The extension shortucts interfere with Windows special character alt codes, such as when I want to type Alt+0149 for a bullet, the window resizes to one of the user-defined sizes as soon as I press 1 after 0 when holding the Alt key down.

I cannot change this in Firefox versions earlier than Firefox 66, as these older versions do not have an extensions shortcut manager.

I recommend making Shift+Alt+[number] the default instead of Alt+[number] in future versions of WindowSizer.

To each it's own..... I quite like it !, BUT, in my opinion, be a lot better with an option button to allow positioning the resized version ( Ie; Leave unchanged, ctre in window etc.....)
Best of luck ;0)

great Job! I could have given 5 stars but, its missing one feature. If you can add the feature where people can set the left and top position of any window in addition to setting up the size, then, it will be a best addon in this world!

すばらしい！　欲しかったのコレです。
良設計だと思います：シンプルインターフェイスでわかりやすい
星マイナス１の理由：使って未だ１０分しか経ってないので… すみません…

great! This is what I was looking for.
I suppose this extention is good design: simple interface and easy to understand.
Reason about score of minus 1point star: I have used it only 10 minutes yet... sorry...

Save browser Window Size and restore.
This function is the best ,but For me Something missing
That's right, save and restore the window position!

Function Insert about save browser position ,restore one.
That function Insert this add-on
I create this add-on Name:WinSizeNPosition

Please use my add-on, too

This extension works well, easy to set up.
It allows to set desired window sizes.

to developer:
1. Thank you.
2. Current window size is show only in preferences, it would be way better if it's shown in the drop-down.
3. Naming is great, it would be better if blank name was allowed.

Very nice & useful add-on! Thank you
