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.

Hello, After the last MacBook Pro M4 update my tabs keep disappearing. This is quite ANNOYING as I use ALL my tabs. Plus when I go to HISTORY there is NO Restore Previous session...so I am losing EVERYTHING. Do I just need to go out to another browser and make them my default? I can find NO help when I go out to your support for my problem. Thank you, Patty

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

I want to copy/clone information in my Firefox Profile (Bookmarks, Logins, ..) from one device to another. Once that was accomplished, then I would enable Firefox Sync for the two devices.

Scenario: Device “A” (Profile A): Primary/Original/Source Device “B” (Profile B): Copy/Clone/Duplicate

I understand that if I set up Firefox Sync first and then sync the two devices what I will get is a combination/fusion of the information on the 2 devices, i.e., all the “good” stuff in Profile A plus all the superfluous stuff in Profile B that I would just as soon ignore/delete – which is not what I want. This issue has been raised in a number of other posts on this forum but with no suitable resolution offered (that I could find). I’m wondering if there might be a “work-around” that would achieve the desired result.

So ... would this work?

1) Back everything up first (of course!) 2) Glean any unique information to be preserved (Logins, etc.) from Profile B and incorporate it into Profile A (Profile A now has everything essential!) 3) Purge Profile B

   a) Create a New Profile on Device B (and delete old?)
   b) Delete everything possible from the new Profile B (default bookmarks, etc.)

4) Login to Mozilla account and enable Sync

The idea is to create a “blank” Profile on Device B so that when Profile A and Profile B are Synched together (combined), Profile A remains unchanged, and Profile B is populated with everything in Profile A (a perfect copy!). The result that I want after Sync is essentially A+B=A, the solution of which is of course B=0, hence the focus on creating a "blank" Profile B.

Instead of purging Profile B as above, an alternate method might be to first “pre-load” Bookmarks in Profile B by the usual method of Backing up Profile A Bookmarks and then Restoring them to Profile B. At this point Profile A and Profile B Bookmarks would be exactly the same and Synching the two devices should make no changes to either’s Bookmarks. Logins and other information would still have to be purged, but this could at least be a head start.

Presumably this idea could be extended to more than 2 devices (but with only one being the “Primary”).

Note that I am (myself) only concerned about Bookmarks and Logins, and am thus glossing-over how other information that might be important to others (Browsing History, Tabs, etc.) might be Synched.

Could someone from Mozilla/Firefox with a knowledge of the inner workings of these features please comment as to the efficacy of this “work-around”?

Thanks.

I am going round in circles. The last Firefox update reset my Firefox on my laptop to default settings including losing my master password. I started to reset all my old settings but when I got to the part where I setup the sync with my phone version of Firefox, Mozilla asked me to log in. My password was not recognised so I hit "Forgot password" having set up a new password using one of my 10 digit authentication codes, I was then asked to log in with my new password, I did this & when trying to do the sync, I am being asked for a six digit authentication code! I have no idea where to find this code. Please help.

Yesterday, something went wrong in my Windows 11 desktop (I have a virus program installed). One of the casualties involved corrupting Firefox (it would not open). I reinstalled Firefox without removing the old version. Now I have a new installation but all my bookmarks and other data are missing. There is a folder on my desktop labelled as "Old Firefox data". It is possible to restore Firefox to a previous time (a day ago)? Thank you.

I do a lot of research, and may have 300 - 400 tabs open. 2. I needed to do a clean install of Win 11, so I saved my open tabs as bookmark, I checked and they were all there. I also saved the folder from AppData Roaming - Firefox\Firefox\Profiles\ivdajzll.default-release\sessionstore-backups. Only when I open a tab with about:sessionrestore, the below Restore Session button is grayed out.

I then exported my book marks as an HTML file. I installed FF, opened up bookmarks manager, and chose to import from html, pointed to my saved file and selected open, nothing happens. When I look at the side panel in bookmarks manager, my book marks have not been added.

2. I also tried the second option by opening Settings / General / Import Data and Select the Bookmarks from HTML file option. I point to my saved html file, it spins for a few seconds, says success and I click on the Done button, still my bookmarks have not been added.

Need help finding my old bookmarks on my hard drive that might have been erased when I did a reset Windows 10 install. Unfortunately, I had to restore my hard drive, and the Windows 10 tech advisor didn't tell me to save my Firefox bookmarks before I started the restore process. But the bookmarks might still be somewhere on my computer? And I don't think I ever created a Firefox account. So I don't think Firefox saved them.

I have many, many bookmarks. Every once in a while I save them. My hard drive died. Geek Squad replaced it but where are my bookmarks and passwords? How do I recover them?

HELP!

Move open account to new computer, old computer died, Firefox[ Mozilla] have all my pass words also, Will not let me open old e mails etc. sync wants cell phone,it doesn't work where I live. thanks john

after reinstalling my system i culd not login to my account i have like 9 passwords and your stopid system blecked my attempts like after second attepmt so i did password recovery and changed it but after that all my sync data are gon WTF!!!!! It makes the sync function pointless and usless for its specially for that purpose !!!!!!!

Can someone help me recover my previous session. I restarted my computer, I force quit firefox before so I would restore. I restored and only one or two of the four pages I had open (with a bunch of tabs open in each).

I cant use the restore previous history tab cause its grey...

Please help.

Thank You.

I have mozilla on my pc , i use it without an account And i have many bookmarks and links i don't want to lose If i signed up now can i backup my data and save it into my new account without losing it

When I logged into my laptop on 9th November Firefox had closed. This happens sometimes, I'm often not sure why, but this time the previous session didn't automatically repopulate when I restarted. I navigated to the history options with the idea of retoring the previous session - either using that functionality or individually opening previous windows - but history was blank and the previous windows option was greyed out. Following suggestions online I've looked for .bak or .json or similar files to use as restore points but there's nothing since much earlier in the year up to 8th November, which are pretty much empty, and the 9th.

I'd be very grateful for any suggestions!

Hi, I accidentally did a refresh on my Firefox (Win 11) and therefore I now have an "Old Firefox Data" folder on my desktop and Firefox is completely almost back to stock.

I have lost all extensions, customizations, settings and other configurations. Luckily, I had taken a backup of my bookmarks prior to doing this.

How do I return everything (including extensions) back to pre-refresh state?

Thank you.
