Zoom For All Webpages At 175%?

Hello: I recently Reset my pc but now I set the websites for 175% but when i refresh the page it lowers to 150. I don't use Microsoft edge or Bing. I use Opera browser for years with no problem. I set the zoom in opera but it does not work from there either, Anyone know the path in registry for making the Zoom permanent at 175% In windows 10? Thanks

 

I don't use Opera. In FF, I press ctrl + several times until I get a website to the magnification I want. I can close FF, being sure to save cookies for the desired website. When I reopen FF and return to the site, the magnification I chose remains until I change it again.

 

Yes, I see what you mean, I dont use ff anymore, but it worked the same way with Opera before I Reset Pc. If I remember right, there is a setting in the registry that can control zoom on the webpages, but I forgot the Path to it!!!
