- (2023-05-14) John and Jane Doe: Works pretty well (despite runtime.lastError; try putting your code in JQuery document ready). I wish it could be set to work on specific pages rather than whole domains.

- (2022-07-05) Lavanya Mishra: 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!

- (2021-11-28) Crowtower: 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!

- (2021-09-14) Kamil R: 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

- (2021-02-15) This is what I've been looking for. I have few questions though: a) When does the code run? Before anything else? DOMContentLoader? onload? b) If I don't use jQuery is it going to be used on the page anyway?
