Same issue here, LastPass extension 4.25.0 on Chrome Version 72.0.3626.121/Windows 10, it is making the Widget screen of a WordPress site unusable. Hope this profiling results helps: https://ibb.co/SsFLKLt

March 2019 and this is still a (very very big!) issue with latest Chrome 73.0.3683.86 (Official Build) (64-bit) on MacOS 10.14.3 & LastPass extension v4.26.0
It renders web sites unusable.

Has LastPass team at least acknowledged the issue?

Having the same issue with extension version 4.26.0 running on Chrome 73.0.3683.103 on Linux. Using a pretty form-heavy SaaS (similar to Google Sheets), and input into the fields can take 4-5 seconds to register from keypress to when the character appears. Profiler shows the extension spending most of that time in the "updateInputMaps" function.

I can confirm that when I disable every extension from Chrome and only enable the LastPass extension today, interactions with complex applications become problematic (we're talking seconds of freezing the application). This only happens for mouse clicks, not keyboard input. I must now disable LastPass on some sites because of this.

I can also confirm this behavior.
Profiling the page in chrome gives that the onloadwff.js script is responsible for the lag.
The method querySelector takes all cpu for a while using the following call stack

Code: Select All Code
querySelector
t
e.getElementLabel
addMappedInput
updateInputMaps
a
Function Call
Timer Fired
Task


Easy to reproduce if you navigate to a site with a lot of input controls (in my case over 12000 checkboxes)

Same problem here.

I've spent weeks in order to understand why my chrome was stucking for specific website.

In the end I've discovered that was because of lastpass extension. Disabling it everything load normally.

Please fix this.

Happening to me too for months and months. Finally got so bad I turned off all extensions and problem immediately went away. As soon as I turned on lastpass, problem came back. Even clicking on a tab to switch tabs is super slow. Only happening for me on mac. Windows seems fine.
