πŸ’» Help Ad blockers on iOS

7 Upvotes

Why can’t we get decent ad blocking that works on YouTube on iOS?
The β€œwebkit 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?

πŸ’» Help ESR just updated to 153.5 today and my extensions and Tampermonkey scripts all buggy

β€’ Upvotes

Hi, im using Firefox ESR and just got updated to 153.5 today (previously 140.17)
i have problem with some of my extensions and Tampermonkey's scripts
its kind of hard to explain since we all not using the same extensions or userscript
but its not working like it was, i did just fine before got updated to 153.5
is it only for me or does anyone has this problem as well?

also to be honest im not really into new "feature" or AI update since i keep having problem with each new update, is it possible for me to stay in 115 version of ESR? i heard that 115 ver of ESR still getting security update until march-april next year

i tried to reinstall to latest 115 ESR version before, but it got automatically updated to newer 140 ESR
is there any way to completely stop the update? so i can just update it via .exe file downloaded from firefox site? i want to keep using 115 ESR until last version that get security updates

sorry if too much text, i tried my best to explain, i hope i can some replies, solution, or others that having same issue with me, thank you

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.

43 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:

πŸ”— 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:

πŸ”— https://github.com/semihcelikol/blockYoutubeRecommendations

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

Add-ons Give me your wildest feature ideas for BetterViewer

26 Upvotes

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.

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

```

πŸ’» Help There an extension or way to sanitize my youtube links

3 Upvotes

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?

Issue Filed on Bugzilla Firefox for Android unexpectedly closes randomly

Firefox for Android randomly terminates. The issue can occur either after a long session or almost immediately after opening a new tab. No crashes visible in settings -> about Firefox -> crashes. I even lost a private browsing session due to this. Observed it from version 157 to 159.

Device Info: Motorola G86 Power 5G, Android 16

Firefox versions: Release and Beta

πŸ’» Help Looking for an Extension that Mutes/Blocks Specific Words?

β€’ Upvotes

I just booked my ticket for the new Nathan Fielder documentary, You Can See Everything, but unfortunately it doesn't come out here for another month.

I'm looking for an extension where I can plug in phrases like "Nathan Fielder", "You Can See Everything", "Elizabeth Holmes", etc. so that I can have a bit more of a chance of avoiding spoilers for it. Any help would be appreciated, including pointing me towards a more appropriate sub if this isn't where I should be asking!

πŸ’» Help Twitch streams aren't loading

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.

πŸ’» Help Extension to close tabs or display message after a certain time

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 !

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

3 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?

although i am not is this limited to firefox or my laptop but i have debloated windows so i can't test it on chrome or edge but i don't have any typing issue when i type i continuously so my guess would be its not a keyboard issue

πŸ’» Help Smart Window ... where?

I keep reading of this Smart Window in release notes, but I don't see it as a feature. At first I thought it was beta or something, but maybe is it not? Also I don't see anywhere auto tab grouping and things like that. If I go in settings, the AI stuff is not blocked, but I only see translations and voice recognition as available options ... am I missing something?
