A very useful and eye-catching extension that does more than just go to top or go to bottom. When one hovers over the on-page icon, it shows page-up and page-down. Well done.

Saves time.

it's nice and very comfotable

Been using this extension for a number of years now, mainly on Google Chrome but recently gone over to Firefox Quantum (58). For some reason this extension does not work on the BBC WEATHER page. It appears at the bottom right (My Setup) but does not send the page back to the top when clicked. All other sites work fine. Not a big problem as most of the info is at the top of the page.

Very good. Thank you!

Please add support mobile firefox!!

Simple, elegant, convenient. 10/10.

I just have one recommendation: option to customize the button using CSS. Then it would really have been awesome!

Great add-on!

However, I've noticed something:
I was updating my blog on WordPress. My up&down arrows are vertically set and they were very close by the WP Update button. Despite I clicked the WP Update button outside of the up&down arrows, the WP Update button didn't work whatever I tried. (Also, on that particular WP edit page there was no place to move the frame away from the arrows.)

I think there are more blind spots around the arrows than I thought.

nice and useful add-on

Arrows jumps to left a bit from side in vertical dual arrow mode on mobile (when tap on it) and on PC too (when mouse hover).

For some reason recently, I found STT stopped working on my updated Firefox v.55.0.3 (32-bit) and I desperately searched for a replacement add-on; all came up short.

Anyway, it seems the dev was working on this new Mozilla-mandated compatible one, and I was glad to have it back.

I don't mind donating for good apps (exts) I use frequently. I may install many, try *some* out, find them wanting, and subsequently remove them. This is not one of those; it's a definite keeper!
Besides being able to scroll all the way to the top and bottom, you all also have incremental scrolling up and down. There are also lots of customization options too.

Good on you dev for making a new version to work with Mozilla's new WebExtensions.

Not working on firefox 52.0.2 linux, please fix it if possible, or how to downgrade this addon

This add-on have preformed consistently through the years! Now migrating to the new format is AWESOME!! Thanks for your efforts they do not go unnoticed, they will be rewarded!
