Quite frequently the LT extension makes Thunderbird unresponsive. Sometimes an error message comes up, sometimes I need to kill the program. I run Thunderbird (128.5.0esr (64-bit)) and the LT extension (8.11.2) on Linux.
That’s the error message:
A script from the extension “AI Grammar Checker & Paraphraser – LanguageTool” is running on this page, and making Thunderbird unresponsive.
It may be busy, or it may have stopped responding permanently. You can stop the script now, or you can continue to see if it will complete.
Script: moz-extension://bd1b9fb8-ab5a-…5-ae60-94d973ce5dcb/content.js:61
Prevent the extension script from running on this page until it next reloads
