firefox runs great, and I keep it updated. When I hit the back button when using google the page goes back to the blank google page not the previous search page
back button when using google search does not always take me back one page but rather to the blank google page for a new search. This does not always occur perhaps 70% of the time. Firefox runs great other then this and I keep it up to date but it has occurred on all versions.

Sorry, this seems to be an issue with Firefox's in-memory cache: when you use a high zoom level on Google with "instant prediction results" (the default setting) then Firefox glitches in redisplaying the page after going back (you may see it for a split second before it blanks out).
Assuming you like your zoom level and like using instant prediction results, then the workaround is to turn off part of Firefox's in-memory caching by changing a setting under the covers.
(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste sess and pause while the list is filtered
(3) Double-click the browser.sessionhistory.max_total_viewers preference and change the value from -1 to 0 (that's a zero).
(Please don't change any other similar-sounding settings to 0 or you may disable Firefox's ability to save/restore your open windows and tabs.)
Then reload the Google results page and test. Fixed? (Or should I say, worked-around?)
