LastPass Chrome extension creates invisible iframe that blocks clicks on right side of browser

[shyela]

When I go to some sites (but not all), the LastPass Chrome browser extension creates an invisible iframe that block clicks on the right side of the site in the browser window. Relevant screen shots are below.

Example site with this problem: https://dominion.games/

Example site that does NOT show this problem: https://community.logmein.com/

There are other reports of this same behavior in the Chrome Web Store:

Versions:

OS: Mac OS

Chrome: 107.0.5304.110 (Official Build) (arm64)

LastPass Chrome extension: 4.103.0

Thanks for the report! We have been able to reproduce this and are working on a getting a fix released.

I've seen multiple threads describing the invisible iframe problem going back at least 3 months.  Today, I'm UNABLE to pay my taxes because your iframe is blocking half my pages.

Fix this.

Chrome is up to date

Version 109.0.5414.75

LastPass Extension
Version: 4.107.0

Still experiencing this issue. 

While it's absolutely annoying, deleting the element in chrome inspector works pretty well.

Hello,

I should have mentioned that I'm aware of the workaround, but thank you for the feedback.

The actual fix is to go into the lastpass settings, no, not those setting, not those either, nope, not even those, but go into the settings only available as a link from you lastpass vault itself "Advanced Options" and disable "Use improved save and fill".  

Even though this switch should control how the extension itself behaves, some genius at logmein put it under the "Manage Your Vault" section under "Advanced Options", available only from the vault itself, instead of putting this option under "Extension Preferences".

Hi,

It's been 5 months. 

Any update on this?

If people are not able to pay their taxes, I imagine there are other significant impacts this is causing.

Thanks Matt

Still happening to me. Thanks Matt. But even with your instructions it was hard to find.

Some clarification: it is not under "Account Settings" at all, it is next link under the Account Settings

Just realised that the wording in my post made it even more confusing)

So I just post a link on a screenshot https://imgur.com/a/AuhfYG0
