This could be a software design that only properly displays on their Browser. As you stated other browser show the same problem should that would indicate it's a programming issue.

Hello and thank you for feedback! Can it be fixed somehow? This's definitely not a GWD issue. As the specialist said, he tried to fix it out even with additing the CSS code but again, the result remains the same. GWD also includes prefixes for a creative as a default option so this banner initially should be cross-browser

Hi DeanMarshal, can you provide a link to a page demonstrating this problem? We would of course want to view it as anonymous members of the public, without access to editing/previewing tools.

See also the Inspector.

Hi! Thank you for feedback and I'm sorry for delay with answer

Here's the link on preview (AdBlock'd be turned off)

In addition to this, I'll attach a static file so that everything can be clear

Can't reproduce it in any way.

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0

I see a one-pixel difference (see attached).

Could you try:

New Profile Test

This takes about 3 minutes, plus the time to test your problem sites.

Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it.

Click the "Create a New Profile" button, then click Next. Assign a name like May2019, ignore the option to relocate the profile folder, and click the Finish button.

After creating the profile, scroll down to it and click the Launch profile in new browser button.

Firefox should open a new window that looks like a brand new, uncustomized installation. (Your existing Firefox window(s) should not be affected.) Please ignore any tabs enticing you to connect to a Sync account or to activate extensions found on your system so we can get a clean test.

Does the problem site work any better in the new profile?

When you are done with the experiment, you can close the extra window without affecting your regular Firefox profile.

You may have accidentally zoomed web page(s). Reset the page zoom on pages that cause problems.

• View -> Zoom -> Reset (Ctrl+0/Command+0 (zero))

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

Hello! Thank you again for feedback. This's neither zoom issue and nor a problem with the cache or cookies, because I created and placed this banner on the new domain.

An update. The same problem is at another Google specialist, but at this time in the Chrome browser (74.0.3729.169) on the Mac (os 10.14.5) So, it can be assumed that this problem is also a multi-platform.

Hello! Thank you again for feedback! So, everybody who will want to see this ad properly should make the same process?)

Did you verify what font Firefox is using because a font that is higher can cause this to happen?

You can right-click and select "Inspect Element" to open the builtin Inspector with this element selected.

• https://developer.mozilla.org/en-US/Tools/Page_Inspector

You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Font tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website.

Well, the position on yours is different from everyone else who commented, so this test is to see whether that could be due to some issue in your profile.
