Firefox Community Forum

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 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.

I bought a new pc and synced firefox with my old pc to transfer all my tabs and accounts. The new pc died within a day and i will have to return it to the manufacturer GMKTEC, the problem i have is all my accounts Ebay, Amazon etc are on it as well as my medical data. Is there something i can do with firefox to stop this information being looked at or used.

TIA

Why am I getting the following error: "Sorry, you have been blocked. You are unable to access ssl1.prod.s1search.co" When I attempt to use the Dogpile search engine (https://www.Dogpile.com)? If you can't fix it then how can I disable it? The only reason I can its' use is to give me carpal tunnel syndrome. I don't need extra mouse clicks or the aggravation of not being able to use the search engine that I've been using as long as I've been using Firefox.

Trying to sync my galaxy S20 5G and MacBook Pro 14 inch 2023. Mozilla instructions tell me to look for an option to sync in the menu, but there is no such option on my version of Firefox on my Galaxy. It says that I have the current version of Firefox for android, but the thinking option is not available on that menu. How do I follow up?

I had a major failure and had to replace my PC. I still have to old C:\ but using C:\ How can I recover my bookmarks from the "old drive" my password recovery would be a bonus.

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!

All,

I just downloaded over a 100 images and created anew bookmarks folder, which I saved them to. I think I have some duplicates,so need to execute a sort on that bookmarks folder, which will place the duplicates next to each other so then I can find and delete the dups.

How do I do this?

Cheers! TBNK
