    So far, I have flushed the prefetch folder and it seems to have done the trick or alleviate the issue a lot. I am trying to set Superfetch=0 always on each signon, but w10 insists on setting it at its default value (3). Someday I will be totally fed up about Superfetch and I will disable the service altogether. Up to w8.1 you could disable just the Superfetch part of it (thus preserving the prefetch [pf files to load up things faster]. Now it's almost impossible without disabling everything. I never liked Superfetch functionality, specially when using a lot of big apps. Your memory will be trashed eventually, sooner than later, no matter what MS says about it. Damn.

    After a more thorough testing and running with Superfetch disabled (NOT RECOMMENDED AT ALL) I have reduced my history file (places.sqlite) from 20MB to 4,9MB. Things are running a lot smoother now. So it seems the constant disk thrashing was firefox reindexing that file. Maybe there are others though, but so far is running ok.

    Interesting!

    I clear history when closing Fx, so I confess that did not even occur to me.

    I'm glad you resolved the issue.
    Thanks for taking the time to let us know.

    Cheers,

    Goddamnit the issue has resurfaced again after one day. Even if I visit a certain set of webpages, the places file is again 10 MB in size.

    Just chiming in to say that I have found a possible workaround. I downloaded sqlite3 and create the following batch file:

    for %%a in (*.sqlite) do sqlite3.exe %%a vacuum

    That will compact all sqlite databases. I find pretty stupid that CCleaner has got an option to do this but Mozilla doesn't.

    TLR

    After a lot more testing, with FF 41.0.2 I have, at last, pinpointed the issue.

    This page makes FF choke heavily. -> 20minutos.es - El medio social - Última hora, local, España y el mundo (an Spanish newspaper)
    Any idea how to fix it? I have tried tinkering with page permissions but I have noticed no difference.
    As soon as I close the aforementioned page everything works fine.

    If I globally disable AdBlockPlus, everything is better but I got a truckload of garbagety ads.
