Slow page display on some websites?

(Should probably be moved to the bug report forum, but I'm not registered... could have... too late... sorry...).
Hi,
Since maybe six months (no idea precisely), I have had a slow page display problem on a retailer website (Pixmania.com). I thought it was because they added too much JavaScript or used some bad trick to only show the page when it was fully loaded, but in the past weeks, it started to happen with the Logitech website too (Logitech.com). I'm not completely sure (I certainly do not go to these websites everyday), but I don't think it started at the same time.
I currently use Firefox 11.0 with NoScript 2.3.5, and among other extensions, AdBlock Plus 2.0.3.
Steps for Pixmania:
1) Go to http://www.pixmania.com/ which should show a country selection page, without issue.
2) Allow Pixmania.com and Fotovista.com in NoScript (no issue without JavaScript enabled).
3) Click the French or Spanish flag (it does not happen with the UK or Ireland sites for example), it will quickly show a white page, then rapidly the status bar will say "Done", but nothing will show for 2-3 more seconds.
4) If you click a product category in the top horizontal menu, the same thing will happen (e.g., the first ones, "Photo Caméscope" on the French site, or "Photo Video" on the Spanish one). Same with product pages, and probably all or most pages.
5) Using the back button to go back to a page which displayed the problem will still show a white page for a few seconds. Restarting at step 1 will do the exact same thing (i.e., it does not matter if the page is cached or not -well, I didn't check if there was any page caching on this site, there may not be anyway).
Steps for Logitech:
1) Go to http://www.logitech.com/en-us/home which should show the Logitech homepage without issue.
2) Allow Logitech.com in NoScript.
3) NoScript will reload the page, and a white page will be shown for a few seconds like for Pixmania.
4) Click Products => Mice in the top horizontal menu, same thing.
5) Contrary to Pixmania, using the back button with not exhibit the problem. It will however if revisiting the page though the address bar, even on the same page.
Further tests:
1) It does not happen with Opera 11.60. There is a visible white page transition (probably simply because of heavy pages, it happens on various other sites), but it's very short.
2) I had a few rendering tweaks using "content." options, I removed them from my user.js and reset them in about:config, without change to the problem. Same after restarting Firefox.
3) No change by deactivating NoScript using the "Scripts Globally Allowed" option. Same using the "Disable everywhere" option in AdBlock Plus together.
4) With a new Firefox profile, both Pixmania and Logitech websites work without issue.
5) If I copy my user.js file from my old profile to my new one, and restart Firefox, they both still work without issue.
6) If I reuse my old profile, deactivate both NoScript and AdBlock Plus using the addon manager, and restart Firefox, both sites work without issue.
7) If I only reactivate AdBlock Plus, and restart Firefox, the problem reappears on both websites.
8) If I deactivate AdBlock Plus again, only reactivate NoScript, and restart Firefox, the problem also reappears on both websites.
9) With a new Firefox profile, installing AdBlock Plus alone, and restarting Firefox, both websites work without problem.
10) If I add NoScript to the previous profile, and restart Firefox, the problem comes back.
11) If I remove NoScript, and restart Firefox, on the previous profile, the problem goes away.
12) With a new profile, installing NoScript alone, the problem comes back.
Conclusions:
1) There seems to be some issue with NoScript installed, even with all scripts allowed (but not when scripts are disallowed).
2) Even if NoScript is deactivated in the addon manager, the problem will appear if AdBlock Plus is installed and activated, but not if AdBlock Plus is deactivated in the addon manager too. (I didn't test this issue with a new profile though, but even if various option changes, the behavior seems strange... could there be something not properly deactivated/removed in NoScript, when it is deactivated through the addon manager, which could make AdBlock Plus trigger the issue somehow?).
It's not that big of a problem for me, considering I don't go that often to these two websites, and never seen it with other websites, but I suppose it does happen with some others, and it's of course still quite annoying the few times I go to these websites.
Thanks to anyone who will work on this.
