非常棒的一个插件
Chris, your tools have filled in some nice gaps that help with productivity. Thanks for carrying forward what you started in FireFox to Chrome.
It's awesome. Today I found my first issue, and Chris showed me the solution so I'll share it here: This extension seems to over-ride the default "always ask" way of dealing with notification permissions, as I got a notification today from a domain which I never approved, and it appears this extension is what allowed that to occur. To fix this you can remove the over-ride settings by selecting ‘Disable’ -> ‘Reset Disable Features’ option in the extension.
Used to work great with the latest Chrome for many years and was my go-to tool for looking at element outlines, but now it is no longer functional. Selecting an outline option throws a JS error. Hoping that's resolved so can revert to 5 stars again, but I see that this is not being maintained.
Качественный продукт! Функционал, при перепроверке, не подводит.
The option to "View Image Information" does not work.
great tool for web developer
Been using this on firefox for a good few years, only went looking for it on Chrome this evening
dont work with local files :(
It's Okay !
