Very nice add-on. Only one issue, that you can't edit html in realtime throught it

I wish i could edit the html tbh but other than that it's awesome

Simple and works.

Doesnt really help when it gets closed on redirect/reload. The console is empty after the extension is opend again..

There are such three bugs that greatly affect the experience:
①The set theme, transparency, and duty cycle cannot be inherited to other webpages and are only effective under the current domain name.
②The shortcut buttons do not appear every time a new webpage is opened. Every time a new webpage is opened, it is necessary to find this plugin from the plugin interface again and click on it, which is very troublesome.
③It cannot adapt to the width of the screen, there is content on the right side that is not displayed, and it cannot be scrolled to view.

Addon is closed when refreshing the page to measure network data in network tab

Very invaluable on Mobile Firefox. My case, to help creating filter for uBlock Origin.

I like the extension, very complete. But I would like You to add an extra task. Could it be possible to edit the local storage? Anyway Many thanks.
