Firefox Support Forum

With security concerns on the rise, our company has required that all software installed on their systems go through an approval process.

As part of that approval process, they want to know the following:

• Is the software signed by a trusted third party?
• Is the software downloaded from a US hosted facility?
• Does the software perform call backs to the software maker?

Thank you!

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?

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?

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 Currently, Firefox, Prompts end users if they want to update which is normaly dismissed and the instance remains outdated.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.

A few weeks ago, Firefox stopped working on my machine. When I tried to launch it I got an error message "Firefox has stopped working". I tried a reinstall and a clean reinstall but both installation procedures fail with the same error.

I'm running Windows 10 64-bit. I am installing with administrative permissions.

There are two files in AppData\Roaming\Mozilla\Firefox\Crash Reports from the two days that I tried reinstalling. I'm not sure what to do with them.

• InstallTime20201027185343 (from today)
• InstallTime20201014125134 (from my last attempt, on 10/22)

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

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

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?

at work we use a proxy network with authentication ONLY with the firefox browser i have proxy problems. I see the page access denied by the proxy server, the only solution is to close and open the application.

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,
