Firefox crashes
Since update 38 Firefox won't work as before. Problems with complements like NoScript, uBlock, etc and even when I refresh Firefox (complete restart without uninstalling; about:support) are doing that Firefox consumes 100% time of CPU.
Problems too with Sync account, like errors in the process and f.e. when FF finishes synchronizing, it freezes and crashes again.
It freezes and have to force exit.
I have to change to Google Chrome as my default browser, thing that I don't like.
I've tried so many things, like in your support page you say (concerned to FF 38: Hardware acceleration, etc, etc) but nothing at all.
Please Help.
OS X 10.9.5- FF 38.0.1

No, there is no need to use "Clear history when Firefox closes". I was just checking if you are using this feature. Try to create a new profile as a test to check if your current profile is causing the problem. See "Creating a profile": If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
Men... I've realized what the problem was... But I will tell you at the end
I've done all stuff that you gave me about profiles, still heavy usage of CPU but not 100% (around 70%). Then I leave for a few minutes and it works (over 4% of CPU usage).
So I transfer the very important data of my old profile and guess what?
It was a nasty tab based on html5 (from my sessionstore tabs) which was causing this huge CPU usage.
So I closed it and things are going well, at the moment.
I'm installing my extensions and I hope not to have major problems... I hope.
Thank u for your assistance and for your support.
P.D.: This was the page in question for your research of implementation of html5 engine of Firefox (Because Chrome opens it with no major problem) (maybe i'm passing of what i just tell, i don't know nothing about) : http://www.emezeta.com/cursos/desarrollo-web-html5/

Oh yes! I have an ID for a crash reported, but I have so many crashes since update 38 that I didn't know what to choose, so I picked the most recent.
ID: a81138b3-77c3-497f-a56e-b06482150519
Because of that (so many crashes) I don't know if this will be useful for anyone of you.
Thx in advance. Regards, Xp4_99
Are you using "Clear history when Firefox closes" to clear any personal data?
- Firefox > Preferences > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings

No, I'm not using these option. Should I use it?
Thank you for your answer and sorry for my English (I'm from Spain).
