Mozilla has released Firefox 18.104.22.168 which they are calling a security and stability update. The update patches ten known vulnerabilities three of which are listed as critical. The three critical vulnerabilities patched are:
- MFSA 2008-06 Web browsing history and forward navigation stealing
- MFSA 2008-03 Privilege escalation, XSS, Remote Code Execution
- MFSA 2008-01 Crashes with evidence of memory corruption (rv:22.214.171.124)
I installed the update on both my MacBook, iMac and the Windows machine for my day job. There hasn’t been any noticeable difference on Windows. On my Macs I generally use Safari these days but in a few uses if Firefox I’ve noticed an increase occurrence of it using as much of the CPU as it can get. It’s not like the problem hasn’t occurred with previous versions and it’s not all the time. I don’t use a lot of add-ons but they could also be the cause I suppose.
