will trigger the warning quite frequently. You should, however, be
able to dismiss it, i.e. a "close" button should be visible. This
doesn't seem to be the case with very long script urls, and I'll
investigate whether this is Mozilla's bug or ours.
I'm not sure whether dial-up is related to this. The script can
only execute once it's fully loaded, but scripts that dynamically
re-load stuff may be affected. This will also be mitigated by
turning off the unresponsive script warning.
The reason they load more slowly now is because your computer is
now executing the code in full, without being prompted, so more
I think what will help you even more is having your computer
reduce the amount of data it must download. Do you use NoScript or
AdBlock Plus? Both are Firefox add-ons which are compatible with
and the amount of ad content that must load.
As far as the oversized alert problem goes, we generally track
Mozilla's updates and this is technically their bug to fix, but it
does disproportionately affect the slower systems that run
TenFourFox and I have repaired Mozilla bugs for them in the past
because it also benefits us. I might add this to our list as we get
spare cycles to work on issues at higher levels than TenFourFox
Flashblock is indeed a good extension, but Flash and all plugins
are disabled by default in TenFourFox anyway. If you turn them on
with the undocumented switch, you are using TenFourFox in an
unsupported state, and plugin code will stop working regardless in
TenFourFox 18+ due to incompatible Mozilla changes.
However, you also make an excellent point about image loading.
This can be a major drain on a dial-up connection. Going to View

style-sheets, which may make the page easier to navigate without
