No images loading with FF 41.0.2 / Slow #58

Closed roooots closed 8 years ago

Hi,

I do love Update Scanner and have been using it for more than a year or so. Now since a couple of weeks (unfortunately can' tell how long exactly), the scanner stopped showing images on http://www.ebay-kleinanzeigen.de with my FF41.0.2 on Ubuntu. Furthermore, when the notification pops up, I click on it and the extra 5..15 tabs appear on the tab bar, it will take between 10s and a couple of minutes before all tabs are filled with the respective content.

I've disabled any blocking addons but it did not make a difference.

Any suggestions on where to look for a solution?!

Thanks, roooots

That URL works fine for me, although I'm using FF42 on Ubuntu. It might be that you have another addon installed that is interfering with Update Scanner. Please try with a fresh profile and see if the problem is still present (see https://support.mozilla.org/en-US/kb/Managing%20profiles).

Thanks for the reply! Meanwhile, I'm on FF42 and just tried a fresh profile, with UpdateScan being the first and only plugin installed. Still - same issue here. Any suggestions how to debug?

Thanks, r.

That is puzzling, I can't think of any reason for this.

Is it just this URL that is causing this problem?

roooots commented 8 years ago

Just tried again and - no, it's not the only page. See the attached screeners, the URLs are:

Thanks for your support so far! r.

Ah, both of those URLs use Javascript to load the images. If you disable Javascript and load the pages normally (outside Update Scanner) then you'll see the same effect.

The original URL you posted doesn't contain Javascript, so the images should load correctly in Update Scanner.

There's no easy way of safely supporting Javascript when highlighting changes, but you can always click the "Current Page" view to see the page in all its Javascript glory.

Um ok, I do understand that, in principle. But then why do these pages work fine with Update Scanner on my Win7 PC at work?

Good question! I guess Firefox's implementation around this area must be subtly different on different platforms. It's surprising that Javascript works with highlighted pages under Windows.
