Firefox 技術支援討論區

Ok. The update downloaded 2 1/2 days ago. I've used Firefox since that download. It didn't install until now. 2 1/2 days later. Why the long delay? And why don't you have something show up in the banner or toolbar that designates that an upload to Firefox is happening? Now, we all have to guess why Firefox is behaving slow and erratic, close and re-open, and check for version.

My current install of Firefox seems to be corrupted, because every time i try starting firefox, even in safe mode, it says "Could not load XPCOM". So my only option now is to reinstall, but i have some password and my search history and bookmarks and generall data to backup. So my question is how can i do this. Im on a Windows 10 22H2 Machine, and i am a pretty expirienced computer user.

Hi there

This seems to be an known issue.

I deinstalled my Firefox and it created autmatically Desktop\Firefox\old data

I want to transfer my old data (esp. for my PW+Logins) and it goes nowhere

I found the files keys4 and login, copied to my actual Folder (after reinstalling). But it doesnt do anything.

I also copied the whole "old data" Folder to the new directory and overwrote it. Didn't help either.

Is there any way to get my old Logins/PW from this old data Folder or is it just a wast of time ?

Thank you for helping.

Best,

New computer (Windows 11) shows 'Old Firefox Data'. Opened hidden files. Using File Explorer found Profile Folder & renamed it 'old'. Copied and pasted 'Old Firefox Data' as new profile. Firefox would not open. Had to remove etc and Firefox worked again. Thought this maybe the easiest way to get my Bookmarks back.

PS Presume Profile Folder does not contain Thunderbird Addresses?

My old computer crashed. I have the hard-drive in an external case and have it connected to my new computer. I installed firefox on my new computer, but I can't figure out how to get the passwords from the previous profile to my new profile. I have located the files on the old hard drive, but import will not work. Is there anything I can do?

Firefox browser no longer on W7 laptop. Followed instructions-downloaded setup and installer. Neither will do anything - message says no program association to implement thses files. Help!

I made my account via the ‘create w google account’ option a few years ago, I can still access my morzilla account through this option, but I can’t sign in in browser, just on the website. It says the password (the one that logs me in via my google acc) is incorrect. I really don’t wanna reset my password, since keeping my data is the only reason I’m still on Firefox.

Dear Community,

I am trying to download a large file. Am on a course, and the main tutor has given the group a file to download. Have tried downloading this 5 times, but get little luck. The file that I would want to download is 8.5GB, and the furthest I get is about 4GB.

I have 2 questions about this.

1) I seem to have a very 'in and out internet connection. It seems to go down at times for no reason, cutting off the download. Is there anything I could do about this? How could I troubleshoot this, please? 2) Does anybody know of any special tools that I can use to download in a more efficient manner, please? Perhaps an extension for Firefox might be able to do this, perhaps? Kind Regards to Anyone Answering this Query, Marek

Hi. I have version 99 and need to upgrade to the latest. When i tried, the saved passwords dont show up. What versions to i need to upgrade to first to step it up with the passwords and where are links for those older versions? Thanks

Please advise if it is required to have two copies of Mozilla Firefox installed. I have two copies installed, one installed on 5/11/2023, version 109.0.1, the other installed on 12/29/2023, version 121.0. Thanks in advance for your assistance.

Hello

I have been using firefox sync for a long time to migrate between PC to PC

My firefox sync profile is full of old stuff and I would like to clean up my settings by wiping out my firefox sync settings and starting fresh.

However, before doing that I wish to export all my data/settings/password/cookies/bookmarks and everything, so files on my computer.

Files that I can read in notepad and inspect. See which settings I have in there and decide which settings I want to put back in my new installation.

I have found a locked question about this on this forum

https://support.mozilla.org/en-US/questions/1065938

It mentions two plugins for this purpose

FEBE (Firefox Environment Backup Extension)

OPIE

Unfortunately and worryingly, they have been removed from the firefox addon store

https://addons.mozilla.org/en-US/firefox/addon/febe/ https://addons.mozilla.org/en-US/firefox/addon/opie/

I found a wikipedia article about FEBE

https://en.wikipedia.org/wiki/Firefox_Environment_Backup_Extension a very old link to download a probably broken version https://febe.en.softonic.com/

and a reddit thread about FEBE which states that there is no equivalent and that it is not possible to export firefox settings anymore

https://old.reddit.com/r/firefox/comments/t2zmjb/febe_alternatives/

as for OPIE, I am unable to find explanation of what it was, where it went or who used it

I know that my profile is stored in

C:\Users\user\AppData\Local\Mozilla\Firefox\Profiles\4vdt083m.default-release

However the files and structure in that folder are inscrutable

I would like to have control over the settings of my browser, what they are, to save them and modify them on my own terms.

I would like to export about:config completely to a regular plain text file, edit them and import them back in.
