Firefox Community Forum

when I tried to install an app that I downloaded from Wacom a prompt came up and said that "Install Wacom Tablet.pkg" can't be op;ened because it is from an unidentified developer. What do I have to do to open the app?

I'm taking an online course using Canvas, and there is an Immersive Reader option that I'd like to have available. How do I activate the reader using the Firefox web browser?

trying to upgrade my firefox browser which isn't working for important things - downloading it for my linox only went to my download folder not upgraded - so trying this - Paul - BandOfLife@gmail.com - help thanks April 25 25

Firefox closed the browser for an automatic update two days ago, and when it came up back after the update all my open windows and tabs simply disappeared. History tab was reset to a blank page, there was no trace of anything. I tried the access through 'Menu / History / Recently closed windows' or '.../ Recently closed tabs' and they were both blank, empty, zero, nada ... This is the first time it happens to me, and I'm surprised and disappointed that such a predictable and basic bug shows up on an update.

I have a couple dozen tabs I use for task f-ups, it' unproductive and annoying to get them all back up to work. If this happens again I doubt I keep using Firefox as my preferred browser.

1. Anybody else suffering the same issue?
2. Is there a cure for the problem?
