hi, could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum (or if it's too long through a site like https://pastebin.mozilla.org/ and provide the link here)?

this might give us a clue what is going on. thank you!

Thanks for your reply.

Have I done it right? https://pastebin.mozilla.org/9085259

yes thank you - unfortunately nothing obvious is sticking out there. could you try updaing your graphics driver through https://support.amd.com/en-us/download/desktop/legacy?product=legacy3&os=Windows%2010%20-%2064 and enabling hardware acceleration? i'd also recommend resetting the browser.tabs.remote.autostart preference, since disabling multi-process mode is no longer a configuration that's supported.

if you continue having problems with langs during text input and scrolling, it would be good if you could capture a few seconds of this with a performance profile like described in https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem you can just put the url you receive when sharing the profile here into a reply on the forum, so our developers could take a look. thanks!

I too am experiencing the same problem.

AFTER THE UPGRADE to 60.0, typing response is lagging in virtually all sites including this page.

I did not change any settings on Firefox prior to the upgrade to 60.0.

I'm on Windows 10 (64-bit). The problem does not occur when using Edge or Chrome.

What's going on?

@aegugka, could you please open a new question and include your troubleshooting information. that would make it easier to look into your particular problem. the question here isn't dealing with slowness that particularily occurred after the firefox 60 update. thank you!

Hi.

This is what I despise about your support.

My issue is the same problem that occurred after the upgrade to Firefox 60 this past week and your question process flow prevents me from posting a new question because it's identical to the question is this discussion flow.

If it'll make it easier, I'll just stop using Firefox like I did until the problem is clearly identified due to more users and rely on Edge and Chrome.

that's why i was providing you with a link in my prior reply to directly post a new question without having to look at related questions again...

Hello again - please can you describe further how I do this. Thanks.

hi aviva21, this is one of the settings that you can access by typing about:config into the address bar (and confirming the warning in case it shows up). then scroll down for this preference and reset it by right-clicking on it.

I checked about:config and I have two instances.

browser.tabs.remote.autostart | default | boolean | true browser.tabs.remote.autostart.2 | modified | Boolean | true

Is this normal?

browser.tabs.remote.autostart.2 was used in previous Firefox versions. Current releases only use browser.tabs.remote.autostart. You can reset browser.tabs.remote.autostart.2 via the right-click context menu to the default value to have this pref removed on the next start.

I did and still lagging and slowdown when typing.

this advice was for the thread owner, whose problem is a different one than yours. i'd ask again: please open a new thread for your issue - https://support.mozilla.org/en-US/questions/new/desktop/fix-problems/form?search=Firefox+is+slow+after+the+latest+update&step=aaq-question
