after a download of open office i have no bookmarks. a system restore has not replaced them. ive imported an older set from i.e. also when opening firefox it now requires a little resizing to fit the screen.
I lost my Firefox bookmarks yesterday too. It happened after a Winamp crash totally unrelated to Firefox. I had to reset my computer by turning it off. Then when chkdsk was running at startup it indicated that the bookmark file in the FF profile was corrupt.
Search for a file called "bookmarkbackups" it should hold a couple of archive versions. Then open the Firefox Bookmarks manager and use the Import from File wizard to import the last suitable file. Having found a suitable backup with search, I found it easier to copy and past a duplicate to the desktop rather than trawling through endless files with the wizard to dig it out again.
