A lot of the bad reviews are old. This does exactly what I was hoping for. Sure the voice isn't great, but it's the standard one all of them use.
Also, it has a really helpful selecting text feature.

A very good if not one of the best add on for TTS but if i might as i would like the ability to disable the highlighted text as it can be distracting...but good work mate

While it does well not to read every bit of text on the screen like headers and links, it tends to skip major paragraphs and/or become un-synced with what is being highlighted. changing any of the settings restarts the sentence, but since it's down in a ticking scale you HAVE to listen to that each tick.

Doesn't work on Arch Linux

Giving three stars because it works but no more because of the poor customisation options. Overall it's good for visually impaired people.

Doesn't do anything, just infinitely loads :(

finally an extension that actually does what its supposed too, I have been searching for HOURS for a decent reader 10/10, I just wish the voices were better - but other than that, exactly what i wanted

Basically, it does nothing. I think that it didn't install the voices because I don't listen to any voices. I am on Firefox – Arch Linux – Kernel 6.1.12 – x86_64.

I can hear it make sound, and it sounds somewhat robotic, but it's not terrible. It was slow to translate the text on the screen, and it ultimately crashed my computer, so I'm uninstalling it. A language translator with built-in text-to-speech abilities will probably suit me better.

When this screen reader works, it's incredible. I like being able to customize the speech function and clicking where I want the reader to begin. It's intuitive and not riddled with features that convolute the product.

Unfortunately, I run into a lot of times where the addon doesn't begin reading, and will just load and load in a continuous loop of "Loading Audio". This isn't on any particular instance, seems random on random websites. Sometimes it works, and other times it does not. I have also had instances of stopping reading and then resuming a few minutes later - and having the addon resort to non functioning again.

I often have to supplement with a bulky software program that allows similar functions, but is much more difficult to use.

Works great! I have ADHD, so reading through websites is often difficult for me. Having text read out loud to me so that I can read along (or hell, listen to it in the background) is very handy.
I think it would be great if more "reading" websites had native TTS, but that's not a reality yet, so Pericles is a great replacement :-)

(Also, for all your reading-along needs, Pericles lets you change the speed of the narrator, which is awesome.)

Works as expected. Clear voice, good pace, good inflection, even tries to read misspelled words the way they are spelled. Kind of funny once you realize what just happened. :-)

Doesn't work.

this one works but requires too many permissions, it feels to be insecure.

Can be a good help to have a web page read to you, but still limited and with many bugs. Most annoyingly, it seems to treat soft hyphens as word delimiters and split words in the middle if it encounters one. Also falls back to English if it encounters an unknown word, which means my (rather technical) German page is littered with English pronounciations even though these words also exist in German. Still: three stars for being a mostly useful, free accessibility tool - with potential for further improvements :-)
