Finally,this addons solve the problem.

Allow a fixed zoom level for all websites at all times.

What's great about this is that it's a "set and forget." It always works. If a rare page needs to be zoomed, ctrl-+ and ctrl-- work as always. Thank you to the developer!

does not remember settings

操作简单, 界面美观. 有一个问题: 在 Firefox67 Dark 模式下 browser_action 图标无法显示

I've only been using this for 10 minutes, but I've had a play around and it's exactly what I was looking for!

+ Simple to get started
+ No unnecessary permissions
+ Powerful advanced features (auto-saving when zoom manually changed, regex matching of URLs for rules)

My only suggestion is to list the advanced features in the description :)

Thanks for the great extension, it's a pleasure to use!

it seems alright!

Most welcome replacement for NoSquint which I felt was lacking behind. The performance issues NoSquint sometimes caused doesn't seem to happen here plus rules are a breeze to make. Not to forget the neat icon and interface. Keep up the good work :)

非常好用

Amazing addon. A solid replacement to other older and less reliable addons. This one combines functionality and beautiful design. Firefox just got a little better.

Simple yet powerful

Exactly what I was looking for. Helps me a lot on my 38" wide screen. Thanks a lot!
