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

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.

A few days ago Firefox started opening in a small window in the upper left corner of the screen. This problem was earlier also posted by other users. So I have read all these topics and suggested solutions.

This is what I have tried: - removing xulstore.json - compatebility tab in properties - manipulating overlapping squares icon and dragging window to almost full screen - Reinstalling Firfox ( without removing Firefox completely on forehand)

So far nothing resolves this problem.

Please advise

When I click on the Firefox icon to start browsing, the Zoom meeting program opens automatically! How do I prevent that from happening?

Thank you for your help.

Using Mac OS 12.4 and Firefox 101.0.1. After launching Firefox, a second icon appears in the "recently used" apps section of the Mac OS dock (see attached screen shot). The icon stays there and goes away, and then comes back, and then goes away, etc. This continues on and on until Firefox is closed.

Why is this happening? Never acted this way before the latest updates.

i own a macbook and have recently switched from chrome to firefox- in my mac settings, it hasnt given firefox the permissions to use my microphone or camera. it doesnt show up the usual list to be able to allow the permissions. i've enabled microphone and camera permissions for the websites i want through firefox, but i cant even unmute myself. i think i need firefox to give me a popup and ask for microphone permissions, but it hasnt done that- and even if it did, i think it would show up in the list for allowing permissions through my mac settings (it shows applications that have requested for microphone access).

For the past few days I get the request to enter captcha characters every time I try to access the Amazon website using Firefox on my Win10 PC. It works fine on my Firefox for android on my phone and also works fine using the Edge browser on this PC.

I've tried resetting Firefox. I've tried troubleshooting mode. I've tried turning off enhanced tracking. What else could cause Amazon.com to feel the need to verify that I am not a robot ?

Hello, Few days ago I noticed that Firefox started complaining about self-signed certificate issues, although I added my CA certificate to authorities months ago. It worked without any problem, but now I'm unable to open any of my internal sites anymore.

I tried to open a random site in Chrome, but the same issue. So you immediately will say the is in the certificate, but wait. I have few VMs running on Virtualbox, so I decided to test in there. Guess what, no issues at all. I tried in Fedora 25 (the Firefox version is below 100), then tried Windows 100. Both worked. Then I decided to update FF to the latest version, guess what - it broke again =]]

So something has changed, but I really don't have a clue what causes the issue. I attach the screenshot of detailed CA view from Firefox.

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

Audio was working fine until recently. Now, firefox has no audio playing on any site.

Some sites show "PLAYING" in tab, but others like YouTube don't show that notification. Even with "PLAYING", there is no audio output.

I checked Windows settings and Firefox is set up correct (and the same as it was before it stopped working), see screenshot attached. Otherwise, I restarted Firefox, tried it in troubleshoot mode, and reinstalled Firefox. No changes.

Possible system changes include: Maybe a Firefox update occured and broke the program? I installed the game Civ5 from Steam which required some Windows VS redistributibles installed.

After upgrading to v101, Firefox no longer recognizes my Self-signed wildcard SSL for *.local.dev.

Before you tell me not to use the .dev domain, I am aware that Google owns it and we're technically not supposed to do local development with the *.local.dev domain.

I have already tried the following: 1. Set network.stricttransportsecurity.preloadlist to FALSE, and everything was working perfectly fine before v101 2. imported the server.crt into Trusted Root Authorities in Windows, and also imported it in the Certificate manager in Firefox. 3. Tried other wildcard local domains like *.test.site, *.local.ddev and these don't work either.

I even tried following recent guides to issue a new certificate with openssl and SAN, and it still doesn't work.

Screenshot of wildcard SSL attached.

Hello. I just closed by accident my main window so I restored it, but it apparently lost all the container data and restored all non-pinned tabs to the default container.

Is it normal, is it a bug or is it a yet-to-be feature?

It feels like a bug because pinned tabs (which were not present/open in the secondary window that stayed open when I accidentally closed the main one) where duly opened in their respective containers.

I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Been using Firefox for long time on a Win10 machine. Motherboard failed. Saved the C drive. Question is how to move bookmarks (profile files ?) from the old C drive to the new Win11 computer? I tried moving the profiles over from the old C drive to the new computer but Firefox would not recognize them and shutdown. Restored the Win11 files and Firefox is again happy.

My bookmarks toolbar is empty. When looking through the bookmarks menu, it shows that none of my bookmarks have been removed, and they are all still listed as being present in the Bookmarks toolbar, but they are not displayed in such. To be clear, bookmarks toolbar is enabled, and I have already verified its positioning in the customize toolbar pane. There is a strip of empty space where they used to be, but they are simply missing now. How do I fix whatever issue caused the toolbar to cease displaying my bookmarks?

I have an extension (completely blank) that can't be deinstalled. I am trying to use the "refresh firefox feature" to get rid of it, but the button simply isn't where it should be. The text is german, but none if these Buttons are the one I seek.

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.
