Firefox Support Forum

Original post: https://support.mozilla.org/en-US/questions/1315759

I wanted to bump this as I never received a satisfactory answer for the reason behavior was changed and it is still something that feels like a UX regression.

Hi lovely People, I try to setup 2FA on accounts.firefox.com with Authy on Android. In Step 1 the code generated from Authy is accepted.

But then, in step 3, when I try to paste in the just in step 2 provided backup activation code, it tells me it's wrong. Am I stupid? I just copied that key from step 2 ... I tried it many times now. Checked if my clipboard is working as expected, tried to delete the spaces in between... I used FF Standard and FF Developer Edition. My Authy is working elsewhere.

Any help? I searched the Forum, found some relating questions, but they never get answered. No one having the same issue?

In my "saved addresses" list under the Privacy and Security section of Firefox Settings, there are two addresses of people that have never used my computer. One formerly went to my school, and the other is a stranger. I can think of no way that they could have had access to my account at any time. Are there any other possible explanations for this?

Somewhere between firefox developer edition 80 and firefox developer edition 94 a bug was introduced that results in firefox showing a huge list of possible public domains for an email address that i'm trying to enter.

Firefox should only show values I've entered previously. Instead it shows garbage such as gmail and yahoo as shown in the picture.

How do I wipe the list that it's using so that it never happens again?

I have seen this in some past versions of FF It usually goes away after a few upgrades

Instead of whatever it's supposed to display, you can see that it shows some random characters.

Annoying. I dont even remember what it's actually supposed to show

It's been almost 6 months since https://input.mozilla.org/en-US/feedback/firefoxdev/88.0/ is down for me (check attachements) So what's happening ?

So I downloaded Firefox and logged in expecting my bookmarks to carry over after I "sync'd" it, however the did not. So I went to my old pc and did the export bookmarks thing and imported it to the new pc.

Now.. I have all my bookmarks and everything appears great. Except whenever I open a link from say my work it opens a Mozilla window that doesn't have my bookmarks. When I try to combine the windows It doesn't let me. I am also scared of losing access to the Mozilla with my bookmarks as I work from home using those. (the desktop shortcut to Mozilla opens the one without all my work)

In the attached screenshot things to note, the bookmark bar available on left isn't there on the right. Additionally in the taskbar (bottom) it shows Mozilla in two distinctly separate icons. When two Mozilla windows are open, they share the same icon on the taskbar, these do not, which leads me to believe I have two incompatible versions existing next to each other.

I use the Windows registry FontSubstitutes (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes) to replace system fonts like Segoe UI with other fonts. It takes a lot of work to get Windows itself to respect these options, to the extent that I have to make it believe Segoe UI isn't present by modifying a different registry location (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts).

However, Firefox does not respect the FontSubstitutes settings. Based on a previous post here, this is something it did prior to Firefox 89, but has stopped doing.

An ideal solution would be a way for Firefox to correctly read my FontSubstitutes settings. An acceptable workaround would be a way to provide Segoe UI for Firefox to use while still preventing its use in other applications. (I know that, for instance, Adobe Photoshop allows users to install fonts to Photoshop itself, bypassing the system fonts folder entirely.)

When I was using version 88.x, Firefox had not crashed for years. Then all of a sudden, Firefox would crash several times a day. I looked and Firefox had updated me to ver 89.0. But I let it ride. Then Firefox about a month ago, Firefox stsrted to crash EVERY DAY. Then one day it crashed EIGHT TIMES IN A ROW and I mean when I hit RESTART, IT WOULD CRASH. I tried to revert to rel 88 but Mozilla WILL NOT ALLOW US TO REVERT BACK TO A PREVIOUS VERSION. When you do, the PROFILE gives you TWO OPTIONS: 'EXIT or CREATE A NEW PROFILE.' Certainly you do not want to CREATE A NEW PROFILE as you will LOSE, your history, add-ons, Bookmarks, EVERYTHING and you see a WHITE Firefox screen with nothing. So I choose EXIT and tried to put up with the CRAPPY ver 89. BUT FIREFOX KEPT CRASHING. TODAY IT CRASHED SIX TIMES IN A ROW......When I checked the VERSION, YOU HAD UPGRADED TO VER 91.0b6 (64-bit) AND IT IS NO BETTER.

WHAT IN THE HECK IS GOING ON. I DO NOT WANT TO LEARN CHROME OR EDGE AS I HAVE USED FIREFOX SINCE VERSION 1.0.

DOES ANYONE KNOW HOW TO GO BACK AND KEEP YOUR OLD PROFILE, FLACKY OR NOT AS THAT IS BETTER THAN 'RESTARTING' FIREFOX ALL THE TIME.

MY VERSION 88 NEVER FAILED.

I used Speedtest by Ookla. When the broad band was installed, the technician did this without a problem. Today when I tried I was taken to an installation page. After I used the SpeedTest, then my main page was gone and instead I have a bar of Firefox selected options. I've tried to find how this is done so I can set it back but I can't find it. Please help.

I am using Firefox Developer Edition Version: 110.0b5 (64-bit) on M1 Mac running Ventura 13.1.

I am building an webapp some XHR triggering in background but it is not necessary to run the application (running fine on other browsers). But on Firefox Developer Edition, It shows a error window with the message and stops loading the application.

Firefox can’t establish a connection to the server at localhost:4000.

localhost:4000 is the failing XHR request domain. I have attached the screenshot.

How to ignore the XHR failing errors just like other browsers?

Hello, I would like to use the search function in the tab again. How can I adjust this? At the moment it is so that when you enter it it appears right above in the link line (see picture). I would like it to be in the search below, directly in the tab. Before version 88 this was possible. Why was it removed?

hallo, ich möchte wieder im Tab die Suchfunktion nutzen. Wie kann ich dies einstellen? Zur Zeit ist es so, daß bei einer Eingabe es gleich oben in der Linkzeile erscheint (siehe Bild) Dabei möchte ich es unten in der Suche, direkt im Tab haben. Vor Version 88 war das möglich. Warum wurde es entfernt?

I recently installed Firefox Developer Edition on a Debian system. I synced my existing profile. There is currently an "import bookmarks" tab displayed that I am unable to delete. I see other existing questions asking and answering this problem, however, I do not have the "customization" option recommended.

I'm coming from Chrome to Firefox, one feature where getting distracted is open multiple bookmarks using CTRL/CMD + clicks

When I bring up Google Maps I put the address in and Firefox shows an error message. This has been happening for a couple of months. See Error Message below.. Google Chrome has NO problem pulling up the address. How can I fix this? Thank you.

A required site I need to use for work has a popup dialog box that never works right in Firefox, the popup dialog shows up as a blank box or doesn't popup at all in Firefox. I must print what is supposed to be there in that dialog box. It's been like this for a couple of years now. I've tried everything imaginable and searched high and low for the fix. I have had this particular site set as an exception to popups blocking, and then I also set it to have all popups unblocked. Still doesn't work either way. I have to use the site in Brave instead, and it's the only way I can get what I need done. I used to love Firefox SO much, I used it exclusively. But it has undergone some unpleasant changes recently, such as hiding my open tabs on my iphone. Because of these issues I find myself using other browsers more and more.

I'm on Firefox Developer Edition 90.0b12 on Windows 10. There is no option to sync addresses in the sync settings, while the option is there for Firefox Beta 90.0b12.
