Clip to Devon Think Extension in Safari Keeps Disappearing

[ethanw6258]

I am currently running DEVONthink 4.1.1, Tahoe and Safari 26.2. The Clip To DEVONthink extension in Safari keeps disappearing from my installed extensions and is not available. Closing Safari, re-installing DEVONthink, then opening Safari re-installs the extension and once enabled it works fine for several days, then disappears again. I have work-arounds but this is becoming frustrating. I believe this all started when I upgraded to Tahoe, but I am not sure exactly when. I have not installed any new apps or extensions that should interfere with this. Any thoughts about why this happens and how to fix it? All other aspects of DT work as they are supposed to. It would be a major nuisance for me to switch to Firefox where the Clip to DEVONthink extension seems more stable, so that is not an option for me.

It’s a good idea to search the forum. There is an extensive thread here:

Reinstall Safari Extension

Good morning, The Safari Extension disappeared from the Extensions panel after upgrading to MacOS 26. After investigations, the permission had not been given to DEVONthink in the Privacy & Security > Automation setting. I have fixed that now, but the DT Extension is not appearing in the extension panel. How might I reinstall the extension? If I have to reinstall DT4, how do I preserve my databases and settings?

And a more recent one here:

DT4 Web Clipper Has Legged It

I have recently updated (I use the prefix “up” to denote direction rather than improvement) to Tahoe 26.2 on my Macbook Air M2. Now my DT4 web clipper (which, since DT4 arrived, has made somewhat intermittent appearances anyway) has completely vanished for good. I cannot find it in Safari Extensions, it does not appear in extensions list anymore and does not seem to be in the “Get More Safari Extensions … “ Has anyone else experienced this behaviour? I would like it back. I do not use any o…

Thanks. Did search first but did not use the exact terms “clipper” and “safari extension”. I used “clip to DEVONthink” and variations thereof with or without “extension” in there. Anyway, at least it’s good to know this is not a problem unique to me. The re-install fix has worked for me recently but it is not worth the effort - there are other ways to capture the information from Safari. I guess I will just wait until Devon software engineers fix it with or (probably) without help from Apple.

This happens in just the same way for me, and it’s a massive inconvenience. I hope it gets fixed soon.

kinda up to Apple, sadly. Read the threads here.

I was hoping the 4.2 release would have addressed this issue but I can confirm that it is still happening. That said I’ve gotten used to running the terminal command to restore:

pluginkit -a “/Applications/DEVONthink.app/Contents/PlugIns/Clip to DEVONthink.appex”
pluginkit -e use -i com.devon-technologies.think.clipper

I tried that script and it worked the first time. So nicely, in fact, that I created a shortcut closing the two apps, running the script then opening the two apps in the right sequence. After I did that, it never worked again. I have to re-install DT each time. I’ve (reluctantly) learned to live without it. Disappointed to hear that it wasn’t fixed.

There is nothing in the release notes indicating it is fixed.

I have to re-install DT each time.

No you don’t. As I’ve already mentioned several times, the browser extension is not required. In fact, I have pointed many people to set a hotkey in the Sorter preferences and they have all agreed it feels much faster to clip now.
