Firefox Community Forum

My bookmarks, history and passwords have disappeared. I looked at the articles, refreshed firefox, have restarted firefox and my computer multiple times but cannot retrieve them.

This is the message when I start firefox

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

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.

My bookmarks toolbar is showing, but it's empty. All of my bookmarks are gone.

I went to a websites and attempted to add it to my bookmarks toolbar, but Firefox failed to add it to my toolbar.

I'm not able to uninstall PWA apps created in Firefox 143.0.1 using Windows 11 usual uninstalling procedure. If i click "uninstall" in Windows Start Menu the app remains installed. PWA apps created with Firefox do not show on Windows 11 installed apps list so I cannot uninstall them. I haven't found any guide on the web on how to uninstall PWA created from Firefox. So, how can I effectively uninstall those PWA apps? Thank you in advance for your kind answer. Regards.

Hello. I have a question. When I scan a PDF file in Firefox, it opens in a new window. Why? I don't mind it opening in a new tab, so I would prefer it to open in a tab.

Every time I update my drivers for Nvidia it of course reloads the screens. This causes all the tabs in Firefox to become separated on the Windows 11 taskbar. In other words, it looks like I have a new firefox window open for each tab (which I'm assuming is how it works but it's hidden most of the time).

It's not a HUGE deal per se, but it is kind of annoying. I have to close then reopen Firefox.

Hello, I wanted to create a script that doesn't allow me to disable a certain extension. For that I thought to locate the file in which the states of extensions are put. I searched online, and the answer appears to be that such file is available in extensions folder in my profile. However, I am unable to find extensions folder under my profile.

I would appreciate the help.

Hi, I am having this problem where I am watching a video and there is a very annoying white line at the top of the screen, I have already tried the trick to turn off the titlebar but its still there. My version is updated all the way as well, what do I do now?

Does Firefox support webAuthn passkeys stored by the browser? I have an app that I am working on and I would like to be able to use this feature.

If Firefox cannot store passkeys can you explain why this has not been added?

Firefox used to close completely when I close the last tab. The last update broke that behavior. How can I get it back the way it was? This new behavior is sick!!!

I used to be able to clear all data with no problem, but now it's holding to Gmail login data (I think that's the problem, anyway). I clear all data after each browsing session and have been doing so for a long time, but it's not working anymore. But it is working on my husband's laptop and we're on the same version of Windows (11) and have the same settings. Can someone please assist in figuring out what's happening behind the scenes? Thank you!

Hi,

I have 2 machines (Win10 and Win11) with FF 140.3.1esr (32-bit) installed which demonstrates the same failure when I enter one site's url:

PR_CONNECT_RESET_ERROR

Chrome at the same machines goes at this url w/o any failures. Any ideas what to change on "about:config" in FF to allow it opening this url w/o such error?

I have pop up blockers set to allow pop up blockers, but ev en though they are turned on. Firefox will not allow pop up windows in the learning management software (D2L brightspace) used at my university.

Two questions .......... You have my operating system as windows 10, it is windows 11 ??? ......... 2nd question ......... when I bring up Firefox it shows the weather for Chicago, I live in Minneapolis/St. Paul area, following your weather location change instruction, the weather still goes back to Chicago.

This has just started happening today. When I open FF my recent tabs do NOT open. I have the option selected in settings to open with recent tabs. In history I do not have the option to re-open recently closed tabs.

Any suggestions how to fix this defect?
