Forum d’assistance Firefox

I have a SonicWall firewall on our office network. I can log into it from an office workstation, but when I try to export/save its Configuration I get the "Secure Connection Failed" message. I've searched for a solution to this but have only turned up two:

1) Disabling SSL Scanning Feature in Your Antivirus Software.

2) By Changing the SSL Settings On Firefox

Neither of these are desirable. For option 1, this computer is using Windows Defender, and disabling SSL scanning is not a feature that I know of. In either case, these solutions are across-the-board and would affect all pages I go to whereas the only one I'd like to get to is this SonicWall device located on our internal LAN.

I recall that Firefox used to allow you to make an exception on a per-site basis. Is this no longer possible? Is there any other way to accomplish this without disabling SSL validation for all sites?

AdBlock Plus extension does not work after updating Firefox (to version 102.3.Oesr) on desktop MacPro. Deleting the preference file (pref.js) has made no difference.

This problem has not occurred after updating Firefox on my laptop Mac Book Pro.

Both computer use OS High Sierra (10.13.6).

Please advise. Thank you.

Since I updated to FF91, I'm seeing 11 - 18 FF images in the task manager. What has happened, should I be concerned and do I need to get more memory. I currently have 6G running Windows 7?

The spacebar does not produce a space between words, when typing text. I'm using an iMac on macOS Monterey (V 12.6), and a Mac keyboard. It also causes the window I'm writing in to expand and contract in size. This happens when typing emails also. What do you recommend?

For some reason, many homepages looks wrong when I'm using firefox from my laptop (mac). I don't know why and can't find any ways to make it better. Can anyone help me?
