The Vanguard website warns me that my Firefox browser "is no longer supported" and must be updated. when I try to update, the message is "Firefox is being updated by another instance." what does "another instance" mean? how can I update it? fyi I run Windows 11 on my desktop.

can you help? Firefox was updating my machine. As I remember it asked if I wanted to add  ??( I don't know) Android  ????? I didn't think I wanted it so I thought it was over and I stopped. Now I can't get Firefox -- can you help me?

For past few weeks, Whenever I try to update FFX on windows 11, it fails. It takes me to another screen and tells me to download Firefox. When I try to download it , it aborts with this message.

"download.mozilla.org has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site."

To download Firefox with new version I have to use another browser but no choice. Then with new version of Firefox, I have faced the same issue of update and used same approach to update firefox to a newer version.

This error appears for some google sites as well but the same occurring for firefox download site itself is not understood.

I have taken the position of never installing updates of firefox in windows 10 because of the following: after EVERY update, within 20 minutes of activity my mouse freezes. Keyboard is inactive. I have no option but to reboot. Windows displays "repair mode" 2 HOURS LATER ! the pc finally boots. This happens after EVERY upgrade. Since I have stopped upgrading, the pc behaves.

HERE'S HOW I SOLVED THIS "SECURE CONNECTION FAILED" ISSUE:

Kept getting this error when attempting to update Firefox; didn't matter which browser I used; went through the forum postings and tried every this-and-that-and-this-and-that posted there; didn't work; finally --

i opened a $10.00 30-day hotspot account with Xfinity, and the download worked perfectly.

PROBLEM SOLVED.

I’ve been using version 68.12.0 for a long time and now want to update to a newer version. Since I have many important tabs saved, I’d prefer not to uninstall and reinstall the app to perform the update. However, when I tried updating to versions like 80.1.2 or 110.0.1 from the Google Play Store or GitHub, the installation failed, and my phone displayed an "App not installed" error.

Could you advise which version I should install to successfully upgrade from 68.12.0? Alternatively, if there’s a way to export or back up the tabs in this version, that would also solve my problem—though I haven’t found a method to do so for this specific version.

have no idea what this topic falls under but getting the update browser error code 99,999 again after restarting the damn computer when it just froze while I went out for 15mins I am updated so have no clue what to do

wish sending a question or replying to the email was easy but even that is b/s also this deny person claims bug fixed but obviously not
