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 signed in to be sure to save my bookmarks and i lost them instead. When i hit sync, i wanted to backup my current bookmarks. Instead, I lost them. It reverted to the old bookmarks i had a few weeks ago. I lost all of my bookmarks from the last few weeks. HELP!

I don't know where to add shortcuts all at once instead of adding each one individually, I tried to search for a "shortcut folder" within the bookmarks manager and i found nothing, is there anything I can do to move opera browser's speed dial bookmarks into firefox shortcut

When trying to open sites from my email, such as usps.com, I get the following message and it will not allow me to open it even if I put the address in myself:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at tools.usps.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

PLEASE help me find this problem. Until the last update, I didn't have this problem. What do I need to do? Thank you

Hello Team, I am trying to install extensions to my Firefox on Macbook Pro M3.

Getting error in the subject

An unexpected error occurred during installation.

Extensions I have tried to install so far: AdBlock for Firefox by AdBlock uBlock Origin by Raymond Hill

Both are failing with the same error.

I have tried reinstalling Firefox, Private Window, nothing helped. It did work for me with Firefox on Macbook Intel

When Firefox opens it opens 2 additional tabs. I have not changed anything in settins. Syarted happening a few weeks ago. How can i prevent Firefox from opening2 extra tabs?

I am trying to buy something online. When I go to pay for it, I was unable to do so. The was unable to type in the three number on the back even though my credit card is valid and doesn't expire until 2027.

- 1. 未使用EasyConnect VPN链接能正常访问 - 2. 只要一打开EasyConnect VPN 并链接，FireFox就不能访问任何非VPN网页提示“呃…找不到此网站”，但是其他浏览器就能访问 - 3. 如果在打开VPN之前留在页面，只要不关闭页面就能继续访问，一旦关闭页面重新打开就会提示：“呃…找不到此网站”

Microsoft recently decided to update Firefox, since when I have found it unusable, particularly where accessing my webmail (on Vox) is concerned. I tried going back to an earlier installation of Firefox and reinstalling that, but still have no luck. Please tell me (although not by email, obviously) how I may access my emails. Telephonic communication is difficult because of weak or often absent signal, but people seem able to reach me on WhatsApp - same number: [edited phone# from public support forum]

usually whenever a page of a website is bookmarked, a blue star is visible at the corner of the address bar, mentioning "edit this bookmark" when you hover on it. however while browsing thru a google doc, depending on which paragraph the cursor is located, a URI fragment such as "#heading=h.xxxx" being added. it appears that firefox is too strict about such a minor change in the URI, causing firefox to stop detecting the page as bookmarked, and displaying an empty star mentioning "Bookmark this page" instead. this behavior is observed in google docs, but is not exclusive to any specific website.

This is a really strange problem, something I have never encountered before.

I have two- near identical desktop computers Computer 1 is an HP Elite Pro 8300 Computer 2 is an HP Elite Desk 800 G1

Both have the exact same latest version of Windows 10 (Pro 64 Bit Version 22H2) Both have the exact same version of Firefox (133.0) Both Firefox browsers are synced via my Firefox account, so same Settings, same Bookmarks, same Extensions etc.

Yet one of them has a problem with remembering certain input field criteria (although they both remember passwords and usernames just fine). I have uploaded some screengrabs as one illustration of this problem

Essentially, this a courier website which I use for sending packages. I have a site ID number

When I use Computer 1 to make a booking, it has always remembered my Site ID. When I open the page, the SiteID field is already filled in, and the "Remember Me" checkbox is already checked. See Computer1.png

However, when I use Computer 2 to make a booking, I have to enter the SiteID every time, even though I check the "Remember Me" checkbox, and click the "Book a Pickup" button, the next time I open the page, the SiteID input field is blank, and the "Remember Me" checkbox is unchecked. See Computer2.png

At first, I thought it was a problem with the computer, but I tried using Chrome on Computer 2 and it works fine . See Computer2A.png

I cannot think of anything that might be causing this. I have even gone through the Settings pages side-by-side to make sure all the checkboxes are identical. Nothing different that I can find. There are other web pages that do similar things with fields that are not usernames or passwords, but all passwords and usernames for the other website I login to are remembered fine, and they are all listed in the saved passwords section of Settings.

Any help or ideas I could try would be appreciated.
