Back in October 2016, Mozilla announced that starting with Firefox 52 release, it'll will be ending support for browser plugins to ensure "better browser performance, security and improved user experience."
"From animation effects, video playback, drag & drop file upload, clipboard manipulation to interactive 3D games, realtime video chat, now everything can be done without a plug-in," stated Mozilla.
To this end, since Google Hangouts in Firefox currently relies on brower plugins for video and audio calls, Google has notifired that Hangouts users will not be able to make audio or video calls in the browser "temporarily."
Google says, they are actively developing a solution to make Hangouts work in Firefox without needing a plugin.
However, chat on Hangouts will continue to work for Firefox users.
In the meantime, before the Firefox 52 release which is scheduled for March 7, the company says those need to make phone or video calls from Hangouts, are recommended to temporarily switch to one of the following supported browsers:
- Mozilla Firefox ESR
- Google Chrome
- Microsoft Internet Explorer (IE)
Further, Google says, once the fix to support Hangouts on Firefox is in place, a follow-up annoucement will be publish.
For those not aware, "plugins are shared libraries writter using NPAPIm that users can install to display content that the browser can't display natively."
"They can be written completely from scratch using C APIs (usually in C or C++) or can be built on a plugin framework such as Firebreath, JUCE, or QtBrowserPlugin." There are also some code generation tools that may be helpful.
"Plugins are different from extensions, which modify or enhance the functionality of the browser itself. Plugins are also different from search plugins, which plug additional search engines in the search bar."
