Hello johnvemery88,

Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove your Firefox program files and then reinstall Firefox. This process does not remove your Firefox profile data (such as bookmarks and passwords), since that information is stored in a different location.

To do a clean reinstall of Firefox, please follow these steps: Note: You might want to print these steps or view them in another browser.

1. Download the latest Desktop version of Firefox from mozilla.org (or choose the download for your operating system and language from this page) and save the setup file to your computer.
2. After the download finishes, close Firefox.
3. Windows: Click the Firefox menu , then click "Exit".
4. Delete the Firefox installation folder, which is located in one of these locations, by default:
5. Windows: (Note: Check both folders.)
   • C:\Program Files\Mozilla Firefox
   • C:\Program Files (x86)\Mozilla Firefox.
6. Now, go ahead and reinstall Firefox:
   1. Double-click the downloaded installation file and go through the steps of the installation wizard.
   2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

More information about reinstalling Firefox can be found here.

WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See Back up and restore information in Firefox profiles.

It also could be possible that there is a firewall installed that blocks some internet addresses by Google. In that case, you should try to disable the firewall.

Please report back to say if this helped you!

Otherwise, please contact your IT department.

Thank you.

That's a company computer and they decide what you can and can't do to it. Users here can't circumvent company policies. Use your own computer for personal Gmail and youtube activities.

Dropa,

I am not asking to circumvent any company policies. As I stated in my question, I was told directly by IT that no policies restrict the usage of Firefox, Gmail, Youtube, or any other site. Additionally, we use the Gsuite for company emails, so this isn't just about browsing my personal email. I literally can't access my work email via Firefox anymore.

This could be a problem with the TLS 1.3 Early Data feature also known as Zero Round Trip Time Resumption (0rtt). You can try to set security.tls.enable_0rtt_data = false on the about:config page to disable this feature until this is fixed by Google or Mozilla to see if that helps.

Thanks for your thoughtful reply. Unfortunately, this didn't seem to help my situation, but hopefully it will prove helpful for others who find themselves in a similar situation.
