Very useful. But I would like an auto-run option when the browser closed

wonderful - used it all the time

Excellent. Works as expected. Options allow you to customize which data types to clear.

Unexpectedly deleted ALL data for ALL sites including history! Very frustrated! I thought this would be on a per-site basis, and now don't have site autocomplete for a while.

Easy to use, thanks a lot

I am personally missing ability for making exceptions for some sites.

so far this is GREAT. select the data you want to automatically clear in options, two quick clicks without menu diving.

There isn't any weird "access all data on all websites" permissions either. I never understood that, and is a deal breaker for me.

The UI and overall experience is clean and simple. Nice work

very good!

How I rated the add-on:
Did the add-on work as you expected it to? Yes, the add-on is worth 5 stars.

However, anytime I use this add-on, Firefox starts to consume super-high RAM and becomes unresponsive for 5-10 minutes. If I forcefully close Firefox, I receive a browser crashed notification within the same amount of time. -2 stars (can get pretty inconvenient)

Just because I have this problem doesn't necessarily mean you will.

What features did I like or dislike? I like all features, and there is none I dislike.

Is it useful? Very useful add-on
Is it easy to use? It is easy to use.
Will I continue to use this add-on? For now.

Other notes:
Creating a new account elsewhere to make the creator aware of bugs is totally unnecessary. -2 stars

Creator is attentive and still reads reviews. +2 stars

Creator will try to fix issue if you're willing to make a GitHub account. +1 star (I'm not willing to)
