Firefox Support Forum

Sorry to trouble you, i recently un-pinned mozila from the task bar by mistake, as its my main browser i re-pinned it from the icon on my desk top, now i have lost all my logins and passwords and some recently saved bookmarks. Would there be a way of recovering them, again sorry to trouble you. Nigel

Are there any reports of erased history lately? Perhaps since v122.01? I had history that goes way back.

I few of my profiles have a month's worth I don't sync. I have these two profiles in particular that are quite distinct from one another. Nothing in common, but both only have history for the past two days. None of my related settings have been altered.

I tried replacing places.sqlite from backups, but unless they were backed up that way, it did not help.

Hello dear Support-Team!

After updating Firefox 118.0.2, I loose all my pinned an not pinned tabs! After restarting the updated version, all pinned tabs shows a globe-symbol and the not-pinned tabs where empty. After an additional restart of firefox ALL tabs are gone.

What I tied so far: restoring the Firefox-profile from a backup -> no success. uninstalling firefox and install a fresh (newest) version and restoring the profile -> no success.

The only way to get the tabs back, is to uninstall firefox, restore the profile from backup and install the old version 118.0.2!!

Is there any reason, why this update fails? Is there any way to successful update Firefox, without loosing all my tabs??

regards WH

As I am a corporate website administrator and I use an ultra-wide monitor with a resolution of 3840x1600 pixels, I need to be able to run firefox with window size of full HD to verify the compatibility of the site for common displays.

How can I ensure that the Firefox window always starts at this size?

In the case of Chrome, you just add the parameter -window-size=1920,1080

Unfortunately, this solution does not work here (so it worked in older versions).

I found some plugins that promised this, but none worked correctly.

I find the option to set a default size to be very basic and essential and prevents me from switching from Chrome to Firefox.

Hello everyone,

I'm currently consuming APIs hosted on an external server using Java( or any other server side language), and everything works smoothly. However, when attempting to consume the same APIs in JavaScript, I encounter the 'Access-Control-Allow-Origin' error.

After some research, I discovered that browsers implement security checks leading to this issue. Can anyone advise on how to disable these security checks or resolve this issue when accessing the website in the Firefox browser? Any insights would be greatly appreciated. Thanks in advance!

When using multi-point headphones (I'm using open-runs) that are connected to my Windows 10 computer, while Firefox is open, the headphones think that audio is playing, even when it is not.

Closing Firefox fixes the issue, but playing any music from youtube/soundcloud and then pausing it does nothing to tell the multi-point headphones that audio is no longer playing.

Any help on getting Firefox to not do this is appreciated.

I have tried using autofill for credit cards. The pop up to enter a password pops up and I fill that in. The credit card options are there and I click on the one I want and nothing fills in. I went to settings to turn off the request for authentication, unticked the box, and see no where to save that. When I refresh the screen, the box is once again ticked.

Hello, Firefox is set as my default browser. However, when I click on a link in an email or website, it always open in Chrome. I cannot get it to open in Firefox. thanks for your help.

Здравствуйте. К своему стыду не могу разобраться. Поставил опции, во вкладке безопасность, удалять Куки и Историю по выходу из Firefox. При этом история сохраняется, при последующем запуске браузера. Так же при следующем запуске браузера, при авторизации на сайтах, автоматически заполняется поле "логин", "телефон". Как сделать что бы не заполнялся и была очищена история? Спасибо.

I have the same problem https://support.mozilla.org/en-US/questions/1421734 it's not a pdf. If I want to print a shipping label from eBay using Firefox nothing happens if I try to make it bigger. I can make it smaller but it is too small to begin with. If I use Brave or Edge (using the same printer) it works I can adjust it and make it bigger up to 200 %. I have already reset the printer options in Firefox and tried when disabling all add-ons.

Firefox crashed and when it did all my history was gone. All of it. For months if not years. I need to get the history from about the last month back. I am not asking for community people to answer as I already checked that and there is no accountability, clarity, ability to confirm etc. etc. etc. I am asking the engineers at Mozilla to please give me the method that will surely work and is user friendly. I am willing to pay a small fee if necessary.

For years we have been able to login to two different websites running on different ports on the same host with our Firefox browser (The last working version was 102.14.0-3.el7_9) our RHEL 7.x system. When I accessed the different sites, there was two Authentication Decisions, one sending one cert (We will call it CertA) to the system and the other listing sending a different cert (We will call that CertB) to the system, same hostname though.

I updated the Firefox browser to 115.7.0-1.el7_9 and ever since, when I navigate to the first website, it remembers the first Authentication Decision to send CertA to the system and works as intended. Then, I try to navigate to the second site and I never get prompted to pick a cert for the second site (CertB is what it should prompt for) and the connection attempt fails with a "Secure Connection Failed, Error code: SSL_ERROR_UNKNOWN_CA_ALERT" message.

If I go and delete the Authentication Decision for CertA, then go to the CertB site, I get prompted for the cert decision and I am able to login just fine. But, then if I try to go to the CertA site, I get the same error listed above.

I can use a band aid to check the "History > Always use private browsing mode" checkbox (Which never remembers the Auth. Decision) option in Firefox, then have to remember to close the browser each time I want to navigate from one site to the next. But I have never had to do that in the past and wondering if this is a new bug or if it is somehow considered a "Security Feature" or something.

I searched around the net a bit and couldn't find a way to manually add an Authentication Decision myself. Is that possible somehow with a config file edit on our Linux system somewhere?

Thanks kindly ahead of time for any consideration to my issue.

i made a custom firefox colour setup for my desktop machine, and it doesn't have any option to save it- because of this, on my laptop which is synchronized to my desktop's firefox settings, it is not showing up at all and if i go to firefox colour it isn't there for me to add. so how do i DO this???

i do not want to maker my custom setup public so it is not available to all, it is my own setup using some of my own artwork which i do NOT want made public on the internet.

there MUST be a way to save it however and let my laptop's firefox also display it,m yes???

and on that topic, why isn't it just automatically synchronizing when everything else does?
