Mozilla Firefox will require user intervention to connect to websites using the TLS 1.0 or 1.1 protocol from March 2020 – and plans to eventually block those weak HTTPS connections entirely. We have been hearing about issues with TLS 1.0 and 1.1 for some time. OldVersion.com provides free. software downloads for old versions of programs, drivers and games. So why not downgrade to the version you love? Because newer is not always bett. LastPass for Firefox (i386 and x64) LastPass browser extension for Mozilla Firefox. This will also work on other Mozilla based browsers such as SeaMonkey, Mozilla, etc. If you experience issues, try starting Firefox in safe mode.

On June 30th, macOS 10.9, 10.10 and 10.11 users will automatically be moved to the Firefox Extended Support Release (ESR).

While Apple doesn’t have an official policy governing security updates for older macOS releases, their ongoing practice has been to support the most recent three releases (i.e. version N, N-1, and N-2). The last security update applicable to macOS 10.11 was made available nearly 2 years ago in July 2018 (https://support.apple.com/en-us/HT201222). Unsupported operating systems receive no security updates, have known exploits, and can be dangerous to use, which makes it difficult and less than optimal to maintain Firefox for those versions.

Users do not need to take additional action to receive those updates. On June 30th, these macOS users will automatically be moved to the ESR channel through application update.

Firefox Macos 10.11

In the meantime, we strongly encourage our users to upgrade to mac OS X 10.12 or higher to benefit from the security and privacy updates.

Firefox Mac Os 10.11

Just bought a new IMAC. It came with El Capitan OSX 10.11.1. I used Time Machine to restore all my data and information. Everything carried over fine, and all my software is working fine. EXCEPT FIREFOX - version 42.0. It hangs up with a blank screen at boot-up. Sometimes it boots and Yahoo my home screen appears, but does not recognize my mouse, and ignores my mouse clicks on everything. Sometimes (Rarely) Firefox boots up. Unfortunately if I get out, the next time I envoke it, the same blank screen etc.I tried to restore Firefox as directed on their support site, but still have same problem. Any suggestions?
