Seems like the tabs take up more space than they used to..
Anyone else notice that? If not it could be a Linux thing..
Not sure I care for the appearance changes at all.
Supposed to be faster, maybe it is a bit.

yes, there are some "updates"... We are still getting used to these updates.

IMO lots of changes, as if I can handle these well at this time as
I try to recover my computer skills. sigh

Out of curiosity I installed it a few days ago. Importing bookmarks and passwords from Chrome was easy.

My initial impression, after some experimenting, is that it is faster than older versions (running under Windows 10 on a high-end laptop) but nothing startling compared to Chrome.

I will keep experimenting and, depending, will probably keep both it and Chrome.

OK, after some more experiments, here are my thoughts on the differences between the latest version of FF and Chrome - make of them what you will.

(1) Without doing a formal bench-mark, the speeds of both are similar.

(2) The recommended FF adblocker (uBlock Origin) works well.

(3) FF coped well with my two "high-security" sites - Internet banking and doing my tax return on-line.

(4) I prefer the Chrome layout of bookmarks (top of the screen) to the FF versions (left or right of the screen). Not a big issue.

(5) I dislike the FF response when I open a new tab, which I only do to start a new search. In Chrome that takes me to an uncluttered screen where I can type in the keywords. In FF it is very cluttered - a whole bunch of irrelevant stuff.
