Firefox 27.0.1 crashes and slow dow, useless for me.I want to change IE, how can I migrating my bookmarks to IE?

Question

I used Firefox for more than 10 years (actual version 27.0.1). Since2-3 days Firefox crashes and slows down. I have already blocked all the additions, without any results. I have completely uninstalled and reinstalled Firefox, the situation remained the same. I can’t really use Firefox support, because I had to wait more than 5 minutes to open the page. I made 2 virus research (MS Security Essential, and MS anti malware) I did not have virus.
I returned to the base state of Firefox, It fonctioned, but after the restart of Windows, it started again slow down.
I tried IE it function well without any problem, but it’s slightly strange for me, but I have to work, so I must use another one if Firefox is dying on my computer.
Unfortunately I have more than hundred important bookmarks in Firefox which are necessary for my daily work, so I can’t simply uninstall Firefox and use IE.
My question: If Firefox is not reparable how can I migrating all my bookmarks to IE?
Thank you in advance for your help and instructions

Answer 1

First of all thank you for your response
I saved all my bookmarks to a library (I have created a library) and I used the importation function of IE, but it was partially successful, more than 70 % of the bookmark has disappeared. I suppose it was a mistake of the conversion made by IE. So I uninstalled and reinstalled again Firefox, thereafter I reinstated the bookmarks.
I suppose, that I found a reason for the crashes and the freezing, probably it was a consequence of the adobe flash player 12. It seems Firefox has a conflict with adobe flash player.
So as conclusion I have trapped between Firefox and IE, Firefox does not work well on my computer, IE work, but without my bookmark and without my usual comfort and customization of my Firefox…
Just a note: during this letter writing, Firefox has slowed down 2 times.
Thank you in advance for your help.
