Very useful addon. The amount of times this addon has saved me from losing paragraphs of text is well over 100 at this point, and it is rare to run into a case where the text is not recorded (weird JS forms, WebAssembly, etc.)

CompConf·9 Feb 2026

This addon is so invaluable and the benefits are innumerable. It has saved countless devices from being lodged into the wall, it has saved the wall countless times from having holes punched through it, it has saved the bones in my hands from being broken, improved relations with my neighbors as they no longer hear me screaming at my screen all day, has lowered my stress and blood pressure and overall improved my health and mood on a regular basis. 😁

Very useful, saved me so many times, sometimes from my own inattention, often from badly behaved websites which flushed my text field. This extension saved me from having to re-type my text (as well as not being certain that I remember everything I meant to type, when having to restart from scratch). One issue with the most recent version 5.0.6, but not sure if that's a Firefox or extension issue, is that the extension doesn't update anymore. I check for updates, the new extension version is found, I install it, then if I re-check for updates it is found again. It seems like the update doesn't take. Restarting the browser and deleting cache didn't help. This happened on two very different Windows 11 machines (1/ personal gaming PC and 1 work laptop), both on FF 142.0.1. I fixed by by uninstalling and reinstalling the extension.
