  • (2022-04-07) Moritz Kretschmer: It is more ok for an initial synchronization than in daily use as the automatic sync does not work. Combined with the fact that you cannot merge means u will for sure experience a lot of data loss. Also dropbox looses it connection after a while - which means you have to reconnect all devices again... which takes ages.
  • (2022-02-25) Gaurav Poudel: option to sync only a choosen folder would have been amazing.
  • (2021-09-24) Ben Flux: Nice work on this extension - now I can use Edge on Windows and have the same bookmarks on my Chromebook :-)
  • (2021-05-29) Karthik Girraju: Love it
  • (2021-03-24) Akki S: Hi, Extension really work as intended , no complains about that BUT: I am little worried about that extension wasn't updated for years now. Will it stay compatible/secure with feature Chrome updates? Do you guys still use this or there is alternative?
  • (2021-03-23) 하느님: 가뭄에 단비같은 최고로 유용한 확장프로그램
  • (2021-03-18) 富富: very good! … but how I can delete one or more profiles created?
  • (2021-03-15) Tempest Boya: Thank You, works beautifully
  • (2021-02-20) 天光臺灣: Unfortunately, it doesn't work for me. It can be in chrome to chrome, but it cannot be synchronized between different browsers. I have tested it on different devices, and I have invited others to test it. Maybe it’s the bookmark language problem, because it can be synchronized in a pure English environment and bookmarks. This situation has been around for many years.
  • (2020-11-12) Ben Hest: This has been a lifesaver for crossbrowser bookmark syncing. I do miss Xmarks, but this is a solid replacement.
  • (2020-11-06) Richard Yann: 太棒了,自己的书签自己存放管理,真好!正好google drive那么点儿容量也能发挥作用了
  • (2020-09-02) 自由免于恐惧的: "Failed to sync bookmark data". This error has been going on for several years and it cannot be synchronized between chrome and firefox, only between the same browser. All Chinese users I have asked have the same error. Is this because of bookmarks, browsers or non-English environment of the system?
  • (2020-08-04) Alberto: very good! ... but how I can delete one or more profiles created?
  • (2020-07-14) Pulsar Zihad: This is exactly what I wanted. Seamlessly syncing bookmark between Firefox, Chrome, Brave. So, Now I don't have to fear of loosing bookmarks. Been using for 3 months without any problem. Great work dev.
  • (2020-06-28) Julian Gen: It's ok but tends to duplicate bookmarks. So you might end up with 10 bookmarks for the same site and then have to delete 9.
  • (2020-04-03) Hey Choppi: It doesn't sync with google drive.
  • (2020-02-15) olso emoze: please make it work with Kiwi (android)
  • (2020-02-14) Faheem Ahmad: AWESOME EXTENSION, but i want it to sync FAVICONs and images automaticlly too please addd icons for bookmarks in next udpoate
  • (2020-01-16) Anonymous Wikileaks: Love it, I used the extension and wished it work fine; later my windows crashed and can't repair or login so after fresh install windows 10 and I installed back the extension and I hold my breath to see my bookmarks restore and it did. Thank you
  • (2020-01-15) Long Vo: Wonderful extension! I switched to Brave, and the built-in sync system is not working yet. This extension works great, and integrates easily with my existing Dropbox account
  • (2019-12-19) Konrad Tuschy: syncmarx is one of my most important extensions, which I use every day. When I had problems, Greg was very helpful and we were able to figure out the problem and solve it. Sometimes there are hiccups and the bookmarks double or are scattered everywhere. Then I go back to another browser that hasn't synced yet and force push / force pull to get it right again. syncmarx solves a major problem of having a self-controlled, cross-browser and cross-platform synchronization solution for bookmarks. I can't wait for version 1.0. @Greg: Thank you for an engagement, I really appreciate your time and energy.
  • (2019-11-13) P N: Allow the sync on/Permet de synchroniser sur: -Dropbox -Google drive -Box Would be cool to be able to sync locally.
  • (2019-09-20) Haixin Sui: I have tried a number of bookmark sync extension, this is the best replacement of the XMarks! It works well across platforms, firefox and Chrome on windows and Linux.
  • (2019-09-12) S R: Awesome - finally the bookmark sync I have been looking for, for more than 5 months !!
  • (2019-08-27) Ben Page: Seems really promising. Doesn't seem to work with Kiwi Browser on Android.
  • (2019-07-18) Richard Cumberland: Works in Firefox out of the box, but for some reason doesn't sync with Chrome. I haven't worked out why yet, there are no errors popping up.
  • (2019-07-18) Uwe Mueller: Very good tool to sync bookmarks in Chrome with Edge (Chromium). Miss the addin sync feature.
