I love the promise, but this currently gives the following error: Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist. Looking for an alternative.
When this extension is enabled the following error appear in the DevTools console: Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist. Dev, please check: https://stackoverflow.com/a/60323713/4938623 https://stackoverflow.com/a/54686484/4938623
Not running after page refresh, had to manually trigger run from chrome extension
This is the best extension available for this task, incredible work!!!
This extension is a bomb!!! Thanks for making it! :D I tried achieving the same thing using local overrides but that wasn't working as intended due to redirects on the website. This extension will save so much of my time. Again, thanks a bunch :D!
I was going to write my own extension just to rewrite the browser url if certain conditions were met. This little extension saved me the hassle! It works perfectly!. My only feedback would be that the extension icon is a bit ugly haha. Thanks for making this!
Very helpful!
working as intended. But there should be some feature to make an cloud backup. Would be also good if you add some prefiled event listeners, like run code when page loads, when dom ready etc, because sometimes you have to wait with code until content appears
nice
pinned icon could be better (transparent) and it gives me this error on console when developing on localhost: `Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.`
