Large/big page can make the browser freeze
Closed, DuplicatePublic

Description

Visual Editor is not able to edit big pages if we use a small configuration computer.

T71799 speaks about templates editing, but it is the same issue with big pages (for example fr:Histoire du communisme which is too big while reading too).

Evidently, it depends on computer configuration and on page size (proportionately).

Maybe it is a wontfix bug, but I think it is important to define a precise limit because Firefox often shows script warning (too long time execution).

Hi @Pols12, thanks for taking the time to report this!
Unfortunately this report lacks some information. If you have time and can still reproduce the problem, please add a more useful and complete description to this report. Steps to reproduce should allow another person to follow those steps (leaving no room for interpretation) and see the same results.

@Aklapper I understand but it is not a bug but a subjective issue.
You can try this :

  1. Use a relative bad PC (mono-core, 2GHz, 1Go of RAM)
  2. Go to fr:Histoire du communisme with Firefox
  3. Try to edit it with Visual Editor

You will have this error many times. And probably you leave the page before doing edits.

@Pols12: Thanks for clarifying and providing steps to reproduce / setup information!

I also get several "Warning: Unresponsive script" dialogs on that example page, but no crashes.
When exactly does your Firefox browser crash exactly and after which steps?

Pols12 set Security to None.

Sorry, I think I have used a bad word : my browser don't crash, it just freezes.
I assimimated it to a crash because we cannot interact with browser while it works.
But no crash. Sorry.
