User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141011015303

Steps to reproduce:

type text anywhere in firefox (including location bar)
visit any site with adobe flash content
select text with the mouse

Actual results:

text is typed very slowly
flash content blinks a lot
text selected becomes not visible (either all-blue or something else)
other similar weird behavior

Expected results:

i switched back to firefox 32.0.3 and it worked perfectly. I'm sure i don't have malware
My notebook is Dell XPS L502X. I use McAfee Security Center; Adobe Flash Player Plugin
Windows 7 SP1 Home Premium 64 bits Brazilian Portuguese (genuine).

I wish to thank you in advance, sorry if my english is poor. I've tried posting on mozilla support with no success. I hope this is the right place to ask fo help.

Like I said if I go back to Firefox 32.0.3 it works perfectly, but that is EOL (means no security updates).

I'll be happy to suply more info if I can manage Thanks!

Thanks a lot!! It worked out I had to update my nvidia drivers, which i did with windows update! For now on I will always check the optional updates... One thing I want to clarify... I posted this bug here because I first tried the Mozilla Support (comunity support), i filled up all the questions but everytime it went back to the begining, in a loop. I tryed it like 7 times.

Today when I went to my emails I was surprised to see there was a confirmation email from mozilla support. IN NO MOMENT THE SITE TOLD ME I NEEDED TO CONFIRM MY EMAIL ADDRESS. So I think this is the real bug after all heheh.

So it's all solved now, THANK YOU VERY MUCH AND A BIG HUGH!

PS: I didn't changed status to solved because i don't know the next question.

I also have the same problem listed here, on a Dell XPS system.  I have updated the video drivers, and it it did not help.  I also have updated Flash.  Firefox is unusable.  Text lags badly.  Webpages with flash blink like crazy, hovering over a link in the links toolbar will make the text disappear, and highlighted text in the search box (toolbar) makes the text disappear.

How can I fix this?  I'd like to downgrade to the last version, if possible.
Have you tryed disabling hardware acceleration? Goto Options-->Advanced-->General and uncheck "Use hardware acceleration when available".

Wish you luck!
Yes, that seems to have helped.  Thanks!
