Firefox Community Forum

When loading webpages, it will often take 60-90 seconds to load the page. I've only seen this happen when loading the page for the first time, once it loads navigating through subpages is seamless. It doesn't seem to be tied to any particular domain, I've had it happen randomly on gaming websites, tech websites, even google searches. The most notable coincidence is that in the networking tab of the developer console, it always(?) takes almost exactly 30 seconds on DNS resolution, 30 seconds on Connecting, sometimes a 30s Blocking element, and then the remainder is near instantaneous; screenshot attached. My network is fine, I'm able to play low-latency games without issue, and Chrome is not exhibiting the same behaviour.

Things I've tried to resolve:

• Restarting computer -- issue has been persisting for months
• Created a new Firefox profile -- still showing the same behaviour
• Disabling all addons/testing Troubleshoot Mode
• Proxy settings in Firefox -- No Proxy and System proxy settings are both showing the behaviour
• Disabling DNS over HTTPS

Any help would be greatly appreciated.

So I have a bunch of Firefox profiles I want to set up a new profile and I want to set up the profile switching with in that profile perhaps by creating a bunch of profiles from the about profiles page and then replacing those profiles with the old ones as I don't see a way to just import old profiles in the UI. How do I go bout doing that like copy and move exactly what exactly where.

Hello, I am from Ukraine and I use a translator, sorry for that. I have poor physical and mental health. I have Windows XP and there is no possibility to buy a newer computer. Yesterday all my browser extensions were disabled. They are very important to me. I accept and understand all the risks. I beg you, please let me use these extensions. Please help...

Hi,

I have a very old version of Firefox (51.0.1 64-bit) on Windows 7 Pro. I know it's well out-of-date. It's not my "main" browser, but there are some things I use it for because there are (were) some handy old extension on it. For example there's an extension that simply copies any text I highlight, without my having to press CTRL-C. I find the "scrapbook" invaluable for saving info offline.

Yesterday everything was fine. Today ALL the extensions have been disable because "[extension] could not be verified for use in firefox and has been disabled". There is no option to enable them again.

I have backups of the extensions (xpi files), but firefox is telling me that they appear to be corrupted.

Is there any way to either enable the disabled extensions, or force firefox to reinstall then from my backups? I have toggled "xpinstall.signatures.required" to "false".

Thanks for any help.

i was browsing youtube and suddenly got an ad, which is how i noticed my add-ons were gone. all of them, not just the ad blocker. and they had still been there like a couple of minutes ago. when i go to download any extension, i've tried a lot of them, it just says "installation aborted because the add-on appears to be corrupt" but it doesn't say what i can do about that. please help!

Dear Support,

I have two laptops - both identical accounts signed in and would like to sync them so that when I open Firefox on laptop 2 it will show me Firefox on laptop 1. and if laptop 2 was last used, then when open laptop 1, it shows me Firefox on laptop 2.

currently it is separate and unique instances.

how do i automate the sync?

thanks, Nicholas
