Works great if you make sure to only use two settings.
1. Use the built-in browser zoom
2. Zoom at web page level

Do not use the zoom at domain level because your other sites will not reset default zoom back to 100 on all other sites. Using these two options you can set Zoom level for specific sites and not affect others. The other Zoom option types mess up the X and Y coordinates so don't use the defaults.

This addon is very good. But there's one little issue. When the font zoom is set, then if you increase font size in a website which contains hidden / collapsed text, it does not affect the font size of this text after unfolding it. Like in live-journal posts and comments.

UPD: I disabled all extension esxcept your ZOOM. The effect is the same: the unfolded text in lj has a smaller size than the text before the unfold button. I have to manually trigger Zoom button (plus then minus) to bring font size to norm.

Excellent Add-on！ Thank you so much :)

Sehr gute Erweiterung , weil ich jetzt Text und Fotos in selbstbestimmten Abstufungen hinein und herraus ZOOOOOOmen kann.
Das gibt meinen Presentationen von Webseiten noch mehr Flexibilität.
Natürlich ist etwas EinarbeitungsZeit notwendig, aber die Mühe lohnt sich.
Auch vielen Dank an den Stefan , das er so ein schönes Tool programiert hat.

5stars. Need the 3 Engine options to show in the popup for best up.
Maybe 2 bars, one for text other for page zoom
200iq tip: Can work together with built-in browser zoom.
