I have read every article on this I can find, including everything in Firefox. I cannot get videos to stop automatically play. I can get them to not play sound. I have changed every single setting in about:config, media.autoplay. Nothing stops them from playing. I have used numbers from 0 to 5 in media.autoplay.default. Attached is a screenshot of my settings.

I do not have any plug-ins at this point, as I just installed Windows 10 and am configuring my computer.

I am extremely sensitive to these moving videos; they make me feel sick. So I really need them disabled. PCMag is a good example of a site with a million different (types?) of videos playing.

Since updating to Firefox 70, the tab bar is shown even if there is only one tab (it just shows the + button then). Previously, the bar was hidden if there was only one tab. This previous behavior may depend on some setting, but I don't remember if I changed any setting for that. Have *no* Add-ons installed that affect tab visibility.

How to restore the old behaviour that tab bar is hidden if there is only one tab?

I often need to reposition windows so I can see enough of several to click between them. When I move a window so it touches the edge of the screen, it switches to full screen. How do I turn this function off so that it will not become full screen unless I explicitly choose that option from the fullscreen/restore button or a menu option inside Firefox.

YouTube HTML5 1080p@60fps videos in full screen are choppy, independently if the hardware acceleration is turned on or off. I've tried clean profile, I've tried these methods: https://old.reddit.com/r/firefox/comments/amy7j6/its_been_years_since_firefox_has_stutters_on/efpuhc5/ Nothing works. How can I fix this?

That is not a hardware issue - I have no problems with watching 1440p@60fps videos in chromium.

Recently I've been having trouble with the dropdown menus in Firefox, such as the History and Bookmarks menu in the tool bar and the right-click menu. Intermittently when I open the menus they close within a second or two without me doing anything. This only happens in the Firefox window, all of my other apps and browsers are fine.

I'm running on a Macbook Pro with OSX 10.15.1 and Firefox 70.0.1. I've restarted Firefox and it fixes the problem for a short time then the problem returns. I've cleared my History, including Caches and Cookies, reinstalled Firefox, restarted my computer and tried disabling my add-ons. The issue keeps coming back.

I was force updated to Firefox 70 and I didn't like the new layout for the new tab page, so I installed the .exe to downgrade to 69.0.3 .

However, when I launched Firefox again, I lost all of my saved data on the browser and it was a fresh profile.

Prior to downgrading, I had saved a copy of the Mozilla Firefox folder that is C:\Program Files\Mozilla Firefox just in case.

Is there any way I could fix this and revert to the saved settings, extensions, and passwords that I previously had?

Thank you in advance.

The Firefox Home page does not properly resize content to fit the window size. I have had this issue for a while on my laptop, but it just started to happen on my desktop also with the 70.0 update. I posted about it on reddit a while back to try and find help, but no one was able to give me any. Here are some screenshots of the issue on mac from that original post https://imgur.com/a/vTlXfmJ I just want to know if there is any solution to this issue or if anyone else is reporting it. I haven't been able to find any other posts about it and got basically no response from the reddit.
