I have been using Xmarks for years without a single problem, so the upcoming fizzle of Xmarks prompted me to look for a replacement. I use only Firefox (Quantum), on 3 pcs and 4 laptops.
I disabled Xmarks and installed Eversync on first computer (Win10) - OK,
Then the second (WIN10) computer installation appeared to be OK.
Closed FF on the first computer, then re-opened.
WHOA!! - ALL folders EVERYWHERE were empty, plus a message " Eversync limit is exceeded (1500), so 1147 bookmarks have been trashed".
WOW!! Yes - it actually said 'trashed'
Checked the second PC - same problem!!
Went to my wife's PC (Win7), still running Xmarks and forced an Xmarks upload.
Back to my PC and did an Eversync download. All folders were OK, but there was a duplicate set of empty folders.
Same with my second PC - a forced download had the same problem.
I persisted by deleting ALL empty folders on both computers, then did a forced Eversync upload on the original PC.
I checked the second PC after a forced download, and it's OK.
Then I spent the day removing duplicate bookmarks in all folders.
Did the forced upload, then forced download on the second computer
I kept an eye on both PCs for several days, and everything appears to be OK.
Then I opened FF on my wife's PC, disabled Xmarks and installed Eversync.
I now have all three working OK, but I'm nervous about Eversync destroying bookmarks WITHOUT WARNING.
I still have four laptops to do (two on Win10, two on XP).
Eversync did uploads in 10 seconds, but downloads with the problems went for more than 2 minutes 30 seconds.
After the cleanout of my bookmarks in my first PC, there's now less than 500, and Eversync now takes about 5 to 15 seconds on a forced download.
My recommendations - clean out ANY duplicate bookmarks before installing Eversync, and keep the total below 1500 (or you may lose bookmarks, er.. have them trashed).
DO NOT, I repeat DO NOT HAVE BOTH XMARKS AND EVERSYNC RUNNING AT THE SAME TIME ON ANY BROWSER. That is guaranteed to destroy bookmarks wherever both save their bookmarks
After installation, check if your bookmarks still match those in a second PC running Xmarks, before it gets the ROOTB in May. Safety first
This is a crappy start, so though I now have a working system, Eversync needs to do something about updating the initial saving of bookmarks, rather than add more, going over its limit, and responding with a "you have more than the free Eversync will allow for, so the program is going to trash your bookmarks. If you pay $xx, you can have an unlimited list".
That sort of threat/idealogy, and poor programming, will kill Eversync.
My first impression was "EverStink", or "Neversync".
Nimbus won't like those connotations passed around if they want to take over Xmarks exalted position. DO SOMETHING ABOUT IT!!
