Firefox 커뮤니티 포럼

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

I started using a new laptop and when I receive emails through Outlook, the excel attachments won't open and I get a message saying that I don't have the pdf software. These are Excell files, not PDF. I've tried all the suggestions on-line but they still won't download as Excel files, only Firefox files.

I was able to install it on my Mac mini running OS mountain lion with no problem but This is the error message I keep getting on my IMAC OS10.15.7 Catalina (attached): current browser is safari ver 15.6.1. Your help will be greatly appreciated!

I keep getting pr_connection_reset_error messages in Firefox version 148.0 64 bit. I have purchased the windows 10 OS with extended updates and am running version 22H2 os build 19045.6937 do you have any suggestions on fixing this problem? When I am in my gmail account and using Firefox and I need to do a password reset that is when I receive the above error message.

I just switched to Floorp from Chrome. When I try to print a shipping label with my DYMO 450 labelwriter, I cannot get the label to fit properly as I can with Chrome. It is an issue with the print dialog in Floorp. It does not have the "fit to paper" selection in scale section of the dialog. This makes the label print not near as well as in Chrome. I will be switching back to Chrome unless this can be addressed. See the 2 screenshots attached to see the issue.

on my laptop the firefox search engine randomly changes to one that I don't even have checked as "search shortcuts" but are still on my "default search engine" list for some reason (but never chosen by me

I am seeing pop up ads like these on the lower right corner of my screen since I updated to windows 11. I've never seen this with windows 10. Microsoft is telling me these are coming through my browser. These are not when I am in a web site and get the pop up to allow notifications, I always say no. These come @ 1 per week or less and I don't seem to be able to stop them. Is there a setting in firefox that will stop them or is this a microsoft issue? thanks brian

Not sure if "browse" is the correct topic but here we go:

After a random crash (I don't remember the details, been a while) I've "refreshed" Firefox. Following that I started to have some problems with Google Meet. Haven't had any for years and suddenly when i open Google Meet (working from home and using Google Meet as an online meeting platform daily), everything becomes unresponsive. I can't change tab, cannot close Firefox from the close button, nothing. I open the Windows Task Manager and End Task manually to close the window so I can restart the browser. After restarting Firefox and launch Google Meet, it doesn't crash.

The other problem is when I try to watch something on Netflix, I hear the sound, see the subtitles but the video content is not present. It's just black screen with UI on it. Yes, I checked the DRM setting and no, other streaming services that I use don't have this problem. I can bypass this by launching Firefox in troubleshoot mode but I want to use my extensions. I even tried to enable them one-by-one to see if anyone causing problems but even when I disable all of my extensions like in the troubleshoot mode I'm still having the same problem.

I tried several solutions that I found on reddit etc. but nothing worked so far. I also re-installed Firefox and nothing changed.

Please help me before I lose my mind (:

Hi,

I use Firefox app in macos, android and ipados. The bookmarks across them are not synching automatically. I need to press sync manuelly to do. All apps are updated, all settings look fine. Please help me synch bookmarks across platforms. Thanks a lot.

I don't recall clearing the history.

Also, starting a few days ago, if you type it into the search bar on the homepage, it will drop to the top. What is the cause of these issues? I'm using Windows 11.

Since I upgraded to you, I am having trouble accessing important and medical info. I would like you to put every thing the way it was before. Easy access. You erraced some of my passwords, I want them back. I spend hours trying to find my info. I am 80 yrs old and do not need this aggravation. Thank you Moira

I have Firefox installed on multiple devices and most/all of them don't keep sessions or browsing history

I noticed that these files are updated while browser is open and get deleted once browser is closed:

• sessionstore-backups/recovery.baklz4
• sessionstore-backups/recovery.jsonlz4

No other files are related to sessions

I have "Open previous windows and tabs" checked

Installations:

• Windows 10
• Debian 12
• Debian 13 (Firefox 148.0 Snap)

On Firefox for Android, this issue doesn't happen, I can even see the whole browsing history including history lost on PC installations

Windows 2026-02 Preview Update (KB5077241) causes Acer laptop to crash when firefox opens when computer is started. Only on this laptop, other computers are unaffected. Firefox is the newest version and like mentioned, all other computers run the same security programs and vpn. The windows update needed to be uninstalled on the Acer laptop for it to operate correctly.
