I upgraded my Dell PC to Windows 11 yesterday via Windows Update, since support for Windows 10 is ending. Now Firefox crashes often when I close the browser. Everything works fine while I'm using Firefox, it's only when I close the browser that sometime later I will get a crash message on my desktop. I have tried uninstalling Firefox and reinstalling it, and the problem persists. From what I can tell, there's some process which is ongoing after the browser is closed, which isn't terminating properly and that's why it's crashing. I have submitted several crash reports, but don't know how to post them here.[bp-2e2d8f06-4c87-43a6-8b32-b0f5a0251006]

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

I think that i get some virus in my computer, in the last two days some of my accounts were accessed by an unusual way.

I´d like to know if the problem was my passwords kept on firefox, all the apps that were hacked had the password saved on the firefox manager.

There's a way to know if my passwords on the Firefox were stolen ?

Yesterday I upgraded my PC from Windows 10 to 11. Today I discovered my Local Folders are not visible. Searching tells me the messages still exist, but TB does not show the folders. I did the same upgrade a month ago on a laptop (Windows 10 Pro to 11), no problems. I didn't externally back up the messages as I am a dinosaur and don't know how, but at least they are still on the hard drive. Thousands of them though so I need the local folders back. Tried all the fixes I can find on the Community Forum, without success. Can anyone help please? Bob

I just had to sign in to this forum although I had never logged out. I am using Firefox 143.0.3 (64-bit) on Linux Mint 22.2. It is not the first time I am having to login again in one-by-one the sites I visit. And before anything else, I have not changed any of my privacy settings and no new profile has been created due corruption of my default one. It is not the first time this happens lately. Any chance with the Firefox update? I think I installed one quite recently.

TB not showing all local folders after new TB installation on Win 11 and migration of profile from old Win 10 computer

I used TB for many years on several computers. Last week, I had to reinstall TB on a Win 11 computer, and tried to migrate my TB profile from the Win 10 computer. However, this is an ongoing problem. After several attempts, I have a TB profile on the Win 11 computer that seems to look OK. However, when I open TB, not all the local folders appear in the TB Local folders menu. I read several discussions and guides from other TB users, and tried the suggested fixes. They did not solve the problem. The Local Folders exist in the profile in the Mail folder. When I open the Local Folders, I can see all my local folders that were copied from the TB profile on the Win 10 computers. These include .mozmsgs and .sbd folders. When scrolling down in the Local Folders, after the .mozmsgs and .sbd folders, I can see pairs of folder names w/o extensions (the open with notepad and contain text) and files with the same names but with .msf extensions.

So, theoretically, all the local folders should show up when opening TB. But they don't.

At this stage, I don't know what to do, and I would appreciate your help.

Thank you.

Ted

Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

The new machine is not quick to send a post to junk or trash. I see a message about downloading it before I see it move. Going over settings comparing both, old machine was set to a Pop mail server. The remote helper changed that oh New one to IMAP Mail server. I'm assuming that is the problem but I can't find how to change the new setting from IMAP to POP. There is a red Delete button on the A/C settings page. Should I try that?

Also since I couldn’t use the profile from corrupted old machine I've manually input everything in the new. I have used the Draft files in the old machine as a sort of reminder for me and want to copy it and bring it Into the new machine. Is there a way to do that?

I hope this is concise enough.

I can't delete some websites from advanced tracking protection, I type in a website but it doesn't add it to the list. One site is mail.proton.me. Even the ones that are added still don't load when I open Firefox, they are telling me I have connectivity issues. This has only started happening since the last updat. Everything work perfectly on Chrome! What is the point of having tabs and pinning them if you have to open them manually every time you log on?
