It’s not though and I only experience it on Mumsnet. Really don’t think they’d send out an email to everybody if it’s an individual device issue. This was sent unprompted in May and they’ve done nothing.
“You may have experienced freezing or crashing during longer browsing sessions on Mumsnet, particularly on Safari, and I wanted to explain a bit more about what’s going on.
Over longer sessions, browser memory usage can gradually build up because of advertising and other third-party technologies running on the site. Eventually this can cause pages or tabs to freeze, crash, or refresh unexpectedly.
Safari has lower memory limits than some other browsers, which means people using Safari during long sessions on Mumsnet are particularly affected. This is not unique to Mumsnet and can happen on other heavily used ad-supported sites too.
I want to reassure you that I and the team are actively working on improvements. We’re currently testing changes including different ad partners, lighter ad formats, and reduced ad refresh rates to try to reduce the problem. However, this is a technically complex issue involving browser memory limits, long browsing sessions, and third-party advertising technology, so it is not something we can fix overnight.
In the meantime, a few things may help improve your experience:
where possible, using Chrome instead of Safari, as it tends to be more stable
clearing your browser cache regularly
making sure your browser is fully up to date
closing older or unused tabs during very long browsing sessions
bookmarking longer threads so that if a page refreshes unexpectedly, it’s easier to return to where you were
I know this is frustrating, especially for those of you who spend a lot of time reading, posting, and supporting others on the site, and I really appreciate your patience while I continue working on improvements.
Thanks,
