T he fire­fox browser has been given a long over­due per­for­mance boost by in­creas­ing the num­ber of me­mory pro­cesses it uses for the first time.

Ver­sion 54 of Mozilla’s browser de­liv­ers – af­ter eight years of de­vel­op­ment – sep­a­rate pro­cesses for each tab, which the­o­ret­i­cally im­proves per­for­mance and sta­bil­ity.

Mul­ti­ple process browser tabs have been an im­por­tant part of Chrome for years, but have the down­side of swal­low­ing sys­tem me­mory as each tab re­quires a sep­a­rate in­stance of the browser’s ren­der­ing en­gine.

Mozilla re­stricts mul­ti­ple pro­cesses to four threads, which it claims is the op­ti­mal num­ber for sys­tems equipped with 8GB of RAM. “If a browser uses too much me­mory, your com­puter may not have enough left to the run the other apps,” claimed Mozilla’s Ryan Pollock.

“Con­versely, if a browser doesn’t use much me­mory, it might not be do­ing some of the things that it could to make your brows­ing ex­pe­ri­ence fast and fluid.”

Mozilla claims its four-thread strat­egy hits the sweet spot be­tween per­for­mance and me­mory hog­ging, and users can al­ter the num­ber of threads if they have enough me­mory.

The an­nounce­ment came as an­other fringe player – Vi­valdi – also launched a re­fresh of its in­ter­face, with the browser for power-users given a fresh, more eas­ily cus­tomised start page.

New fea­tures also in­clude a panel for sort­ing your down­loads and the abil­ity for devel­op­ers to dock tools so they can eas­ily in­spect el­e­ments and test and de­bug code.
