Firefox Support Forum

Hi

We recently implemented CatoCloud to update our company's security measures. However, we've encountered an issue where Firefox updates are not possible on PCs configured with CatoCloud. The suspected cause is the TLS Inspection feature. Currently, we've allowed an exception for the entire mozilla.org domain in the TLS Inspection settings to enable Firefox updates.

However, we are concerned that exempting the entire mozilla.org domain might be too broad. We would like to know the specific domains or IP addresses that require exception settings to ensure appropriate configuration. Could you provide guidance on the necessary exception settings for domains or IP addresses related to Firefox updates?

regards,

I kinda-frequently find myself in the situation that Firefox already downloaded an update, but some time passes before I bit the bullet of actually restarting it. So a new update has appeared - but I can't download it until I restart. So I will have to restart, reload session, download new update, restart again, reload session again.

So it would be great to be able to tell Firefox to forget about the already-downloaded update and just download the latest one. Can this be done?

(The reason why I delay restarting is because I have an unhealthy amount of tabs open, typically with many things in flight; so restarting makes me lose those things, plus there's always the possibility of some trouble while restoring all the tabs)

FWIW I'm in the Beta channel.

I am conducting research and Firefox keeps on deleting my browsing history. I have already extended the history limit in the settings and that has not helped. I believe I may have missed a setting. I would like for Firefox to remember my history as long as possible to better aid me in my research.

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.

Today I lost internet access. While it was being restored I was trying to access a local server on my network that does have an https certificate. While the internet access was down I was unable to connect to that server using firefox and I had to fall back to Chrome. I couldn't see any option to ignore or accept the warning and continue at my own risk.

When browsing in Firefox and I'm trying to select buttons to click, Firefox often now shows me a menu instead of allowing me to click. I have to migrate away from the button elsewhere on the page a few times and then get back to the button. Sometimes that works. Sometimes it doesn't. Why is it doing this now?

Dear Team,

Since one day my tabs crash, in the beginning it was only once per hour, by now it happens every 0.5 seconds. Crash report id: bp-85d2c8d1-94f7-4fd9-bc8b-a1d480240209 I reinstalled the newest version and I tried starting in troubleshoot mode but crashes still happened the same way.

Update: Restarting my computer fixed it :'D

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.

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!

Trying to use a dapp - ape terminal- to connect metamask wallet. I have disable all other extensions. i have disabled and re enabled metamask but error "metamask not detected". The same dapp is able to connect with metamask on chrome. Not sure what is the problem with Firefox.

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?

I would like to use the Firefox Container tabs. I understand how they group tabs in different catagories keeping cookies separate and making your browsing more private. I use an add-on tool that groups tabs so that I can open an entire set of tools at once. Can I use the Firefox Container tabs in a similar way? I'd like to be able to select one container and have all of the tabs in that container open at once.

Hello, I have been looking at my traffic and discovered that my firefox for some reason does multiple DNS queries for the same domain, usually 6 times or 3 times, why is that happening I have checked with chrome and it does only 1 request per domain name.

I have attached a wireshark dump, the response is there instantly in very few ms yet it keeps querying the same name again.

My version is 115.3.1esr (64-bit) I have checked in about:config with dns and couldnt find anything relevant.

I have a local server where I host several apps (URLs such as http://192.168.0.101/). I've noticed that Firefox will not offer to autocomplete text boxes and forms on local pages.

I have the "Firefox will Remember history" option enabled, and autofill works elsewhere as expected.
