Could be better if it doesn't automatically closed when the page is reload just like the inspect elements it doesn't automatically close.

Please fix this.

Better than nothing but not really usefull. The network tab is useless. It is empty when the extension starts and the extension will disappear when you reload page. So only lengthy deferred loading will show up. I guess this is the same for js errors.
Source code has no color highlighting (listed as a feature ???) and you can't select parts of text.
Console has no code completion.
So what is left ? You can execute js on the fly and you can browse the content and cut/paste nodes.

I am using it for almost 2 years , it is best.

This extension is awesome. I would really appreciate the possibility of editing the html.

It about 2025 now I found the thing/s as same I do in FF pc version all the year. Tq for absolutely stunning tools to work around.

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

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.
