Incompatible With Multiprocess Rated 3 out of 5 stars

Firefox is rolling its new extension APIs and multiprocess. Please port your Chrome version over. Right now I cannot use this addon any more on Firefox with multiprocess enabled.

Very nice tool but not perfect (ONE serious bug/issue) Rated 4 out of 5 stars

I have tried Xmarks a few times over the last couple of years b/c I really wanted a way to keep all my bookmarks between various browsers and various computers in sync.

Overall I love the basic concept of how it works, the syncing, ability to login to the Xmarks site and view your bookmark histories, restore old ones, etc... (actually without those features on the Xmarks site the product would be broken for me as I will describe in a moment).

I just recently started using Xmarks again after a year or so hiatus from it hoping maybe the issues I had experienced with it before had been fixed. At first I was delighted to see the issue seemed to be no more but just today it happened again.

What exactly is the "issue"? Well when using multiple browsers, which in my case is pretty much Firefox and Chrome, one or all of the browsers bookmark settings invariably get all mangled up and hosed at some point. What I mean is it duplicates most of the bookmark folders, certain items disappear from some of the duplicated folders, others just get moved out of their folder onto the main bookmark bar, etc... I end up with a huge mess of bookmarks all over the place.

My only "fix" is to manually go in and find the correct version of bookmarks on the Xmarks site and restore it, then force a new download, causing it to overwrite the garbled mess of bookmarks I now have. Then it will be okay for a bit. The ability to do that pretty easily is the only reason the tool is viable for me. Because the garbled mess I'm talking about is bad. I mean it takes my 150 or so bookmarks I have and creates a huge mess of about 500 or so and the issue just keeps getting worse until you go in an manually restore the old correct version from within your Xmarks website account.

I think I may be onto something now though. I believe its no longer happening if I don't use the Firefox sign-in sync feature. I think somehow when you are using the Firefox sign-in to sync and/or the Chrome sign-in to keep bookmarks synched using the browser's proprietary mechanisms, the Xmarks tool is getting broken and that's what is causing all that duplication and garbled mess of bookmarks.

Hopefully this will fix it. There is no reason to be signed in to the browsers other than for syncing bookmarks and such which Xmarks can do just fine so if that fixes it permanently then I'll be happy. We'll see and I'll report back on my finding.

It if were not for this one thing I would give it 5 stars easily.

***Update 1: 9/9/16 1:23AM***
After some brief testing it does indeed appear as if my hypothesis is correct. I was able to reproduce the issue with duplicates and the garbled bookmark bar in Xmarks by having myself signed into either Firefox or Chrome. It seems to be fixed when I stay logged out of both browsers syncing features. It also seems to work if I stay logged in but turn off the feature to sync the bookmarks, tabs, etc...

Freezes your screen, prevents browsing Rated 1 out of 5 stars

It was good once. Now, it constantly runs into syncing problems and freezes, asking you to log in. Problem is, you can't if Xmarks has frozen your screen.

Now, you can no longer contact Xmarks customer support, which immediately sets alarm bells ringing, as they now fob customers off to time consuming `forums'.

Xmarks support has not changed. If you are seeing technical issues, please open a support ticket - This link is available on our support pages.

Useful tool Rated 4 out of 5 stars

Make sure you test it out while changing bookarks (sync it to see), just to get familiar with it. Has been a lifesaver. Needs much better documentation (ie. as a *.pdf).

Agree With Squeeky Rated 1 out of 5 stars

I am a premium user of both Xmarks and LastPass. I have used Xmarks since it was Foxmarks with varying degrees of success. As mentioned numerous times, for the past couple of years, XM causes intermittent hangs and periodically makes a mess of syncing. For example, last Friday's "sync" increased my bookmarks from 1,254 to more than 5,000 by endlessly duplicating unsorted bookmarks while deleting commonly used bookmarks. There may be either rhyme or reason to its insanity, but I don't have time to figure it out. I will be dropping Xmarks at renewal. Avoid the program until they (finally) have the bugs worked out. And - Xmarks people - if you can't "duplicate this error," you really aren't trying very hard...

