Firefox for Android Community Forum

I am trying to switch to Firefox but I'm having a lot of trouble on my Android phone. I have the AdGuard app already installed on my phone and it seems to be the source of the problem. Every link I click on that opens in the browser is blocked when AdGuard is enabled. It's only if I disable AdGuard do the links open.

I have attached a couple screenshots of what I see when I can't open a link. I have no intention of disabling AdGuard just to use Firefox, as I don't have this issue with any other browser I have, including Brave and DuckDuckGo.

Any help would be appreciated.

I want to save my settings in DuckDuckGo's Search Engine, which I think means saving the cookie and site data for it, when I quit the Firefox Android app.

Thank you in advance

I have a LAN Controller which I used to use from more than 7 years. Its small server has a http interface, listening on a specific port, offering the possibility of setting the device and control some other devices through it. This controller is also able to send mail messages in case of some defined inputs, it let me see the rooms temperature, I am/was able to start and close the heating system(s) (powering ON/Off some relays) and some more. I used to have a small shortcut icon on my mobile phone and accessed the above mentioned interface almost daily. Now I am not able do do it, anymore. My mobile phone only opens https URLs. I am able to access the controller interface through Windows and I do not on my mobile phone. When try it, the phone displays: "This site can't provide a secure connection mydomain.....ro sent an invalid response ERR_SSL_PROTOCOL_ERROR" Somebody suggested installing of Mozilla Firefox and get use of its HTTPS-Only Mode facility. I installed the application and HTTPS-Only Mode was Off as default. I tried connecting to the mentioned http URL, but nothing has been solved. I proceeded like here: https://support.mozilla.org/en-US/kb/https-only-mode-firefox-android When I try accessing that http URL it displays: "Secure connection failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem." The single option is a `Try Again` button. Pressing it determines the same return.

Am I doing something wrong? Is it necessary to also make some preliminary settings specifically related to the respective URL? Or something else?

Thanks in advance!

Firefox on mobile keeps on resetting the homepage, I customise the homepage and edit some items like the shortcuts and bookmarks etc, but after a couple of hours it resets back to how it was, as seen in the screenshots attached, it even resets the shortcuts. When I'm in another app and click on a link which will open Firefox, it then shows the get started screen.

I am signed in to Firefox, I have un-installed and reinstalled, wiped data, wiped cache, but the problem keeps on happening, it happens multiple times a day.

Any ideas what I can do to fix this?

How do I turn off swipe to delete a link in collections? If I'm scrolling through the links and my finger a millimeter or two to the left the link slides and is gone with no recover option. Ive lost so many important links this way.

Hello,

I'd like to use the History more fully. As it is now, it's impossible to view the full URL for most sites I visit or the time it was visited. FF's Desktop version has a wonderful History. I'd like to see something similar for my phone. Is that possible?

Thanks.

Currently I'm running Firefox Android 140.0 on Android 15, though this issue has been present for the past two to three years, though it has started to occur more often in the past six months.

When browsing Private Tabs, the browser will regularly close all these tabs on its own, unprompted, and show the New Tab page for Private Tabs. This is visualised by a slide left animation, similar to switching between tabs by swiping across the navigation bar. Sometimes, this also occurs when switching apps, even though Firefox is locked to prevent its background task from being killed. Normal tabs are not refreshed. The “Close Tabs” setting is set to Never. The specific websites accessed do not change anything, as they are different each time.

Steps to reproduce problem:

1. Open several (5-10) Private tabs
2. Browse as normal
3. After a couple of days, whilst browsing, all Private tabs will close themselves. Alternatively, lock the Firefox app in multitasking view, then switch apps for a minute and then return (this tends to happen at random after a couple of days).

I’m developing a web application using Next.js that requires image capture in landscape mode. While the camera feed works perfectly in portrait mode, an issue occurs when switching to landscape mode on Android devices—specifically in Firefox. The camera does not auto-rotate and continues to display in portrait orientation, resulting in abnormal behavior. I’ve attached a screenshot for reference. In the image, the bottle is actually standing straight on the table.

This issue does not occur on other browsers and appears to be Android-specific. The commonly suggested workaround involves rotating the camera feed using CSS and then rotating the captured image accordingly. However, this approach negatively impacts image quality and resolution, which is critical for our use case.

Any insights or support in resolving this would be greatly appreciated.

Facebook has started scrolling down instead of up when typing a comment on the past month or so. Turning off adblock seens to temporarily fix it, but the it starts doing it again and turning ON adblock then seems to fix it and then it goes bad yet again.

Erasing cookies made no difference. This only happens in Android Mobile Firefox, not desktop Firefox. It only started happening in the past month or so.

Chrome does not have this issue at all, but then Chrome can't use Adblock or UBlock Origin either so it's a poor experience either way.
