Tso, you are a hero ! Like you I was wondering about something cumulative, but thinking more of the cache, as it already caused problems when it grew large in old PC versions of Netscape, a long time ago... My cookie store was over 300KB, mostly ads and tracking cookies of course... once trimmed back to only the useful ones, it is now down to 14K... and my Tear is back to its original speed. Thanks for thinking of this ! I'm glad I posted about my "specific" problem after all :-)
