Is the scaling setup properly for Windows ? If not open the controls and get the screen scaled to what ever you have that opens up after boot.

Reboot after making changes.

If still problems with Firefox then please uninstall it then reinstall Firefox 61.0.2 with a Full Version Installer

Hi, not really understanding the above.

When I do a Refresh on Win10 Install my drivers then have to bring up scaling right away as every thing is pushed out/around on a 32" So fix the Scaling and I am done with it till next time I do a refresh.

So scaling is the 1st thing done, nothing else needed after that.

I gather that is not happening with yours ? What video card ?

Gtx1080, scale on win so good

Ok, got your card but do not understand the rest.

Are these the drivers you installed ? https://www.geforce.com/drivers/results/137270

Yes I installed that driver

Scaling issue should be posted to a Windows forum that is something O/S related the Browser uses what the O/S gives it.

So, OS is not reason of my problem.

Please take screenshot of the desktop, then the browser and the problems https://support.mozilla.org/en-US/kb/firefox-screenshots

Please further explain the problem to go along with the pictures.

Save pics as png or jpeg as they are compressed.

Take, first screen, before switch tab, second screen, after switch.

The 2nd picture shows the page has been Zoomed 150 %

Set Zoom to 100%

Do you have enabled "Resist Fingerprinting" if you check this pref on the about:config page?

• privacy.resistFingerprinting = false
• https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Blet, *first and csecond screen of tab*

Cor-el, I not understand.

Sorry, my English is not good.

Firefox has a feature to adjust some settings to make Firefox look like a generic browser. This feature is called "Resist Fingerprinting". When this is enabled then the user agent would have been changed as well, so it isn't likely that you use this.

You can check other prefs though that deal with zooming.

• browser.zoom.siteSpecific
• browser.zoom.updateBackgroundTabs

Firefox comes with a builtin page where you can inspect pref. This page is named about:config. You can open the about:config page via the location/address bar like you open an internet page. You can accept the warning and click "I accept the risk!" to continue. More:

Thank. Today i check other sites, so, zoom on other sites worked, but on 2 sites zoom works with errors. What is it? Please, write so that i can understand you.

What kind of errors are you talking about?

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

Can you attach a screenshot?
