I've been using Firefox Nightly for Android and Firefox for Android for years without issue. I've left Nightly at build 68.5a1 as it has several features that later bulds removed. I sync across all my mobile devices but NOT with my desktop. When a website requires a newer browser version to run, then I switch to plain Firefox.

Today Nightly would NOT open. It opened and pointed to an offline file. I noticed it was marked by "///". I'm sorry I didn't take a screenshot or note the file.

Reading several posts, I removed Nightly, purged the cash and purged the data. Then I reinstalled Nightly from the apk file I saved. While the install went without a hitch, it will NOT permit me to sign in to synch the data saved in all my other devices. It just spins as this image shows.

I read a post indicating a direct url for sign in and tried it. But it only worked for Firefox and NOT Nightly.

How do I resolve this?

I downloaded, installed the Firefox browser. The browser works but I downloaded it the so I could use all the add on extensions available. The log in button won't load either on mobile or desktop mode on my phone (samsung note10). I wanted to use the Mp3 Downloader ext. specifically & ad blocker for both YouTube & browser. I logged in from a link from search page but it won't stayed logged in on new tab. And I'm back to same problem when I couldn't add extensions. It let's me download file but won't let me open or install extensions says can't open xpi. Files. And could you recommend best youtube mp3 Downloader extensions. Thank you. I've been trying for hours to figure it out.

Before I update my tablet, I wanted to know if my tabs were going to look like they do on my phone or stay the same. I prefer the more "PC" look on my tablet. Screenshot attached for example of them all at the top. If not, what can we do? Thanks!

I have side loaded Firefox (68.11.0) onto my Kindle Fire but am unable to sync my bookmarks. (I was able to log in to my Firefox account only by going to: https://accounts.firefox.com/signin) I cannot log in to Firefox sync from settings. It spins endlessly! There is no option to "SYNC AND SAVE DATA". Your help would be appreciated. Thank you!

¿Existe un Manual de Instrucciones completo y detallado de las opciones "about:config" que permite Firefox en Android?

1. Si existe, ¿dónde está?

2. Si no existe, ¿hay en marcha algún proyecto para su creación?

I can get the sync to work on my laptop but when it comes to the Android box, it just keeps spinning [ blue circle ]. It states on the laptop what devices are syncing but I cannot sign in onto the android because it takes me to no page... just spinnnnnnnning! *sighs* Why can't you guys just leave Firefox alone and quit making all these changes. If anyone has a better browser idea, let me know.
