I have an older iMac power PC computer which current versions of Firefox will not work on. How can I stop getting pop up messages telling me to update?

hello hpalmer, you can disable the firefox update notification in preferences > advanced > update. if you want to use an up-to-date browser based on firefox you might try switching to "tenfourfox" - the downside is, it doesn't support plugins: Firefox no longer works with Mac OS X 10.4 or PowerPC processors

in addition there have been notifications for users with vulnerable versions of the flash plugin during the last few days - on mac osx based on the powerpc architecture it is also not possible to update flash any longer. if you want to disable these warnings, enter "about:config" into the location-bar of the browser, confirm the info dialog, then search for the preference named "plugins.hide_infobar_for_outdated_plugin" & double-click it in order to toggle it to "true".

you might also want to use an addon like flashblock to only enable the flash plugin when you need it (like when you're watching a video on youtube) in order to mitigate the risk while surfing the web.

Thank you for your helpful answer. If I am at increased security risk with an older version of Firefox would I be better to switch to another browser like Safari or Chrome where I could get a more up to date version on my iMac Power PC?

This is another pop-up message I keep getting on my iMac G5 Power PC. "You are using an old version of Firefox which Gmail no longer supports. Some features may not work correctly." Is there a way to disable this message? Thanks!

That message comes from the Gmail (Google) site and is caused by code that checks the user agent that identifies you as Firefox 3.6.12.

You should consider to update to Firefox 3.6.28, the last Firefox 3.6.x version.

You can find the latest Firefox 3.6.x release in all languages and for all Operating Systems here:

You could spoof the user agent to stop that mssage, but that can cause problems with websites that send code that is incompatible with Firefox 3.6.x

Yes, you are better off switching to a different browser than sticking with an unmaintained version Firefox.

Unfortunately, there is not really a more modern and updated browser for this old a computer. Also, the Operating system itself does not receive security updates, so by just using this computer online is horribly insecure.
