I got curious and started looking into this. Looks like you can enable background blur in google meet if you're using the latest version of firefox, I just did myself to confirm.
All I need to do is by spoofing the user agent in about:config
, by setting general.useragent.override
to Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36
.
If I remove the user agent spoofing, google meet refuses to show the background effect options.
So my conclusion is google deliberately gate this feature behind user agent sniffing. Firefox is perfectly capable of supporting this feature.
Some discussion about the issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1703668
The only time I see websites break on Firefox is due to Firefox blocking their tracking script and somehow the website doesn't work because of it. In those case, it's not the browser's fault that the website doesn't work without the tracking scripts.
Other people mentioned Google Meet doesn't support background blur in Firefox. Firefox is actually capable to do that in the past few months, but you'll need to spoof your user agent to chrome, so it's not Firefox fault.
