URL Throttler

Lol you just add a website and then it will magically do something apparently. No options at all no thanks.

Works just like a charm ;)

Awesome extension. It helped me to debug an issue. Very easy to use!

Good and simple, not bloated (unlike "Requestly"). Works if you need a delay working on your daily browsing. For development-time only, a similar extension "HTTP Request Blocker and Delayer" works only when DevTools panel is open; it also provides a bit more flexibility for each URL/rule (e.g. different delays). Blocking multiple/parallel requests seems to be a Chrome API limitation, see the GitHub page for the "HTTP Request Blocker and Delayer" extension. Use Firefox instead.

Unfortunately, the extension does not handle parallel requests. That is, if you set a mask for one domain, then get ready for all the styles, images, scripts, etc. will be processed one by one!

Works like a charm! But can I set different delay for different rules?

super useful for selective throttling, thanks

Simple and it works as intended

Extremely useful extension

Sad that it has no option to set delays per request and also turn specific requests on and off, However it does its job.
