Details

I usually have many tabs, like 200-300, and thought that 4-5 MB sessionstore.js was OK. But today I tried this addon https://addons.mozilla.org/en-us/firefox/addon/about-sessionstore/ which can show exactly how many memory each tab cost. So in my log each tab was about 400 bytes, and Google search tabs was 100-500KB each. The more you search with single tab, the more memory it takes in sessionstore.js file. If you open JSON file - many data are in 'storage' field of that tab entry. This leads to huge sessionstore.js file.
Have the same findings in FF 34. Wasn't using the addon to see tab cost, but was trying to reduce the size of sessionstore.js. Sessionstore.js has massive sections of code for each google search tab open. Reduced my file from ~4MB to 111KB by closing about 8-10 google tabs. I have previously had this file as high as 12MB and found instability to restore tabs and had to manually restore from FF's own backups.
