Mozilla Firefox 64-Bit Developer Edition Launches on Windows

Waltc, No need to uninstall the firefox x86 release version. Just download the 64 bit developer version. Install it. Choose default profile for x86 firefox when opening up the x86 release version and developer default profile for the developer 64 bit version when opening up the developer version.

Yep, you're right...and actually I got it backwards... By default, as you say, the browsers use separate profiles, so you can install them together. But, unless you want to redo everything relative to your x86 profile, like passwords and bookmarks (which I didn't want to do), it's better to simply share the profile of the x86 version, which you can do by simply *un*-checking the default setting in FF-64 DE. Even if you uninstall Ff x86, your profile is still there...but, you could still run them separately and use the sync-profiles feature--though I haven't tried that.

After a few days of using the x64 DE, though, I'm much less rosy about it. On many of the sites I visit suddenly I'm getting a bunch of script errors on the pages I visit (major news sites, etc.) that often crash the browser! I didn't see this much if at all in FF x86--now it is almost predictable despite the build getting updated daily. If it happens again today, I'm going to reinstall x86.

For troublemakers like Chrome, I locate the updater file and rename it (i.e. add a # to the start of the file name).

Thanks for the tip! I'll remember that if ever I'm in the mood to wrestle with Chrome again...

Have been trying both. Cyberfox does ask to download from Chrome settings etc. Waterfox did not.
Both are much faster than IE11 or Chrome.
right now my choice would be Cyberfox.

fyi ... A 64-bit version of Firefox known as Waterfox has been available for some time now. They just recently updated it to v36 to match Firefox. There's also another 64-bit version known as Cyberfox -- but I haven't used that one.

Or you can "cheat" and export bookmarks to a .json file. Also with Password Exporter extension you can export and import passwords. The .json works much better than the old export to html. I have all folders on my Bookmarks Toolbar. With backup to .json then Restore in the other browser the folders and all come out fine. No need for SyncPlaces extension anymore.

Edit: I have a few guest OS in virtual machines and using Sync to set up FF and variants gets messy very quickly. It's better just to load the bookmarks .json file etc..

Bookmarks are backed up in FF automatically. All you need to do to transfer your bookmarks to a different profile is to copy the json file form the latest backup and then restore.

Same with almost everything else - all kinds of settings, passwords, etc., are stored in particular files in your profile. Just copy those files over and it's done. No need for special add-ons to do this.
