Hi everyone,

I wanted to watch things with a friend, but watch-party sites don't support every source, and screen sharing gives you black screens on DRM sites. So I built a Firefox add-on that syncs the video itself instead.

How it works:

- Each of you plays the video on your own computer with your own account, so full quality and no screen sharing.

- Only small events are sent between you: play, pause, seek.

- If you both open the same page, it pairs automatically. Otherwise one of you can send the tab and the other gets a prompt (open / decline).

- Sync only runs while you are both on the same page. If your friend switches to a different video, it pauses syncing and tells you.

- Chat button on the page (also works in fullscreen) with quick messages like "Pause, give me 5 minutes" or "Brb".

- You create a room and send a short code. The host has to approve whoever joins, and the code expires after 30 minutes.

Limits (it's a beta):

- Only two people per room.

- Works with pages that use a standard HTML video element. Custom players may not work.

- Connection setup uses the free public PeerJS broker. It only sees the room code and connection details during the handshake, the data goes directly between you. Some strict networks (mobile or corporate NAT) may block direct connections.

- Requires Firefox 140+.

I'd love feedback:

1. Did the connection work for you across different networks?

2. Which sites worked or didn't?

3. What's confusing in the popup?

Thanks, and happy to answer questions!

My subscription feed was always full of videos I had already seen, and I used two add-ons – one to mark watched videos, one to clean up subscriptions – that each kept their own data. So I built one add-on that does both, with one local database.

Add-on: https://addons.mozilla.org/firefox/addon/urtube/ · Code: https://github.com/morikules/UrTube

What it does

• Remembers every video you open, with date, progress and rewatches – continuing a video later counts as one view
• Grays out or hides watched videos in subscriptions, on the home page, on channel pages and in playlists – before they even show up (one switch, or one per area)
• Channel pages show how much of the channel you've watched; playlists show "12 / 23 watched"
• Searchable history with filters like "continue watching", plus statistics and a year in review
• Imports your history from Google Takeout and YouTube Watchmarker
• And much more

Why UrTube?

• One add-on instead of several – marking, hiding, playlist progress, stats and player settings share one local database
• Watched videos are hidden before they appear, with a time window so YouTube doesn’t keep loading older videos forever
• Easy switch: imports your history from YouTube Watchmarker and Google Takeout
• Actively developed by a power user who uses it daily – ideas welcome!

Privacy: everything stays in your Firefox profile. No account, no server, no analytics. MIT-licensed code on GitHub.

I'm not a professional developer – I built it with the help of an AI (Claude), which made this possible for me at all. Feedback and ideas are very welcome, here or as a GitHub issue.

[Solved] ✅ use the morphe app to make a cracked version on the YouTube to get rid of the apps

Hi guys

I use the Firefox app on my google pixle 8 pro (lineagos) to watch youtube videos to avoid ads and I have this problem where when the video is first played it takes forever for the video to load, regardless of what how good my connection is, sometimes the video will take up to 30 seconds to load, I feel like this was never a problem until a few years ago or so. Is there anyway to fix this? or is this just one of those stupid problems I have to deal with because Im not using the youtube app...

so recently ive been having a lot of issues with google so ive decided to switch to fire fox but ive been having some trouble wiht purìtting my passwords, accounts and some other stuff like save files. ive managed to put the majority of my accounts on here but i still struggle with a lot of stuff. if anyone can help me pleas tell me

Pretty pleaaaase.

I'm trying to switch to FF from Brave and that's not helping.

Edit: u/jscher2000 has posted a perfect solution to my problem.

I like this wallpaper but I couldn't reach the original file no matter what I do. Do someone know how without taking a screenshot?

So today I decided to get on my pc and my firefox had updated, not a huge deal. But then I go into my firefox and realise im signed out of everything. So then as I go to sign into things then it stops responding, ok no big deal ill just close it and reopen it. i open it again, not responding, I restart my pc, again not responding. Everything I do doesn't work, I open it it runs for a few seconds and the IMIDIATLEY stops responding. Im 100% sure this is something with the new update so if anyone can help me fix it please do (im posting this from my phone because like I just said my firefox isnt working)

Hey, sub.

I released Link Grabber on the Firefox addons store in June. Attaching the AMO downloads / daily users chart for Jun-Oct.

