Created attachment 8643450 [details] xl_plugin_firefox.xpi The extension has |gContextMenu=new nsContextMenu(this, window.getBrowser())| in its code. nsContextMenu was changed in https://bugzil.la/782850 , causing Fx to treat any right click as shift + right click, preventing HTML5 context menu to be shown. Beijing office reached out to Thunder, but we were told this extension was no longer maintained. Please consider block it on Fx 21 and above.
Added to compat override list.
