I am trying to 'fork' my FF, duplicating my profile on to a stick, then modify each one so that my work related bookmarks, saved passwords, cookies, history etc are in one profile, and my social/general bookmarks, cookies, passwords etc are in the other. I have done this and using about:profiles can open the non-default (USB stick) profile in a new window, or set the non default profile as default, close, re-open FF into the alternate profile. All good so far. However this isnt working quite as I expected. If I switch to alternate profile, save a bookmark to the shortcut bar, then switch back to the other profile then after a second or two the bookmark I saved in the other profile appears on the shortcut bar?!? This happens whether I have opened alt profile in a new window, or have changed the default profile and restarted FF into the other profile. Is this because in both instances it is using the same local directory? The doesnt seem to be an option to choose a different local directory for the alt profile. This would be ideal if possible as it would ensure that there are no data crumbs left on my PC when using the USB stick profile which is important for my work security. Any help really appreciated.

I do not get this on Edge browser.

I know register an account and login both Mac. But looks like they are two different accounts! I confirmed both Mac are on latest FF 103.0.2, I login the first one with my id, register it with my email. Then when I try to login the second one, it is asking for register again! Not login! So they always have different bookmarks. I've tried two id, drhtd@163.com and gyfguo@cn.ibm.com, both can't work, any help is appreciated, this bother me for long time.

I woke up this morning and my tab bar on Firefox was out of control. I figured out how to shrink the tabs in about:config. However, there is a huge space at the end of the tabs that is completely unnecessary. I've been googling all morning. I tried to find compact mode--but "density" is gone, even when I go back into about:config and enable it. The only other help I found was to change the CSS code and unfortunately, that is outside my wheelhouse.

Is there ANY way I can get my old tab bar back so that the tabs fill the top of the screen as opposed to having a huge empty space at the end?

When I go to my bank's login site, I get a message saying that I need a newer browser. I have the latest version of Firefox, and I used to be able to log in just fine, but I recently reset my browser and I seem to have lost some settings. I have tried adding an exception for this site's cookies in Settings, and I've also tried turning off enhanced tracker, but the site still doesn't work. Is there a way to tell what is broken and then fix it? Thank you.

I'm using the latest version of Firefox on Mac OS X 10.14.6.

Whenever I go to print PDFs from Firefox, usually through Gmail, if there are any images in the PDFs they are blown up way past their margins and rendered unreadable. This isn't a huge issue but it is affecting some text as well, meaning I can't print the documents directly from Firefox. I can download the documents and print them from Preview just fine, so it isn't an issue with the printer.

I'm attaching a screenshot of my print settings and an example of what Firefox is outputting (converted to JPEG so I can upload it).

I'm a hobby-programmer not trained. My doc is local php file, saving calendar events to text files, run on localhost. The field in question is a line number on my calendar. Javascript uses that number to load another input with the calendar entry so I can confirm that it's the correct line before submitting it to PHP for deletion. I have unchecked 'Remember search and form history', ran 3 cleaners, restarted the computer and the data is (correctly) not displayed. But it is not deleted. When I rechecked 'Remember search and form history' the old input data comes back. If I change id, field name, javascript function name and variable names the history disappears but when I restore those names, the history is back. I want to know why that input can't be permanently deleted. Windows 10, Firefox 103.0.2 (64-bit)

Hire staff instead of your blind leading the blind approach would be appreciated.

Case in point, password security regarding access to my Last Pass vault!

Through one of your updates, my master password to access my Last Pass account is shown which allows anyone to access my last pass vault. Your instructions are useless and incorrect and your real support is a joke.

If you have an accurate solution that applies to your CURRENT version, I would appreciate your help.

As a FYI, Chrome and the other normal browsers have retained the requirement to provide their master password to gain access to my Last Pass vault.

Aside from this issue and lack of real support, your browser is great. If I can's get a solution from you, I will have to stop using your browser.

Yesterday (08/10) I ran a supplied update and suddenly the blank white screen problem was solved. Today when I try these same sites the problem reappears. Who sent out the update? Why does it not work today? This is only a problem on my desktop. I can still see the sites on my iphone.

My printer is printing invoices from ebay but the logo and image previews are now larger (and cropped). I tried resetting the printer no luck I logged into the same area on Safari and produced a pdf that printed fine When I went back to Firefox and generated a pdf (print using the system dialogue..) it generated the sam problem

To be clear - The images are much bigger but cropped in the window dedicated to displaying it on the invoice so it only shows a small section of the image.

is this a current bug? How do I get help from a trouble shooting chat window? Thanks Mac Monterey Firefox 103.0.2

Up-to-date Firefox on Windows 10 laptop. Today, for the 2nd time in a week or so, the “mailto” function has disappeared; i.e., if I click a “Send email” link on a webpage, the Windows dialogue box to select a mail app pops up. When I check the applications setting, mailto doesn't appear in the list.

The first time this happened, I found online instructions to refresh Firefox and select Gmail as the mail client. I don’t mind doing it again, but I am concerned about the problem occurring so soon after the recent refresh.
