Temporarily allowing scripts causing browser hang

Hi All.
When temp enabling scripts, it reloads the page and this causes a hang on the Internet usage. It seems to affect the other browsers - Opera and pages don't load on startup. The only solution I have is to restart the comp, or reboot the modem. Initially I thought that the problem lay with the ISP but other devices seem to be connecting without any problems.
Any thoughts on this?
Cheers

Yes - you said this:

which means it is not NoScript related (at least not entirely). Please check if disabling NoScript (Tools > Add-ons Manager > NoScript > Disable > Yes, remove ALL protections) changes the situation
in the browser you have NoScript installed and let us know, thanks.

Thanks fr the response. I've been browsing without noscript since then (am unhappy, because of the lower security levels) and haven't had an issue. I just clicked on the button and clicked on allow scripts globally and haven't faced the same problem.
Just to clarify the actual problems and how they occured earlier:
1 OPened Ffox with noscpt enabled
2 navigated to a page which required me to enable script -
3 Clicked on the options button below and ticked temp. allow all on this page
4) the page tried to reload but wasn't able to for another 5 mins ( which is when I gave up)
5 opened opera and startpage wouldn't load
6) disconnected modem and rebooted
went through the same probs (1 to 5 above) again
rebooted the comp and allowed scripts globally.
Hope this clarifies things...
thanks

Well now it seems like the Opera problem could be unrelated to the NoScript problem...
Hmm, the "NoScript reload" tries to read as much from the cache as possible - I wonder if your browser cache is messed up somehow...
What if you disable NoScript's auto-reloading (NoScript Options > General, un-check Automatically reload affected pages... *or* about:config > set noscript.autoReload to false), and manually reload the page after changing script permissions?
Also, does the same problem happen on a new
profile with only NoScript installed and all default settings?

I'll try unchecking the automatic reload option n revert.
I'm not that IT savvy, but purely based on logic, if the browser cache was the issue then Opera should have been working fine IMO?
I've also done a clean install of FF a number of times since this prob surfaced, but it seems to accumulate over time and then I have to do a clean install again, which is a pain.
I'm not sure if there are any conflicts with other installed extensions which are:
Ghostery
cookie cutter
blu hell firewall
web of trust...
Could any of the above be causing a confilct?
Many thanks..

Firefox and Opera are completely different. But I don't know if Opera might try something like to load the start page from cache? In which case that would likely be either your ISP's issue or something with your particular
computer...

Disable Ghostery for testing, it's known to cause problems.
In any case, a new profile as suggested above will help a lot to determine if it's related to one of the other extensions.

I've started a new profile with just no script installed and will test this out.
BTW - I do realise that Opera and FF are completely different

. I was trying to point out that if the reloading from the cache was the problem, then this shouldn't have affected Opera. I did try and open other pages which were not loaded today -bbc for instance, in Opera, but the hang was still happening.

There is no way that NoScript is affecting Opera.
Now that said, a hung process could affect a totally unrelated process.
So if FF itself hangs, possible that another totally unrelated program may fail, until (FF in this case) resolves itself.
(Don't recall any time where a hung FF adversely affected any other programs? Typically have chatzilla open all the time, & if any time FF [SeaMonkey] may have hung, either as a windowed application, or as a process, at no time has chatzilla or other instances of a browser been affected.)
I use Bluhell without incident.
Now some pages, for me, are unusually slow to load when you Temp Allow; MS sites in particular come to mind.

If it's a problem with the way your ISP is passing traffic to/from your computer, or a problem with the way your OS or hardware is interpreting the packets, then it could affect both browsers while the issue is with neither... like if somehow the headers are altered such that there's a problem with caching. I don't know the details but I think something like that is at least theoretically possible. Probably not your case though, given that you said the following quote:

Hmm.. so your problem in Firefox is with cache but in Opera it's with uncached requests?

It's sounding very likely that the problems with your two different browsers are in fact two completely separate issues.
EDIT What extensions you got on your Opera, and what Opera version?

(

I don't run chatzilla in my browser itself, but separately, using FF (cough, version 3.0, I believe) as a backend.
