A+++ most relevant,easy to set up,works stably

*EDIT*
The extension always had support for such urls! All I had to do was enable regular expressions and voilla! Glad I rated 5 stars even initially!

Super useful and straight to point extension for firefox! The only feature I would ask as a developer is to let me add rules for localhost ports so my actual testing sites dont show the custom zoom levels. Thanks!

Works perfectly, looks CLEAN, and has really cool power user features

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!
