Nghia Truong Trong (ID: 0000006dfad03af8) Voted 5 ★ - Updated 10/17/2023 This does exactly what I needed it to do, I force some mobile website on desktop

Pascal Collard (ID: 00000030323917c0) Voted 2 ★ - Updated 08/28/2023 Only feature I was looking for in this add-on was to overwrite the body response. However, and even though it's only supported in Firefox, that doesn't even work there with the current version of it (102.14). Submitted a support request in their add-on's github and got no reply after a full month of a wait. May work well for other features the add-on offers, but then there are plenty others which I'm sure would be easier to use as the UI of this add-on is not the most intuitive anyway.

Tyler Black (ID: 000000dbfa9b5ca3) Voted 4 ★ - Updated 05/30/2023 Good extension, unfortunately not as good as the firefox version due to Chrome's limitations. For example, you cannot edit the cache control header prior to entering chrome's processing pipeline to fix websites setting bad cache parameters that force full page reloads unnecessarily. But this works on firefox.

Ladia Zhang (ID: 0000007a98c40634) Voted 5 ★ - Updated 03/17/2023 用它重定向请求(比如重定向去镜像网站加速访问),拦截一些请求是好用的 就是改ua感觉有问题,我改了一个网站ua然后抓取时看着改了实际没改,那个网页会根据ua判定 原浏览器ua会404并重定向去别的网站,手机ua才能访问 用这个改就不生效 没办法我又下回来user-agent switcher来修改ua了 以及不知道为什么在这个扩展的编辑页面特别卡
