fixed IP addresses.

I can only open it a bit (height wise) but am being told it can open a lot more.

I've tried FireFox and Opera. Both don't allow it to open much more. (So really I don't think it is a Firefox problem)

Anyone have PiHole installed?

The window where you enter addresses.

How "big" can you make i

For the last 2ish months, Firefox will refresh the page if I just place my finger on the screen.

If I put my finger on the screen (not swiping down) the refresh wheel will pop up and refresh the page.

It doesn't happen all the time, maybe once or twice a day, but it happens on every page and causes me to lose stuff like where I was on a page and what I was typing. It doesn't do it when the keyboard is up.

Any suggestion as to what's wrong with it?

Hi. When I go to YouTube.com on the Firefox mobile browser, I cannot for the life of me find my notifications. On the Firefox PC browser, there is a bell icon in the top right of the screen, but not only is it missing in the mobile browser, I cannot find any button or section labeled "notifications." Please advise.

This was the only way I could download Mozilla from F-Droid. Thanks heaps guys/gals. Google has been giving me hell ugh!

I also have the Google Play Store regular issue Firefox browser. Do you recommend I keep both as I'm definitely keeping this fennec issue?

I left a review and was asked to post this here so here goes. Firefox on android is currently the highest user of power on my Google Pixel 8 android phone. From the battery usage data (since last full charge) Firefox has used: Screen time: 2hrs 33mins Background: 5hrs 46mins Totalling 19% battery usage. Even though I turned OFF allow app to run in background!! Before I turned this off, the battery usage was similar. In comparison: WhatsApp -the next highest- is: Screen time: 1hr 42mins Background: 17hrs 52mins Totalling 14% battery usage. With allow app to run in background ON.

The only thing I can think of causing this is the annoying (in my opinion) way that Firefox does not close down all open tabs when I close the app (by hitting the square control button and hitting clear all open apps button) are they still keeping Firefox running in the background as they refresh?

PLEASE add a setting to close all tabs when closing the app. When I close Firefox on my PC and then open it again, I don't get my old tabs, so it must be possible to do on android.

I am using Mozilla in Android.

Collection is a handy tool to open commonly required websites. While selecting a saved website to open, I have unknowingly selected X and my collection got deleted.

How to recover them. There can be a better way.

Can there be an Undo option. Avoid both Opening or deleting option in one line. Separate screen for Management of Collection.

Thanks.

some pages while browsing would refresh upon touch input. usually it happens only once. but in one website it kept refreshing as I tried to click anything. only way to stop it is to touch and hold to see if the refresh symbol appears and if it does, I have to slide the finger up, before releasing, so as to cancell the refresh.

FX mobile version 139.0.4, Galaxy A14 5G

If I pause for longer than 4 seconds while typing a YouTube comment/reply the keypad disappears and I have to tap in the text box to make the keypad reappear.

How do I make the keypad remain unconditionally visible while typing YouTube comments/replies?

Hi Mozilla support,

I have installed Firefox and Facebook Lite on my Android 13. When i try to open a link to Facebook.com that is coming from somewhere else than Facebook Lite it is taking me to Firefox where it asks me to open in Facebook and then takes me to the Facebook app in the App Store, ignoring that i have Facebook Lite. Any solution to this?

I suspect I am PH#€%ed. Am I eligible for a miracle?

S10+ 139.0.4 NOT set up to sync | see attached for specs

In the bookmarks toolbar, I have many folders. I had one named Reference and one named Research. A few weeks ago after a big update my bookmarks had somehow nested multiple copies nested weirdly.

I messaged for help through the Garg app store, and a developer said to please file a ticket with support. I MEANT to do it, but time got away, and I'd already cut the sync and done a lot of cleanup.

I'd removed this phone from sync (no SIM, no cellular connection for the last year, but I use it on Wifi—I carry it around a lot for note-taking when I get brain dumps from people).

I discovered two Reference folders— one in the Toolbar and one in Bookmarks. I moved the one in Bookmarks to the Toolbar, and then moved everything in it into the other Reference folder, which had more, figuring I'd go through and delete the dupes at some point.

I then deleted the empty Reference folder and got the question, "Are you sure you want to delete the selected items [you IDtenT]?"

I confidently clicked yes, not realising my stupid fat finger had clicked on the RESEARCH folder to delete.

I may be able to find some of it to sync or sneaker net from elsewhere but there were swathes of unique addresses in that damn folder. I tried to search bookmarks for the folder and then for any folder. I tried to search "Internal Storage" for any whisper, and Apps which I hardly have any read access to in the file tree without success.

I read the readme called Manage Bookmark Folders in Firefox, plus a couple of hours of additional readme reading and flailing... but I cannot find the answer to a short list of pertinent questions.

1. How does one search/find a bookmark FOLDER, a regular one, which some ahole hasn't deleted?

2. Don't the help articles mention an UNDO option when deleting individual tabs and bookmarks? Sorry, bit of a swivet, but is there an undo for folders? I found no such offering mentioned when deleting an entire folder. I'm assuming no, but... (this might be a good place to mention (while I'm headbanging my desk) that some *other* browsers contain a numeric in their deletion warning, rather than a ubiquitous "these items", whether it's an empty folder or full), hope will spring. Biat£#.

3. Third and final— is there any way for someone without access to costly forensic software to recover this data?

A lifetime of backup, backup, redundant backups is mocking me, so please don't laugh at my self-induced misery. If there's no remedy, give it to me straight.

TIA, Alex
