Firefox for Android Support Forum

I have two Zebra TC8000 hand scanners running Android OS 5.1.1 that I've reset to factory defaults. I need to download and install Firefox but each installation attempt fails either at the download or at installation. No real detail is given as to what the issue is. I just get a message "Queueing" or "X App not installed."

I've attempted to install our regular APK that has historically worked fine. The download location is... https://download.moziilla.org/?product=fennec-latest&os=android&lang=multi The APK from this site no long downloads. The download status just shows "QUEUEING" for 5-7 minutes then fails.

I switched to browsing directly to the Mozilla FTP page and attempted to download several versions of Firefox for Android. The latest version 125.0 at... https://ftp.mozilla.org/pub/fenix/releases/125.0/android/ Here, I tried installing each of the three APKs offered here and receive the message "X App not installed" with each attempt. I am, at least, able to successfully download the APK and launch the install but I can't get the install to work.

Any clue on what could be wrong?

When i try and accept an e-transfer using Firefox, I'm getting an error message "Application error: a client-side exception has occurred (see the browser console for more information". I've always been able to accept e-tranfers in the past.

We cannot get a google account because our landline neither sends nor receives text messages. We are in process of setting up and testing a cell phone, and would like to load Firefox for Android as the browser. We cannot download from google play because google demands to send a text-message "verification" code. We note, thankfully, that Mozilla does not (stupidly) do likewise to set up a Firefox account.

I'm making this thread since the previous one was closed and provided no real solution, yet the result shows on the very top of Google. So I like to provide helpful information to others in my answer below.

In the recent update, there is a new feature which allowed people to view pdf directly in the browser rather than downloading it. Ever since this was implemented, I am not able to download any pdf, instead it keeps opening up the pdf in another tab which is not what I'm trying to do. Is there a way to fix this?

Can't move Collections from my old phone to my new phone I have pressed sync BTW it still doesn't appear on the new phone. The photo is the two Collections containing 100 web addresses each on my old phone.

Starting about a week ago, every time I try to download a PDF file, it opens in a new tab instead of actually downloading. I have to copy the link and paste it into the Google Chrome app to make it download properly. How do I fix this?

I try using the pair feature but each time I scan, I get a page showing "Did you use the system camera? You must pair from within the Firefox app" Even though I did pair from the Firefox app. I have tried multiple times, always the same issue.

Hello, I recently got a new Android phone. On my previous Android phone I used Firefox without creating an account and saved hundreds of bookmarks. I would like to move those bookmarks to Firefox on my new phone. Please tell me how to do this. Thank you!

Hi. I downloaded the latest issue of Firefox (104.0.1) to my mobile phone and since then I have been unable to connect to the internet via 4/5G - but it is OK using wifi. This is highly annoying when I need to connect whilst out and about. Weirdly, the calculator on the phone and Samsung Notes have also disappeared and I am unable to download from the Play Store! All the usual things like rebooting, cleaning caches etc do not work. Is it possible to roll back to an earlier version? Any ideas would be useful, given the lack of phone contact available, thanks

Android 13 / Firefox 111.1.0

Since a short while it seems that Firefox for Android opens pdf-files directly in the browser instead of offering the download option (as it used to be). My Samsung Tab6 Light shows the pdf in compressed fonts, thus it is mostly unreadable. How can I download the pdf instead of viewing it? Or: How can I download the pdf to save it on my device? If I tap the opened pdf a function 'Share' is offered, but then when I try to share via Email nothing is shared!??

Thank you kindly for any support in this. Ueli (Switzerland)

Due to the Firewall of our government, we Chinese couldn't download Firefox Android on Google Play Store without violating the law. And, neither Github nor F-droid provides the service for users in China to download the app directly.

How could we download it?

I recently made the (apparently) foolish decision to allow Firefox to upgrade using the Play store App. This is on a Galaxy S8 running Android 9. Firefox 109.2.0 was installed and upon opening the App, all of my user data was gone. No tabs, bookmarks, saved passwords or other settings were available.

This is unacceptable. There appears to be no way to recover the lost information, but I am opening this case to determine if there is a recovery strategy. Of course, I don't really want to run version 109.2.0 and will revert back to something that works without losing data as soon as the missing data is recovered.

I'm not sure why the Firefox Devs seem to think that user data is a disposable and unimportant item, but I would encourage a full review of their processes to determine why they have failed so badly.

In the meantime, if anyone has a method that might be used to recover the old profile data, that would be very helpful.

Some notes: 1) No, I don't use Sync (or whatever they are calling it today) because it is a security risk in my view to have any third party including Mozilla know my bookmarks. 2) about:profiles does not work. 3) I'm not sure what version was installed earlier, but AdBlock Plus was working fine, so it may have been a year or more since my last update.

Thanks in advance for any help you can provide.
