There are a lot of addons that imply a permanently open sidebar - Tree Style Tab (177k users), Simple Tab Groups (64k users), Sidebery (34k users), Tab Stash (21k users) and a bunch of others that are not related to tabs. In your addon, the "fit-to-window" image scaling mode still doesn't take into account the open sidebar. Your addon scales the image really "fit-to-window", but should scale them "fit-to-content-area-visible".
For all these hundreds of thousands of users, your "fit-to-window" mode is meaningless and useless.

I was ready to delete Firefox, and go back to Chrome because of its sub-standard zoom ability. Then I discovered Zoom Page WE, and I'm back to loving Firefox. They sorely need to incorporate the capabilities of this extension into Firefox!

Highly recommend! Very useful and flexible. You can customize size of page, font or both. Makes website easier to see and use.

Thanks

very excellent and intelligent autozoom addon.

amazing extension, a life saver.There are other extensions like it but this one is miles better in terms of convenience and customization. Every once in a while it stops working but the dev is always very responsive and quick to fix it

Hey, `Cmd +` and `Cmd -` to zoom does not work anymore since the latest version! 😢

Please fix, thank you !

EDIT:
Thank you for your reply, will try that. I was already running 19.5, i reverted to 19.2 and disabled updates, which fixed the problem.
