Firefox and AVG compatibility

Good day,

The only thing that works from what I have tried is disabling the webshield which for some reason I don't have to do with Internet Explorer and Chrome.

Hello Georges,
We will look into it.
Please provide us the screenshot of that error message to check with it.
Please try to disable each components https://support.avg.com/SupportArticleView?urlname=Disable-AVG-Antivirus and check which component fixes the issue when disabled.

Did that. So far so good. Seems to have resolved the issue. Thanks for your help.

Good day everyone,

When I try to send email using Outlook web from the Firefox browser, I often get a failed to send error message. When I deactivate AVG I'm once again able to send a message. This doesn't happen when I use other browsers like Chrome or Internet explorer. There seems to be a compatibility issue with Firefox. Anyway around this? Thanks.

Thank you for sharing us the screenshots, Georges.
This isn't the usual behavior. In this regard, we may need to identify the component that causes the issue. To do so : Open AVG - Menu - Settings - Basic protection - Disable File Shield - Check the issue - If issue persists, re-enable file shield & repeat the same steps with other components. 
Also, let us know if you're using AVG Free Antivirus or Internet Security along it's version (Open AVG - Menu - About) & Firefox, as well.

Thank you for updating the status, Georges.
If the issue occurs again, do inform us immediately.

I'm using the free version. I will try what you suggested and see what works. Thanks.
