Good day folks... :-)

The Zoom facility in Firefox + or - jumps in rather odd increments, and
I'm wondering why and is it configurable somewhere?

I'm particularly interested in the minus values.
Example:
The default here is 100% click (minus) - and it decreases to 90%, 80%,
67%, 50% and 30%

Earlier today I was doing some work with Fx and could have done with a
minus value somewhere in between 50 and 67% (55 or maybe 60%).

Can the values be reset/configured somewhere or are they hard coded?

Thanks
Dave S

Search about:config for zoom

See <https://kb.mozillazine.org/Toolkit.zoomManager.zoomValues>

I have not tested adjusting the preference - do so at your risk not mine.

But also see <https://support.mozilla.org/en-US/questions/1245141>;
which implies that in some cases you may also need to restart Firefox.

Yes, that works okay.

Thanks

I changed my zoom. I wanted a bit more granularity.

Try the add-on NoSquint Plus. Very adjustable and can remember
different levels of zoom for each web site. Does not disable the Ctl
+/- feature built in to FF.

While that setting specifies the increments when using Ctrl with + or -
keys, using Ctrl+mousewheel changes zoom in 10% increments. Maybe the
fixed 10% increments by using the mousewheel would provide the smoother
zoom change the OP wants.

With Ctrl+mousewheel, the minimum and maximum zoom at 30% and 500% with
10% granularity.

After the advice yesterday, I'm using both methods.

I've made a couple of adjustments in Fx Preferences and am using the Ctrl
+ Mouse scroll for a particularly troublesome magazine reader.

Appreciated the advice.

If you use Windows, at least in Windows 10 (haven't migrated to Win 11
yet), go to settings and search for Magnifier. If you turn Magnifier
on, you can use the mouse wheel to zoom in/out if you hold down the Ctl
and Alt keys at the same time. Zoom adjustments can be set to between
5% and 400% on my PC.
