Hi. After one of the recent updates most websites i go to have striking blue color in the background or elements of it(on tabs etc.). Black letters are almost unreadable in those cases. I installed firefox colors and changed all to my preferences but it doesn't matter it is still the same.If i open same websites in other web browsers they are appearing normal usualy with white instead of blue color. In the snapshots I uploaded you can see an example of firefox and another browser.Please help because I mainly like to use firefox but I will have to change that if I don't find a solution for this issue.Thanks in advance.
