For you and GeorgeCheers. I've used Firefox and Chrome without issue on a Pixel phone, Galaxy tablet and Windows PC and haven't experienced this.
From your further posts it sounds like it's related to ads - have you identified a specific ad, or type of ad, that causes this specific issue?
Feedback for you from my testing today.
I have downloaded Google Chrome and am testing the BF website.
My complaint relates to the user experience of the BF website using Safari as the iPad browser.
The site is unstable on Safari.
All the prior images sent have been from Safari.
Note on the attached image below, the link to open the BF app that appears at the top.
That does NOT appear on the BF site in Chrome.
That link is repeatedly removed by me, but reappears anytime the page is re-opened or refreshed.
It may also appear as a result of an ad script, but as I’m reading the page I am not looking at the top for the appearance of the app link. So that’s only supposition on my part.
Chrome is significantly more stable based on testing today, so far there has been no change in page sizing or font sizing.
I am yet to experience the second fault (page shrink when running a specific ad type).
As mentioned to George yesterday, I will shoot you a screenshot when it happens next, simply so that you understand how the BF website responds.
Another thing that I have noticed, when commencing a new sentence on a new line in a post, Safari wants to indent (by 1 character). I don’t think that exists in Chrome.
TL;DR
Chrome is more stable than Safari and a better user experience.
I will continue to test Chrome.
I will forward a screenshot of the second Safari sizing issue when it re-occurs.
