Installing new add-ons
Firefox wasn't loading webpages properly I tried restarting Firefox then I restarted the computer neither worked. Then I reset Firefox, which solved my issues. Everything transferred over nicely but I had to re download all my add-on's. There was no troubles there either. However when I wanted to add more search engines to the search bar it give me this message "Sorry, you need a Mozilla-based browser (such as Firefox) to install a search plugin." I copies my old search engines over but I can't add any new ones.

by cor-elMake sure that you do not block JavaScript.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
