Firefox Community Forum

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...

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

Hi there, I'm trying to make a little old machine useful it is an HP mini (Laptop) with an Intel(R) Atom(TM) CPU N455 @ 1.66GHz and 2GB of RAM; it appears the firefox version is too old to install some extensions/add-on like uBlock... I don't want to throw it in the trash; any recommendation please?

Some quite strange questions, which I'm not sure to which category it belongs to, While I use last FF on my main machine, I have another machine that still use firefox 56.0.2 since I like some of the addons there that never been remade/updated to newer FF versions,

It worked fine for years but suddenly all of the addons are disabled no matter what I've tried to do, Using backup, reinstall, about:config and setting xpinstall.signatures.required to false, you name it,

I was wondering if Mozilla pulled the plug on something or if some fixed date for things to expired has arrvied, As well as if there's a way to fix it in the settings/other means?

Some people said that Dev or Nighty edition can actually turn the xpinstall signatures to false while normal FF might have the option but won't actually do it, The problem is that I have no cluse which of their versions is equal to good old 56.0.2, Can anyone tell me?

Thx
