I'm on an older Macbook Pro with OS 10.12.6 My browser says it's up to date.

It seems that ever since I did a sync-up with another Macbook, glitches have appeared on this machine. One thing happening now is that some websites take forever to load in, and others won't load at all. With other sites there's no problem. I have a fiber optic connection. The speed test indicates that all is good. I did reboot recently.

I'm wondering if some sites are using advanced scripts that my older machine doesn't like, or perhaps recent updates from Firefox just don't work as well on this machine. Any suggestions??

Hi, apologies this is happening, this sounds frustrating. Would you mind submitting a profile of the issue occurring? You can find documentation here: https://firefox-source-docs.mozilla.org/performance/reporting_a_performance_problem.html
