It breaks UPS printing. Try to print a label from UPS or Amazon and it will only show a blank page. As soon as I disable this broken addon printing wo9rks fine!

In the changes for this addon, it says Version 17.12, yet after install version remains at 17.11, with all documentation for 17.11. Not sure what rev I really do have.

Edit: The issue below is now fixed. However, it only gets 4 stars because of the frequency of problems that this extension suffers from. End Edit.

After the last Firefox update, this extension breaks the display of google image thumbnails in image searches. If the Zoom levels are over 108% (on my system = 1080p), all images thumbnails are displayed on the left hand side in a single column. It also breaks many other websites (abcnews.go.com, for example). This is a great extension ... when it works, but it far too often is broken or breaks sites, and it takes a LONG time for fixes. Cannot recommend.

After the last Firefox update, this add-on gives me problem on Overleaf. Hope you'll fix it because is a really useful add-on.

New version 17.11 late December update broke websites, especially amazon. Had to revert back to older version then all was good. Both hoverzoom and zoom pages update did the same thing too.
*Had to go back to 11.09 for firefox homescreen pagezoom to work

17.10 works well. 17.11 breaks images on many wordpress based sites. too many to list here.

too many permissions.

It does not work on youtube so be aware of this.

Works on most other sites.

супер

不具合。bugs

１５０％指定の状態でAmazonの商品をかごから削除する操作などをすると、操作するたびに文字サイズが大きくなる。

設定画面が複雑すぎて何も設定できなかった。
UIが英語。CUI。理解できない。so bad.
シンプルなズームのアドオンがほかにあるので、それを使います。

このアドオンは「おすすめ」に表示されるけど、これは使えない。why recommend from Firefox?

It did nothing when I clicked on anything.

This addon was indispensible before FF introduced zoom, and worked very well. Now it is useful to enlarge the text size only, while keeping the general zoom set in FF which was 67% - a fix for the latest fashion to use mouse print separated by huge empty spaces in web pages!
The dropdown text/full toggle didnt work I had to set it in options. After that, Ctrl_+/- enlarged/reduced the text only while the frame stayed at 67%. Exactly what I needed.
Had to disable it to view other pages on the site, because I don't have time to figure out all the repercussions of changing config to enable per tab (I recall it stopped the FF default zoom happening on page load, had to click the size button on every tab); also Zoompage adds masses of resizing code in each tab so affects performance.
