Why do browsers allow users to open more tabs than it is possible to manage for a good user experience?

Arbitrary limits are bad

Arbitrary boundaries are rarely a good thing. I'm sure there is a limit somewhere (maybe 256 tabs?), But as long as it's far from normal use, most users never know it and the treat as "infinite", which makes it a better user experience.

Having to manage "only 4" or "only 8" or a similar number of documents is very restrictive for the user. For example, classic WordPerfect 5.1 allowed easy simultaneous access to 2 documents. Do you want 3? No chance. Current word processors – no obvious set limit for the user.

The same problem arises in different places:

  • Maximum number of rows or columns in a spreadsheet
  • Maximum size of a free form text field (it is always better to make it so large that the typical user know there is a limit)
  • Maximum number of simultaneous programs running in an operating system – unfortunately, we are experiencing serious memory problems and other unavoidable resources – but the general idea is not to impose arbitrary limits.

And then we come to who actually uses as many tabs in a browser:

Power Users

Obviously, power users do it. Open news, weather, Google, StackExchange, the company's database, as well as several tabs job.

Casual users + bad website design

Some systems will automatically open a new tab for some functions. Well done, it makes a lot of sense. However, some users (do not power users) will continue to return to the "main" tab without closing the new tabs, even if they are done with them, without realizing that they are potentially slowing down their system because of memory and CPU usage (especially if the tabs have a lot of Javascript updates going on).
