I have 2 laptops, one for work and one personally. I was looking to set-up firefox on my personal laptop as well but noticed I cannot open developer console on a specific element by pressing 'q' anymore after right clicking.

This is a significant feature and I would like to keep using it. Is it possible to enable this feature on my personal computer as well? Since it is still enabled on my work device.

I want to turn off the hover preview feature. First I went in settings, but that disabled only the thumbnail (browser.tabs.hoverPreview.showThumbnails in about:config is set to false and saved). Then I went in about:config and manually set browser.tabs.hoverPreview.enabled to false as well, that disables the unwanted feature completely.

But every time I restart the browser it's turned back to true (just hover.Preview.enabled, not hover.Preview.showThumbnails). Can I save my settings? It's annoying that I can't opt out.

I recently explored the backgrounds on Firefox. I choose one of the, because they look really nice. But after I changed my Firefox Data Collection and Use settings the background disappeared.

Why do you have to keep "Allow Firefox to send technical and interaction data to Mozilla" and "Allow Firefox to install and run studies" enabled?
