Good day !

I have an issue that is similar to this : https://support.mozilla.org/en-US/questions/843530 But despite i have provided link ill try to describe it by myself :

This problem appears only in Firefox 20-25 and not in other browsers, and not for all sites ! I don't have a list of them, i have only one. Sometimes when i try to enter http://www.sendflowers.ru Firefox makes a real mess instead of the site: all CSS is loaded but rules from some certain CSS is not used, all dependent elements are not affected by this CSS.

I cant provide useful screenshots right now, but when i meet this problem again, i try to screen it

Little <UPD>ate : when i click on a list CSS in Firebug in tab CSS, i see ALL CSS that is really needed to display site normally, but some of them are empty. I mean when i click on them i see "There are no rules. You can create a rule."

I do not speak or read Russian but the site you link to appears ok to me with text and pictures of flowers which will scroll across the screen similar to a slideshow.

  1. The other question and answes suggested reloaing the web page have you already tried that ?
    Use keyboard keys Control+ F5
  2. I note you have adblock installed is that causing the problem? Try disabling that.
  3. Otherwise try Firefox in SafeMode and make sure you clear the Firefox cache and site cookies. See

Yees, the site looks ok the majority of time, but sometimes it just "forgets" about main.css, for example, and becomes ugly.

1. Reloading does not help,

2. Ok, Adblock is disabled,

3. For a half of an hour after turning safeMode on i haven't seen the problem, but finally it appeared )

And yes, all cookies and cache is deleted, trouble is still sometimes do appear.

I think it is some firefox bug, maybe it will be better if some mozilla developers try to solve the trouble.

Can you reproduce this in a new profile without extensions and other modifications to prefs?

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem.
