1. it's stable on my win7 system that was upgraded to win7 x64 from winxp x86 which was upgraded from win2000, the earliest files i have are from 2009. this incarnation of hardware was from 2012 when i took the ssd out of my pentium D machine and put it in my new i-7 machine (& did an in-place repair install). it's had hundreds of programs added and removed and various incarnations of firefox since it was called phoenix. i have used the same profile for firefox nightlies (x64) and waterfox. have had some crashes in nightlies forcing me to revert to the day before, but so far waterfox 30 has proven stable. it shares the same default profile with the nightlies too. i gave up on adblock when it started to show memory leaks and sluggish behavior, and showed 'selected' ads. i'm using adguard now.
2. yet again i will say that waterfox is not programmed by mr. alex, it is essentially straight firefox code compiled and optimized by mr. alex but the optimizations are in the compiling not the firefox code. so if you have any desire to curse, curse at mozilla, not here at mr. alex. references to horse excreta are unnecessary and annoying.
3. look to your add-ons. most memory leaks start there. disable them then re-enable them until you find the culprit. when you find it, disable it, or replace it with something else of the same function, until they come out with a new version.
4. about:memory from the address window will also give you more info.Edited by kronckew - 7/18/14 at 1:09am
