Abandonware

Doesn't work

Absolute trash addon, could not do the one thing I asked it to do which was TO CHANGE MY USER AGENT FOR A SINGLE WEBPAGE

Works like a charm. My very high end PC (to watch videos on Youtube anyway) was suffering on YouTube and my suffering only gotten worse over time because Google was trying Firefox users to switch to their browser. Noticeable difference right after installing the extension. Recommended to all.

Doesn't work anymore, no updates in sight to fix this.

Amazing, fixed a myriad of youtube playback issues using the developers guide.

All English. It can not use. Setting page = Very long text. No visual design.

色がよくない。

I recently started testing this extension. The last version "improved" the extension so much that it stopped working. It doesn't matter what user-agent it shows - browser tests always return the original one.

Need support for Android