Hi there - if you are seeing duplicate issues, this is due to you using multiple bookmark managing programs and they are automatically syncing. Please see the FAQ here -

Never once had a problem with this. Rated 5 out of 5 stars

For various reasons people seem awfully unhappy with this add ons performance.I've not had any of these happen to me even once.And I cannot recall how many years I've used this.As far as "freezing" goes this will not cause it.Check your Firefox settings.You may in fact have far to many add ons activated.Only have the ones on that you will need at the moment.If that does not work go to the support site.

Makes FF intermittently unresponsive Rated 1 out of 5 stars

I first used Foxmarks, and then Xmarks. The archived bookmarks have saved me more than once, and the syncing among several machines has been very useful.

OTOH, I have noticed for several years that FF would intermittently become unresponsive, though it would ultimately clear, before happening again perhaps 15 minutes later. My systems have fast processors, so I assumed that it was either a coding issue with FF, or that my prefs.js was "too long on the tooth" (and corrupt) after so many years and so many upgrades, or that it was a problem with one or more of my 48 extensions.

This week, I built a new system and the problem repeated (I imported my FF configuration from my main system). So, today, I spent the time to clean up my prefs.js file, and then took out my extensions one-by-one ALPHABETICALLY until I found the culprit. It is Xmarks 4.3.19. After disabling it, FF is flawless and smooth, the way it should be.

How to reproduce: Start FF, and open 10 or so web pages at one time, each in a separate tab. After 3 minutes or so, reload all of the tabs (this step probably isn't necessary). Now open Task Manager (so you can watch the FF CPU usage), and wait. First, the FF usage will drop to almost 0; then it will build, before dropping slightly again, and finally it will build and hold (in my case ~38%; Win7 with an i7-920 CPU, and Win10 with a i5-3320M CPU), and FF will become completely non-responding. This will take less than 5 minutes. If you wait, it will clear in a minute or so, though it will periodically freeze on a regular basis.

As much as I love Xmarks, I am absolutely thrilled to be rid of the problem. I could have given XMarks 5 stars for many reasons, but since it chokes my system and my user experience, I give it 1 (0, my preference, not being an option).

Useful only once and Irritating Rated 1 out of 5 stars

Tool is useful only for one initial sync and nothing else. It creates a bunch of duplicates during regular work. Avoid using it for continuous syncing at all costs. It is like this for years. None of the so called "tips n tricks" will make issues solved. I wasted a bunch of my life (daily )on manually restoring Bookmarks Sets and garbage cleanup, and reading manuals and resting settings.

useful if you format your PC Rated 5 out of 5 stars

everytime I format my PC, I use it to restore all the bookmarks and history. Also it syncs between my PC-home and PC-Word

It Does What Now? Rated 1 out of 5 stars

It does not sync.

Installed it on Chrome and Firefox. It could not sync with either one. It would not accept the password on Firefox (fine on Chrome). I reset my password (to the same password) and it worked on Firefox. Then it kept freezing up Chrome. Uninstalled it on both.

I cannot recommend this extension.

All useful features pay only Rated 1 out of 5 stars

The only reason someone would use this addon would be to synchronize bookmarks from their preferred desktop browser to their preferred mobile one. That feature is pay only.

There are other apps for synchronizing desktop browsers, all of which are free. This addon is complete useless.

Used to be a great add on Rated 1 out of 5 stars

Recently bookmarks dont sync, even when choosing to overwrite local data. Hope they can fix it.

Sorry about that! Could you please provide more details and send us the debug log to us: so we can assist you further? Thanks!

Really buggy Rated 3 out of 5 stars

Great addon, but muddles my bookmarks up every couple of days. Folders tend to disappear and I'm forced to restore old backups.
This last part is hard because the site tend to be really slow or never fully load at all!
