I will try to keep this short. I used to be a long time Firefox user...like since it was first released. I have always had issues with it crashing when having many tabs open. I couldn't take it anymore and jumped ship. After a brief period using Chrome I decided to install version 31 and try it out again. I still have the same exact issues. The issue has persisted across multiple computer builds with increasing power and memory. Currently I am running an i7 4770k with 32GB of RAM and a GTX 770, SSDs, etc. I just installed Firefox yesterday after getting fed up with Chrome and some of its issues. Firefox has crashed about 6-10 times since then. I am a heavy browser. I normally build up tons of open tabs, upwards of 100+ open tabs at once (maybe more, I've never counted). I understand that this can use a lot of memory, but I have a ton of memory. My system utilization does not go above 30% ever, yet Firefox consistently crashes. I'm actually a bit surprised, it seems worse now than it ever has in the past. It crashes, I restore, and it will crash again within 5 minutes. I have no add-ons installed. I had Ad Block Plus installed briefly but I uninstalled that once these crashes started. This is Firefox, no add-ons no extras, nothing else to alter its performance. It crashes constantly. This may just be the final attempt before I go searching elsewhere.
