nice addon!!!

Es un portal, muy bueno

good but make the browser really laggy sometimes

pleasefollow

Not perfect. When we use EASE it allows disabling it on certain http-only sites. But instead of trying to visit http site after disabling, it tries https site, which gives certificate and connection errors. Then we have to remove letter s from address. Also does not allow us to make own rules.

It creates some issues with certain sites. Even if we add them to exceptions, they still can't launch correctly. Disabling this extension fixes it, so despite this great functionality, it limits the experience on the web.
In my opinion, an extension which such stellar recommendation should be better then that, so I'm dissapointed. I'm turning it off.

It's good for desktops but a very power hungry add-on for mobile devices

It has been great until recently, when I started experiencing severe lagging in Firefox and discovered that this extension is a memory hog.

Here's my `top` with HTTPS Everywhere enabled:

PID PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
9036 20 0 14.6g 218564 107332 S 0.0 1.3 0:25.73 WebExtensions

...and when the add-on is disabled:

PID PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
9036 20 0 8970992 199000 107204 S 0.3 1.2 0:26.00 WebExtensions

I have no idea why it needs to commit 14Gb of virtual memory, but that does not sound reasonable at all. I'll keep it switched off for now to see if the overall performance improves.

This was a great add-on when first created, but lack of innovation has made it fall behind over the years. I quit using it a while ago in favor of Smart HTTPS, which does the same thing but provides two very important extra features: it automatically retries without HTTPS if the page fails to load, and it whitelists the site so it won't try again next time. This allows you to have the safety of using HTTPS when possible, but also prevents breakage, which can range from annoying to problematic (in the case of a basic user). It's a shame this add-on never provided similar functionality, as I'd prefer to use it over the other due to being provided by the EFF vs some random developer.
