Hmmm, that is weird. Does the problem still persist even after restarting the browser? (and I mean ALL instances of the browser must be closed)
Also, what is the version of Firefox you have running there? (go to "Help -> About Mozilla Firefox " to see)
hmm the version is 1.5.0.5 my problem now is upgrading this version since as iv browsed the repo thread. . i cant anymore see available sites for VL 5.0 - 5.1

i have tried downloading ffox version for slack having the (.tgz) extension.. PLUS the version of ffox in VL 5.8 (.tlz) BUT unforunately . .i cant upgrade the .tlz file. . .

this is the version installed in my VL 5 soho :
[root@vector/var/log/packages]# ls -l firefox-1.15-i586-4vl5