  • (2019-07-11) Rob Collins: I use this to sync between Chrome at work and Firefox at home. I haven't been able to get it to syn Chrome's built-in "Other bookmarks" folder with Firefox's "Other Bookmarks" -- apparently the capital B makes all the difference. My workaround was to put an "Etc." folder in the bookmarks bar and keep all the "Other" bookmarks there. "Other b/Bookmarks" remains as a non-syncing folder. Which is useless, frankly. But this extension is the opposite of useless.
  • (2019-07-08) Bobby Holla: Hi, would you please consider supporting syncmarx extension for Firefox and kiwi browser mobile. It fails to sync, force push or force pull on both mentioned browsers.
  • (2019-04-16) Ingo Korndörfer: Garbles my bookmarks, unfortunately ...
  • (2019-01-04) Paulo Sergio Soares: It is not working, I force pushed on Firefox, ok. Force pulled on Chrome, and i got "Failed to pull bookmark data". Pressing "sync" doesn't work as well. Same profile both browsers. Please help fixing, I got hope when someone said that had finally found some bm sync that works.
  • (2018-12-04) Thomas Nielsen: Not as feature rich as XMarks but considerably more stable and before all, lets me own my own data. Brilliant little tool.
  • (2018-11-27) David Eaton: This is a great replacement for XMarks. It could be a bit more intuitive, but overall very good. I sent $$ to the author, cause they deserve it.
  • (2018-10-24) Rajesh Kumar VS: Perfect! Its works fine, just started using. After long time found a perfect replacement for Xmarks... Kudos to the team behind this extension :)
  • (2018-10-12) Peter Knett: Doesn't work for me. I try to sync Google Chrome Browser with Firefox, but only "Force Push" works. 0.4.0 still doesn't work for me. "Force Push" works well. But nothing else. Update 2018-08-26: still doesn't work for me. "Force Push" works well. But nothing else. Update 2018-10-12: still doesn't work for me. "Force Push" works well. But nothing else.
  • (2018-09-12) Joseph Zimmerman: Not sure why Xmarks went away, but thanks to this, I don't need it.
  • (2018-08-30) Miguel Sousa: Great extension! I have high hopes that this can become a true replacement of xmarks. Any timelines on the new providers being added besides dropbox? Kind Regards
  • (2018-07-18) Andrew Quartararo: I forgot how I came across this, but it was definitely due to me searching for an Xmarks replacement. This has been working flawlessly since I've had installed for the past few months, and has completely passed all expectations.
  • (2018-07-12) Jason Iden: Greg, you are the MAN!! That was a very quick fix and now it is working great!! Thank you sir, for both the fix and the much needed extension. Just as a note to anyone that may read this, I originally had an issue when first attempting to use this ext. but the DEV (Greg) fixed it in less than 24hrs. Again, great ext and great DEV. Thanks again!!
  • (2018-07-10) Stephen Rowntree: Thanks Greg. The latest Alpha version is working with Vivaldi.
  • (2018-07-07) Samuel Viana: I know that this extension is in a state alpha. For me, it only managed to work on Linux. It doesn't work on Windows in either browser.
  • (2018-06-18) Chris K: All hail syncmarx! I finally found the perfect replacement for Xmarks! Suggestions: 1) Can a sync on exit of the browser be done? I have my sync set to 2mins, but I could still miss a sync. 2) Can the menu button be changed so settings are a right click, and a left simply syncs? Thanks again!
  • (2018-06-18) Bob Endicott: I really love the Extension. It works beautifully in almost every environment I have tested on (Linux Mint, Windows 7, Windows 10, Windows 2012 & 2016 for Firefox & Chrome) except Chrome on Mac. Once that is fixed I will have a complete solution.
  • (2018-06-12) Alexander Bassin: Works great for alpha. I see only one problem for both FF and Chrome. I can't set sync to 0. I prefer manual sync (Pull /Push), but every time I setting the sync time to 0 it automatically resetting to 5. Please, fix that.
  • (2018-06-04) Jonathan Guyer: Will only sync when I manually select "force Push" to dropbox. Automatic sync doesn't seem to work. Using Google Chrome on Windows 10 64bit.
  • (2018-05-19) peter a: First, thanks for this! Using BETA v030 with slimjet (chrome based) and Win10 x64. Works great, but I can't set the sync interval to 0 minutes. It defaults to 5 minutes every time. Of course, it will accept longer intervals, too. Also, how can I delete profiles? I suspect I just go to Dropbox and delete them, right?
  • (2018-05-11) R van Z.: Can't test it, site is blocked, due to falling into the gaming category.
