Hi guys, I tell you the story of one day that I'll mark with a black cross on my calendar. I run firefox 68 on a mobile device under android. Well I had 100+ tabs open and remarked that firefox was devastating my battery. Thus I searched an add-on to manage the session and save the tabs for later use. The add-on I have installed has wiped out ALL tabs beyond recovery. The sync function doesn't help here because of a random reliability. So I tried to recover some data through the browsing history. On a mobile device FF limits the accessible history pages you may access directly, why? I am clueless. One way to retrieve datais by entering 3 letters in the search bar such as "man" and access all the manuals you have been searching for in the last months. A tedious work. So, I decided to install an add-on that would better access and handle the history that FF does. Thus historyfy. As a first measure historyfy DELETED ALL my browsing history....Voila my tabs and my history gone forever. Last but not least, historyfy doesn't display anything!
That is how two add-on ruined my day.
