Problem type: Something else
Description: Previous Firefox versions used to open my site, created with Robohelp, correctly. Now, the left-most pane that should open with a list of content links is empty. Edge browser opens the site correctly, and Brave browser also opens the site correctly. Any possibility something can be tweaked? Thank you all very much for your work, excellent products, and time reading this.
Steps to Reproduce:
Previous versions of Firefox going back many years used to open my website correctly. Recent Firefox versions do not open the site correctly. In the left-hand pane of the site, there is supposed to appear a list of content links to the pages of the site. Firefox does not display the content links anymore, but the pane does appear. On the other hand, the site operates correctly in Chrome and Brave browsers.
