    Vary useful but downside is that we cann't mock more then one api
  • by george_work, a month ago
    far more easy to use than alternatives, yet provides all the features I need (intercepting requests and replacing with mock responses)

    pity that they've decided to focus on Chrome, feels like plain laziness tbh, other extensions get by fine.

    It has saved a lot of development time for me. Works beautifully.

    According to the Website, there is already a version 8.2.0. However, this version is not being release for Firefox for whatever reason.

    Hello, indeed, we haven't released a new version on Firefox in quite some time due to platform limitations. We had to adapt to major changes to keep you with the Chrome platform and we left Firefox behind hoping that Firefox and Google would align on a standard for extensions, but they never did. It's quite costly for us to maintain this add-on as of today and as most our paid customers use Chrome and feedback here is very negative compared to Chrome's we're considering dropping Firefox entirely.

    Thanks for your understanding,

    Seem to have completely stopped working some time ago (and looking at the last update, not surprising – looks like Firefox is at least 2 major releases behind). When enabled, requests are significantly delayed and always replaced with no content instead of what is in the response field. It might be a CORS issue, but I am not sure. Anyway, any intercepted request will end with unexpected end of data at line 1 column 1.

    UPD: Obviously the feedback is negative, the extension does not work, simple as that. Why would an Open Source browser have to comply with a Google Spyware Machine? Unfortunate, but it's your call to support spyware instead of browser.

    Was looking for a way to return a specific statuscode and error message on a request to debug an issue and this extension had me covered in a couple of minutes. Lifesaver for sure.

    Perfect extension
  • by Calvin, a year ago
    Nice looking UI, immediately got it working in less than 5 minutes for a simple stub.
  • by Stephanie Hobson, 2 years ago
    Took me a second to figure out how to use it and then it worked like a charm 💯
  • by Daniil, 2 years ago
    This extension is very helpful for web development. You can easily mock response from API and play with it.
  • by nik, 2 years ago
    Simple to use, it took me a few minutes to mock my first response.
    Thank you tweak team!

    It took me about 2 mins to set it up and mock the server response for my development - Thx!

    Unreliable. Even with a regex "match all" url matcher, only a small subset of requests are processed.
  • by Firefox user 15400081, 2 years ago
    Did exactly what I wanted which was to cause the UI display to behave according to the response. Worked well in Firefox. In Chrome it says it was installed but I couldn't find icon on the toolbar.
    Found the popup a little confusing because when I moved away it would disappear and I had to press the icon to show it again when I needed it.

    Thanks for your review, indeed Firefox makes a better job at displaying the extension in the toolbar. Please note that extensions in chrome have a new UI https://imgur.com/IOT6RJg. You need to click the icon in this image - https://imgur.com/IOT6RJg - in order to see newly installed extensions.

    We would love to chat more about your experience so far, if you're interested, send us an email at help@tweak-extension.com.

    Doesn't work at all. Doesn't intercept API calls.

    Hi Dalkavar,

    Sad to hear the extension is not working at all for you. If you would email us at help@tweak-extension.com we can follow up with you and perhaps schedule a quick shadowing session for you to expose your issue to us.

    Thank you,
    tweak team

    Did not work for me. Tried 4.6.0 and 4.5.0.
    In one case, the extension counts the number of URL matches it finds, but does neither the delay nor the response replacements.
    In another case, it does not even count the match.
    Followed the instructions in https://tweak-extension.com/docs/intro carefully.
    Tested in Firefox 95.0.1./MacOS

    Hi Semper,

    Thanks for your review. As you can read in our faqs, the extension might not work for certain websites that deviate too much from standards (e.g., applications that mutate globals such as window.fetch). You can read more about this on our FAQs page https://tweak-extension.com/faqs#will-this-work-in-every-web-application. Thanks for trying tweak
