The last version stopped working and after an upgrade, nothing works. Add-Ons are absent...it will access internet but the entire browser is messed up.

Question

Was using version prior to latest version 16. Had a problem getting rid of Incredimail search so came here. Instead of doing the reset procedure, I uninstalled-reinstalled Firefox after exporting my bookmarks, etc. I used Revo Uninstaller. That solved the problem of the incredimail issue but went to put my usual add-on's onto browser and that's when the problems started. Last Pass log in button has a small drop down menu I have never seen before..no text just icons. At first the browser showed I had add-ons, but when I would click the options on say: Last Pass, that brought up a menu that was blank. No way to set options. Nothing works. So I reset to original. That didn't work. So...I removed the folder from my programs file and uninstalled Firefox again. Then I upgraded to the latest version...16. Same story. When I click my add-on's, it comes up to the find add-on's, essentially the browser is saying I have none installed. None of my add-on's show up at all. I am probably not making sense here but Firefox will connect and browse the web but that's about it. The add-on's I use, such as, again, Last Pass, are not there. I DO have Windows XP SP3 and my computer is up to date. Don't know if this matters, but I also have Chrome and use some of the same extensions for it that I use for Firefox.

Revo Uninstaller is just that. A simple program(s) uninstaller. When I couldn't get rid of the Incredimail search bar, I used Revo and completely uninstalled version 15 Firefox. Before doing so I exported my bookmarks, etc to another browser.
I reinstalled Firefox, put my add-on's back, just as if it were my first time using Firefox. I had a list of add-on's and extensions and plug-ins showing up on Firefox as was normal. I logged into Last Pass and when I went to set the options, the entire form on the add-on's page was blank. The drop down menu for Last Pass had some weird icons...icon of man and woman, some kind of emoticons...not sure what they were because they weren't marked and they would not do anything once clicked.
After having to copy and paste from Last Pass Vault just to get on my various sites, I reset Firefox. Same problems. I then went to my C:/program files and removed the Mozilla Firefox folder as specified by Mozilla. I then upgraded to 16. Now I don't have any add-on's, just the search for add-ons page. When I tried to add my Last Pass, Clear Preview..etc...they installed but would not show up anywhere on Firefox. I then did another clean uninstall with Revo. I did a clean install for 16 Firefox. Same thing. None of the add-ons I put back show up. I have Windows Professional Edition XP Service Pack 3 and all updates are current. I have Zone Alarm Professional Security Firewall and anti-virus, System Mechanic, Spybot Search and Destroy. I have no idea what is causing my problems. I do use Chrome for some web surfing and I do have many of the same extensions on Chrome that I use(d) on Firefox. Would that interfere? Thanks for the prompt reply!
