I added several add ons & extensions & ever since I did. I can't open a (new) private browsing window at all. I have customized it to where the "mask" icon to do so is on tool bar & also on "file bar". Sorry, I don't know what you call that where it's File/ Edit/ View / History/ Bookmarks/ Tools/ & Help.? & even if I double click or right click on the 3rd option down under file, nothing happens. I seem to only be able to open A new regular NON- private window by clicking the "+" icon next to each window file tab. Also I can't find anywhere to add any bookmarks. Even if I go to my bookmarks in various ways, & want to click on add to bookmarks, since I can't find the "star" anywhere, it is not highlighted to even give me the option to do so. The only way I can do any of this is if I restart with/by disabling all add ons- which defeats the purpose in the 1st place. Please help me or if you know if or what or which of these may be causing or preventing me from doing this. Thanks for whatever help.
