Hello Team,

My query is regarding Youtube HD extension in Firefox Android Browser. The browser supports max quality upto 1080p resolution. The query is I cannot watch Youtube video in 1440p , 4k resolution. What's the problem with the extension.

Similarly I use other browser on my phone i.e. Vivaldi browser. On Vivaldi browser I can watch Youtube videos in 1440p , 4k resolution.

How to add speed dials in homepage and URL bar on Firefox Android?

I access some sites instantly like alternative search engines, social media, news sites, messages and others so need them on homepage of browser (also new tab like Chrome otherwise speed dials won't work).

But in Firefox Android and Chromebooks, I can't find a way to have done sites as speed dials like Edge browser, Samsung browser, cococ browser, soul browser, mask browser, kiwi browser, Brave browser, Vivaldi browser, and Opera browsers among others. Only Firefox is light years backward despite being veteran.

Humbly requesting this feature urgently as usability is zero when using Firefox browsers and I have to go back to one of the browsers mentioned in that case.

I'm trying to get Yomichan by FooSoft to install on Nightly for Android (v117.0a1) to no success. Here's what I've tried:

1. 1. Add Yomichan to a custom add-on collection.
2. 2. Go to the add-on manager and tap on install.
3. 3. A little toast that says "Failed to install Yomichan" comes up instantly (see screenshot attached). Nothing is even downloaded.

Notes and information:

• a. The development of Yomichan has ceased and the version on AMO is behind by 3 years (June 4, 2020).
• b. The latest version of Yomichan (October 23, 2022) is only available as an XPI file on the add-on developer's GitHub page. Unfortunately, it is not possible to install add-ons from XPI files on Nightly for Android, so I have no idea if this version would work on Nightly for Android.
• c. Another user (Occupied Octopus) uploaded a rebranded version of Yomichan's latest release in 'note b' called "KiYomi" to AMO. Unfortunately, installation fails on Nightly for Android too, with the same results as in the screenshot after attempting to install it.
• d. Installation of other add-ons (e.g. uBlock Origin, SingleFile) succeeds.

When the "Google Search Fixer" addon is installed and the "Pull to refresh" gesture is enabled, I am not able to freely scroll up on the search results page. After scrolling animation finishes, if I try to scroll up, the browser thinks that I want to refresh the page, therefore the input is sank.

I used to use HTTPS Everywhere, but now this add-on no longer exists in the list of Firefox mobile add-ons. The problem is that in this situation I have no way to uninstall it, because it is not in the Add-ons Manager. So how to uninstall it?

I have been unable to get the Bitwarden Extension to add to Firefox on my Android devices. I have uploaded 4 images (from Google Pixel 3s xl) showing what I have tried.

Can you assist please with information how to get the correct file?

I want to install Video DownloadHelper or Ant video Downloader addons but both of them can't be installed. Is there a reason why some addons can't be installed on Firefox Nightly for Android? If the issue is the addon, how should the developer fix to make it support? Any technical details are welcome

The most recent version of uBlock Origin causes broken page rendering very commonly, which is a massive pain. I read that a user reverted to a previous version to eliminate the issue, but I can't find any way how to.

The addon is offered by mozilla as an .xpl file, but it doesn't seem Android or Firefox have the ability to open this? I tried File Explorer apps that can designate an app to open .xpls with, but Firefox is never in the list. Other browsers just redownload it.

How do I do something so basic as reverting to an earlier version of an add-on? Why must Firefox be this absurd add-on nanny on Android if the tiny listsl of approved apps is going to host apps with browser-breaking bugs?

Hello everyone, there is a feature that Samsung internet uses (and for the most part almost every app on iOS) called "back to top". With the introduction of add-ons I was hoping you could allow us to download an add-on that has similar functionality or Firefox could introduce this feature natively.

I find this feature quite important since you could be knee deep into an article, novel or webtoon and have the need to back to the top of the page (which can be as easy as pressing the home key on PC).

Hopefully there is a solution to this, I didn't think I'd miss it swapping from a browser that has it but I really do.

Is there a way to force "dark mode" for websites on mobile WITHOUT using an extension like Dark Reader?

I am comparing this to coming from Brave, where I am using their "experimental" Night Mode settings (which works great). For the desktop browser, I've gone to Manage Colors and swapped text/background white/black to make most websites appear as if they have a dark mode, but that option doesn't seem to exist on mobile.

I've attached 4 images that show the differences across the two browsers on mobile. Even Google's own Dark Theme doesn't seem accessible through whatever method FireFox uses, so I can't even use that dark theme without an extension at the moment.

If this is not currently possible, I'm hoping it's planned for future implementation. I can't suggest it either since the feature suggestion page appears to be down at the moment (being reworked?).

Hello,

I am trying to install an add-on on my (android) firefox beta by following this blog https://blog.mozilla.org/addons/2022/12/15/new-extensions-available-now-on-firefox-for-android-nightly/ I have submitted my add-on,it has been approved and i downloaded the xpi file. I have created a collection (https://support.mozilla.org/en-US/kb/how-use-collections-addonsmozillaorg) How do i add the xpi file on my collection?

Thanks

In about.config i set javascript.enabled false for most browsing, unless i really need to do otherwise (e.g. ecommerce). If i close the app (menu quit), and restart it, javacript.enabled is reset true. This behaviour is not replicated for other settings i may make, e.g. dom.storage.enabled, or permissions.default.image. Being Android i have no root so no possibility of creating a user.js to override Firefox ignoring my settings. This seems to be a bug. Version is Android Nightly version 121.0a1, 2023-11-05.

Hi,

I'm having trouble installing the Adguard add-on.

I have installed Firefox on my Android phone. I want to add the Adguard add-on to my Firefox browser so I can block YouTube adds.

I have no idea what I'm doing. It's really confusing and frustrating.

Can you please help?

Best wishes, Andrea

I recently downloaded Firefox for Android on my Android 13 device but as I tried opening the menu for the add-on, nothing was found. No supported add-ons were there in the list. I tried doing so from Mozilla add-on the Web page but that didn't help either. What can I do now?

Hello!

Look, i just cannot find a way to install my own small addon for firefox android that i made on my own device. I dont need it to be publicly available. I dont need noone to install it. I just want to install it on my own phone, and that's it, nothing more! That's just a small, few-lines-of-code addon which blocks annoying ads on a certain site me and my wife are using. All i want to install it on our phones. I dont care if it will be firefox nightly release for devs, or anything. If there's any way to install it, like using web-ext, adb, or maybe anything other than that - please let me know. I just spent 50x time more trying to install it on my own phone than actually writing it. Please, i really hope you can help. Thank you in advance!

The Firefox for Android add-ons section (yes, I made sure I was in the 'for Android' add-ons web address, as opposed to the 'desktop add-ons' web address) is saying "You'll need Firefox to use this extension" and not allowing me to install add-ons as the page employs a download firefox link that leads to an "Open" button in the Google Play Store, as I already have Firefox installed. I have tried many different add-ons to test if the issue is isolated to a single add-on and to test if it is an add-on compatibility issue, and it seems to be a consistant issue with all add-ons. Yes my underlying operating system (Android), and the Firefox for Android app are both up-to-date with the latest versions. I have located the Firefox support page labeled "Unable to install add-ons (extensions or themes)" and was able to work through the the list of potential issues and their solutions, to determine that every item on the list was either inapplicable or not the problem/solution. What am I missing?
