It's the same with me, I have a robust configuration, but it's a little slow compared to Chrome.For me, it is still a very poor and slow performance when opening web pages, compared to Chrome and Opera, Firefox is very slow. I really like Mozila, but on my system it doesn't work, obliged to uninstall
I agree that sites like Flickr can be slow loading on FF, but it doesn't seem much different when using other browsers. We're at the end of the line as it were, on the coast and lots of our traffic comes via another nearby coastal town, we felt that was more of a reason for why it seemed slow here rather than the type of device or software we were using. FF bookmarks, downloads and history are what I've got used to over the last 15 years, it may be that I don't want to learn new tricks as far as they're concerned, but I do like the way they work better than other browsers means of handling themI find Firefox on Windows rather slow on image-heavy sites, but I have a cheaper i3 laptop and use a lot of add-ons. I still prefer FF to any Chromium-based browser because of its better management of bookmarks and downloads.
The fastest browser I have ever used is Slimjet, but it's based on an always slightly outdated version of Chromium. Firefox w/ only 3 add-ons on my 2017 Android tablet is so slow as to be unusable, so I mainly use Kiwi Browser on mobile these days.
Now why am I not surprised that G**gle/YouTube have done something that potentially leads to messing up anti-fingerprinting techniques?!If you have any problem with YouTube borked here's the links:
Firefox users have recently started to notice that YouTube does not display videos properly when they enable the browser's anti-fingerprinting technology for better privacy.www.bleepingcomputer.com
thats problem for FF 72 and 75.0 its about Google (YT) not Mozilla
