I think this feature is important enough for me to consider switching this time.
That being said, I admit that staright out of the box Firefox doesn't have the same experience but you can customize every little thing about it to make it suit your needs.
This said, I honestly don’t understand what people mean when they say the experience is “superior” in Chrome. It’s a web browser. It browses. You get passwords saved and synchronised. Everything else is an extension. What’s so bad about FF...?
I just could not live without firefox and being unable to share tabs/links from anywhere in my phone to my desktop and or laptop
I hate the hell out of that. My phone is my phone, my laptop is my laptop, just leave them alone.
It also felt noticeably slower at the time.
Finally, with Chrome's market share, good extensions that Just Work are more common there, in my experience. I use a whole host of plugins on desktop, and when I looked at switching back to FF last year, I did not find equivalents for everything.
I did go back to FF on mobile, because I do remember the nightmare of IE 6 and want to protect the web from total Google control. On mobile, I miss the dev tools and array of extensions less.
As for bookmark, firefox should be able to import chrome bookmark. It can even import saved passwords and cookies so your active session is preserved.
