Firefox Support Forum

So, despite selecting "Allow Audio and Video" in the Site Preferences, "AUTOPLAY BLOCKED" continues to show on a tab, and it only goes away once I access the tab. This particularly happens on Youtube media.

You may find attached to this question an image of my about:config settings.

What further can be done to fix this?

A few days ago I opened my monitor and was greeted by Firefox, already open, with the session erased. No clue how or why.

I found this thread [restore firefox session]. Very helpful.

I solved the problem by copying the latest upgrade.jsonlz4 file in the sessionstore-backups folder, renaming the copy as sessionstore.lsonlz4, renamed the original to sessionstoreold.jsonlz4, and replaced it with the copy in the main profile foider. It worked fine.

The only problem was the backup file was 2-3 days old, so there is a disparity between the content of the latest erased session, and the tabs from the backup.

I'm confused why there wouldn't be a backup created whenever the browser is closed, or something to that effect.

Is there no way to increase the frequency of created backups, and the quantity of of theses backups?

I am not a programmer. Just tell me the path >, >, >... how to find my past sessions so I can restore them. I am using Linux and most recent version of FF, no windoze. I openend a few tabs since so History recovery doesn't seem to work. This is such a critical tool, why not just have a button to do this? Why make us hunt & peck every time?

I played same Youtube video on Firefox and on Edge and Firefox uses way more data(I/O write bytes) I/O writes and I/O Read bytes than Edge. I added the screenshot.

pm: I ran Firefox in Safe mode and with Sessionstore disabled . Some say it is because of History, but I dont want to delete it.

When I try to open new tab in browser , it auto closes when I type URL or click a link. It doesn't happen all the time but its happening and its kinda annoying. It happens like 3/10 times.
