This is because you have an older version of MacOS: [[Firefox Mac OS X 10.9, 10.10 and 10.11 users move to Extended Support Release]]. The last version for 10.10 is what you have. Can you use Safari for FreshBooks?

I need Firefox 98 in order to use FreshBooks but for some reason the browser is not updating. So how can I fix the auto update? </blockquote> If you had macOS 10.'''12''' (ten.twelve) or later then you should get internal Firefox updates. However Fx 78.15.0esr was the last to still support the old macOS 10.'''10''' (ten.ten) you have. https://www.mozilla.org/firefox/78.0/system-requirements/ https://www.mozilla.org/firefox/79.0/system-requirements/ https://www.mozilla.org/firefox/99.0/system-requirements/ ''<p>FredMcD [[#answer-1498473|said]]</p>'' <blockquote>If you have trouble with the upgrade, use this link; '''http://www&#46;mozilla&#46;org/en-US/firefox/all/''' </blockquote> Will not work since the OP has macOS 10. '''10''' and if the OP were to try to install Fx 99.0.1 they would then had to reinstall 78.15.0esr.
