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?

Up until 2 or 3 weeks ago, I was able to log in. Now I Get "Access Denied". I've tried granting all permissions, cancelling vpn. I can log in if I use Chrome. FRUSTRATING. I like Firefox...

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?

Is there a way to stop this tab (https://www.bing.com/new#examples) opening when I open up Firefox? I believe it is to do with when an update occurs. I don't use Bing, never have and never will, it's frustrating. I have disabled all settings related to Bing that I can find in the settings. Am I missing something? I just want to start where I left off, not be bombarded with Bing at every turn (Microsoft takes care of that for me)

Ref Firefox Ver 84.0.1 OS > Win 7-64 Dear Firefox Support,

 I have already contacted MS support about the subject issue and they were no help.

I am trying to find out what is causing the issue and how to get rid of it.

 I can't be sure but it may be caused by a Microsoft "START" App.  The issue appeared

to begin about two weeks ago, so it's obviously caused by something new, which may be Microsoft related. Below is Dropbox link to a screen capture of the issue.

 Any tips for ridding my PC / Firefox browser of the issue will be greatly appreciated.
 And thank you for the superb browser.

Best regards, Ken Boardman > elsmoko@cox.net

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.

I usually have 10 or so Firefox Windows open - each with 5-10 tabs. Everything should be running in the same instance of Firefox as each Window was opened with the "New WIndow" command in the "File" dropdown menu. When I let MS WIndows update run I usually have only 2-4 windows restored. When only Firefox updates, all windows are properly restored.

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.
