If you go into the options menu, under the "privacy" tab, you can tell it not to remember history at all.

Thanks this is the Clue i was after.
P B refers to Private Browsing {sorry to be confusing {{ i do not like to type /-/
T27 Yeah, that works i guess? it takes me 4eveR to finger it out

.1 ABOUT a month or two ago i switched over to FF from IE ?1
2: i have learNt to use TooLs to Clear Recent History
3? & to Start P B. (however what i reaLLy want to do
------------------
is just turn off the history capture from the beginning (Comprend/-\'?

T27 I do aPeRiciate the.gif however i do not agree with it ACtually

spaceweather M26 AR1302

STEREO x-ray pdxT

AR1302 Appears to me to be in the NORTHERN hemisphere
4me it seams to be that to hit Earth the spot must be south of =
thus A none E eveNT : however the gif i find very interesting Go G

5:30 BBC NEWS T ok tuned in  : in Dam ask US
now where was I 2pm serious : : the .g is so quick the stereo story is
HARD to foLLow BuTT it appears an increase at B should be 9/30 10/1

Gold, silver, and copper

Jears.

Yep... disaster.

26th_NAVYyeah DP People Do believe G.S.C price when UP since
08 never mind
listen in order for those ( i mean THese 3 to work} U must rethink
how much does it take to keep the Earth in Orbit
i hear 13T comming out {per year i guess) thats US
Glow ball may be 7x that oR more say 100T (ok)
thus devide 100 into three piles Rich (AU) Midies(Ag) & Pour(CU) QT
say 80 20 .1 so 80T in gold say 8e8 total sitt'n thus AU /-/p=8e13/8e8
8e5/Oz got it not 2,000 (what a joke} Same song for Au & CU too
get over this Would U

that's the best my slow computer could come up with today | Lots of BS though

i do not see any reports of Volcanic Activity in Japan | i do see it in Italy?

Fuck yeah I love noisy yellow graphs with no labels on the axes!!

M26 GPU
2:4? am PDT weLL its a confusing physics DREAM the
"noisy yellow g" is the ToileT computers Return to Graviity Waves study
A couple of years ago AFTER at least two years of trying i gave up
and turned it off {there were no BIG sun spots }? Etc & & &
now as for the dream Just over so i REMember this it was physics
(about rope) learning the ropes ?{in tree climbing)
the student to my right took my brown manilla rope & left me his
green ?"polly | now where AM i the decent of UR s So later
1ST CLICK PHOTO 2R
T27 REMember there were problems getting 7 "noisy yellow graph" LiNEs
more than two: Two are relativly easy to spot by close eXamination
on the final day 9/22 the first two hours were missing (Tc off)
Thus the third hour(02) is seen three times 00, 01 &02 (see it}?
also the 19th had the same issue. there's at least one other DUPE
however i've not spotted it. & there may be more than 3. I 4get!
Listen? after spending years looking for A match (to X-Rays &2
Stereo too} i as stated got tired & turned it off. A new program
(spectrum) perked my interest & i turned the Toliet Computer back
on. added a second hard drive, installed an old 98 / math ...
revised (serious revision){Ver 7Li} the matlab plot "SCRIPT" &
THAT DID WORK, "OK"? making the conversion much MUCH easier /-/  
It's set to convert 4 weeks on the final day. fig1-4 28days/

Sat 10/1 PINK? yeah Saturday color has been UPgraded to pink
GREEN  is no longer used to designate a day of the week. GREEN will have
some new meaning to me hence forth like RED = odd BLUE  = even & SO

this is ONE number that seams UNlikely to me not to be Miss Leading
i've several Reasons for my doubts about it. 1 i'LL list is 1 digit Depth 8.6

YES: of course i unDerstand.. i'z just Repeating myself


However as the upcoming ?"WINDOW"?
OPENS a few pre thoughts {seam to me to be in order) a 7.0000000
is nothing to sneeze about? sure if ON 141 {4cas4) that's shallow water
if in the Sea at all, depending on Lat. Later maybe a different picture
wiLL emerge. for now the subject REMains TwO DAYS PRIOR to Peri..

Please check it for me and let me know which part is wrong here.
Thank you so much in advance.
Here is the result graph

i had to change things to get the graph
U should be able to see where i made changes by sort(ing) these lines
it appears to me?/?  you think theory & simulate R =
