Recently switched from Chrome but it took a few days to find this add-on (Mozilla have extremely helpless search/help systems!). There are plenty "window resizers to standard resolutions" but no like this one - with fixed window position on desktop. So I just copied my sizes/positions from Chrome extension - works like a charm, thank you!

Does one thing, and does it very well Rated 5 out of 5 stars

I've had the venerable Web Developer extension installed ever since it was released, but as Firefox’s built-in developer tools have become more powerful I’ve found myself using progressively fewer of its features, and so I plan to replace it with more focussed add-ons and reclaim the 26 pixels taken up by its toolbar.

The built-in developer tools now include a ‘responsive design mode’ (Ctrl+Shift+M) that creates a smaller viewport within the viewport, but its refresh rate when resizing is noticeably slower than when resizing the browser window itself. In contrast the Resize button on the Web Developer toolbar resizes the window, but is inaccessible when the window is less than 620 pixels wide.

Browsizer can be added as a button on the main Firefox toolbar, displaying either an icon or the current window dimensions. Clicking on the button lets you choose a ‘geometry’ to resize the window. Geometries can include not just the window size but also its location on screen, which is useful if you’re somewhat obsessive and like to have your browser precisely positioned.

Browsizer does not attempt to be an all-encompassing tool for developers. It does one thing, and it does it very well.

Yep, found it: this is the best alternative for the Firesizer add-on since the status bar was dropped with FF 29!

It's easy to put all your favorite browser window sizes in Browsizer: manually or automatically by saving current size, inlcuding the x and y position on the screen. One simple drop down menu, which is accessed in the top tool bar, gives you all the necessary settings.

What I especially like is:
- that you can choose between an icon in your toolbar or the current window size in numbers (which also brings up the drop down menu when clicked)
- that set sizes can have an extra label/description

The only flaw maybe: it seems you can't re-order the list of sizes by dragging them. Browsizer does the ordering.

Great add-on!

Very Useful Rated 5 out of 5 stars

Love this add-on. It does exactly what I need, to fit different monitors and to simulate different window sizes for Web development. It would make more sense to left-click rather than to right-click.Great add-on!!

Better than old version Rated 4 out of 5 stars

Please add an option to leave the button as a button instead of becoming text (ie: appearing as 1104x885 instead of just being a button).

Very happy that the 'button' can be moved out of the Add-on bar, unlike Firesizer. Thank you for continued development!

works as it should Rated 5 out of 5 stars

Thank you. One minor quibble: settings can only be added (ie. created from scratch) or deleted, not edited--that would be handy.
