Tampermonkey suddenly stopped working.

[DeltaStruct]

Tampermonkey suddenly stopped working.
I also tried disabling Tampermonkey and restarting the browser, but nothing changed.
I would like to see a list of user scripts installed if they are difficult to recover.

Expected Behavior

Actual Behavior

All script not working.
When I open options.html, it says that an internal error has occurred.

Specifications

• Google Chrome: 127.0.6533.72
• TM: (i.e. 4.5.5648) idk what this is sorry...
• OS: Debian 12.6 (KDE Plasma 5.27.5)

Script

(Please give an example of the script if applicable.)

[derjanb]

Please open the developer tools (ctrl+shift+j). Does the console tab show any errors?

[DeltaStruct]

No errors were shown.

[DeltaStruct]

Sorry, I closed it by mistake.

[derjanb]

Ok, then please open a tab and paste this URL: chrome://extensions/?id=dhdgffkkebhmkfjojejmpbldmpobfkfo. Find the "service worker" entry at "Inspect views" and click it. Do you see errors at this console tab?

[DeltaStruct]

In "Inspect views" only background.html was found. There I see an error.

[derjanb]

The first issue is that chrome.storage.session is not available even though it should. The next issues is that probably the indexedDB in the browser profile folder is broken.

Can you please try a new temporary profile?

[DeltaStruct]

I tried it with a new profile and it worked.

"Service Worker" also exists.

我在win10使用Chrome也是同样的问题

Same here: suddenly stop working on Chrome while working in FF.

Same here: stopped working in Google Chrome. Userscript is not shown anymore as active for a given url. Works with Firefox. I tried w/o success:

• new google chrome profile
• switching extensions to developer mode ( as mentioned here )

Under Extensions I get told that Tampermonkey ( among others ) is an extension possibly not supported anymore.

[homes410]

Here's workaround for those who are witnessing this problem, Start Chrome with --disable-renderer-backgrounding appended to its command argument. Any extension process of Chrome is started as lowest priority so if you have high-load tabs, Tampermonkey extension would become sluggish, for now this is only way.

Ok, then please open a tab and paste this URL: chrome://extensions/?id=dhdgffkkebhmkfjojejmpbldmpobfkfo. Find the "service worker" entry at "Inspect views" and click it. Do you see errors at this console tab?

is there an equivalent to this for safari? i've been having issues every tuesday for over a month now

This didn't work for me ;/ Did anyone find the solution?
My scripts stopped working altogether, even though they show as active on the pages they should be. I tried reinstalling Tampermonkey, but no luck fixing the issue

@axel-magard Please to to chrome://extensions, enable developer mode and press the update button at the upper left.

@FabriceNeyret This errors are not related to any Tampermonkey issue.

@EricE549X Please check #2153

[rcchan]

Same issue for me. Mine was related to #2011 and temporarily re-enabling via chrome://flags/#mutation-events makes the scripts work again.

If you're seeing "MutationEvent is not defined" as an error in the dev console (for the sites you're visiting, not the background or options pages for tampermonkey) this may be the same issue for you.
