I run Firefox Version 10.0.2. When I follow the link to Firefox sync, I get a page that states it is no longer supported. Is Firefox sync still available? Am I running the latest version?
You are running the latest version of Firefox (10.0.2) and sync is builtin (nothing to install anymore).
However, your useragent is showing as Firefox 3.5.5...to fix do the following:
No, Sync is no longer supported for Firefox 3.5 and 3.6 versions and the Sync extension has been redrawn.
You need to update to current Firefox 10 to get full sync support.
Even though you said you are running Firefox 10.0.2 your User Agent is shown as:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:184.108.40.206) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729)
If you are in fact running Firefox 10.0.2 then see the "Other causes" section of
Websites say that Firefox is outdated or incompatible even though it's the latest version and reset
all useragent preferences from the "about:config" page.
