I'd like to second the mention of weird zoom levels, and the most recent update also seems to be overwriting fonts on sites, making all content just look entirely messed up. Is it possible to roll back to the previous version? I depend heavily on this plugin for work.

Its not saving any of the Site Settings after the update.!!
Using Ctr+Mouse wheel zooms in & out, by like 0.03%

Go here for this other add-on that let's you finely control text and image zoom on a page-by-page basis, just like no Squint. https://addons.mozilla.org/en-US/firefox/addon/zoom-page-we/?src=search

NoSquint Plus was updated today to version 61.2 and 61.3 in my FF ESR 52.4.0 (32bit).
Since that, even after a FF restart, NoSquint Plus no longer works at all .

I can understand the "rewrite" for WebExtension is a major change, but really can't understand it's released in it's alpha-stage as an update

The "new" version simply doesn't work. It keeps forgetting and so it's useless.

It's free, I guess it's selfish to complain. However : Nosquint Plus does not remember its previous version saved sttings, nor does it remember its new version settings. Each and every page of each website you visit you have to set your settings for each and every page, you save the settings, and it forgets em. This glitch means Nosquint Plus is useless. I loved it ..... WHEN IT WORKED !!!

Immediately upon the latest version being applied, NoSquint disappeared from the menu bar and I now am relegated to going into "View" and have to use "Zoom" to adjust the screen and text size. I've closed out of the browser a few times (it worked for someone else to get it back) to no avail. My eyesight isn't what it used to be and I really depend on NoSquint to easily adjust the screen and text size. PLEASE FIX ASAP! It's great when it's working. Why does this keep happening every time there's an update?

So v61 started using webextensions but it is still allowed to update versions like FF48.0.2 which I still use (Mac Snow Leopard) and in the process break. Fine, I'll stick with 56.1 and suppress future updates.

I'm done with this extension. Every update breaks something and wastes my time going back and fixing everything. Avoid this extension and author.

Please stop releasing updates that are not working and crashing browser.

Never saw a addon has such frequent updating with nothing changed and annoying popups. My suggestion would be sticking with the earlier version.

The WebExtension only seems to zoom in in text mode, and doesn't zoom out. This is on Firefox 52.4.0 ESR, but this also seems to be a problem on 56.0.1 as well.

For now, I recommend people who need NoSquint to install the older version 56.1 and disable updates until this is fixed. Though do note it will break in Firefox 57.

Was it the NoSquint Plus update to 61.2 or the Firefox update to 52.0.2 update that killed it?

Stopped working. Again.

This stopped working today. It's constantly losing my settings as soon as I close save, or it just won't let me change them in the first place. After that it won't actually apply the setting to any sites. It's completely unusable. Is there any way I can rollback NoSquint to an earlier one that actually worked?

All was great then BOOM. Why cant people leave stuff alone ? Fix the broken stuff. Dont break the stuff that works.

Months, upon months of using this amazing add-on with my 4K TV, without a single hitch.

Then along comes this latest update, and it's like trying to use toilet paper as a beer mug: my web pages are all over the bloody place. I'm living in Wonderland over here, big-small-big-small ... make up your mind !
