I'm trying to install Mozilla VPN but it won't install. The error message is as follows: the installer encountered an error that caused the installation to fail.

Hi everyone,

I’m Ajay Hinduja From Geneva, Switzerland. How can I resolve installation errors and ensure automatic updates work correctly in the latest version of Mozilla Firefox?

Thanks in advance! Ajay Hinduja Geneva, Switzerland (Swiss)

I'm an IT support professional and in our environment we are still running few servers (for multiple reasons) with OS version Microsoft Windows Server 2012 R2 Standard and Microsoft Windows Server 2012 R2 Datacenter and they have currently Mozilla Firefox ESR (x64 en-US) 115.15.0 installed. I couldn't find any clear answer, hence I've created this ticket - is Mozilla Firefox ESR 115.16.0 supported on this OS ? - usually you are not referring to Microsoft Windows Server in you release notes info - f.ex. https://www.mozilla.org/en-US/firefox/115.16.1/system-requirements/ so I need clear answer. Also I cannot download Mozilla Firefox 115.16.1 from https://www.mozilla.org/en-US/firefox/115.16.1/releasenotes/ - if I click download it always downloads Mozilla Firefox 128 instead. So please let me know if there is any Mozilla supported version for Microsoft Windows Server 2012. Best Regards, Milosz Wrzalek

I have 2 almost identical Windows 11 Pro 64 bit machines but Firefox is different One has MSIX-1.0 and doesn't update while the other has Firefox 141.0.3 and updates regularly!!!

I don't like the MSIX-1.0 version and want both machines to use Firefox 141.0.3

How do I fix??? Best regards

I have loved FF desktop browser since I started using it per my boss in 2003. But I am so tired of the fact that EVERY SINGLE TIME you put out an update it breaks my access to the bank. EVERY SINGLE TIME. I waste HOURS reading articles, calling the bank IT dept, chatting with people who are on 3 calls at once, only to hear them tell me to "just use chrome." I clear the cookies, clear the cache, reboot, follow all the prompts in the settings and THEN the damned bank server doesn't recognize the device so it forces yet ANOTHER password change. It happened again TODAY and it makes me so sad but I cannot do it anymore. I am STILL now (going on 4 hours) trying to access the billpay page @ Xantanderbank. (ahem, secure codename) I am forced now, by this craziness, to use the imbecilic duckduckgo which is A) and offensive name and b) you KNOW it nowhere near the product you have built but I CANNOT DO THIS ANYMORE. Thank you for the time it takes to read this diatribe. I appreciate it.

On the latest update to firefox, the browser now has a vetical tab in addition to the horizontal ones. I want to remove the vertical tabs, and ideally for it to never come back. I've searched the settings as well as the support features and can't find a way to turn it off. I am legitimately not going to use firefox at all until this issue is resolved.

Thanks

I installed chatgpt, but I've found it more of a nuisance than a help. I've tried on-line to find out how to remove it but none of the suggestions seemed to work. I'm using the latest version of firefox on a Macbook Pro. Any ideas welcome. Charlie

I cannot login into a website because they complain that I have an old version of PHP. Is that already included in Firefox? I am using Firefox Vers. 143.0.4 on a MacBook Air with MacOS Big Sur, Vers. 11.7.10 Shall I go to the PHP website and download PHP?

Hi ! I'm a long term user of the "Firefox" browser. My Firefox User Nº is : 14634487 I'm also an existing long term user of both "NordVPN" and "NordPass".

When logging in to "Nordpass" this morning on my (new) MacBook Pro, I received a message in the App window stating that they were "ending support for my extension on 30th of September" and inviting me to "get the latest extension to continue using NordPass in a browser"

So, I bought a 2 year subscription for the extension 'NordPass Premium for Firefox'. Nordpass has acknowledged this by email: Quote : "Thank you for your purchase Here are the details of your order. Item  : NordPass: 2-year subscription Price : £29.43/2 years VAT 20% - £5.89 Total: £35.32/2 years"

In a 'Welcome' email sent by NordPass, I clicked on "Download NordPass which opened a Firefox 'Add-Ons' web-page for downloading the app named "NordPass Password Manager and Digital Vault" - but the only functioning button was 'REMOVE' ! I tried to 'Log In' at the top right corner of the page but I then became stuck in a continuous loop of picture identifications to prove I was not a robot ! It just went on and on ! I abandoned it for a while and, when I returned, the 'Robot check was gone but all my attempts to get the extension have failed ! I can't for the life of me find ANY means of downloading and installing the extension I've PAID FOR !

Whether this is all owing to a fault on the "NordPass" side or in the "Firefox" browser side is a mystery to me. Either way, I'm sending this message to BOTH.

I've now given up trying to do it unaided. PLEASE, could someone advise me how I can get my extension !! If this isn't resolved quickly, I'll seek to have a refund of my £35.32 and will have seriously to consider leaving both "NordVPN" and "NordPass" and/or defecting from "Firefox" to the "Safari" browser.

I'm waiting eagerly to get this sorted. Regards, Ivor Mitackis

We are in an enterprise environment and for years we have had disabled automatic updates.

Firefox ESR 128.2.0 has been deployed with defaults and these settings have been configured to override previous settings.

Computer Configuration > Administrative Templates > Mozilla > Firefox

- Custom Update URL = Disabled
- Disable Update = Disable
- Application Autoupdate = Enabled
- Background updater = Enabled

We also have a system proxy configured.

Updates do work if someone goes to Help > About Firefox.

Looks like the update interval is once every 7 hours but how is this triggered?

When I custom installed to a different path,I didn't have the service installed,and when I encountered an update,I manually updated and restarted Firefox Brower,and I saw two uninstall lists in the control panel uninstall list.
