Since yesterday, clicking to read my email gets a blank window, not the email. Same w/ windows where data should be entered (like with online banking). Help!

Question

Since yesterday, when I click to read my email I get a blank window instead of the usual window with the email itself. The same is happening with windows where data should be entered, like those virtual keyboards for online banking login, or windows where you can add records (like daily electricity and gas consumption). In all these situations, a window should pop-up and pop-up it does - but always blank.
I already unistalled/reinstalled Firefox and reset it "to its default state".
Thanks in advance for your help.

Hello,
Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.
Note: ''This will temporarily log you out of all sites you're logged in to.''
To clear cache and cookies do the following:
#Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
#Under "Time range to clear", select "Everything".
#Now, click the arrow next to Details to toggle the Details list active.
#From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else.
#Now click the ''Clear now'' button.
Further information can be found in the [[Clear your cache, history and other personal information in Firefox]] article.
