i have two computers. on computer 1, all is fine. on computer 2, when it restarted after an update, i got the error message -- "the bookmarks and history system will not be functional b/c one of firefox's files is in use by another application, some security software can cause this problem." this has NEVER happened before.

i found the "how to fix this problem" page, but i am completely baffled by it. what i want to know is what security software (i have avast apps) is likely to have caused this problem, and how do i fix it (i.e., what setting should i change?).

thanks for any help you can provide. i am NOT tech-savvy, this is the only time this has happened, and i've had both computers for years. they have both always had the same apps.

Hello. How do I do if I want Firefox to open a new window every time I click on the icon? I tried to insert the command "-new-window URL", which used to work before but it doesn´t anymore. Is there anybody out there who knows something about this?

All other modern browsers have autofill as standard for names, addresses, phone numbers and emails.

I am in the UK and just started using Firefox and really love it but the problem is is that there's no way to turn on autofill.

Looking into it, the only way is to change your language to US and then the option will come up. However, it doesn't then work as it won't let you enter UK formatted addresses or phone numbers.

Why is such a basic feature missing from the UK version and does anyone know when it will release to the UK?

Thanks so much in advance.

We require disabling password sync at org-level by deploying changes in registry or Group Policy. Currently we do not see any option to disable password sync except at browser level which leaves the user in control. However as IT and security admins, we would like to implement this as a global policy so corporate portal passwords are not synced to unmanaged devices. Please suggest a solution.

I would like Firefox to save my usernames for sites, but not the passwords. However, Firefox insists that I supply a password before it will save the account details, and if I supply a dummy password, then it will not let me later edit the account and delete the password. I like to remember my own passwords rather than store them anywhere.

I have tried password managers and they are overbearingly controlling, particularly given that they don't store my passwords let alone my 2FA details, so I'd rather just use Firefox's less onerous, built-in system, if only it would allow me to save an account without a password. Surely saving a username without a password is a safe option, so why block it?

Locking this thread, please continue here: [/questions/1461407]
'DO i need to restart Firefox to get old search log-ins to pop up after making Fire fox my default browser?

Hi. I cannot use stripe payments. I am using FF vLatest and have added it to the popup blocker exception list and every other exception list I can find. I have done this for http://stripe.com and for whatever website is trying to use stripe. No stripe payments ever work and I always get the same error attached. I have tried another browser and it works. How can I find out at least what is blocking the payments so I can disable it?

I have 2 laptops, one for work and one personally. I was looking to set-up firefox on my personal laptop as well but noticed I cannot open developer console on a specific element by pressing 'q' anymore after right clicking.

This is a significant feature and I would like to keep using it. Is it possible to enable this feature on my personal computer as well? Since it is still enabled on my work device.

I've installed firefox with pacman on Linux, and I installed arkenfox. It did not work, I tried other user.js', none worked. I've also tried wiping my entire firefox root folder, then using arkenfox, but did not work.

Firefox should definitely add a dedicated option in the toolbar to make switching between profiles easier. Currently, the only way to do this is through the "about:profiles" tab, which is much less convenient than the profile switching options in other browsers

The Adobe Acrobat Add-On Extension for Firefox was missing so I attempted to add it from Adobe Acrobat Pro 2017. I have had to do this manually by installing from the adobe_acrobat-1.0-windows.xpi file. This usually has worked. When i tried to add it this time is said the add-on file was corrupt.

I tried uninstalling and redownlading AdobeAcrobatPro 2017 thinking this would add an uncorrupted file and got the same the same message. Unfortunately, because I had used the Adobe license key too many times for Acrobat 2017 on my computer I had to upgrade to Adobe Acrobat Pro 2020. i had hoped this would solve the problem. But no, I get the same message corrupt file message even with a new copy of the Acrobat Pro 2020.

What is going on? Can anyone help with this?
