Trusteer Endpoint Protection no longer showing in extensions, although installed on PC and working on Chrome

more options

I have v75.0 installed on my PC. When refreshing Firefox previously, Trusteer Rapport was always disabled but I could enable it again by choosing the option in extensions. Now the trusteer icon does not appear in the address bar and the extension is not shown in add-ons, although the IBM app shows it is working and it's fine in Chrome. Any help would be much appreciated thanks.

The issue should have been present in Firefox 74 when the situation the "sideloading" of extensions was modified. Extension / Add-on developers may have to change the manner in which they provide Firefox extensions. Firefox 74-plus no longer searches the hard drive to look for those types of extensions; where previously Firefox would "see it" and automatically use it & display it in the Extensions Manager, which was changed to automatically disabling it at some Firefox version in the past. Now the "security" has been pushed up a notch, the user has to specifically install the extension via the XPI file method.

One thing that still works is to "manually" install the extension XPI file once the user downloads & saves the XPI to their computer. Then while Firefox is open the user drags the XPI into the Firefox browser window to do a manual extension. That should work with Trusteer Rapport, BUT you need to find the XPI file to be able to proceed.

I just want Mozilla to fix it so that I get the option to enable Rapport, just like before.
