Love this add-on and have used it since its beginning without issue. However, as of today the add-on will no longer save my defined position when I click save in the settings, and it places my FF window off to the right when I click the position button. Any suggestions?

Thank you for this extension. I love it and use it so many times per day. It saves me from my OCD about browser-sizing :)

I think it would be great if different saved window sizes/positions could be accessed quickly from the context menu (by right-clicking on the icon). I like to have multiple browsers open in different positions on the screen. Single-left-click should still put the window in position 1. Also, maybe a double-left-click could put the window in position 2?

Also, I badly wish Thunderbird had an add-on that could do this. I wonder how difficult it would be to port this add-on.

Great! but can you decrase the limit from 640/480 to 300x300, i need resize a popup to 300x300 , but when i set right >1280 (on a 1920 screen) i become invalid (Thx for the fast update, greetings from Germany)

This extension does exactly what I was looking for. Many thanks.
Can you make it accept negative margin sizes?

What a handy and simple extension. I always hated it, when my Firefox window was resized or moved around (often by my best friend ^^). Now it's just a single click to bring it back to my preferred position again (pixel accurately centered and aligned with my Rainlendar). Thank you! :-)

Simple and brilliant little add-on! Perfect for resetting the browser window to the exact size and position you're used to.

A little problem is that it doesn't work in github
But it still works perfect with up 0 left 0 down 40 right 60 on blog or something website.
Super thank you!!

What a nifty little add-on! Simple, precise and effective (in FF 56).
Thanks Soustruh.

Simple, beautiful and reliable.

It does not leave the amount of pixels on the right I specify but I'm able to add 640 pixels to get the desired size.

Also when I click the resizer icon the browser window does stretch to full height but the bottom part goes behind the taskbar. Tried minimizing and restoring window but still behind taskbar.

Perhaps option to control how much space is left above, below and to the sides of the window can be used to fix/adjust this issue.

Thanks and really appreciated :)

Very simple and reliable add-on.

I'd like to request more control over the positioning of the window. Perhaps options to control how much space is left above, below and to the sides of the window? I'd like to be able to reset Firefox's position to a specific place on the screen, rather than always at the top-left.

Thanks!

Just working.Excellente.
