Description

[Alexandre Vicenzi]

Attachment: log.txt

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0
Build ID: 20180520220103

Steps to reproduce:

If there's a password input in the page the tab become slow.
This happens in Nightly and Firefox with add-on are disabled or not.

Steps:

- Visit a page that has a password input (https://www.w3schools.com/html/tryit.asp?filename=tryhtml_input_password)
- Go to username input 
- Press tab or click with mouse to fgo to password input
- It will take at least 2 seconds to switch to password field
- Try go back to username
- It will take at least 2 seconds to switch to password field
- Close the tab
- It will take at least 2 seconds to close

Also, right click on password input does not work.



Expected results:

It should switch smooth to other fields.

Just in case, I'm running Ubuntu 18.04 and it was a fresh install. There's nothing else running on computer that could affect performance.

As far as I know and tested this can only be reproduced on Ubuntu, SUSE and Debian works as expected.

The same happens with Firefox 60.0.1 in a Ubuntu 18.

Hi Alexandre,

I tested this issue on Ubuntu 18.04 with FF Nightly 62.0a1(2018-05-23) and I can't reproduce your issue, in my case the switch is almost instantly.

Almost instantly is not the same as instantly. In my case, it's easy to notice that it take a while to switch fields. I can still reproduce with 62.0a1 (2018-05-24) (64-bit).

Unfortunately, I don't have another computer to test, but if you need additional info let me know.

Does the problem go away if you set the preference signon.rememberSignons to false (double-click it) to disable the password manager? This may be a password manager issue.

That's in about:config btw. (it does the same thing as the checkbox in about:preferences#privacy)

Same problem yet. :/

Hmm… just in case, try restart the browser with the password manager disabled and then go to the test page.

I tried to build FF and see if would prompt any errors when running it but I couldn't find anything useful. Anyway, I attached a log, maybe someone can find it useful.

I could try to debug, but I have no idea what should I debug.

I could reproduce the problem in my Ubuntu 18.04, Firefox 60.0.1.

When trying to LogIn in bugzilla Firefox got very slow when I jumped to password field (after entering the user and pressed Tab). It took more than 10 seconds to get back to normal again.

Does the problem go away for either of you set the following preferences in about:config and restart the browser?
* signon.rememberSignons = false
* extensions.formautofill.available = off

Also, the most useful information would be a performance profile. You can follow the instructions at https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem to record one and share the link.

Good Morning,
I also noticed this problem since version 60.0.1, this happens in all sites with password type field.
Freeze for a few moments.

Example in GLPI page: (https://pasteboard.co/HmFmj8Tg.gif)

The problem continues to change,
* signon.rememberSignons = false
* extensions.formautofill.available = off

Info:
Mozilla Firefox 60.0.1
Linux Ubuntu 18.04 4.15.0-22-generic #24-Ubuntu SMP Wed May 16 12:15:17 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Check if this performance log is enough. If not, I can take another.

Thank you! Unfortunately, at first glance I don't see anything relevant in this profile… can you or someone else try again? Make sure you are experiencing the problem when during the recording.

Reminder to reset the signon/formautofill preferences btw.

Same here. Ubuntu 18.04, Firefox 60.0.2 (64-bit)
In my case 5+ seconds to the password field gets the focus.

I think this is a duplicate of bug 1451466 (a new issue in the version of Gnome and ibus in Ubuntu 18.04). And really, it's being tracked externally at https://github.com/ibus/ibus/issues/2002 -- per recent comments there, the ibus maintainer has submitted a patch to Gnome to make things work better.
