Does Firefox actually work and not slow down after about an hour of use for anyone else? I find that it starts to eat up too much memory and CPU and the process eventually starts to hang even navigating between tabs after a while, which is a pretty minimal but trivial action I think. Doesn't do a whole lot of good these security updates if it takes you forever to open up a new tab and google something haha. I used to use firefox a lot too, but they really need to work on performance. Everything I've kept up to date, and I have even disabled the majority of my addons -- no difference in minimizing poor performance noticed.

That and the Rapid Release program were why I switched to Pale Moon.

BTW, another update yesterday -- Firefox version 43.0.1 was released with one change: "Prepare to use SHA-256 signing certificate for Windows builds, to meet new Microsoft signing requirement (1079858)".

There was no update to Firefox ESR.

Firefox version 43.0.2 was released to complete the process started with version 43.0.1 (prepare to use SHA-256), thus making the change: Use a SHA-256 signing certificate for Windows builds, to meet new signing requirements. ESR is also updated. The latest is version 38.5.1.
