Firefox 57

Just because it is Multi Process compatible, does not mean it is 100% compatible with Fx 57. It depends on how many Extensions you have like that as they will possibly slow down your browser. I would check in the new AMO to see if there are similiar extensions that are compatible, with 57.

https://addons.mozilla.org/en-US/firefox/

At some point these extensions if not made compatible will stop working.

57 version of Mozilla Firefox must be beta version because current version is Mozilla Firefox 56.

Thanks for this ...
I checked my add-ons:
- Classic Theme Restorer
- ScrapBook X
- Tab Mix Plus

These are said to be "not compatible with Quantum".
Shall I take it that "Quantum" means Firefox 57 ?

Tab Mix Plus may never work do not try to use it yet. Quantum Means Firefox 57. The 3 you have listed will break Firefox 57.

I updated Firefox as soon as I was aware of the changes coming in Quantum (57) - I upgraded to Chrome.

I started with firefox before it was Firefox but it's been slipping away for so long that I had to let it go

I was one of the first on the original SeaMonkey suite and Netscape Those heady days even pre Internet explorer, (when Bill woke up, killed longhorn and went all internet on us)

At the present Time I do not think I can mould FF57 into what I want ( I have a certain set-up I need to work with, and Chrome now gives me closer than FF)

Will obviously check it out every few months to see if it's worth giving it a try, but it seems to me that very few developers are prepared to port legacy add-ons ( or more likely the new system does not have the flexibility of the old one)

Another issue I have is that as I run a number of Android devices for mobile computing and "Life/Work Management" I have to have good inter-connectivity between Desk and Mobile,

Now MS itself, is getting better with this in the Fall Creators Update, (I can finally access my android Mail and Calendar from within the Mail app without half a dozen conversion apps), and they appear to have realised that windows phone was a dead end, and with android owning most of the mobile market, (75% of worldwide market), they appear to be looking to support it more in future

I tried Chrome once and used it for about 10 minutes. I did not like that fact that it left running processes after it was closed and even my machine was restarted. Fx 57 has multi process support as well but when you close Fx they are also closed. I have been using Firefox from Day one when it first came out as Phoenix. For a secondary browser I use SlimJet which is Chromium based.

But to each his own. I would not put it down without even trying it. You might like it.