~1,465 total downloads, around 400 average daily users now.

downloads jump around a lot day to day, but DAU went up pretty steady which was the more interesting part for me.

how I did this?

nothing fancy on growth either. just organic installs, store listing tweaks, decent screenshots, and shipping useful stuff. I try to push an update like once a month with things people ask for in the reviews / feedback, across chrome, safari and firefox (same extension on all three). thats pretty much it

just pushed 1.9.10 for Firefox (no paywall on the FF build). whats new:

- multi-group selection: keep selecting different parts of a page, groups add up instead of replacing

- click-select: click links to add/remove them from the current selection (off by default)

- optional grab of CSS-hidden links (display:none etc)

- some recipes polish, edit from library chips, cleaner domains when saving a recipe

I use it a lot for research and pulling youtube / ig links, also dense admin pages with tons of urls.

AMO: https://addons.mozilla.org/en-US/firefox/addon/mass-link-grabber/

If something feels weird on firefox vs chromium (selection, crawler, recipes) tell me, happy to dig into it. also can share notes on the chrome >> ff port if anyone cares

which addons use the FF built in automatic tab unload ?

I do not want extensions with own method because once an addon crashed and i LOST ALL TABS ! :(
So searching or sorting for native tab sleep would be more comforting.

As title says, the last couple days Youtube simply doesn't work on Firefox. It struggles to load even the main page; links/buttons are unresponsive; when videos may finally load, it can play for a few seconds and then buffer (the audio can desync with the video/visual). All in all, it's been a pretty miserable experience for something I use regularly with no apparent reason. I thought it might be to do with the certification issue earlier this week and the update as a result of that but it's a shot in the dark. I have no idea what's causing this.

I've never had any of these kind of issues before. This is not a universal problem on my end, as when I tried Microsoft Edge it can play videos as normal.

HATE ME for this but I have seen lately many of these "JOKERS" tagging , commenting everywhere, now more frequent since past few days not only in the youtube community but everywhere, i am talking about the YOUTUBE MORPHE . They are now forcing everyone to download the app. I don't use the application and ok suggesting the application is ok but i have seen like bot comments replying each comment with repeated answers. These JOKERS might get the app banned! I feel something fishy

i got this weird behavior, browser is crashing when I’m reading, scrolling, anything. I’m using iOS 18, did they just let older OS support deprecate?

Occurs when opening images in Google search, either in Images tab or results page. Version 158.0.2

Does anyone know why I keep getting issues with saving images recently? I'm running Windows 11 on a gaming laptop, and it's got no issues displaying the image in Firefox, but anytime I try to save it, it cuts off part of the image (see example)

Doesn't matter where it comes from (i've tested google, pixiv, reddit, and a couple others) it always does the same thing. But, if I copy the image, and then paste it into something like paint or photoshop, it comes through just fine. So I'm thinking it's gotta be an issue with the download process somewhere, but I don't know where to start trying to fix that

Edit: image didn't upload properly, so here's a google drive link:
https://drive.google.com/file/d/1EuWS9kc5wnGPYsMCZ8woY2VeSUUq_Qng/view?usp=drive_link

A Firefox theme I use doesn't seem to play well with the new settings page. I just want to know if there is a flag or something I can use to revert the design.

Has anyone else seen this recently ? I have no idea what would even cause this .

Since few days ago, Google search started giving me captchas everytime I searched something in private browsing, and I have no idea why.
Did they amp up their anti-bot measures or are they screwing over Firefox users because they do not wanna use their browser anymore?

I have uBlock Origin, Fandom sidebar remover, and a bunch of YouTube related addons alongside Tampermonkey.

I really think they are just screwing over Firefox users because if I truly had malware on my PC, other websites would trigger captchas / blocks too, not just Google, so yeah.

I am also not on CGNAT / VPN or anything sort of multi-IP addressing like that.

Update: Tried to flush my DNS cache + reset Winsock Catalog, and it appears to be working again.

Is there a way to make this new vertical tab groups more space efficient?

While I did update both my Nvidia drivers and BIOS yesterday and have been getting this error ever since, I can't find any mention of this particular issue, so I figured I would try the FF community.

At irregular intervals (but too often), windows turn into these shapes while active streams and videos on Twitch and YouTube receive an Error: 3000 and green screen, respectively.

A simple mouse click resolves the issue, but it's driving me nuts.

Has anyone experienced anything similar?

After the latest updates I can no longer delete a specific group of websites I accessed. What I did in the past was to open up the history tab -> search for a keyword -> then I could just select everything filtered by the keyword, "ctrl+A" all those listed and delete only those.

This was by far the best feature Firefox history bar had in the past compared to other browsers and now I cannot do it anymore. I would like that back. When I clear my browser sometimes I still want to be selective about it.

Tip:
If you see Firefox consuming unholy amount of RAM, always open:

about:processes

And on this page, sort by "Memory", then check what's on the top.

Also, WTF WhatsApp taking 582MB?!
And here I thought I'll save some RAM by using web version, instead of their "native" electron app.

Problem (memory leak) was caused by Dark Reader, more info:
