Firefox Portable

I get an invalid security certificate window for tons of websites. Couldn't find anything on search. Works fine on IE though. How can I fix?

I'm trying to get Firefox 4 Beta7 to run from my usb stick. Every time I install it and try to launch it the splash screen is displayed and then nothing happens. I have tried restarting the PC, reinstalling the app and even different usb sticks, but I cannot get it to load from any of them.

Is there a special method for installing this app that I need to follow? Or is there a fix?

I am an avid user of Firefox and most of the other portableapps software on my USB stick. Recently (since the previous USB stick and my washing machine didn't make it out together) I purchased a 16 Gb Imation and did a NTFS format.

Firefox is now so terrible sloooooooooow in responding that I don't know what to do now..It takes ages to start - the mouse seems to be frozen numerous times.
I can get a cup of coffee, chat with some friends and by that time FF has responded.

When trying to view a shockwave dxr file I get an error:

"This application requires an Xtra (DirectMediaXtra) that either does not exit or failed to initialize properly. Please make sure the appropriate Xtras are in the Xtras folder(s)."

This only happens with some dxr files, not all.

Any help?

thanks

Are there any plugins for Firefox that can read pdf or djvu and that are self-sufficient i.e. independent of any external files, registry etc. ?

I really don't want to open pdf or djvu in any external program.

Look, even Google Chrome has now native support for pdf...

I am experiencing a lot of crashes with PFF 3.6.12. It will suddenly close for no apparent reason. Just wondering if others are experiencing this?
Most likely it is an extension responsible. It is a real chore trying to track down which might be responsible.

Because a couple of issues with the newer Firefox versions and themes that won't work in it, etc., etc., I have had to stay with FF2.

However my Portable FF 2.0.0.3 is now very oudated. I was told there FF2 went up to 2.20. Is there a version of FF2 Portable that goes up that high? I can't find a dl anywhere but perhaps someone here knows. Just until a couple of themes and extensions (ext. that don't work just by changing the max version in the rdf file) catch up to the latest FF.

If anyone knows of a dl link, would appreciate it as after some time googling, no luck my end.

Hi,

I have been using the portable firefox for a while, however I noticed there's a different when searching @ google.
This is what I get at clicking on the background of a search result in the portable version: http://img573.imageshack.us/img573/7309/naamloost.png
I do not have this on my desktop version, can anyone tell me how to enable this? Is this an addon?

Thanks in advance,
