Firefox was having memory issues late last week and was having to crash 2 or 3 or 4 times a day. When i woke up Sunday and opened-up Firefox, i discovered that Firefox must have automatically updated or something because all my settings had reverted to their default state. But not just default settings: default settings without any of my themes, add-ons, or extensions-- when i hadn't removed them or turned them off. Some of them i was able to re-install, like my preferred theme, but 2 of my favorite and much needed add-ons - Hide Navigation Bar, and Speed Dial - i was not able to re-install because the Firefox add-on page for these 2 add-ons informed that "This add-on is not compatible with your version of Firefox". Yes, I even went into Help / About Firefox, which automatically did a version update, and even that did not allow me to install these 2 add-on. The developer for HNB got back to me and is, i believe, working on it. The contact info for the developer for Speed Dial seems to be invalid. My email to the Speed Dial developer was returned. I need these 2 add-ons more than i need an up-to-date version of a browser. Where do i go to install the version of Firefox that was compatible with these 2 add-ons? - - -Thank you / Jack_Frossed_
