Do you leave Chrome running all the time? Yes, of course.
Do you leave Firefox running all the time? Yes, of course.

I don't even turn off the laptop, I just put it to sleep.
The application was also quit during operation as recommended.

P.S. I would like to ask, am I really the only one whose synchronization doesn't work? If so, that's very strange.

After a few days of testing, trying and terminating the free license, I unfortunately cancelled the installation of the latest version of BookMacster. The level of functionality is very low. Despite following the rules and recommendations, there is still an unreliable transfer of bookmarks on one laptop between Collection, Safari, Firefox and especially Chrome (in the case of Chrome, BkmxAgent keeps dropping out). I use a standard macOS installation and always the latest versions of the browsers.
Relatively good results are perhaps only between Safari-Firefox.

I regret this because this is an application I really need

The question whether it makes sense to test Synkmark yet whether the synchronization would not behave better?

1. a) Yes you are right, I meant "extension".
b) Yes, the test is now successful but in the past days the obšas reported an error.

2. OK, I understand that the extension icon may be greyed out. Of course the "BookMacster Sync" card in Chrome's Extensions window is colored.

I tried to follow your help https://sheepsystems.com/files/support_articles/bkmx/browser-ext-fails.html.

a) In the case of the first point of the Developer mode Chrome help, the image matches my condition.
b) After typing "ps -alxww | grep Chromess | grep -v grep", sometimes it shows that both agents (Firefox, Chrome) are active but sometimes the Chrome agent is missing.
I haven't gotten to the next testing point yet.

However, even if I follow the recommendation to quit BookMacster during operation and wait longer than a few minutes before opening other browsers, sometimes changes between Safari and Firefox still don't transfer (even to Collection).

I'm not in IT and also unfortunately don't have enough time to debug a program for several days. I assumed that the application should work in the base although I understand that sometimes the problem can occur. I'll try to give it a few more days before the free license expires.

Thank you for your help

Hello Jerry,

Unfortunately, I have indeed repeatedly reinstalled the agent just as you describe.
The BkmxAgent is of course set to full disk access. In Firefox, the agent behaves correctly.

Thanks

Reinstalling the agent didn't help.
