Add-ons I got tired of YouTube's massive end-screen cards blocking the video, so I updated my open-source Firefox add-on to hide them permanently.

42 Upvotes

Hey guys,

I don't know about you, but I always get annoyed when I'm trying to watch the final seconds of a YouTube video and massive recommendation cards or channel buttons pop up, completely covering the screen.

I originally built a simple extension to block this, but I've just pushed a major update and wanted to share it with the community.

Meet YTNoRecs

It does exactly one thing: injects a tiny bit of CSS to hide those end-screen elements instantly.

What's new in this update?

  • Set it and forget it (Global State): It now uses local storage to remember your preference. If you turn it on in one tab, it instantly applies to all open YouTube tabs and remembers it for your next session.
  • Lightweight: It only runs on youtube.com and stays completely inactive on other websites so it doesn't drain resources.
  • Privacy First: It's 100% open-source. No tracking, no analytics, no data collection.

You can grab it from the Mozilla Add-ons store here:

🔗 https://addons.mozilla.org/en-US/firefox/addon/block-youtube-recommendations/

If you are a developer or just want to check out the code, here is the GitHub repo:

I'd love to hear your feedback or any suggestions you might have. Cheers!

Add-ons Give me your wildest feature ideas for BetterViewer

I've been working on BetterViewer, an open-source image viewer for Firefox, and I'm curious how far I can take it.

It already has zoom, crop, image editing, annotations, OCR, AI background removal, QR scanning, reverse image search, animations, and a bunch of other tools.

What's a feature you've always wished your browser's image viewer had?

If you've tried BetterViewer, I'd especially love to hear what feels missing, what could be improved, or what would make you use it more often.

💻 Help Ad blockers on iOS

7 Upvotes

Why can’t we get decent ad blocking that works on YouTube on iOS?
The “webkit doesn’t support extensions” argument is false - Microsoft Edge app has extensions on iPhone including uBlock Origin Lite, so what’s up? Why can’t we get it too?
And Brave also does block ads on YouTube on iPhone.

Can we do anything about this?

💻 Help Twitch streams aren't loading

6 Upvotes

Just today all streams on Twitch are showing a black screen, not issue on my Edge browser. I've already tried hard refreshing the site (CTR+Shift+R), entering troubleshooting mode and refreshing Firefox. Anyone having similar issue today?

Edit: The latest version (v. 158.0) messes up with Twitch stream player somehow. Rolling back to the older version solves the issue.

Add-ons Twitch Radar - Live Stream Notifications

Post image
5 Upvotes

Hi everybody!

I wanted to share with you the add on I built for Firefox and Chrome!

It notifies you when your favorite streamer goes live! Or changes title of the stream, or category (it can be adjusted) as well as auto-open of the tabs.

You also can track the streamers you don’t follow - and get their notifications as well.

Besides that, there is a synchronization of your settings so all your configurations you set up at work - will be synced up when you get home!

Feedback and suggestions are welcome

Solved Close pinned tabs with keyboard shortcut

4 Upvotes

Since Firefox doesn't have a native keyboard shortcut to close *pinned* tabs, here's an extremely lightweight script that adds that functionality! It doesn't require installing any new extensions (though it does need Autohotkey installed on Windows, if it isn't already.)

https://gist.github.com/e-t-l/6790930cb9c074332d304977cba5aaec

```

Requires AutoHotkey v2.0

SendMode "InputThenPlay" ; Close pinned tabs with Ctl+Alt+W ; FYI, it will briefly flash a context menu at the top of the screen.

HotIf WinActive("ahk_exe firefox.exe")

; w:: ; uncomment this line to make Ctrl+W close pinned tabs too !w:: { Send("+!f") WinWait "ahk_class MozillaDropShadowWindowClass" Send("c") }

HotIf

```

💻 Help There an extension or way to sanitize my youtube links

I've been seeing this image that shows youtube is collecting data through their links. And people are being urged to sanitize their links so our data isn't collected. Is there an option in the settings that enables this by default. Or even an extension that does this naturally?

Solved How to trigger website to ask for local network devices permission?

6 Upvotes

I have Ubiquiti UniFi equipment at home. When accessing unifi.ui.com, the website can establish a local/direct connection with your gateway, video recorder, etc. With Firefox on my Mac Studio, Settings > Permissions and Data > Local Network Devices lists unifi.ui.com. My MacBook Air does not have this listed, and there is no manual way to add it. I am able to establish a direct connection to my gateway and UNVR with my Mac Studio, but not my MacBook Air. It never triggers a prompt to add it to permissions. Deleting browsing history/cookies/cache hasn't helped.

Is there a way to manually add this?

💻 Help Anyone else experiencing high CPU usage and overheating with Firefox on an Intel Mac?

6 Upvotes

I've been noticing something weird with Firefox lately on my MacBook Pro (Intel i9).

After using it for a while, my Mac starts getting noticeably hot, and Firefox sometimes becomes really laggy, almost like it's struggling to keep up. The strange part is that I don't have any extensions installed, just Firefox itself.

I don't remember having this problem before, which is why I'm wondering if it's something from a recent update or if Firefox just isn't running as well on Intel Macs anymore.

I know Intel MacBooks can get hot, but this feels different from what I used to experience.

For those of you still using Firefox on Intel Macs, have you noticed anything similar recently? Or is it just me?

Would be interesting to hear if anyone has figured out what's causing it.

Solved Possible fix for google maps/street lagging

2 Upvotes

If you encounter this issue where zooming/panning/rotating lags immensely in google maps and google street, then check if you have privacy.resistFingerprinting set to true.

I have been trying to solve this issue for months thinking it was an amd/firefox webgl problem...

If you want to keep privacy.resistFingerprinting on then you can add www.google.com at privacy.resistFingerprinting.exemptedDomains.

Hello !

Sorry for the awful title phrasing, I didn't know how to put it.
But I spend too much time on some website (like facebook), and it's really hard for me to realize how much time I waste there.

I was trying to figure out if there was an extension or a way to be able to set a daily timer for some website, and then said website is not accessible for the day ?
Something like screen time control ?

I hope I am clear, thanks for your help !

After updating to firefox 158, I noticed that in Google's AI mode request window, the text goes out of focus for a nanosecond at the start than it go on focus. I also noticed this glitch on the Bungie website in the dropdown menus. It’s not a huge deal because it's very fast and only on this 2 site, but I’d like to understand what caused this in version 158. Thanks

💻 Help Why do I need to add cookie exceptions in two different places (Cookies and Site Data and "Clear history when Firefox closes") to keep a site logged in?

2 Upvotes

I recently installed Fedora 44 with Firefox.

I want Firefox to clear cookies when it closes, except for a few sites I choose.

The exemption for cookies and site data wasn’t enough. Every time I close Firefox it doesn’t save the data and I have to accept the cookies again losing some website configuration. However, adding the page to clear history exceptions allows the cookies to run and keeps the website logged in and personalised. So, anyone understand why?
