Recent convert from Xmarks. ES seemed to work well until recent update. Have these issues now:

- Extension update disabled bookmark auto-sync ; had to re-enable after realizing the change
- "Manual Sync" options don't actually have a manual *sync* button ; is a true manual sync reserved for paying customers? Can only *merge* local/server data (which doesn't *sync*), or up/download data which are 1-way overwrites

UPDATE:
- Just found that when Eversync options page is open (not taking any action), Firefox CPU goes to ~13% until options page is closed. Wow.
- No prompt to verify manual download ; only to upload
- "Enable auto sync" option keeps becoming disabled

Time to look for yet another cross-browser bookmark sync tool...

UPDATE 2:
Review has been flagged. Apparently can't handle the truth?
