All Products Support Forum

We have around 1000 Firefox installations on our government organization, all installed via the Firefox MSI installer. Unfortunately, we came late to realize that the Firefox ESR would be a much more suitable product, compared to the normal Firefox branch.

Now, some years ago we would simply mass uninstall the normal Firefox and mass install the (latest) ESR version and all would be well. Problem is that we have to keep existing profiles (including passwords/bookmarks etc), something that is not supported in the latest Firefox builds.

Can anyone offer some advice/"hacks" to accomplish this? Note that whatever we'll do, we'll have to do it automatically, we lack the man-power to do this manually on a system by system basis...

Thanks in advance for any information provided.

Hi, I have tried all day trying to get rid - of SaveFrom.net Helper - no luck. Latest Firefox running on latest Win.10. So frustrating, tried all sorts of tricks and nothing works Cheers,

Dear all,

I am planning a move towards the Firefox ESR 78.6.x. Currently my customer is using the Firefox Rapid Release 84.x and need your help with the profile migration. The customer has a very isolated on-premises environment and does not allow the users to login into a Firefox-Account. Therefore the settings for Cookies, Cache, History and especially Bookmarks are not synched.

Environment details:

• Enterprise environment with several tausends of clients
• All clients on Windows 10 Enterprise between 1809 and 20H2
• All clients have always the newest Firefox installed currently 84.x

This creates a huge challenge to sync this stuff. Therefore I have now identified the following two options:

1. 1 Allow the downgrade by using the environment variable MOZ_ALLOW_DOWNGRADE on Windows. For this option I am trying to find the real reason why this "Downgrade-Stop" has been implemented in the first place? What risks in detail do I take to allow this downgrade? Has anybody done this before and do you mind to share your experience here? How many issues did you face and how did you remediate the issues?

1. 2 Hand over the migration to the users. Copy their current profile to their desktop and ask them to import their bookmarks manually. Not preferred by users and I can't even blame them for.

Is there any other way to automatically sync the profiles from 84.x to ESR 78.6.x without user interaction?

Thanks in advance Amir

Since Firefox allows users to install to individual profiles, how do admins go about uninstalling it for all users silently and remotely? If all 1000 PCs have 50 users, all with Firefox installed to individual profiles, I can't imagine IT admins would have to find the appdata for each and every user and modify a script for each machine and every user. There must be a simpler way, right? An "Uninstall All" for Firefox?

Hello I'm working at Imperva which is a security company. One of our product is Web Application Firewall. In this product one of our feature is to identify the application that is used when sending request to a web service. This may help our customer to set FireFox request as legit. One of the attribute that helps us doing it is the request header User Agent. We have found that FireFox which is installed on Ipad generate the following User Agent without the keyword 'firefox' (while Desktop FireFox and IPhone firefox does) Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_4) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.1 Safari/605.1.15 (Note that this User Agent ) Because the User Agent is very similar to Macbook Safari application, we can't classify FireFox on Ipad.

Is there any reason why this is the implementation? Can you update the User Agent in the next version in order the security product will be classify it?

My purpose is deploy specific Certification Authority, which is available in network share, to Firefox by Active Directory group policy (Windows 2012 R2) or alternately to set 'security. enterprise_roots' to 'enabled' so that Firefox can use Windows Certificate Store. Clients are using Firefox on Windows XP, 7, 10 and consequentially different Firefox version. Can I apply my task ? Suggestions ?

Multiple banks are removing Firefox due to vulnerabilities. They have found as I have told them multiple times that there is no centralized method to ensuring firefox remains up to date. The admx files from github do set the appautoupdate and backgroundappupdate to a value of 1 to indicate updates but all PCs are at different levels from 90.0 to 95.0 and I've found that even with the auto update switch on that many pcs do not auto update due to users leaving firefox up and ignoring the restart. The autoupdate task runs only if the user is logged on and that allows users to browse with an insecure version of Firefox that can lead to data breaches. CVEs lead to threats to exploit the CVE and that leads to risk that leads to data breaches. These CVEs are tracked by the NVD and this puts security in the hands of users instead of the business and the business has decided to remove firefox from their environments due to this fact.

I know mozilla is NFP but to maintain firefox in an enterprise environment, it need a better update process such as Google Chrome and Edge Chromium.

CVE-2021-38503 CVE-2021-38504 CVE-2021-38505 CVE-2021-38506 CVE-2021-38507 CVE-2021-38508 CVE-2021-38509 CVE-2021-38510

The above are current CVEs of High risk in one environment that has decided firefox will no longer be used.

Managing thousands of FIreFox Instances on Windows 10 systems across our enterprise. Need "Polices, Settings" to apply to firefox (GPO, Intune) to "force" updates for all Firefox Versions to latest version and maintain latest version for instances as they are released. Currently, Firefox, Prompts end users if they want to update which is normaly dismissed and the instance remains outdated. In addition, Windows UAC prompts for elevation, which some users do not have rights or the user chooses to not allow. Either case Firefox does not update and remains outdated and vulnerable.

Chrome and Edge browsers all support regular "Forced" update cycles (weekly). Looking for similar service\polices for Firefox to ensure all systems are always running the latest Versions.

Hiya, So I have used the link below as a guide to get firefox to autoupdate on users computers via GPO.

Firefox is now crashing on multiple Computers, I think they might be crashing while trying to update themselves, as per GPO.

Any help please , crash report attached

Hello everyone,

I got around 50 windows clients to deal with and I wonder how to create a customized version to distribute via Kaspersky Security Center.

What I intend is to create an .msi, a folder or something to install. It should include some extensions like ublock or https-everywhere and such. I also like to have a customized theme included.

There are some ressources like AutoConfig or GPO GPO or repackaging installer. But I don't know if the procedures still work since the documents are three years old and, to be honest, I didn't manage to get anything work that way.

Isn't there a simple way to roll out Firefox in a company with some customization?

Thanks.

Good Morning,

In my organization some years ago I pushed to have Firefox as our default browser and finally was accepted. It has been very good as we have over 10K employees using it. However this last week there has been a new release that forces you to create a new profile, one that is achieved all of you original settings and data are gone. We are a health care organization and cannot have this. I sent the fix (about:profiles) to our triage support department. However once the old profile is chosen and made the default. It will revert back to the new one each time you restart or the next day. I need a permanent fix, is there a way to update the old profile to the new version of Firefox? Shouldnt it stay the default once you make it so? I am getting inundated with calls over this, please send the fix asap.

Dear guys,

Last time we have issues with Firefox installed in our corporate network:

sometimes we are not able to load sites on different tabs, a browser refuses to load them at all. Reload function doesn’t work also, but after closing and opening again the browser is able to load sites in a normal way. This issues is observed during a day with no visual reasons on different computers with different users.

OS information: Windows 10 Pro 21H1 19043.1110

Meanwhile Firefox installed on home computers of the same users has no issues, so we can assume that the problem is in firewall restrictions. Does anybody have the same issues? What we shall do to fix them?

Only when using my Firefox in windows on my PC. After I am connected to my Gmail for a short period of time, it stops working and then I see a banner at the top that reads that it is disconnected. It will not reconnect until I close Firefox and then reopen it. I have checked everything including a uninstall and then reinstalling Firefox. Can someone help me?
