Hi,

I've accumulated a large whitelist over the years with thousands of entries. Just now I wanted to migrate it to a new laptop (Windows 8.1 Pro x64) via the export/import function (just the list, not the settings - doesn't make any difference to the problem, though). I did a clean install of FF30 and the latest noscript version and when trying to import the whitelist text file (~200KB) firefox just hangs up (doesn't respond even after 5 minutes). I managed to import a shorter whitelist (~100KB) which took some minutes and noscript works as intended - however, doing anything inside the whitelist settings tab (like scrolling) is a huge pain and leads to long hangups. It must be related to the list's length, since a short whitelist (like the stock one upon installation) doesn't cause any performance problems.

I never encountered any problems on Windows 7 machines with large whitelists, everything is responsive (import/export, scrolling through the whitelist), unlike under Windows 8 with otherwise identical settings. Does anyone encounter the same behaviour with large whitelists under Win 8? Can there be a difference between Win 7 and Win 8 how the list is managed and displayed?

Another user with a similar problem found that another extension was the culprit.
Try Standard Diagnostic and see if you can isolate the cause. Please let us know the results.

Also, can you try copying your *entire* Firefox profile from the working machine to the broken machine, and see if the whitelist gets hung then?

Hi,

sorry for the late reply - I'm traveling right now and will be for the next 2 weeks. Thus, I can't test your suggestion copying the entire profile from the (working) win7 machine at the moment. However, I quickly tested whether there are addons or settings interfering (all done on a Win 8.1 Pro ultrabook): I exported the current whitelist (~100KB) which didn't make any problems (it hangs only on scrolling and importing but not exporting, apparently). Then, I created a new firefox profile, didn't change any default settings (apart from showing the menu bar), installed noscript from the addon page, and imported the whitelist. Same result - the import took 2-3 minutes, while FF was hanging at full CPU load, and scrolling the whitelist leads to hangups as described in the start post...

Could it be something about the whitelist's content? There are occasionally some non-ASCII URLs, but other than that I can't imagine what could be wrong. Is there a large whitelist available (known to be "working") which I can test?

Hey, finally since version 2.6.9 the problem is solved and everything runs smoothly! Thanks!
