Firefox 技術支援討論區

1. i have firefox on my pc, now i installed it on my laptop 2. synced to my account on laptop 3. the internet went out halfway through the syncing process (only 3 addons or so installed and then it got stuck) so i closed my laptop and forgot about it 4. i opened firefox on my PC and the account synced 5. the addon bar flashed and all the addons except for 3 are now deleted (they are NOT disabled, they are completely gone from the addons page)

I don't remember the name of every addon i had installed but I need them back.

I was trying to use the sync function on my MacBook Pro. However, the browser does not seem to log in at all. In the top right menu, it still shows the "sign in" button, instead of my email address. (see the attached pictures which I captured from my mac and a virtual machine running Firefox ESR on Debian. Another test on the flatpak version on the vertural machine apears to be normal.

Checks on account activities indicates the login histroy exsits, yet the syncing function remains unavailable.

the browser on the Mac is Version 102.0.1 (64-bit) which apears to be up to date the browser on the virtual machine is Version 91.11.0esr (64-bit)

information for the systems and machines can be found in the pictures attached.

Hi guys.

I'm wondering if it's possible to send tab from macOS Firefox to another device... I couldn't find any clue to achieve that, since that right click doesn't have the option to send tab throughout the devices like on windows.

Tks.

I know there's [[an article|https://support.mozilla.org/en-US/kb/sync-custom-preferences#w_sync-custom-preferences]] on how to sync custom preferences. I wanted to sync my toolbar customizations and some other preferences like disabling disk caching. And I don't even have other firefox instances, instead I just want to sync only on one device, so that I can continue the same setup when I signin later on the same device.

I've tried to add services.sync.prefs.sync.browser.uiCustomization.state, "services.sync.prefs.sync.browser.cache.disk.enable" and set it to true. But it doesn't work. What am I missing? No one seems to address this. May I am missing something.

my passwords and logins are not showing..!! even my bookmarks are not showing on firefox after i logged in using my firefox account. please help me resolve this its very important Sir/Ma'am.

Hello,

I have 3 different profiles and I'd like to have a visual indication of the currently active profile. I've found that using themes is the best option (a red theme for production, green for test, grey for default) but I can't prevent Firefox Sync to sync the active theme between my profiles.

I have set both services.sync.prefs.sync.extensions.activeThemeID and services.sync.prefs.sync.lightweightThemes to false and restarted all my Firefox profiles.

After a while, all windows/profiles are synced to the same theme.

Are those settings really read by Firefox Sync ? I'm on Windows 10, Firefox 91.10.0esr (32-bit)

Thanks in advance for your help !

My old PC still shows up on sync. I can't remove it because I took it apart when I built my current PC to reuse some parts. Is there a way to remove it from sync or am I stuck with it showing up?

Hello Please explain to me how to transfer tabs from desktop to Android phone because there is no option on my desktop browser settings and no matter how much I sync, the desktop tabs will not be transferred to the phone again. please guide me

I’ve not had much success with my online searches to learn the details about what takes place when Firefox syncs browser information across devices. To keep things simple, assume I interested only in syncing bookmarks and staying within the Firefox environment, i.e., no syncing to another browser. Please note that I am NOT asking for help in setting up Sync on different devices or in how to turn Sync on and off. Rather I am seeking help to understand what “sync” means, that is, the details of the sort of information transfers that take place between individual devices and the Firefox Sync server.

Here’s what I currently understand. After signing in to my Firefox account on Device 1, setting up syncing on that device, specifying that I want only bookmarks to be synced, and turning syncing on, the set of bookmarks on Device 1 is sent to be stored on a Firefox server. After that, whenever one is signed in to the Firefox account on Device 1 and syncing is turned on, any changes to the bookmarks on Device 1 will "automatically" (but I don't know how quickly) end up being reflected in the set of bookmarks stored on the server. Fine so far.

In addition to Device 1 I have another device, Device 2 which has not been set up for Firefox Sync. It has its own set of bookmarks. Some of them are also on Device 1, some are not. I sign into my Firefox account on Device 2 and set up syncing on it. I follow the steps for doing this in https://support.mozilla.org/en-US/kb/how-do-i-set-sync-my-computer, “Connect additional devices to Sync.” I then click Sync Now. OK, now what happens?

1A. Do the bookmarks in Device 2 get added to the bookmarks stored in the Firefox Sync server? 1B. Do the bookmarks NOT in Device 2 get deleted from the bookmarks stored in the Firefox Sync server?

OR

2A. Do the bookmarks stored in the Firefox Sync server get added to the bookmarks in Device 2? 2B. Do the bookmarks NOT stored in the Firefox Sync server get deleted from the bookmarks in Device 2?

After whatever transfers of bookmark between Device 2 and the Firefox Sync server take place, and assuming that I’m still signed in to my Firefox account on Device 1 and that syncing on that device is still turned on, what sort of transfers of bookmarks takes place between the new set of bookmarks stored in the Firefox Sync server and the set of bookmarks already on Device 1?

3A. Do the bookmarks then present in the Firefox Sync server get added to the bookmarks in Device 1? 3B. Do the bookmarks no longer in the Firefox Sync server get deleted from the bookmarks in Device 1?

Finally, what happens to the set of bookmarks in Device 1 and Device 2 if I’m simultaneously signed in to my Firefox account, syncing is turned on in both Devices 1 and 2, and a bookmark is a) added to either device OR b) deleted from either device?

I’m sorry this message is so long, but I’ve wanted to be clear about the things I don’t understand in regard to Firefox Sync. I’d really appreciate what anyone can say to help me clarify these points. Thanks so much.

Following direction on Help Page - Trying to sync tabs, bookmarks etc from one laptop to another. In settings, devices are said to be logged in and sync set to sync pretty much everything. Clicking the menu top right - only shows my email @ the top, then New Tab etc - but nothing about "Sync Now" or "Sign In" What am I missing? TIA, Jean
