After upgrading firefox to the latest version 110.0.1 few users are getting a prompt that firefox version is old and they need to create new profile.

"Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox."

I have tried: -uninstalling/reinstalling newest version of Firefox -using run, firefox -p to open the profile -creating a new profile altogether -setting my default profile

Please let me know if there is something else we can try or a fix out there I haven't found

Whenever I try to launch Firefox on my windows 11 pc it always crashes even when I true the official fixes and install it through different means it always crashes on startup

Ever since about 2 Firefox updates ago, I cannot share articles to Twitter using Firefox. When I share, the Tweet dialogue box pops up showing the article, but the sidebar on the right side of the box (the one needed to scroll down the message to the Tweet button) is greyed out and no amount of clicking, trying to drag, etc., will get it going.

I cannot replicate this problem on Edge, as that browser works seamlessly when sharing articles to Twitter and I am able to scroll down to the Tweet button with no problem. Same with Chrome, I have no problem there, either.

This seems to be a Firefox problem and I cannot for the life of me figure it out. I have not changed any of my Firefox settings. I've disabled all of my extensions and it still doesn't work. I find myself using other browsers more and more as with each Firefox update there seems to be more technical bugs that aren't being fixed.

But I use Twitter often, so this is a significant problem for me. Any reasonable suggestions?

After my Webmail interface was updated the webmail buttons no longer function at all. I cleared the browser cache, history, etc. and restarted the browser. But the problem persists. The webmail interface does work in Chrome. Any ideas how to fix this? Thanks!

I have 2 financial websites that I am unable to use Firefox on and I have to use Chrome. The site are Fidelity Financial and Jackson National. When logged into the website I must select certain links to see the information I am seeking. When selected, Firefox does nothing, it stays on the page with the link I selected. I do not have pop-ups blocked and cannot find the reason for the fault.

I'm not sure whether it happens at current version of Firefox or already happened previously, but if you close your Firefox main window without closing your Private window first, all your session tabs will be lost when we launch Firefox again. Is there any way to recover my previous tabs?

Hello, Last time I attempted to sync Firefox on my existing PC and Laptop, I ended up with only what was on the 'minor' of the 2 devices. How do I do the initial sync to ensure that the settings on my PC, my 'primary' computer, are moved to the Laptop (the secondary computer) and not the other way around? Thanks Chris

I have cleared my cache and cookies, I also checked my passwords and logins and nothing was in there. I closed the browser and reopen it to go on the same website. I tried to sign in and my information is still there as an autofill. How can I wipe everything?

Can anyone tell me how I go about removing this malware please? It suddenly appeared whilst using Firefox in the last few days. I'm not very tech savvy so simple instructions would be great.

"Open previous windows and tabs on startup" doesn't seem to work for me - I check off the right box in Settings. (see attached file) but it doesn't work. I use Firefox as a dedicated app for one project, so would like it to open right at the four pages I always use.

Odd, because this USED to work, but has stopped doing so in the last week.

Laptop using Windows 11 64.

I downloaded the newest version, also signed in and out, but no help.

Thanks.

One of the best features of Firefox over the years has always been the ability to add new tool bars. This was brilliant for storing your Add-on icons.

Is this gone now? If not, how do I go about adding new toolbars. Running Firefox MSIX-1.0. 111.0.1 64-bit. Windows MSIX package.

How do I prevent firefox from redirecting to HTTPS when it can't find the HTTP website I typed into the address bar?

Background (please read) I run a website for my team at work off my local machine. It's just http, because it's local, and I don't need any fancy encryption schemes. I have no domain for it ... me and my users just type the local IP of my machine. Like this: http://10.111.111.11/myapp/login.php

To work from home, I set up a VPN tunnel thru my workplace firewall so I can hit the webserver on my local machine. If I forget to start the VPN tunnel on my remote machine and then try going to my website, I get an error message in firefox:

   Unable to connect
   An error occurred during a connection to 10.111.111.11.
   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

After receiving this message, Firefox changes the address in the address bar from what I typed to the same thing, only with "https" instead of "http". This drives me insane. How do I force Firefox to preserve what I typed in the address bar EXACTLY as I typed it?

Hi I use Firefox on 2 mac and 1 IoS device. The passwords or saved logins don't seem to sync across devices, even though they are all logged in via my account. Kindly advise.

I cleared my cache and cookies, had to restart my pc - macbook pro. After opening Firefox, I was signed out. I had to ask for password reset and once signed in, it looks like all my bookmarks are gone!

How do I recover them pls? I did not saved them anywhere or made a copy of those.
