If you select No to the UAC prompt when updating Firefox via Installer, it will install Firefox to "AppData\Local\Mozilla Firefox" without telling you, instead of overwriting the copy in Program Files or erroring out. Additionally it will create a new Profile and set this new Profile as the Default Profile without telling you. Lastly, it'll remove an existing Pinned shortcut on the Taskbar.

So you've now got 2 copies of Firefox installed, one of which you're not told anything about and an additional Firefox Profile with no indication that this happened nor any instructions on how to undo this nor how to change the default Profile.

I am trying to access certain HTTPS websites and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chromium.

Here's what I've tried (none of these works):

• DNS over HTTPS turned off
• Uninstall all add-ons
• Reinstall Firefox
• Create new profile and set it as default
• Delete/rename certs.db in the Firefox profiles folder.

The only fix that works is to use Troubleshoot Mode every time I visit these websites which is not practical. Any ideas on what could be the problem?

I don't know if this is relevant but one of the websites that does not work is https://alexan.com.ph/

Suddenly all the gmail attachments stopped to download. I can see (and scroll) the e.g. pdf in a viewing mode but I can`t download it. I turned on the troublshooting mode but the problem persisted. I can download the same attachment in Chrome.

When I search using duckduckgo within firefox I get a white page with no results sometimes, it's quite frequent and I'm not sure what is the cause. I've tried disabling addons like Ubo, malwarebytes and had no luck. I've changed my firefox settings hoping that would fix it but it hasn't. It's like the page doesn't fully load.

See subject. I do not understand computer language and am stuck. o I was working on a newsletter for a group. Now I cannot complete it.

I do not know how to connect to server I do not know how to connect to network I do not know how to check with Firefox for permission

I also cannot find the telephone numbers for my thinkpad for help.

Hi,

since it is not acceptable to use a browser that requires you to fumble around in a submenu to close tabs to the right – which is the most important tab function for professional users – I unfortunately haven't been able to use Firefox so far (which I would very much like to do for data protection reasons). Is that still the case (installing an add-on is out of the question for me)?
