bug: clicking twice to go back

[Alfred75]

Hi,
with http://www.lemonde.fr and http://www.lefigaro.fr for instance : when I select an article, to go back to the main menu I have to click twice on the go back button:

From the menu of this site (lemonde.fr) I select an article to read it.
I read it.
Then I click on the go back button, to go to the menu. Instead of that I remain on the page of the article, (not at the same place of the page, there is a "movement").
I click a second time on the go back button, then I arrive on the menu, as wanted.

This problem occurs very often, but not all the time. I have not this problem when AdBlock is deactivated.

I use 3 filters : easylist, AdBlock custom filter, French filter.
I have tried with the 3 filters used separately (only 1 at a time) and was not able to reproduce the bug.
After that I have put the 3 filters "on" together. And the bug appeared again...

The problem occurs with the easylist filter and French filter activated together.

Where is the bug ?
