I installed Webroot Antivirus. Then I tried to open Outlook mail. It crashes Firefox every time.

Hello ?,
 
Welcome to the Webroot Community,
 
The Mac operating system relies on permissions for most tasks. If these permissions are incorrect, they can cause a variety of issues, both with your programs and with computer performance itself. Pleae try to follow this below.
 
To check permissions on the Mac OS:
1. Navigate to Applications > Utilities > Disk Utility.
Note: The Disk Utility feature is advanced and powerful. Any action you take using the Disk Utility is at your own risk. We recommend you only use the Disk Utility under instruction by a qualified technician.

2. Click the Hard Drive name, e.g. Macintosh HD, in the left panel.

3. Under the First Aid tab, select Show details.
4. Click Verify Disk Permissions. This operation may take some time to complete.

5. If the operation finds permissions issues, fixing them can resolve the issue you have reported. Click Repair Disk Permissions. This process may also take time to complete.

6. Once the repair process is finished, restart your computer.
 
Then check to see if Outlook still crashes in FF.
 
If you feel this is Webroot related you can submit a Support Ticket free of charge with an active subscription.
 EDIT
? I also read that you should clear your cache/history in FF and see if that works for you
Hope this helps?
 
 
KInd Regards,

Hi Again ?,
 
Would you disable your Webroot Webfilter to see if it's conflicting with Outlook? So to eliminate if it's Webroot or not.
 
Go to the Tools/Add-ons/Webroot Filtering Extension/Disable ..Then restart FF and see if Outlook still crashes?
 
 
Will you let us know if it's the Webroot Webfilter Extension or not?
 
Thanks!
