Firefox Community Forum

I would like to be able to download YouTube videos.

Is there a Firefox add-on that will allow me to download YouTube videos onto my MacMini?

I tried Video DownloadHelper and YouTube Video Downloader and didn't see any action.

Do I need to setup settings a certain way to make it work?

What are the steps to make it work?

Thank you for your assistance.

sync from my other computer's Firefox doesn't seem to be picked up on the sync for the older computer. any help in transfer of data between the copies of Firefox would be helpful

with the new function of Tab Groups i was wondering if it is possible, or can be added in the future, to sync existing Tab Groups to all or specific devices in order to access created groups on my private Macbook to my work Windows Firefox.

thanx for any reply

Hello,

as the title suggests, I moved my whole profile folder to a new PC, and have since formated my old PC. I just noticed that the key4.db file is missing from the old profile folder. I have followed all instructions I managed to google, which ensured that it was enough to just copy over the old folder content into the new one, nowhere was it mentioned to look after if a key4 or key3 file are present. How is it possible that multiple of your support articles don't mention this? I am now stuck with only a json.login file from my old profile and no way to import my saved logins to the new PC.

Two issues! 1) When I access "FULL SCREEN", how do I get back to the normal desktop screen? 2) When Firefox crashes, it wipes out my tabs. How can I restore them?

i specificly have a firefox acount soo i can acess my bookmarks if something happens to my pc. now that it did and i had to format it, unfortunatly i forgot my password. i didnt even try any false ones couse usually you can save your Data by verifing your acount over emeil when requesting a new one. but after doing that its all gone. 10 years of bookmarks gone. how do i get back my bookmarks? i never agreed to this kind of security feature. i dont think its agood thing, and i never saved any infos that could get misused if stolen so such a feature as earasing my data is unwanted.

Hello I have both Firefox and Thunderbird My old laptop using WIN 10 is was past it's prime. I got a new one WIN 11 and want to pick up and move everything from both apps to the new laptop. PW saved docs e-mails and URLs everything and I just can't find a way to do it. Can someone please help me. I did install a new Firefox on the new PC but it won't work and the setting are not the same ( account settings and such don't match )

There was an update today on my PC laptop, I think from FireFox. After the restart, my bookmarks have all disappeared. The instructions to restore them are useless. I go through Menu/Bookmarks/Manage Bookmarks/Import and Backup/Restore/Choose File. THERE ARE NO FILES TO CHOOSE FROM. According to the instructions, there should be some dated entries. Nada.

I tried the Troubleshooting blahblah and that was equally useless.

I'm panicking that I've lost years of carefully organized bookmarks.

I have followed all the Restore instructions to get my 1 plus years of bookmaarks back. Manage Bookmarks application will not open or show ther ever where any backed up files. The steps " Manage Bookmarks/Import/Choose File" function never responds or directs me to select a folder. There are two folders on my Desktop that are named Firefox Bookmarks. See attached screenshots.

All of a sudden, unable to save bookmarks or to export them. Integrity report says (see below). Have restarted Windows 10 and FIrefox several times, no joy. Help!

So Firefox was failing me as it wouldn't play YouTube videos, so I tried rolling it back, which failed. So I reinstalled it and it's not saved any of my data, despite making an Old FF data folder. When I sign in with my account, nothing. I have it installed on my phone and when I try to sync it, it asks me to click on synchronise and save data, which isn't even on the menu!!!!!! How could you get such a basic thing wrong? Is that it now? I have to start right from the beginning and gradually go through every password and bookmark???

Please tell me there's a solution because this is really annoying.

Hi! So I have both a (admittedly pretty old) laptop and a desktop, and thus every so often manually move my backups to and fro. I have cookies and cache that I cannot afford to lose because there'd be no 'backup' for them, it isn't stored anywhere else, so if it's gone, it's gone. Just today I was doing the same old, going to /Roaming and /Local, zipping them, moving them over on a usb. But today I see that alot of my roaming files have a '.corrupt' and is listed as a 'corrupted file'. My firefox is still working, I'm even using it right now, but I'm nervous that could change and I might lose access to the cookies and cache. It'd also suck to lose my passwords and bookmarks as well. Any advice so that I don't get a nasty surprise later?

I just downloaded Firefox for Mac OS on my Macbook Air. Doesn't look like the bookmarks, their folders, the most recent passwords have synced from the Mobile version of the software to the desktop here on my Mac.

Hi,

I have had to reset windows, after reset I also upgraded to Windows 11. I have to reinstall all programs including Firefox but understood all my data would be available and most of it is. I have reinstalled Firefox but did not have immediate access to my old Bookmarks and Passwords etc. I have found the Windows.old file but that only contains Microsoft files, nothing from Mozilla. I use File History as a backup but only for my personal data files.Can anyone tell me if there is a way to get the Firefox Profiles back please?
