The functionality:
This will open a desktop app for you after clicking a link. That is it. This doesn't change the way WebEx in the browser functions (tiling still isn't enabled as the screenshot make it appear, etc.) WebEx is still fairly unusable for Linux users, or Mac/Windows users who don't feel comfortable downloading the WebEx client.

The cost:
Webex can see all of your information on any website, ever. They can read your information when you access your bank accounts. They can read your information when you fill out your tax information. They can read anything, at anytime, and store it how they please.

My take: I don't think this is worth it.

Garbage extension, IDK how it got installed and why da heck it demands such ridiculously intrusive permissions

It does nothing? I don't know how to activate it! (Linux Mint 19.2 Cinnamon here.)

Keep in only if you want Cisco to know everything you do on the web. Terrible privacy - it accesses too much and can send it to any one it chooses for essentially any purpose. If you use it delete it immediately after use.

NO Audio happens quite often. Cisco offers no solutions. What good is a webinar with no audio?

Didn't work

When i click a webex-link, this plugin doesn't seem to kick in on my Kubuntu 20.04 with FF

Screen sharing is not working (Firefox 68.8).

Why does this add-on need to access my data for all websites? It seems to just open Cisco WebEx meeting on the desktop app. I find this unjustifiably obtrusive.

Ridiculously intrusive permissions.

NO FUNCIONA EN UBUNTU 16.04 !!! PÉSIMO > : <

I found this addon installed in both my Firefox and Firefox Developer Edition installations (the latter in which I never opened the online Webex Meetings website). Joining an online meeting still works after uninstalling the extension. Therefore, it seems that the extension has no visible use, and asks to access data for all websites.

Don't know what the extension does, if anything.

Useless addon

Doesn't function in Firefox. Probably because Cisco can not get enough of your data through this browser. Don't use web services from companies who think and act like this. Will remove the app from my phone too.

NO FUNCIONA CON UBUNTU 20.04

Does not work on Firefox 75 (Ubuntu 18.04)

Does not support 64-bit systems.

Pas de son !
